 Additionally, the ongoing debate of whether snakes evolved on land or in the ocean; certain pieces of evidence point towards oceanic origin based on possible close relationships between snakes and mosasaurs.However, further evidence shows that terrestrial origin is quite possible because of the structure similarities between the inner ear of the Dinilysia and similar burrowing squamate snakes.Based on both the evolutionary and morphological features and similarities that D. Patagonica possess, evidence can be drawn from the features in order to predict the general location of origin.
