Coring reached its total depth this afternoon at 6523 ft. #DeepDust
The Isotope Lab @eapsMIT is a participant in the Anadarko Basin coring project (#DeepDust), supported by @icdpDrilling and @NSF. Coring began on August 16 and exceeded 1 mile as of last weekend. @J_Ramez is on site right now as part of the science team. icdp-online.org/projects/by-…

I joined the Anadarko Basin coring project #DeepDust drill site last weekend. We have gone through more that 500 ft of core in the last couple of mornings with more under way.

A new milestone for the @BowringLabMIT : the 500th sample turret is in the @Isotopx_MS X62 instrument! Turret 001 was loaded in June of 2011.

Only 3 years ago Guadalupian was the worst calibrated epoch of the whole #Permian . Great new progress (and ways to go!): doi.org/10.1016/j.earscirev.…

A key point in the Bagualia #Procb paper was to have precise dates, not only of the dinosaur but for the volcanic event that caused environmental changes. Ash layers were critical but you need to have someone like @J_Ramez from in the team to deal with them!

Study times "the rise of large herbivore dinosaurs at the expense of their evolutionary precursors in the Early Jurassic, which coincided with a major change in ancient plant communities," due to volcanism, warmer climate, says MIT coauthor Jahan Ramezani. bit.ly/3pEdrXq
ALT Newly discovered Bagualia alba (illustrated) is one of the oldest true sauropod fossils ever discovered, dating to 179 million years ago. Like other sauropods, B. alba had powerful jaws and an oversized gut, which helped it consume particularly tough plant material.

Lizard hips vs. bird hips: geological evidence suggests the known dinosaur groups diverged early on, supporting the traditional dinosaur family tree, new research from @MIT EAPS shows.
bit.ly/39G1RTW
ALT The classic dinosaur family tree has two subdivisions of early dinosaurs at its base: the Ornithischians, or bird-hipped dinosaurs, and the Saurischians, or lizard-hipped dinosaurs. In this photo-illustration, a drawing of a bird-hipped Ornithiscian is surrounded by fossils of a Pisanosaurus, a small bipedal dinosaur whose fossils have been analyzed in a new study.
