摘要: RESUMEN Describimos restos craneales fragmentarios de ictiosaurio pertenecientes a un unico individuo, recuperado desde estratos marinos del Jurasico Inferior norte Chile. Los dientes preservados muestran caracteristicas distintivas, como una raiz muy larga, robusta y con gruesos pliegues, asi tambien coronas bajas, triangulares, masivas, labio-lingualmente comprimidas carenas. Las dentales son consistentes las genero Temnodontosaurus, anteriormente conocido en el Europa. Este descubrimiento representa primer registro temnodontosaurido hemisferio sur, reforzando patron intercambio faunistico entre Tetis Panthalassa antes la separacion Laurasia Gondwana, establecimiento completo via maritima Caribe.
