Viverravids
Viverravidae ("ancestors of Viverridae, viverrids") is an extinct monophyletic Family (biology), family of mammals from extinct superfamily Viverravoidea within the clade Carnivoramorpha, that lived from the early Palaeocene to the late Eocene in North America, Europe and Asia.Malcolm C. McKenna, Susan K. Bell: ''Classification of Mammals: Above the Species Level'' in Columbia University Press, New York (1997), 631 Seiten. They were once thought to be the earliest carnivorans and ancestral to extant ones, but now are placed outside the order Carnivora based on cranial morphology (biology), morphology as relatives (a Crown group, plesion-group) to extant carnivorans. General characteristics Xiaoming Wang (paleontologist), Wang and Richard H. Tedford, Tedford propose that they arose in North America 66–60 million years ago, spread to Asia then later to Europe, and were the first carnivoramorphans and possessed the first true pair of carnassial teeth.Wang, Xiaoming; Tedford, Rich ...
