Homo rudolphensis KNM-ER 1470 Skull

Caluromys sp., The woolly opossum, smaller than its North American relative, is an arboreal species dwelling in forests throughout Central and South America. They are omnivorous and will eat fruits, berries, insects, small vertebrates and carrion. This solitary species makes its home in hollowed trees and is said to use its prehensile tail to carry foliage for bedding. Once heavily trapped for its fur, the woolly possum is now of little economic importance. *

Thylacinus cynocephalus., Now extinct, the Tasmanian wolf, also called the Tasmanian tiger, was once hunted as a pest throughout Tasmania and in parts of Australia. The last known wild specimen was shot in 1930. The last captive specimen died in 1936. Although the thylacine, a marsupial, is not a true wolf, it occupied much of the same predatory niche as modern wolves. When compared with the wolf, this species is an excellent example of convergent evolution. Other Names: "Tasmanian Tiger"
