Tetraodontidae (Puffer fish) gill plates SITE LOCATION: Pungo River or Yorktown Formation, Aurora, Beaufort Co., North Carolina, USA TIME PERIOD: Miocene age (5.3-23 Million Years Ago) Data: The Tetraodontidae are a family of primarily marine and estuarine fish of the order Tetraodontiformes. The family includes many familiar species which are variously called pufferfish, puffers, balloonfish, blowfish, blowies, bubblefish, globefish, swellfish, toadfish, toadies, honey toads, sugar toads, and sea squab. Pufferfishes and porcupinefishes share the order Tetraodontiformes with the triggerfishes, filefishes, boxfishes and their relatives. The tetraodontiforms (or plectognaths) include around 300 species from eight families. Though incredibly diverse, this broad group can be characterized as having modified scales that serve as plates or spines with resultantly restricted gill openings. Kingdom: Animalia Phylum: Chordata Class: Actinopterygii Order: Tetraodontiformes Family: Tetraodontidae-

Chilomycterus (burrfish) mouth plate SITE LOCATION: Pungo River or Yorktown Formation, Aurora, Beaufort Co., North Carolina, USA TIME PERIOD: Miocene age (5.3-23 Million Years Ago) Data: Chilomycterus is a genus of diodontid tetraodontiform fishes commonly called "burrfish." The burrfish resembles the puffer in the positions of its dorsal and anal fins, but its skin is armed with short, stout, triangular spines instead of being merely prickly. These spines are sparsely scattered all over the trunk, with about 9 or 10 from nose to tail along any given line. Furthermore, the burrfish is oval in outline, not fusiform like the puffer; the openings of its nostrils are prolonged in a single tubular tentacle; its bony jaw plates are not divided by a median suture as they are in the puffer, hence each jaw apparently is armed with a single very broad incisor tooth instead of with two; the pectoral fins are not only much larger than in the puffer but their upper edge is level with the upper corner of the gill openings in the burrfish (considerable below it in the puffers); its eye is round, not oval; and its anal fin is below the dorsal, not behind the latter. We need only add that the soft dorsal and anal fins (it has no spiny dorsal) are both rounded, each has 10 to 12 rays; the caudal fin is very narrow and round-tipped; the pectorals are much broader than long, and there are no ventral fins.

Myliobatis sp. dental plates SITE LOCATION: Pungo River or Yorktown Formation, Aurora, Beaufort Co., North Carolina, USA TIME PERIOD: Miocene age (5.3-23 Million Years Ago) Data: Myliobatis is a genus of eagle rays in the family Myliobatidae. Myliobatis species can reach a length of about 150 centimetres (59 in). Body consist of a rhomboidal disc, wider than long, with a one dorsal fin. The head is broad and short, with eyes and spiracles on the sides. The tail is slender, with 1-2 large spines at the base, without tail fin. The teeth are arranged in the lower and upper jaw in flat tooth plates called pavement teeth, each consisting of about 7 series of plates. Said mouth plates are useful to crush clam shells and crustaceans. The extinct species Myliobatis dixoni is known from Tertiary deposits along the Atlantic seaboards of the United States, Brazil, Nigeria, England, and Germany.
