SMU alum partners with Texas to preserve tracks of huge meat-eating dinosaur that roamed San Antonio 110 million years ago.
Houston Chronicle reporter Marvin Pfiefer has written about a project led by SMU alum Thomas L. Adams to catalog and protect the tracks of a 110 million-year-old dinosaur preserved in rock at Government Canyon State Natural Area. Adams, a paleontologist, is a graduate of Dedman College’s Roy M. Huffington Department of Earth Sciences.
Adams is curator of paleontology and geology at the Witte Museum in San Antonio, Texas.
Adams will be joined on the project by other student volunteers from surrounding colleges to team up with the Texas Parks and Wildlife Department to catalog the tracks, which were discovered about 10 years ago.
While at SMU, Adams’ contributions to the field of paleontology included making a 3-D image of Texas’ high-profile Glen Rose dinosaur footprints using portable laser scanning technology. That research was covered by Earth magazine in the 2011 article Mapping Dino Footprints in 3D.
He also identified a 96-million-year-old crocodile Terminonaris making its first appearance in Texas. It’s narrow fossil snout was discovered along the shoreline of a lake near Dallas, which was covered by London’s Daily Mail newspaper in the article Meet the 25 ft prehistoric Texas crocodile who lived 100 million years ago in 2011.

It walked slowly along the tidal flat, looking for something to eat that might have washed up on the shoreline. To its right were the sounds of the surf and the ancestral Gulf of Mexico. To its left was a dense forest.
Acrocanthosaurus, a fearsome meat-eating dinosaur 40 feet long and 16 feet tall, was on the move.
“It’s the size of Tyrannosaurus rex — not as bulky, but as big. And here it is, walking across the beach 110 million years ago in what is now San Antonio,” said Thomas L. Adams, Ph.D., curator of paleontology and geology at the Witte Museum.
It’s a striking discovery: the only publicly known dinosaur tracks in Bexar County. Officials have known about the tracks at Government Canyon State Natural Area for about 10 years, but it wasn’t until this summer that scientists and students began work to catalog and protect them.
Dinosaur tracks might not seem to be as interesting as fossilized bones, but scientists beg to differ.
“The hard parts of the animals that are preserved are remains of dead animals,” Adams told the San Antonio Express-News. “They tell you something about a dead animal.
“This was made by a living animal. He was moving. He was interacting with his environment. It tells you many, many things. It tells you what the shape of its foot was like because in a skeleton we can’t see that. These are the remains of living animals. They tell you a story.”
The Witte is working with the Texas Parks and Wildlife Department, which manages Government Canyon, on a joint project to bring the tracks to the public. Adams and John Koepke, natural area interpreter/volunteer coordinator at Government Canyon, are heading the research.

From dinosaurs to sea turtles, and from technical assistance to advisory roles, SMU faculty and students, the SMU Shuler Museum, and the SMU Innovation Gymnasium have teamed with the nation’s new premier museum of nature and science in Dallas
Fossils on loan by SMU to the new Perot Museum of Nature and Science include those of animals from an ancient sea that once covered Dallas.
The fossils represent a slice of SMU’s scientific collaboration with the Perot Museum and its predecessor, the Dallas Museum of Natural History.
Items from SMU’s scientists include a 35-foot skeletal cast of the African dinosaur Malawisaurus standing sentry in the spacious glass lobby of the Perot, which opened Dec. 1 near downtown Dallas.
“The new museum building itself is an icon, but it’s also a statement by the city about taking the advances of science to the public,” said vertebrate paleontologist Louis L. Jacobs, an SMU Earth Sciences professor, who serves on the Perot Museum’s Advisory Board and Collections Committee.

“Here at SMU we train students and create new knowledge. The museum’s mission is to take the stories of science out to the general public so they can be used,” said Jacobs. “Anthony Fiorillo, Perot Museum Curator of Earth Sciences, is a world-class scientist with whom we work. We have a junction between the mission, training and knowledge we have here, infused into and enhanced by what the museum does. That’s why the museum is important to SMU and that’s why SMU is important to the museum.”
Also on exhibit from SMU is a miniature unmanned autonomous helicopter designed for fighting fires that was built by SMU engineering students.
Herbivorous dinosaur is exhibited with ancient Texas plant fossils Shuler Museum fossils can be viewed in the T. Boone Pickens Life Then and Now Hall. They include an unnamed 113 million-year-old herbivorous dinosaur discovered in 1985 at Proctor Lake southwest of Stephenville, Texas.
For perspective on that exhibit’s paleoenvironment in Texas at the time, SMU paleobotanist Bonnie F. Jacobs provided fossil wood, fossil cones, fossil leaves and images of microscopic pollen grains from the Shuler Museum. The fossils provided information used to create a model of an extinct tree to accompany the exhibit.

Plant fossils inform scientists of the ecological setting in which dinosaurs lived and died, said Bonnie Jacobs, an SMU associate professor in the Huffington Department. Her collaboration with the Perot’s Fiorillo, who also is an adjunct research professor of paleoecology in the SMU Earth sciences department, includes fossil plants from Alaska.
“Understanding past climate and climate change will help us understand what may happen in the future,” she said. Bonnie Jacobs is featured in a Perot Museum Career Inspirations video that is part of the permanent exhibit and also advised on the text of some exhibits.
“The world of the past is a test case for global climate models, which are computer driven,” she said. “If we can reconstruct climates of the ancient Earth accurately, then we can create better models of what may happen in the future.”
Understanding paleoclimate through fossil soils is the expertise of Neil Tabor, an SMU associate professor in the Earth Sciences Department whose Perot Museum video discusses ancient soils, environments and the biggest extinction event in Earth’s history.
Fossils date from period when D/FW was covered by ancient sea The plant fossils are from the geologic period called the Cretaceous, from 146 million years ago to 66 million years ago. They were discovered at the prolific Jones Ranch fossil beds southwest of Fort Worth in Hood County.
At that time, the Jones Ranch — famous as the discovery site of Paluxysaurus jonesi, the state dinosaur of Texas — was not far inland from the muddy coastal shore of a vast shallow sea that a dozen years later would divide North America.
Giant fossil sea turtles were discovered in northeast Texas in 2006 by a 5-year-old girl, Preston Smith. SMU paleontologist Diana Vineyard identified the giant turtles as Toxochelys. (Image: SMU)
Other SMU fossils on loan also date from that period. They include sea turtles, as well as mosasaurs, which were ancient sea lizards that evolved flippers and streamlined bodies for life in the sea.
Stunning examples of fossil sea turtles were discovered in 2006 by a 5 year-old girl, Preston Smith, during a family outing along the North Sulphur River near Ladonia in northeast Texas. The turtles were stacked one on top of the other as if caught in sudden death 80 million years ago.
Diana Vineyard, director of administration and research associate at SMU’s Institute for the Study of Earth and Man, identified the turtles as Toxochelys while an SMU graduate student.
Also on loan from the Shuler Museum, and also identified by Vineyard, are 110-million-year-old sea turtles from the Early Cretaceous of Texas, discovered near Granbury. They represent early specimens in the transition of turtles from land and shallow marine animals to fully developed sea turtles, Vineyard said.
Exhibit includes mosasaur named for the city of Dallas

Michael Polcyn, director of SMU’s Digital Earth Sciences Laboratory, put his expertise to work providing technical assistance for the museum’s Ocean Dallas marine reptile exhibit.
An expert in mosasaurs, Polcyn created digital reconstructions of Dallasaurus, named for the city of Dallas, and physically reconstructed the skeletons of Dallasaurus and another mosasaur, Tethysaurus, for the exhibit.
“The Ocean Dallas exhibit was a great opportunity to showcase the extraordinary story that the rocks in the Dallas area tell us about life in the deep past,” said Polcyn, whose mosasaur fieldwork extends from the United States to Angola.
“It was a great experience working with the museum’s creative and technical professionals on this project,” Polcyn said, “but it should be mentioned that many of the fossils in the exhibit were found by interested citizens walking the local creeks and rivers in search of these beasts, and it is they who deserve tremendous credit for bringing these finds to the public.”
Polcyn, who also is featured in a Perot Museum Career Inspirations video, created a skull reconstruction of the Perot Museum’s duck-billed dinosaur Protohadros, named by former SMU doctoral student Jason Head.
Other SMU fossils include dino footprint, croc egg and giant ammonite
The ammonite Parapuzosia, more than 3 feet in diameter and discovered in Dallas County, is on loan from SMU’s Shuler Museum to the Perot Museum.
SMU vertebrate paleontologist Dale A. Winkler, SMU research professor and director of the Shuler Museum, said other fossils on loan include:
a rare 110 million-year-old crocodile egg discovered with specimens of the crocodile Pachycheilosuchus trinquei west of Glen Rose. Pachycheilosuchus trinquei was named by Jack Rogers, a former SMU student. Rogers also found and identified the egg.
an ammonite, Parapuzosia, more than 3 feet in diameter and discovered in Dallas County.
In 2006, two SMU doctoral students assisted with excavation of the new species of dinosaur named for the museum’s namesakes, Margot and Ross Perot.
The dinosaur, Pachyrhinosaurus perotorum, was discovered by the Perot Museum’s Fiorillo and prepared by Perot Museum researcher Ronald Tykoski.

SMU doctoral student Christopher Strganac and former SMU doctoral student Thomas L. Adams helped dig Pachyrhinosaurus perotorum in Alaska. The only skeletal mount of its kind in the world, the 69 million-year-old skull is on display in the Life Then and Now Hall of the Perot Museum.
Also on view in the museum is a 3D cast of a dinosaur footprint that Adams and Strganac created from the laser scan of a 110 million-year-old fossilized dinosaur footprint, from ichnospecies Eubrontes glenrosensis, that was previously excavated and built into the wall of a bandstand at a Texas courthouse in the 1930s.
Another former SMU doctoral student highlighted among the exhibits is Yoshitsugu Kobayashi, who describes in a video the mentoring he received from the Perot’s Fiorillo while the two worked together in Alaska’s Denali National Park.
SMU’s Shuler Museum is named for Ellis W. Shuler, founder of the University’s geology department. Shuler was a driving force behind the precursor to the Perot Museum, the Dallas Museum of Natural History, established in 1936, said geologist James E. Brooks, SMU professor emeritus and SMU Provost emeritus. Brooks served on the Dallas Museum of Natural History’s board of directors from the 1980s until 2005.
Perot Museum presents a strong scientific face of Dallas “Any first-rate city needs a strong public scientific face with which it’s identified,” Brooks said. “The Perot Museum is going to be that organization.”
Brooks was instrumental in the negotiations with Egypt that enabled the Dallas Museum of Natural History to bring Ramses the Great, its first major exhibit, to Dallas in 1989.
“Museums, in addition to educating children and the general public, also have the responsibility to generate new knowledge, because that makes the city a more intellectually vibrant place,” he said.
Brooks and Louis Jacobs serve on the Perot Museum’s Collections Committee, which serves in an advisory role to Perot Earth Sciences Curator Fiorillo. He and other SMU faculty and staff collaborate on field expeditions to Alaska and Mongolia.
SMU’s Innovation Gymasium contributes to Perot exhibit

SMU’s Innovation Gymnasium is featured in an exhibit in the Texas Instruments Engineering and Innovation Hall at the Perot Museum, said Nathan R. Huntoon, director of the Innovation Gymnasium at the SMU Bobby B. Lyle School of Engineering.
Central to the Engineering and Innovation Hall exhibit is an unmanned autonomous helicopter that can fight fires, built by SMU engineering students.
The Innovation Gym enables SMU students to hone their engineering and creative skills by working on real world, design challenges. Companies, researchers and non-profits all provide real challenges for the students to develop innovative solutions, often under intense time and financial pressure.
The firefighting helicopter featured in the new museum was the first such project.
Accompanying the helicopter is a video demonstration of the helicopter fighting simulated fires, as well as a touch-screen application with interviews of Huntoon and SMU students discussing engineering and innovation.
Huntoon has been a member of the Technology Committee and the Engineering and Innovation Committee for the Perot Museum.
James Quick, a professor of Earth sciences, as well as SMU’s associate vice president for research and dean of graduate studies, applauded the establishment of the Perot Museum, the result of decades of work by many people.
“Every great urban center should have an outstanding museum of nature and science to stimulate the imaginations of people of all ages and attract them to science,” Quick said. “The contribution the Perot Museum will make to North Texas cannot be overstated.” — Margaret Allen

Dallas Morning News reporter Marc Ramirez has written about the big prehistoric crocodile identified by SMU paleontologist Thomas L. Adams, a doctoral candidate in Dedman College’s Roy M. Huffington Department of Earth Sciences.
Making its first appearance in Texas, the genus known as Terminonaris was thought to have originated in Europe, but Adams’ research indicates it now appears to have been a native of the Lone Star State.
The switch in origins for Terminonaris is based on the identification of a well-preserved, narrow fossil snout that was discovered along the shoreline of Lake Lewisville near Dallas.
The 96-million-year-old fossil from Texas is the oldest prehistoric crocodile of its kind in the world, says Adams. A distant cousin of modern crocodiles and alligators, Terminonaris was similar to the modern-day Indian gharial, only much larger.

Thanks to a mail carrier’s discovery, it now appears the Beast from the East was actually a Guest from the West.
About five years ago, Brian Condon got tired of being cooped up at his Lakewood Village home and figured he’d go out and find a fossil.
What he found that day at Lewisville Lake would ultimately brand a supposedly European-based prehistoric crocodile as a native Texan instead.
Meet Terminonaris — a 25-foot-long reptile predating the Lone Star State by about 96 million years.
SMU paleontologist Thomas Adams was among the team that identified the creature. The team’s findings were published in May???s issue of the Journal of Vertebrate Paleontology.
The animal is a cousin to today’s crocodiles and alligators, the largest of which is the saltwater crocodile, which can reach 20 feet in length.
Previously, most of the few known Terminonaris specimens were from North America. The oldest known, however, was linked to a single 94 million-year-old jawbone found in Germany, leading scientists to surmise that the animal had originated in Europe and found its way westward.
That theory has probably been upended, with the Texan croc apparently outdating its German counterpart by about 2 million years.
“We have to really rethink: Did this group really originate in Europe and disperse west?” said Adams, who now has the fossilized snout stored in his office. “Or is it more likely that it originated in Texas?”
The discovery of a local Terminonaris now indicates the animals originated in what is now the southern U.S., then spread north along the shallow Western Interior Seaway, which stretched from what is now the Gulf of Mexico to Canada.
Condon, the amateur collector, was used to finding ammonites and shark teeth near the end of the peninsula dividing the two northern forks of Lewisville Lake. Ten years earlier, he’d found most of a plesiosaur.

He measured 25ft, weighed more than a ton and lived almost 100 million years ago.
A palaeontologist has identified the oldest prehistoric crocodile of its kind in the world after the fossil of a Terminonaris was found at Lake Lewisville near Dallas, Texas.
The realisation by Thomas L. Adams has also changed what we know about the species originally thought to have originated in Europe, because it now appears it was a native of Texas.
Mr Adams, of Southern Methodist University in Dallas, identified the reptile from its long snout which is more than 2ft long and 7in wide, reported Physorg.com.
It was discovered by Dallas amateur fossil enthusiast Brian Condon, who found the heavy pieces of the snout and a vertebrate in 2005 while fossil hunting, and donated them to the university.
Mr Condon had originally thought the pieces were petrified wood.
‘This piece looked like a loaf of bread from Subway,’ he said. ‘It was all wrinkled. Then I picked it up and turned it over and saw it had big round conical teeth. I thought: “This is amazing. It’s a jaw.'”
The discovery of the 96-million-year-old reptile’s fossil suggested that its head would have been about one metre long, Mr Adams said.
The Terminonaris is a cousin of the modern-day Indian gharial but was much larger — and it is a distant cousin of modern-day crocodiles and alligators, reported Southern Methodist University.
Mr Adams revealed the find ‘changes a lot about what we thought we knew about this group.’
‘Now we know the group had a wider distribution range, and that it’s much older,’ he said. ‘It represents a unique find for Texas. This is the first occurrence of Terminonaris in Texas.
‘It’s also the oldest occurrence of Terminonaris in the world and it’s also the southernmost occurrence of Terminonaris anywhere.’
Rare find alters origins and distribution of Terminonaris; first home was Texas and North America — not Europe

Making its first appearance in Texas, a prehistoric crocodile thought to have originated in Europe now appears to have been a native of the Lone Star State.
The switch in origins for the genus known as Terminonaris is based on the identification of a well-preserved, narrow fossil snout that was discovered along the shoreline of a lake near Dallas.
The 96-million-year-old fossil from Texas is the oldest prehistoric crocodile of its kind in the world, according to paleontologist Thomas L. Adams at Southern Methodist University, Dallas, who identified the reptile.
A distant cousin of modern crocodiles and alligators, Terminonaris was similar to the modern-day Indian gharial, only much larger.
“With the recognition of Terminonaris here in Texas, this actually changes a lot about what we thought we knew about this group,” Adams said.
“Now we know the group had a wider distribution range, and that it’s much older. It represents a unique find for Texas. This is the first occurrence of Terminonaris in Texas. It’s also the oldest occurrence of Terminonaris in the world, and it’s also the southernmost occurrence of Terminonaris anywhere.”
There are six other known Terminonaris fossil specimens: five from North America and one from Europe. The European specimen, from Germany, previously was thought to be the oldest. Scientists had concluded that Terminonaris originated in Europe and then traversed the Atlantic and dispersed throughout North America.
Big Texas crocodile swam the shores of North America’s prehistoric seaway Adams identified the reptile primarily from its long snout, which measures more than 2 feet long and 7 inches wide, or 62 centimeters. With a snout that long, Adams estimates the head would have been about one meter long.

“Based on Nile crocodiles and the Indian gharial, which are both large crocodiles, a regression analysis indicates this Terminonaris probably would have been 23 to 25 feet long,” said Adams. “The largest living crocodile today is the saltwater crocodile, which can reach up to 20 feet in length.”
The Texas Terminonaris was an adult and most likely weighed more than a ton, he said.
Adams identified the fossils in “First Occurrence of the Long-Snouted Crocodyliform Terminonaris (Pholidosauridae) from the Woodbine Formation (Cenomanian) of Texas” in the Journal of Vertebrate Paleontology.
Prehistoric crocodiles such as Terminonaris together with living crocodiles make up a large group called crocodyliformes. While technically there are differences between living crocodiles and each of the different types of fossil crocodile forms, all of them are often commonly referred to as crocodiles.
Today there are only 23 species of living crocodiles, a small number compared to the many species of mammals, birds, lizards, snakes and fish alive today, Adams said. That’s in stark contrast to prehistoric times.
“In the past, the crocodilian forms were very diverse and they were very successful. There were hundreds of species. Even at the time of the Texas Terminonaris, they were found everywhere,” Adams said.
Texas specimen fills gap, expands age and range of group Texas Terminonaris was discovered by Dallas-area amateur fossil enthusiast Brian Condon, a rural mail carrier. Condon discovered the heavy pieces of the snout and a vertebrate in 2005 while fossil hunting near his home on Lake Lewisville, a 26,000-acre recreational and fishing lake managed by the U.S. Army Corps of Engineers. He spotted the first of the pieces along the shoreline. Condon donated the fossils to SMU’s Shuler Museum of Paleontology.
In prehistoric times, Texas Terminonaris would have made its home in a marine setting, along the eastern shore of North America’s vast prehistoric Western Interior Seaway. One hundred million years ago the seaway was a wide, shallow sea that split the North American continent in half from the Arctic to the Gulf of Mexico, said Adams, lead author on the scientific article. The seaway would have covered Lake Lewisville’s location.
In its day-to-day life on the seaway, Terminonaris would have kept close to shore, perhaps in a shallow lagoon or estuary, also venturing into the seaway’s warm salty water to hunt for fish. Like modern crocodiles and alligators, Terminonaris would have eaten whatever it could catch, Adams said. Its long, slender snout was well-suited for devouring fish, small mammals and even small dinosaurs.
North America’s other Terminonaris fossil specimens also were found along the seaway. A Kansas specimen is the youngest, about 91 million years, while those from Saskatchewan, Canada, and Montana are 93 million years old. The German specimen is 94 million years old.
“Terminonaris now here in Texas fills in a gap that we didn’t have information for,” Adams said. “It tells us that as a group, as a genus, they were around much longer, because we extend the age back to 96 million years. The range for them is now expanded, because this is the most southern occurrence of them.”
Well-preserved fossil offers no clues to adult reptile’s cause of death While the Texas fossil is well-preserved, how the reptile died remains a mystery since only the snout was found.
It probably died in the water or washed out into the open sea, where it floated to the bottom and was buried very quickly, said Adams. The discovery of seven Terminonaris fossil specimens worldwide is significant, he said.
“To be fossilized, it requires they die at the right time in the right place, be buried very quickly, then eventually be exposed and uncovered,” he said. “So the odds of being fossilized and being found as a fossil are very slim.”
Condon found one piece at the water’s edge of Lake Lewisville. The other pieces were further up a bank that sloped toward the shore, Condon said. The pieces had been deposited on the ground by receding water, pulled from the Woodbine Formation by constant waves that had washed away a soil bank and uncovered the heavy fossils. The outcrop of the Woodbine Formation visible at Lake Lewisville starts at the Red River in North Texas and thins as it nears Dallas.
Condon, who had previously found other fossils in the area, initially thought the pieces were petrified wood.
“This piece looked like a loaf of bread from Subway. It was all wrinkled,” Condon said. “Then I picked it up and turned it over and saw it had teeth — big, round conical teeth — and I thought, ‘This is amazing. It’s a jaw.'”
