Cotylocara
Cotylocara is a genus of primitive odontocete from late Oligocene (Chattian) marine deposits of the Chandler Bridge Formation of South Carolina belonging to Xenorophidae.
Cotylocara was capable of echolocation like modern dolphins, as evidenced by its dense, thick and downturned rostrum, air sac fossae, cranial asymmetry, and exceptionally broad maxillae.[1]
