#FossilFriday lithograph of the holotype of Toxodon platensis, a notoungulate from South America, collected by Darwin on the Beagle voyage. The skull is still housed in @NHM_London

#DarwinDay and #FossilFriday so it's gotta be the ground sloth Mylodon darwinii, brought back by Chuck from South America and named for him by ghastly old Richard Owen in 1840.
Lots of preserved skin, nail, tissue and dung known from Patagonia.

Incas, the last Carolina parakeet, died a century ago today in Cincinnati zoo. She died in the same cage that Martha, the last passenger pigeon, died in 4 years earlier. #extinctionisforever
