 In terms of the locality and age of the Dinilysia the fossils can typically be found in abundance in sandstone sediments favored to the Anacleto formation.Additionally, the overall morphological similarities between that of D. patagonica has been used to determine the phylogeny and possible relations of the characteristics which other more present snakes may share.The articulate snake vertebrate fossils were found and studied in terms of the trunks and vertebral morphological variation has allowed for the deduction of that UNC-CIP 1 can be identified in the Dinilysia genus.
