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: 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: 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: 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: 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: lion dispersal across the Old and New Worlds
OverviewThis overview examines the remarkable dispersal history of the lion lineage, which spread from an African and Eurasian heartland across the Northern Hemisphere during the Pleistocene. Cave lions, Pant…
Research overview: methods for estimating body mass in fossil felids
OverviewThis overview reviews the quantitative methods palaeontologists use to estimate the body mass of extinct cats such as Smilodon, Homotherium, and Panthera atrox. Because soft tissue is not preserved, r…
Research overview: mitochondrial genomes of the cave lion
OverviewThis overview surveys the recovery and analysis of complete mitochondrial genomes from cave lion fossils, which have helped pin down the position of Panthera spelaea within the lion radiation. Mitogen…
Research overview: reconstructing the appearance and mane of the American lion
OverviewThis overview surveys efforts to reconstruct how Panthera atrox looked, including the contentious question of whether males bore a mane like modern African lions. Because the American lion descends fr…
Research overview: taphonomy and entrapment dynamics of the Rancho La Brea tar pits
OverviewThis overview explains why the Rancho La Brea asphalt seeps preserve such an extraordinary concentration of sabertooths and other carnivores. Natural petroleum seeping to the surface forms sticky asph…
Research overview: the American lion at Rancho La Brea
OverviewThis overview examines the record of Panthera atrox at Rancho La Brea, where the American lion is far less common than the sabertooth Smilodon but is nonetheless represented by valuable cranial and po…
Research overview: the cave lion across Beringia and Eurasia
OverviewThis overview examines the vast geographic range of the cave lion, which spread across northern Eurasia and into Beringia and parts of northwestern North America during the Pleistocene. This enormous…
Research overview: the contested identity of the American lion, Panthera atrox
OverviewThis overview examines the long-running debate over what the American lion, Panthera atrox, actually was. Since its description from Pleistocene North America, researchers have variously regarded it a…
The evolutionary history of extinct and living lions
PaperThis study generated genome-scale data from ancient and modern lions, including the extinct cave lion, to reconstruct the deep evolutionary history of the lion lineage. The analyses confirmed that the…
