‘PLATE XLIV.
Skull of Type of Triceratops Flabellatus (Marsh)’

Plate from my 1907 first edition copy of “The Ceratopsia by John B. Hatcher based on preliminary studies by Othniel C. Marsh.”
Marsh was a paleontologist who named 19 dinosaur genera and published 1,400 scientific papers.

Interesting study of cannabalized Neanderthals.

The Neanderthals eaten were either smaller adult females or juveniles, suggesting they were deliberately and selectively hunted.
