 The information that has been studied and presented from this fossil has brought light to new information regarding the morphological importance of different characteristics within the semicircular canals, as well as the functionality of the olfactory bulb.Through the study of the lightly differentiated castings of the portions of the brain, it was assumed that D. Patagonica was a terrestrial reptile due to the level of development of the olfactory sensory bulb within the casted brain.Therefore, if it had to be deduced for weather snakes, and more specifically, Dinilysia Patagonica adapted terrestrially or aquatically, the presented studies all suggest in one form or another that the features and adaptations present in D. Patagonica are more likely to be those of terrestrial adaptations than those of aquatic adaptations based on not only morphological characteristics, but plesiomorphic and apomorphic shared characteristics to that of current living snake species.
