Taxa named by Peter Wilhelm Lund

Smilodon is a genus of extinct felids. It is one of the best-known saber-toothed predators and prehistoric mammals. Although commonly known as the saber-toothed tiger, it was not closely related to the tiger or other modern cats, belonging to the extinct subfamily Machairodontinae, with an estimated date of divergence from the ancestor of living cats around 20 million years ago. Smilodon was one of the last surviving machairodonts alongside Homotherium. Smilodon lived in the Americas during the Pleistocene to early Holocene epoch (2.5 mya – at latest 8,200 years ago). The genus was named in 18

Eremotherium (from Greek for "steppe" or "desert" "beast": ἔρημος "steppe or desert" and θηρίον "beast") is an extinct genus of giant ground sloth in the family Megatheriidae. Eremotherium lived in southern North America, Central America, and northern South America. It was one of the largest sloths, with a body size comparable to elephants, weighing around and measuring about long, slightly larger than its close relative Megatherium.

thumb|Speothos venaticus Speothos is a genus of canid found in Central and South America. The genus includes the living bush dog, Speothos venaticus, and an extinct Pleistocene species, Speothos pacivorus. Unusually, the fossil species was identified and named before the extant species was discovered, with the result that the type species of Speothos is S. pacivorus. S. pacivorus had a larger overall body size and a double-rooted second lower molar. It has been proposed that Speothos originated in the Brazilian highlands sometime during the Pleistocene.
