Ichthyodectidae

 


 

 Xiphactinus - A Cretaceous ichthyodectid.

 

Neopterygian node L: Reduction of spiracular canal, presence of three epurals, appearance of retroarticular and loss of separate surangular.

 

The Jurassic and Cretaceous ichthyodectids, were large ( > 4 metres) predatory fish - as the numerous remains of other fish found in their stomach region illustrates spectacularly. A specimen of Xiphactinus over 4 metres in length has been found bearing the remains of a fish nearly half its size in its stomach.
