new saber toothed Cat records felidae machairodontinae for the pleistocene of venezuela and the great american biotic interchange
Journal of Vertebrate Paleontology, 2011Co-Authors: Ascanio D Rincon, Francisco J Prevosti, Gilberto E ParraAbstract:ABSTRACT The Machairodontinae fossil record in South America is not very diverse. Until now, only the genus Smilodon (Smilodontini) has been reported, with likely a single species, S. populator. A second taxon of Machairodontinae was referred to Homotheriini and to the genus Xenosmilus, but the age to which it was assigned, early to middle Pleistocene, is uncertain, because it was recovered out of stratigraphic context. At present, the Venezuelan Saber-Toothed Cat record is limited to the late Pleistocene, and consists of fossils found in Mene de Inciarte (state of Zulia), and from Zumbador cave deposit in the state of Falcon. Here we report a new species of Machairodontinae Homotherium venezuelensis, nov. sp., as well as the first record of Smilodon gracilis in South America. Both were found in El Breal de Orocual, a tar seep in the state of Monagas, northeastern Venezuela. The age of the deposit has been interpreted as early to middle Pleistocene by thermoluminescence dating. We have been able to identi...

a new record of the saber toothed Cat megantereon felidae machairodontinae from an early pleistocene gigantopithecus fauna yanliang cave fusui guangxi south china
Quaternary International, 2014Co-Authors: Min Zhu, Blaine W Schubert, Jinyi Liu, Steven C WallaceAbstract:Abstract Here, we describe Saber-Toothed Cat remains from the early Early Pleistocene (∼2.0 Ma) of Yanliang Cave, Fusui County, Guangxi Province, South China. Specimens, including a complete left dentary and right m1, are identified as Megantereon based on mandibular and dental characters. The Yanliang Megantereon is the smallest representative of the genus from Asia. Overall size, p4 and m1 dental proportions, the disposition of the p3, and dentary measurements align it with characters attributed to Megantereon whitei, a taxon not recorded from eastern Asia or China. Megantereon whitei is thought to be the most derived member of the genus. If the remains are M. whitei, or a closely related form, this represents an early occurrence of the group outside Africa. Other Megantereon specimens from China, that are roughly the same geologic age, or even younger, are considered to have a more primitive dentition than M. whitei. The Yanliang Megantereon, and our review, further demonstrates uncertainty in the evolutionary history of the group, the overall need for tighter chronologic control, and a systematic revision of the genus that includes discrete morphological characters.
