Convergent evolution and possible constraint in the posterodorsal retraction of the external nares in pelagic crocodylomorphs
Amongst Mesozoic marine reptiles, metriorhynchid crocodylomorphs were unique in evolving into pelagically adapted forms with little-to-no posterodorsal retraction of the external nares. Narial retraction is a common adaptation seen in sustained swimmers, notably occurring during cetacean evolution. Mesosaurids and the basalmost known members of ichthyosauriforms, thalattosaurians, saurosphargids, sauropterygians, pleurosaurids and... -

‘Ear stones’ in crocodylians: a cross-species comparative and ontogenetic survey of otolith structures
The vestibular system of the inner ear is a crucial sensory organ, involved in the sensation of balance and equilibrium. It consists of three semicircular canals that sense angular rotations of the head and the vestibule that detects linear acceleration and gravity. The vestibule often contains structures, known as the...crocodylia, ontogeny, otolith, inner ear, and vestibular system
