Comparing cranial biomechanics between Barbourofelis fricki and Smilodon fatalis: Is there a universal killing‐bite among saber‐toothed predators?

The Anatomical Record, EarlyView.
Abstract Saber‐tooths, extinct apex predators with long and blade‐like upper canines, have appeared iteratively at least five times in the evolutionary history of vertebrates. Although saber‐tooths exhibit a relatively diverse range of morphologies, it is widely accepted that all killed their prey using the same predatory behavior. In this study, we CT‐

Unique bone microanatomy reveals ancestry of subterranean specializations in mammals

Evolution Letters, Volume 6, Issue 6, Page 552-561, December 2022., 2022
Abstract Acquiring a subterranean lifestyle entails a substantial shift for many aspects of terrestrial vertebrates’ biology. Although this lifestyle is associated with multiple instances of convergent evolution, the relative success of some subterranean lineages largely remains unexplained.

Growing sabers: Mandibular shape and biomechanical performance trajectories during the ontogeny of Smilodon fatalis

The Anatomical Record, EarlyView.
Abstract The evolution of organisms can be studied through the lens of developmental systems, as the timing of development of morphological features is an important aspect to consider when studying a phenotype. Such data can be challenging to obtain in fossil amniotes owing to the scarcity of their fossil record. However, the numerous remains of Rancho

Hypercanines: Not just for sabertooths

The Anatomical Record, EarlyView.
Abstract Hypercanines are here defined as hypertrophied caniniform teeth, that is, canine teeth that are elongated to serve specific functions in different clades of mammals and their synapsid ancestors. This article presents an overview of the occurrence of hypercanines, their growth, and their function across a broad range of clades.
