I’m going to take a #FossilFriday hiatus for a little while this summer (maybe I’ll get to take some more new pictures of fossils!), so I’m leaving you with one of my favorite Haya griva skulls...

I hope that the data contained herein will be a useful springboard for future phylogenetic and paleobiological studies of early-diverging ornithischians.

#Ontogeny #FossilFriday! This display @SamNobleMuseum shows a growth series of claws and thigh bones (femora) from the Jurassic dinosaur Allosaurus! This is why we love to have lots of specimens of the same species—we can learn tons about how these bones changed, inside and out!

Two weeks ago on #FossilFriday, @Cimexomys and I visited the famous Quarry 1 in the OK panhandle, first excavated by J. W. Stovall in 1935. It produced not only a massive Apatosaurus skeleton, but also parts of four Apatosaurus babies and the huge theropod Saurophaganax!
