An isolated and deformed lower tooth plate of an eagle ray (Aetomylaeus sp., Myliobatidae, Myliobatiformes) is reported herein from the Miocene deposits along Calvert Cliffs, Maryland, U.S.A. Deformed myliobatid tooth plates like this, either fossil

Fossil dolphins belonging to the extinct family Kentriodontidae are small to medium-sized toothed cetaceans, which probably include the ancestors of some living species. Kentriodontids are known from rocks of Late Oligocene to Late Miocene age in var

The use of skeletal oxygen isotopic records for use in paleotemperature reconstruction has been hampered by the lack of independent evidence for ocean water oxygen isotopic composition. The δ18O record from homeothermic cetaceans has provided an ind

δ 18 O analyses of phosphate in cetacean bones, presumably precipitated at body temperatures of 36-37°C, offer a potential means of determining the isotopic composition of Tertiary seas. Isotopic analyses of Recent marine cetaceans suggest that the

When Ogygoptynx wetmorei was reported by Rich & Bohaska (1976), it appeared to represent a unique and new avian group. Detailed comparisons of this Early Paleocene form from Colorado (USA) have clearly demonstrated that it is distinct from North Amer
