Item A partial skeleton of Pseudaelurus (Carnivora, Felidae) from the Nambé Member of the Tesuque Formation, Española Basin, New Mexico. American Museum novitates ; no. 3342(New York, NY : American Museum of Natural History, 2001) Rothwell, Tom.I describe a partial felid skeleton of Pseudaelurus validus, new species, from the early Miocene, late Hemingfordian of New Mexico. This is the earliest known felid from North America having cranial, upper, and lower dentition as well as postcranial information. A nearly complete set of limb bones provides the first insight into the morphometry of this lynx to puma-sized cat. The skull, similar to that of the earlier European Proailurus lemanensis, displays a high and thin sagittal crest with prominent nuchal crests. In the auditory region, the tympanic bulla architecture resembles that of Proailurus and relates to modern felids. The skeleton includes an articulated manus and pes with an apparently functional first metatarsal bone, hitherto unknown in the genus Pseudaelurus. Log-ratio diagrams are used to compare this skeleton with various extinct and modern felids. Dental morphology, as well as the new postcranial information revealed by this skeleton, is contrasted with that of other felids.Item Phylogenetic systematics of North American Pseudaelurus (Carnivora, Felidae). American Museum novitates ; no. 3403(New York, NY : American Museum of Natural History, 2003) Rothwell, Tom.I review the fossil felid literature, researching the early history of the genus Pseudaelurus in Europe. I examine type Pseudaelurus specimens from Europe, Asia, and North America and emend the generic diagnosis. A large body of new material from the Frick Collection of the American Museum is described and specimens are assigned to one of six species. One species is new and one is transferred from Lynx. New material includes two partial skeletons assigned to two separate species, several skulls, one skull with associated lower jaws and intact basicranium, numerous maxillary and lower jaw specimens, and isolated postcranial items. Cranial, basicranial, and postcranial material of the Frick specimens is compared to that of European taxa as well as to modern felids. A cladistic analysis of 10 taxa and 23 characters produces hypotheses of felid relationships.Item Tributes to Malcolm C. McKenna : his students, his legacy.
