| The Hyoid Apparatus of Liaoxipterus Brachycephalus (Pterosauria) and Its Implications for Food-catching Behavior |
| The feeding behavior of pterosaurs was varied in different groups. Judging by the tooth morphologies and fossilized stomach contents of pterosaurs, the feeding habits included fish-eating, insect-eating, filtering small aquatic organisms, eating shelled crabs and snails, and fruit-eating. Because of the need for survival, they occupied different ecological niches, which determined their different food sources. Herein described is an almost complete, well-preserved hyoid apparatus of Liaoxipterus brachyognathus in comparison with the hyoid apparatus of the modern lizard Chameleon. The long processus lingualis (processus entoglossus) is similar to that of the modern lizard Chameleon, which captures prey by tongue, implying that Liaoxipterus might share a similar lingual feeding behavior. This phenomenon, plus its special tooth morphology, further suggests that it was an insect-eating rather than fish-eating pterosaur. |
