Evolutionary History of Saber-Toothed Cats Based on Ancient Mitogenomics
PaperThis study recovered complete mitochondrial genomes from the dirk-toothed Smilodon and the scimitar-toothed Homotherium, allowing a genetic test of how these iconic sabertooths relate to one another a…

Phylogeography of lions (Panthera leo ssp.) reveals three distinct taxa and a late Pleistocene reduction in genetic diversity
PaperThis study used ancient and modern DNA to reconstruct the evolutionary relationships and population history of lions, including the extinct American lion and Eurasian cave lion. The genetic data resol…

Rancho La Brea stable isotope biogeochemistry and its implications for the palaeoecology of late Pleistocene, coastal southern California
PaperThis work measured carbon and nitrogen stable isotopes in bone collagen from Rancho La Brea mammals, including the predators Smilodon and Panthera atrox alongside their herbivore prey. The isotopic si…

Research overview: Acinonyx pardinensis, the giant Eurasian cheetah
OverviewThis overview surveys Acinonyx pardinensis, a large extinct cheetah that ranged across Eurasia during the Pliocene and Pleistocene. Considerably bigger than the living cheetah, sometimes approaching t…
Research overview: Machairodus and Amphimachairodus, the great Miocene sabercats
OverviewThis overview surveys Machairodus and its later, larger relative Amphimachairodus, big scimitar-toothed cats that dominated late Miocene predator guilds across Eurasia, Africa, and North America. Thes…
Research overview: Natural Trap Cave and its Ice Age carnivores
OverviewThis overview describes Natural Trap Cave in Wyoming, a deep sinkhole that acted as a pitfall for Pleistocene animals and accumulated a rich fossil assemblage including the American lion, the cheetah-…
Research overview: Panthera gombaszoegensis, the European jaguar
OverviewThis overview surveys Panthera gombaszoegensis, an extinct big cat of the Pleistocene of Europe and western Asia often nicknamed the European jaguar because of similarities to the living jaguar. Known…
Research overview: Panthera spelaea, Panthera fossilis, and cave lion taxonomy
OverviewThis overview surveys the taxonomy of the Eurasian cave lion and its immediate ancestors. The classic Late Pleistocene cave lion is usually called Panthera spelaea, while larger, earlier Middle Pleist…
Research overview: Proailurus, the dawn cat and earliest true felid
OverviewThis overview examines Proailurus, widely regarded as the earliest true cat, known principally from the late Oligocene and early Miocene of Europe, including the famous Quercy fissure fillings of Fran…
Research overview: big cats in the Quaternary megafaunal extinctions
OverviewThis overview surveys the disappearance of numerous large cats, including Smilodon, Homotherium, the American lion, the cave lion, and Miracinonyx, as part of the broader late Quaternary megafaunal ex…
Research overview: body size and extinction selectivity among Ice Age carnivores
OverviewThis overview examines how body size influenced which carnivores survived the end-Pleistocene extinctions and which, like the great cats, did not. Large predators tend to have smaller populations, low…
Research overview: body size and sexual dimorphism in the cave lion
OverviewThis overview surveys what skeletal evidence reveals about the body size of the cave lion and the degree of size difference between the sexes. Panthera spelaea was a large cat, generally exceeding the…
Research overview: body size of the American lion
OverviewThis overview examines the body size of Panthera atrox, frequently cited as one of the largest cats ever to have lived. Reconstructions based on its robust skeleton suggest it exceeded the modern Afri…
Research overview: cave lion coat colour from cubs and genetics
OverviewThis overview surveys efforts to reconstruct the coat colour and appearance of the cave lion using frozen cubs and ancient DNA. The preserved fur of permafrost specimens provides direct evidence of pe…
Research overview: cave lion population structure and genetic lineages
OverviewThis overview examines studies of genetic diversity and population structure within the cave lion, based on ancient DNA from specimens spanning the species' range and time depth. Such analyses have re…
Research overview: cave lions in Upper Paleolithic cave art
OverviewThis overview examines depictions of cave lions in Upper Paleolithic art, most famously the powerful panel of lions at Chauvet Cave in France, along with engravings and figurines from across Ice Age E…
Research overview: conflicting signals in big-cat phylogeny
OverviewThis overview examines why reconstructing the relationships among the living big cats has proven difficult, with different genes and analyses sometimes yielding conflicting trees. The lion, leopard, a…
Research overview: divergence between cave lions and modern lions
OverviewThis overview examines genetic and fossil evidence bearing on when the cave lion lineage split from the ancestors of modern lions. Ancient DNA studies estimate that Panthera spelaea diverged from the…
Research overview: finite-element analysis and the weak-bite paradox
OverviewThis overview surveys how finite-element analysis transformed understanding of sabertooth killing mechanics by revealing an apparent paradox: animals like Smilodon had skulls poorly suited to withstan…
Research overview: geographic range of Panthera atrox in Ice Age North America
OverviewThis overview surveys the distribution of the American lion across Pleistocene North America, where its fossils are known largely from areas south of the great continental ice sheets, extending into p…
Research overview: hyoid anatomy and vocalization in Smilodon
OverviewThis overview reviews what the preserved hyoid bones of Smilodon suggest about the sounds the sabertooth may have made. In living cats, the structure of the hyoid apparatus correlates with whether a s…
Research overview: isotopic and dietary studies of the American lion
OverviewThis overview surveys what stable isotope and dental studies reveal about the diet of Panthera atrox. By analysing carbon and nitrogen values in the bone collagen of American lions alongside contempor…
Research overview: isotopic evidence for cave lion diet
OverviewThis overview surveys stable isotope studies of cave lion diet, which use carbon and nitrogen values in bone collagen to identify the prey of Panthera spelaea across Ice Age Eurasia and Beringia. Seve…
