Mammoth On The Move: Rare, Nearly-Intact Skeleton Heads To Dallas

Mammuthus columbi, the Columbian mammoth, used to be common in America, but went extinct about 10,000 years ago. The specimen found south of Dallas is estimated to be 20,000 - 40,000 years old.

For tens of thousands of years, the skeleton of a giant mammoth lay in one place: a gravel pit about 50 miles south of Dallas.

A few months ago, the bones were unearthed — and now they're on the move. Paleontologists are carefully packing them up, preparing them to travel to the Perot Museum of Nature and Science, in Dallas.

Research Links Drilling Activities to Water Contamination in North Texas

For years, some residents of Parker County in North Texas have believed that nearby gas drilling was responsible for high levels of methane in neighborhood water wells. Research published today in the Proceedings of the National Academy of Sciences appears to back that up.

The study looked at water contamination in Texas and Pennsylvania. It suggests that faulty cement jobs on drilling wells could be at fault in North Texas. Cement is poured between the rock wall and the steel tubing of oil and gas wells to block contaminants.

“We think either there isn’t enough cement in this location or more likely there are cracks or imperfections in that cement. That’s what allowed the strong gas to move up through the well and then out into peoples drinking water,” says Robert Jackson, a professor of environmental sciences at Stanford, who co-authored of the study.

Three Earthquakes Rattle Texas So Far This Week

Regulators are trying to craft rules to respond to the dramatic uptick in quakes

It’s been a shaky week in Texas with two small earthquakes rattling the Dallas-Fort Worth area and another slightly more powerful quake detected in South Texas.

On Sunday, the first quake measuring magnitude 2.4 struck near Arlington. It prompted some residents to call 9-1-1 after feeling their houses shake and hearing “explosions,” according to the Fort Worth Star Telegram.

Earthquakes are often accompanied by loud “booms,” something that has become a source of anxiety in newly quake-prone parts of the state.
