Resumen

Los vertebrados que habitaron el norte de América del Sur pocos millones de años después del evento Cretácico-Paleógeno (K-Pg) aún son poco conocidos. Aquí presento restos de tortugas y crocodilomorfos del Paleoceno inferior al medio, Formación Lisama de Colombia; que representa el primer registro de vertebrados del Paleoceno para la Cuenca del Valle del Magdalena Medio, y una de las faunas más tempranas del Paleoceno del norte de América del Sur. Aunque es imposible establecer una paleontología sistemática detallada debido a su preservación fragmentaria, demuestro que las células óseas (osteocitos) se conservan en algunos de estos fragmentos.

N2 - Vertebrates that inhabited northern South America few million years after the Cretaceous-Paleogene (K-Pg) event are still poorly known. Here I present remains of turtles and crocodylomorphs from the lower to middle Paleocene, Lisama Formation of Colombia; representing the first record of Paleocene vertebrates for the Middle Magdalena Valley Basin, and one of the earliest Paleocene northern South American faunas. Although it is impossible to establish detailed systematic paleontology due to their fragmentary preservation, I demonstrate that bone cells (osteocytes) are preserved in some of these fragments.
