Is cranial anatomy indicative of fossoriality? A case study of the mammaliaform Hadrocodium wui

The Anatomical Record, EarlyView.
Abstract Determining the ecology of fossil species presents considerable challenges due to the often fragmentary preservation of specimens. The mammaliaform Hadrocodium wui from the Jurassic of China is known only from the cranium and mandible but may have had a fossorial lifestyle.

The etiology and management of dentinal hypersensitivity

Orapuh Journal, 2021
Dentin hypersensitivity involves loss of the tooth hard tissues leaving the dentin exposed with a short sharp pain response whenever it comes in contact with external stimuli. Above the cement-enamel junction (CEJ), loss of enamel causes dentin exposure.

Dietary ecology of Smilodon across time and space: Additional perspectives from Smilodon gracilis and Smilodon fatalis in Florida

The Anatomical Record, EarlyView.
Dental microwear texture analysis of Smilodon samples from Florida's Pleistocene reveals moderate carcass utilization (like modern African lions) across space and time, with more subtle dietary shifts in response to fluctuating climates. Abstract Smilodon, the iconic saber‐toothed cat, was a Pleistocene apex predator comprised of three morphologically ...
