       Spathicephalus is a genus of early tetrapod that lived‭ ‬during the Carboniferous.‭ ‬Whereas most creatures of its kind had rounded snouts,‭ ‬Spathicephalus is notable for having a roughly square shaped snout when seen from above.‭ ‬The teeth of Spathicephalus are very small and densely packed together,‭ ‬leading to speculation that Spathicephalus may have fed upon aquatic invertebrates,‭ ‬filtering them from the water through their teeth.‭ ‬Analysis of the hyoid process of Spathicephalus suggests that Spathicephalus may have also been a suction feeder,‭ ‬creating sudden low pressure within its mouth to draw smaller aquatic organisms into its mouth.
