Continuing on the week's #seaturtle theme with a teaser for tomorrow's paper drop, check out the change in growth strategies between the derived protostegid sea turtle Protostega (first picture), and the more basal protostegid Desmatocheyls (second picture). #ThinSectionThursday

Who needs one Ichthyornis for #FossilFriday when you can have 40?! Self-congratulatory salute to @J_BenitoMoreno et al for a fantastic in-depth look into an awesome near-neornithine bird (even if it can fly).

The distribution of #fossils of the same type of animals on different continents now separated by huge ocean basins provided some of the earliest evidence that all landmasses were once connected as a supercontinent called Panegea. #FossilFriday

#MyScienceMay Favorite jargon

Dinosaur-aged rocks from Kansas are notably devoid of dinosaurs because Kansas was covered by an ocean while dinosaurs ruled on land. Our few #dinosaur fossils are mostly "bloat and float" - they died on land, bloated with gas, then floated to sea.

Tylosaurus nepaeolicus is the middle child of tylosaur #mosasaurs from the Smoky Hill Chalk of Kansas. It is middle in body size, stratigraphic distribution, and phylogenetic placement - sandwiched between T. prorigor (big boi) and T. kansasensis.
