Who was the real sabertooth predator: Thylacosmilus or Thylacoleo?
The Anatomical Record, EarlyView.Abstract Sabertoothed mammalian predators, all now extinct, were almost exclusively feloid carnivorans (Eutheria, Placentalia): here a couple of extinct metatherian predators are considered in comparison with the placental sabertooths. Thylacosmilus (the “marsupial sabertooth”) and Thylacoleo (the “marsupial lion”) were both relatively large (puma ...

Immediate anterior tooth replacement by using an esthetic fixed bridge: A case report
Medicina Clínica Práctica, 2020 Introduction: Loss of teeth due to extraction is often found in some cases. Preserving interproximal soft tissue and preventing alveolar bone from collapse due to tooth extraction is the most challenging issue. Ovate pontic design can give a natural look

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

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.

Myological and osteological approaches to gape and bite force reconstruction in Smilodon fatalis
The Anatomical Record, EarlyView.Abstract Masticatory gape and bite force are important behavioral and ecological variables. While much has been written about the highly derived masticatory anatomy of Smilodon fatalis, there remains a great deal of debate about their masticatory behaviors.
