In this classic functional study, Akersten proposed the canine shear-bite model for Smilodon, addressing how an animal could use such elongated, blade-like upper canines without snapping them. He argu…

This study recovered mitochondrial genomes from the extinct scimitar-toothed cat Homotherium using ancient DNA, including a specimen from the permafrost, to place the sabertooths relative to living ca…

This systematic study examined the North American species long grouped under Pseudaelurus, the assemblage of stem cats that bridged the earliest felids and the later radiation of modern cats and saber…

This overview surveys Metailurus, a medium-sized cat of the late Miocene and Pliocene that lends its name to the Metailurini, a tribe of machairodonts with only modestly developed sabre canines. Less…

Smilodon, the famous sabertoothed cat of the Americas, is known from abundant fossils such as those at the La Brea tar pits, but its DNA has been difficult to recover from warm-climate deposits. This…

This overview synthesizes the deep-time evolution of cats, from the Oligocene Proailurus and Miocene Pseudaelurus stem felids through the divergence of the conical-toothed Felinae and the sabertoothed…

This overview surveys the Pseudaelurus-grade cats, a diverse assemblage of stem felids that flourished across Eurasia and North America during the Miocene and bridged the dawn cat Proailurus and the l…

This overview surveys the internal classification of the Machairodontinae, the true sabertooth cats within the family Felidae. Researchers commonly divide the subfamily into several tribes: the Smilod…

This overview examines the deep evolutionary divergence within Felidae between the Felinae, the conical-toothed cats that include all living species, and the Machairodontinae, the extinct sabertooths.…
