In Depth

       Dactylosaurus was one of the smallest known pachypleurosaurs,‭ ‬a group of marine reptiles with close associations to the nothosaurs,‭ ‬though opinions differ‭ ‬on if they should belong within the‭ ‬Nothosauroidea or be separate to them.‭ ‬Dactylosaurus may have been fed upon by other marine reptiles and large fish such as primitive sharks like Hybodus,‭ ‬but it would have been a predator of smaller fish itself.
