Orpheus Rex


Last time I talked about Erlikosaurus andrewsi, it was Stephan Lautenschlager’s paper with Larry Witmer, Perle Altangerel, and Emily Rayfield discussing the biomechanical aspects of toothloss and beak formation in Erlikosaurus andrewsi.

Toothed Birds


It soars over the tossing waves on enormous, outspread wings. With nary a flap, the bird is soaring dynamically high above the ocean, its eyes scanning the sky around it and sea below. It may seem unremarkable to us today: … Continue reading

Wrench in the Works of Head Attitude


The orientation of the head for standardized anatomical comparison is important for biological and paleontological analysis. It influences anatomical direction, description, the relationship of soft-tissue, study of behaviors such as feeding by the orientation of muscles versus gravity, and so … Continue reading

The Skimmer, Exploded


Rhynchops niger is a fun animal. Not only does it have this wonderfully huge lower bill, there’s lots of fun little structures of the jaw that interact in ways one doesn’t really expect in birds.(The gap in the upper and … Continue reading
