Ancient Fauna of Nebraska, 19th Century

Oreodont specimen 

Joseph Leidy (1823 – 1891) was an American paleontologist, professor of anatomy and natural history at University of Pennsylvania and later on the Swarthmore College. Very prolific, wrote several treatises about extinct fauna in North America and was a pioneer on paleontology: named and studied –although discovered by William Parker Foulke- the first complete fossilized skeleton of a dinosaur ever recovered.
Mr. Leidy also announced discoveries on the field of Parasitologism and Protozoologism: In 1846 revealed that trichinosis was caused by a parasite in undercooked meat and published “Fresh-water Rhizopods of North America” in 1879. This codex is a masterpiece, still referenced and studied today around the world.
But probably the most amazing fact on his bio arrived in 1846 as a forensic innovator:  Mr. Leidy became the first person ever to use a microscope to solve a murder mystery, analyzing blood on suspect clothes that finally confessed when Leidy demonstrated the truth.

About the "Ancient Fauna of Nebraska", is a 126 page monograph presenting information on 20 new fossil species, most of these were unique to North America and differed dramatically from known European forms. After a brief introduction of the state of American mammalian paleontology, Leidy presented detailed descriptions and illustrations for a total of 15 mammals and 5 tortoises. Featured among these are an early camel (Poebrotherium wilsoni), an oreodont (Merycoidodon culbertsonii), two rhinos (Hyracodon nebraskensis and Subhyradocon occidentalis), and a sabertooth (Hoplophoneus primaevus).
