Giant Camels from the Cenozoic of North America

Abstract

Seven genera of giant camels occurred in North America during the interval from the late Clarendonian to the early Holocene. <i>Aepycamelus</i> was the first camel to achieve giant size and is the only one not in the subfamily Camelinae. <i>Blancocamelus</i> and <i>Camelops</i> are in the tribe Lamini, and the remaining giant camels <i>Megatylopus, Titanotylopus, Megacamelus, Gigantocamelus</i>, and <i>Camelus</i> are in the tribe Camelini. <i>Megacamelus</i> is a late Hemphillian giant camel most closely related to <i>Gigantocamelus. Titanotylopus</i> is reserved for the brachyodont form from the Irvingtonian of Nebraska, and <i>Gigantocamelus</i> is reinstated for the broad-chinned, Blancan form.
