Resumen

Describimos el primer fósil indiscutible de Rhinoclemmys (Cryptodira, Geoemydidae) al este de los Andes, representado por un hueso nucal aislado que se encuentra en uno de los sitios paleontológicos más importantes con asociación de fauna y humanos (sitio de Muaco, Venezuela occidental) del Pleistoceno tardío del sur del caribe. La nuca es completa y ligeramente más ancha (4,8 cm) que larga (4,2 cm), conservando surcos bien definidos de cervical, vertebral 1, marginal 1 y pleural 1. Las comparaciones con especímenes fósiles y existentes de Rhinoclemmys nos permiten atribuir esto Nucal a Rhinoclemmys, aunque como una especie indeterminada. La ocurrencia de Rhinoclemmys en el sur de la península de Paraguaná indica que durante el Pleistoceno tardío esta región tenía condiciones ambientales que permitieron la supervivencia de estos reptiles de agua dulce y terrestre, en particular de "paleo manantiales" dentro de una región semiárida
