Contenido principal del artículo
Resumen
Se describen los restos óseos de un camélido procedentes del arroyo La Muela, Baja California Sur, México. Con base en los datos merísticos y a la fórmula dental aquí descrita, el ejemplar fue asignado a Camelops hesternus, especie ampliamente distribuida en Norteamérica durante el Pleistoceno. Además, las comparaciones realizadas con el espécimen descrito por Webb (1965) en La Brea Tar Pits (California) del pozo de alquitrán no muestran diferencias morfológicas significativas, sugiriendo una comunidad faunística alguna vez continua en Norteamérica, extendida hasta el sur de la península de Baja California.
