"endognathary" – I feel that this could be in violation of WP:TECHNICAL in the lead. I suggest either replacing the word with something less technical or giving greater prominence to the definition, maybe with an explanation of how it is used to handle the food (as long as this can be substantiated from a verified source).
I've added that it means it was used to handle food. Ichthyovenator (talk) 09:09, 4 August 2021 (UTC)Reply
"appendage" – is repeated with proximity in the second paragraph. Is there a synonym that could be used?
I've replaced two instances of "appendage" with "limb". Ichthyovenator (talk) 09:09, 4 August 2021 (UTC)Reply
The lead seems very short. I suggest that it could be expanded based on the verified data in the main body.
