In the late 1960s, a team led by C.S. Churcher and A. MacS. Stalker collected over 1000 vertebrate fossils, mostly representing large herbivorous mammals, from bluffs along the South Saskatchewan River near Medicine Hat, Alberta, Canada. The records from this area also include the only documented case of the sabre-toothed cat Smilodon fatalis, but these specimens have not been described or illustrated, and therefore, their identification has never been verified. Here, all felid fossils…

Cranial disparity versus diversity in sabertoothed felids: a case of late morphospace saturation
The first diversity (number of taxa) versus disparity (explored morphospace) comparison of sabertoothed felids performed on craniomandibular and dental characters indicates that in machairodont felids real morphospace stabilization is never achieved until the Pleistocene.

This study presents the results of a cladistic study encompassing 45 osteological and dental characters in the skull and mandible, as well as 13 soft‐tissue and behavioural characters, which show the clouded leopard is the most basal pantherine, followed by the snow leopard.
Extinct Beringian wolf morphotype found in the continental U.S. has implications for wolf migration and evolution
The presence of mid‐continental Beringian morphotypes adds important data for untangling the history of immigration and evolution of Canis in North America.

Mitogenomics of the Extinct Cave Lion, Panthera spelaea (Goldfuss, 1810), Resolve its Position within the Panthera Cats
Phylogenetic analysis confirms the placement of the cave lion as the sister taxon to populations of the modern lion ( P. leo), and uses newly recovered stem pantherine fossils to calibrate a molecular clock, highlighting the likely position of this extinct carnivore as a distinct species.
Craniomandibular Morphology and Phylogenetic Affinities of Panthera atrox: Implications for the Evolution and Paleobiology of the Lion Lineage
These studies suggest that previous models of lion biogeography are incorrect, and although lions may have been present in Beringia, they did not penetrate into the American mainland.
Leopard (Panthera pardus) status, distribution, and the research efforts across its range
It is found that while leopard research was increasing, research effort was primarily on the subspecies with the most remaining range whereas subspecies that are most in need of urgent attention were neglected.
