In 1999, Holmes and colleagues described an incomplete specimen of Plioplatecarpus from a non-marine deposit, suggesting that this genus might have entered freshwater and estuarine habitats.[3] While the describers of Pannoniasaurus considered this as 'a stochastic occurrence with no ecological implications',[4] Taylor and colleagues in 2021 considered that this specimen and Pannoniasaurus directly support 'mosasaur inhabitation of coastal and river environments'.[5]
DescriptionEdit
Artist's reconstruction
Plioplatecarpus was a medium-sized mosasaur, with P. marshi measuring 5.5 metres (18 ft) long and P. houzeaui measuring 5–6 metres (16–20 ft) long.[6][7] The eyes of Plioplatecarpus are proportionally larger than those of many mosasaur genera, although the skull is relatively short. The larger eyes may be an adaptation to low light conditions like those found in deeper water. It has fewer teeth than most mosasaurs, but they are greatly recurved. This suggests that Plioplatecarpus would have hunted relatively small prey that it could grab very precisely. The broad distribution of fossil remains in both North America and Europe suggest that it would have been an open ocean predator.[citation needed]
