#FossilFriday In many ways Drinker nisti — named after Edward Drinker Cope — is the greatest possible tribute to him: named from scrappy remains, later synonymized with something else, and eventually found to have disappeared completely from its supposed repository under mysterious circumstances

The Princeton University Allosaurus, one of the very first recovered from the Cleveland-Lloyd Dinosaur Quarry. The mount outlived the museum at Guyot Hall before being moved to the university's new enviro sci building a year or two ago. And it's nicknamed Al, because of course it is #FossilFriday

These two ichthyosaurs would end up back on display 30 years later, but in wildly different contexts. Of course, the big one in the back was a brand new species hiding in plain sight (since described by @deanrlomax.bsky.social and Judy Massare)!

Closing out the year with some images of the Academy of Natural Sciences's various dinosaur exhibits through the ages. Someone should really write up a proper history of them one of these days.......(details in alt text)

#FossilFriday observations: both the Sam Noble Oklahoma Museum of Natural History and the New Mexico Museum of Natural History and Science have very-similar-yet-not-identical mounts of Allosaurus anax vs. a big sauropod (Apatosaurus in the OMNH, Diplodocus in the NMMNHS)
