This study estimated body mass across the species of Smilodon using regression relationships between skeletal dimensions and body weight in living felids. The analysis confirmed that the South America…

This 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…

This overview examines Smilodon populator, the largest known sabertooth cat, which roamed the plains and woodlands of Pleistocene South America after felids crossed the Panamanian land bridge. Body-ma…

This 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…

This overview surveys what the claw anatomy of sabertooth cats reveals about how they handled prey. Like living felids, machairodonts had retractile claws, but in robust dirk-toothed forms such as Smi…

This overview surveys dental microwear texture analysis, a method that examines microscopic wear features on tooth surfaces to infer what an animal ate shortly before death. In fossil cats, the techni…

This overview examines the exceptionally powerful forelimbs of Smilodon and what they reveal about how the cat subdued prey. Compared with similarly sized living felids, Smilodon shows thickened limb…

This 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…

This overview addresses how sabertooths like Smilodon achieved the enormous gape needed to clear their elongated canines and apply them to prey. Estimates suggest the jaws could open to roughly twice…

This overview examines mesowear and other gross tooth-wear approaches as applied to extinct cats, which assess the cumulative shape and rounding of cusps to infer long-term dietary abrasiveness and ca…

This 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…

This overview compares the killing strategies of sabertooth cats with those of conical-toothed felids such as modern lions and tigers. Living big cats typically use short, robust canines and a powerfu…

This overview examines whether Smilodon fatalis showed pronounced size differences between males and females, a question with implications for its social system. Because the La Brea sample is large, r…

This overview surveys the stable isotope techniques used to reconstruct the diets of extinct cats. Carbon isotopes in bone and tooth collagen and enamel record whether prey fed on plants using differe…

This 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…

This overview examines the fundamental mechanical compromise that shaped sabertooth skulls: achieving a gape wide enough to clear elongated canines came at the cost of bite force. Opening the jaws to…

This richly illustrated scholarly book synthesizes decades of research on sabertooth cats and their relatives, written and illustrated by a leading palaeoartist and researcher. It surveys the diversit…

This influential book provides a comprehensive illustrated survey of the cat family and its extinct members, combining scientific synthesis with detailed reconstructions of fossil felids and their sab…
