Resumen

El registro fósil global de los pterosaurios del Cretácico inferior es escaso y gran parte del material es fragmentario. Aquí reportamos tres ocurrencias de pterosaurios de la Formación Rosablanca (Valanginiano), los primeros registros de este grupo extinto de reptiles voladores de Colombia. Los especímenes de Zapatoca, Departamento de Santander, consisten en fragmentos de la mandíbula izquierda y la porción proximal de una falange del ala. Un tercer espécimen, del departamento de Cundinamarca, es la terminación proximal de un radio. Aunque fragmentarios, estos restos son claramente pterosaurianos, debido a sus paredes óseas notablemente delgadas y proporcionan evidencia de pterodactiloides, incluido un gran ornitocheiroide no pterosauriano, en la parte más septentrional de América del Sur en el Cretácico más bajo.
