Research overview: paleopathology and injuries in La Brea Smilodon

This overview surveys the abundant evidence of disease, injury, and skeletal abnormality preserved in Smilodon fatalis from Rancho La Brea. The asphalt deposits yield bones showing healed fractures, arthritis, hip dysplasia, spinal degeneration, and trauma to the limbs and pelvis, offering an unusually rich record of sabertooth health. Researchers use these pathologies to infer how the cats lived: many severe injuries had healed, implying the animals survived long after being incapacitated. The survey discusses how such survival has been cited as indirect evidence for social support, the alternative explanation of resilient solitary recovery, and how large pathology datasets help distinguish congenital conditions from injuries sustained while hunting dangerous megafauna.
