A big, hippo-sized animal with a long snout and tusks — the new species, 23 million years old, has a unique tooth and jaw structure that indicates it was not only a vegetarian, but literally sucked vegetation from shorelines like a vacuum cleaner, said vertebrate paleontologist and study co-author Louis L. Jacobs, Southern Methodist University, Dallas. READ MORE

Professor recounts adventure and discovery in Ethiopia
DALLAS (SMU) – In the movies, the adventure begins when the sinister industrialist abducts Harrison Ford to plan a hunt for lost treasure.
For Bonnie Jacobs, it started with a phone ring.
In the late summer of 2000, the SMU palaeobotanist was working in her office on the third floor of the University’s Heroy Science Hall when an old colleague called with exciting news about Ethiopia. He’d just returned from a dig site where he’d expected to find fossils from eight million years ago. Instead, he’d found fossils from 27 million years ago – mostly plants. He thought it was a job for Jacobs, one of the premier palaeobotanists of African flora.
Although Jacobs had just recently returned from field research in Tanzania, “There is something about Africa that keeps people coming back again and again,” she says. “Much of tropical Africa’s ancient plant history was a mystery, so that’s what attracted me. Not just the romance of exploration, but also because so little was known.”
Africa called, Jacobs answered, and a 15-year adventure in Ethiopia was born. READ MORE

Five months ago geologists from Southern Methodist University identified two wells used to store wastewater from natural gas drilling as the likely cause of a series of earthquakes around the North Texas town of Azle in late 2013.
Now the Texas Railroad Commission is questioning whether they had enough evidence.
In preliminary findings released Thursday, examiners with the commission said there was not sufficient proof the injection well operated by EnerVest, a Houston-based oil and gas company, caused the seismic activity. They recommended the well be allowed to continue operating.
That followed on from a finding last month that another injection well operated by XTO Energy, a subsidiary of oil giant Exxon Mobil, was also not to blame for the earthquakes.
“SMU’s seismology team stands by its research and does not comment on public policy,” a spokeswoman for the university said in a statement. READ MORE

Yet this spring, this was the epicenter of a remarkable tale: a rare, 96-million-year-old dinosaur discovery by 5-year-old Wylie Brys and his father, Dallas Zoo employee Tim Brys.
Wylie and Tim suddenly found themselves thrust into the international spotlight: “Texas boy discovers dinosaur bones,” “Not Your Typical Sandbox Find!” and “Jurassic Jackpot,” the headlines shouted, with reports running on hundreds of media outlets, including the BBC, Huffington Post, Washington Post, Associated Press, U.S. News & World Report, and Time. More than 6.5 million people across the country watched accounts of the father-and-son team. ABC World News Tonight Anchor David Muir even introduced Wylie as the “Jurassic kid.” READ MORE

Residents have reported that the booms aren’t as crisp as a gunshot, and instead sound more like an aerial bomb. A few have speculated that it could be the result of work occurring in an underground mine. READ MORE

FORT WORTH, Texas (AP) — When a big earthquake hits, the world often sees horrific images of collapsed bridges.
In 1989, during a 6.9-magnitude quake in the San Francisco area, the double-deck Nimitz Freeway pancaked, killing 42 people. Fifty-foot sections of the Bay Bridge also collapsed, killing a woman.
North Texas is unlikely to experience an earthquake of that scope, researchers say. But in recent years, the region has experienced dozens of smaller quakes, with the strongest having a magnitude of 4.0 — enough to potentially damage buildings and bridges.
Those in geology and engineering circles are increasingly concerned that the wave of seismic activity in Dallas-Fort Worth could damage the area’s transportation infrastructure — not only bridges but also tunnels, roadways and rail lines.
“We’re talking a lot about it,” Brian Barth, the Fort Worth district engineer for the Texas Department of Transportation, said. “It is important for us to make sure we’re covered. We’ve been discussing it statewide. This isn’t the only area where we’re having these issues.” READ MORE
The SMU Geothermal Lab recently hosted its 7th international energy conference Power Plays:Geothermal Energy in Oil and Gas Fields. Along with discussion on generating geothermal energy from oil and gas fields, topics at this year’s event included desalination, flare gas and induced seismicity.

AUSTIN – Disposal wells that catch the high-pressure byproducts of natural gas drilling cannot conclusively be blamed for an earthquake near Fort Worth this spring, according to state experts.
The Railroad Commission of Texas tested five disposal wells in Johnson County after a 4.0 magnitude temblor on May 7 to assess the effect of injection operations on underground rock formations.
“At this time, there is no conclusive evidence the disposal wells tested were a causal factor in the May 7 seismic event,” the commission said in a statement released on Friday, citing an analysis by its seismologist, geologists and petroleum engineers.
Reports of injection wells elsewhere, however, suggest a link between disposal wells and seismic activity.
In April, a Southern Methodist University-led team found wastewater injection – along with extraction of saltwater from natural gas wells – was the most likely cause of earthquakes in 2013 and 2014 near Azle, west of Fort Worth. READ MORE

Regulators: No Evidence Wells Caused 4.0 Quake
After wrapping up a round of testing, Texas regulators say they have found no evidence that injecting oilfield waste into five disposal wells triggered the largest recorded earthquake in North Texas’ history.
“At this time, there is no conclusive evidence the disposal wells tested were a causal factor in the May 7 seismic event,” the Texas Railroad Commission said Friday in a news release.
Last month, a 4.0-magnitude earthquake hit Johnson County, leading to a few reports of minor damage. It was the most powerful ever recorded in the Barnett Shale region, including more than 50 quakes that have struck since November 2013 — a surge that has coincided with the proliferation of disposal wells, deep resting places for liquid oil and gas waste injected underground at high pressures.
Under rules adopted last year, the Railroad Commission ordered testing at five disposal wells, which the four companies that operate them voluntarily shut down. On Friday, the commission said its analysis of “fall-off pressure”– tests to determine the effects of injections at the well sites – turned up no fault patterns nearby that could have been related to the earthquakes.

First was Oklahoma, which has suddenly become the earthquake capital of the United States. The number of earthquakes with a magnitude of 3.0 or higher more than quadrupled between 2013 and 2014 in the state. The culprit? Scientists are becoming more confident that the injection of wastewater into disposal wells causes fault lines to “slip,” contributing to the likelihood of an earthquake. READ MORE
