Mikrogeophagus

Brachaucheninae Pliosaur, North TX

Turonian, Cretaceous

Jul, 2023

 

Within the subfamily Brachaucheninae, it is unclear whether this tooth belonged to the genus Brachauchenius or Megacephalosaurus, both of which are regarded as some of the final pliosaurs to exist altogether. It is unclear whether convergently adapted Polycotylid plesiosaurs brought about this extinction or simply filled the niche as it opened up.
