Dufrenoy, justinae (Ammonite)

Dufrenoy, justinae lived in the ancient seas when dinosaurs were still around about 135 mya  (lower Cretaceous Period).  Their fossils have a world wide distribution indicating the theory of continental drift.  Ammonites were very intelligent like their  cousin cephalopops such as octopuses and close relative nautiloids.  They first appeared in the fossil record as early as 400 mya during the Silurian Period.
