Morphological diversity of saber‐tooth upper canines and its functional implications

open access: yesThe Anatomical Record, EarlyView.
Abstract Elongated upper canine teeth, commonly known as saber‐teeth, have evolved three times within the sub‐order Feliformia. The species that wielded them flourished throughout the Cenozoic and have historically been separated into two morphological groups: the dirk‐tooths with longer, flatter canines, and the scimitar‐tooths with shorter, serrated ...

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

open access: yesThe 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

open access: yesThe 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.
