The first tetrapod remains from the Upper Jurassic Talbragar Fossil Fish Bed

A single tetrapod tooth has been recovered from the Upper Jurassic Talbragar Fossil Fish Bed of New South Wales, Australia. It is the first evidence of a tetrapod to have been found at this locality in over 130 years of excavation. The tooth is likely from a temnospondyl amphibian. Herein, we document the discovery, discuss the potential explanations as to why tetrapod remains are so scarce from this locality and provide hypotheses as to how this tooth came to be preserved.
