Moropus (meaning "slow foot") [2] is an extinct genus of large perissodactyl mammal in the chalicothere family. They were endemic to North America during the Miocene from ~20.4–13.6 Mya, existing for approximately

Moropus, extinct genus of the chalicotheres, a group of very unusual perissodactyls (“odd-toed” ungulates) related to the horse. Fossil remains of Moropus are found in Miocene deposits in North America and Asia (the Miocene Epoch lasted from 23.7 to …

最著名的裂爪獸亞科當屬 石爪獸屬 （ 英语 ： Moropus ） ，而最後存活的演化支傳統上認為是奈王爪獸屬 [3] ，但實際上奈王爪獸屬應是屬於爪獸亞科 [4] 。

爪獸科不像現今的奇蹄目，是有長的前肢及短的後肢，故牠們可能主要以其後肢來支撐身體。 牠們的前肢有長及彎曲的爪，故牠們可能和現存的大食蟻獸一樣是趾行的。 化石遺骸亦有發現厚及發展良好的前趾關節，很像現今的大猩猩。 牠們的爪曾一度被認為是用來挖掘樹根及塊莖，但爪及牙齒 …

Moropus is a well-known chalicothere from the early Miocene of North America. Its bodily proportions are similar to a living okapi (a kind of short-necked giraffe), with longer forelimbs than hindlimbs and a somewhat elongated neck.

Moropus is a chalicothere, an herbivore closely related to horses and rhinos. Chalicotheres are noted for their deep skulls and heavy, sloping builds, almost like that of a gorilla. They have long arms tipped with claws instead of hooves, and some of them knuckle-walk. Moropus doesn't; instead it has a weird "pigeon-toed" gait.

化石产于北美和亚洲的中新统。像现代马一样大，但和其他奇蹄类不一样，有爪而没有蹄。前肢比后肢长，自前背部向臀腰部 ...
