    "abstract": "Fossil remains of 22 kinds of Paleogene turtles have been recovered in Maryland and Virginia from the early Paleocene Brightseat Formation (four taxa), late Paleocene Aquia Formation (nine taxa), early Eocene Nanjemoy Formation (five taxa), middle Eocene Piney Point Formation (one taxon), and mid-Oligocene Old Church Formation (three taxa). Twelve taxa are clearly marine forms, of which ten are pancheloniids (\nAshleychelys palmeri\n, \nCarolinochelys wilsoni\n, \nCatapleura coatesi\n, \nCatapleura\n sp., \nEuclastes roundsi\n, \nE. wielandi\n, ?\nLophochelys\n sp., \nProcolpochelys charlestonensis\n, \nPuppigerus camperi\n, and \nTasbacka ruhoffi\n), and two are dermochelyids (\nEosphargis insularis\n and cf. \nEosphargis gigas\n). Eight taxa represent fluvial or terrestrial forms (\nAdocus\n sp., \nJudithemys kranzi\n n. sp., \nPlanetochelys savoiei\n, cf. \n“Trionyx” halophilus\n, \n“Trionyx” pennatus\n, “Kinosternoid B,” Bothremydinae gen. et sp. indet., and Bothremydidae gen. et sp. indet.), and two taxa (\nAspideretoides virginianus\n and \nAllaeochelys\n sp.) are trionychian turtles that probably frequented estuarine and nearshore marine environments. In Maryland and Virginia, turtle diversity superficially appears to decline throughout the Paleogene, but this probably is due to an upward bias in the local stratigraphic column toward more open marine environments that have preserved very few remains of riverine or terrestrial turtles.",
