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…

Per Christiansen, John M. Harris · Journal of Morphology · 2005

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 quantified variation in skull and lower-jaw shape across living and extinct cats to understand the patterns and constraints governing felid cranial evolution. Using morphometric analysis of…

Per Christiansen · PLoS ONE · 2008

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…

The carnivore volume of this reference series provides one of the most comprehensive modern species-by-species treatments of the cat family, with detailed accounts of distribution, taxonomy, and natur…

Wilson DE, Mittermeier RA (eds) · Handbook of the Mammals of the World, Vol. 1: Carnivores · 2009

Before the 2017 task force, the most widely cited global checklist of mammal taxonomy was Mammal Species of the World, whose carnivore section codified the accepted list of cat species and subspecies.…

Wozencraft WC (Wilson DE, Reeder DM eds) · Mammal Species of the World, 3rd ed. · 2005

This study examined sex-chromosome DNA sequences to estimate the timing and pattern of diversification across the cat family. By comparing X- and Y-linked markers, which evolve at different rates and…

Pecon-Slattery J, O'Brien SJ · Genetics · 1998

This authoritative review chapter synthesizes the evolutionary history and phylogeny of the cat family, integrating fossil evidence with molecular data to present a comprehensive picture of how cats d…

This overview surveys the Barbourofelidae, a group of sabertooth-bearing carnivores, including the formidable Barbourofelis, that represent yet another independent acquisition of the sabertooth form d…

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…

This overview examines the Nimravidae, an extinct family of cat-like carnivores that independently evolved sabertooth forms long before the true machairodont cats. Though strikingly similar to felids…

This 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…

Complete mitochondrial genomes have been sequenced for most cat species, providing a standardized dataset for phylogenetics, phylogeography, and species identification. This overview surveys the assem…

Integrative taxonomy combines independent data classes (morphology, mitochondrial and nuclear DNA, ecology, biogeography, and behavior) to delimit taxa, and it has become the standard for resolving ca…

Estimating when cat lineages split underpins much of felid systematics and biogeography. This overview explains how molecular clocks, calibrated with fossils, convert genetic distances into divergence…

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 evidence that the family Felidae originated in Eurasia, likely in Asia, before dispersing repeatedly across the world. Combining the fossil record of early cats such as Proailuru…

Modern cats are divided into eight monophyletic lineages: the Panthera lineage (lions, tigers, leopards, jaguars, snow leopards, clouded leopards), the bay cat lineage, the caracal lineage, the ocelot…

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.…

Modern classifications divide living cats into two subfamilies: Pantherinae (the roaring and big cats plus clouded leopards) and Felinae (most small and medium cats). This overview explains how that s…

This comprehensive study screened thousands of samples from many felid species plus hyenas for feline immunodeficiency virus and sequenced isolates to map viral diversity. The authors confirmed that F…
