Specifically, six different morphotypes, showing also different morphologic patterns, were identified. The preliminary identification of the trace makers include: crocody...

preserve anatomic structures such as teeth, scales, cephalic and caudal fins, and other fins. The Myliobatiformes order, derived from rays, is characterized by
viviparity and distinctive...
