This study supports the inference by W. Akersten that the main muscles inserting in the mastoid process in sabretooths were those originating in the atlas, rather than those from the posterior neck, sternum and forelimb, and implies larger and longer-fibred atlanto-mastoid muscles than in pantherines.
Aspects of the functional morphology in the cranial and cervical skeleton of the sabre‐toothed cat Paramachairodus ogygia (Kaup, 1832) (Felidae, Machairodontinae) from the Late Miocene of Spain:…
The skull and cervical anatomy of the sabre-toothed felid Paramachairodus ogygia (Kaup, 1832) is described in this paper, with special attention paid to its functional morphology. Because of the…

A new genus and species of felid, Ginsburgsmilus napakensis, is described from Napak, Uganda and a close relationship is proposed between these two genera and the tribe Barbourofelini, the transition between the two being represented in the fossil record by Prosansanosmilus peregrinus Heizmann et al. 1980.

It seems that, whereas the false thumb of the giant panda probably evolved for manipulating bamboo, the false thumbs of the red panda and of S. batalleri more likely evolved as an aid for arboreal locomotion, with thered panda secondarily developing its ability for item manipulation and thus producing one of the most dramatic cases of convergence among vertebrates.
Implications of the functional anatomy of the hand and forearm of Ailurus fulgens (Carnivora, Ailuridae) for the evolution of the ‘false‐thumb’ in pandas
The functional anatomy of this structure in the red panda is studied, comparing it with existing descriptions of the grasping mechanism in both pandas, and it is shown that previous interpretations of the radial sesamoid in Ailurus as a rod‐like structure without direct articulation to the wrist bones are inaccurate.
A complete skull of Chasmaporthetes lunensis (Carnivora, Hyaenidae) from the Spanish Pliocene site of La Puebla de Valverde (Teruel)
Overall, the available evidence suggests that C. lunensis was an active, group hunting predator of medium-sized ungulates, able to fully utilize carcasses but less dedicated to scavenging than the contemporary species P. perrieri.
Systematic revision of the Late Miocene sabre‐toothed felid Paramachaerodus in Spain
The population from Batallones-1 constitutes a clearly different form from the genus Paramachaerodus, and it is proposed to be inclusion in the genus Promegantereon Kretzoi, 1938, together with an upper canine from Crevillente-2 (MN 11), very similar to those from Bat allens-1.
Functional anatomy of the forelimb in Promegantereon* ogygia (Felidae, Machairodontinae, Smilodontini) from the Late Miocene of Spain and the origins of the sabre‐toothed felid model
These adaptations reached their highest development in the more advanced sabre‐toothed cats of the Plio‐Pleistocene, such as Smilodon and Homotherium, although having very different body proportions, these later animals developed such extremely powerful forelimbs that they were probably able to capture relatively larger prey than extant pantherins.
Ailurid carnivoran mammal Simocyon from the late Miocene of Spain and the systematics of the genus
The most complete and best−preserved materials assigned to Simocyon from Spain are described and a differential di− agnosis forSimocyon batalleri is proposed, which is morphologically intermediate between the more primitive S. diaphorus and the more derived S. primigenius.
FIRST KNOWN COMPLETE SKULLS OF THE SCIMITAR-TOOTHED CAT MACHAIRODUS APHANISTUS (FELIDAE, CARNIVORA) FROM THE SPANISH LATE MIOCENE SITE OF BATALLONES-1
Differences in cranial morphology suggest separation at the generic level between M. aphanistus and M. giganteus, suggesting that the specialized canines of M. ansonistus were used within the context of a biting mechanism more similar to the canine bite of modern felids.
