UT researchers uncover Jurassic fossils beforehand unfound in Texas

A workforce of scientists at UT in collaboration with scientists from Southern Methodist College found the primary Jurassic vertebrate fossils in Texas within the Malone Mountains close to the Texas-Mexico border. 

The Jurassic interval lasted from about 145 million years in the past to 200 million years in the past and is a geologic age marked by the presence of dinosaurs. Vertebrates are animals with a spine. What scientists suppose to have found are the fossils of a marine Jurassic reptile known as a plesiosaur, mentioned spearhead of the expedition Steven Might. 

“It’s not too shocking that that’s what we discovered as a result of simply throughout the border in Mexico, there’s been a good variety of fossil vertebrates discovered within the age equal rocks,” mentioned Might, analysis affiliate on the Jackson College of Geosciences Museum of Earth Historical past. “In these rocks, they discovered plesiosaurs they usually discovered ichthyosaurs, that are form of like dolphin-looking animals, however they had been additionally marine reptiles.”

Might started his search when he began engaged on a ebook that chronicles an summary of vertebrate fossils in Texas by geological age. He mentioned there aren’t many uncovered Jurassic rocks in Texas wanted to seek out the fossils, however that Jurassic invertebrate fossils similar to snails, clams and ammonites had been recorded within the Malone Mountains of West Texas.

Might mentioned he discovered the concept to go to the Malone Mountains when studying by a paper revealed in 1938 by Claude O’Brien discussing “giant bone fragments” that caught his consideration and led him to exit and discover.

Might mentioned he and his workforce imagine {that a} small arm of the Pacific Ocean known as the Chihuahua Trough made its approach to the westernmost a part of Texas the place the Malone Mountains are, which means that not like a lot of the state through the Jurassic interval, this half was coated in shallow ocean. 

Though a big discovery, Might mentioned that it’s only the start of discovering what all is on the market within the Malone Mountains. He mentioned they solely prospected a number of sq. miles of the whole 13 sq. miles of the mountain formation on account of a lot of it being within the inside of the pretty distant vary. 

“We’re fairly near the shoreline, so it’s attainable that even among the extra form of typical terrestrial dinosaurs might have died and been washed out into these shallow marine settings,” Might mentioned. “You may discover a entire suite of the form of basic late Jurassic dinosaurs that we see farther north … basic dinosaurs like allosauruses, stegosauruses and that form of dinosaur.” 

Might and his colleagues revealed a paper final month describing what they discovered whereas in West Texas. He mentioned they had been solely capable of finding these fossils due to the permission and good graces of the Texas Normal Land Workplace, but additionally because of the native landowners who supported their endeavors. 

“We hope now that we’ve put this paper out and have mentioned, ‘Hey, there are Jurassic vertebrates in Texas,’ hopefully others will decide up that problem and head on the market and proceed the exploration,” Might mentioned.
