Dolichorynchops bonneri

Fast and agile, this short-necked plesiosaur was wider than long. The Dolichorhynchops’ conical, interlocking teeth were perfect for capturing fish. The adult is cast from a virtually complete skeleton. The baby was sculpted using the adult as a guide and adjusting for expected allometry.
