Tylopoda
Sign in to saveTylopoda (meaning "calloused foot") is a suborder of terrestrial herbivorous even-toed ungulates belonging to the order Artiodactyla. They are found in the wild in their native ranges of South America, Africa, and Asia, while Australian feral camels are introduced. The group has a long fossil history in North America and Eurasia. Tylopoda appeared during the Eocene around 50 million years ago.

胼足亚目（学名：Tylopoda）是偶蹄目的一个演化支，大约在4620万年前始新世中期开始出现，在北美洲及欧洲都有长期的化石记录，现在仅有骆驼科一支存活至今，目前分布在南美洲、亚洲及非洲北部；澳洲大陆也有由人类引进的野化骆驼分布。 胼足动物曾经非常多样化，比如原角鹿科、无防兽科、双锥齿兽科、剑齿兽科等都被归类于此亚目，高齿羊类的岳齿兽科及Agriochoeridae也包含在其中。 分类 本亚目是偶蹄目的基群，也就是最早与其它偶蹄目动物分开演化的，是所有现生偶蹄类的共同旁系群，其它偶蹄类可以组成单系群全撰类，其关系如下[1]： 偶蹄目 Artiodactyla 全撰类 Artiofabula 鲸反刍类 Cetruminantia 河马形亚目 Whippomorpha 鲸下目 Cetacea 须鲸小目 Mysticeti 齿鲸小目 Odontoceti 凹齿下目 Ancodonta 反刍亚目 Ruminantia 有角下目 Pecora 鼷鹿下目 Tragulina 猪形亚目 Suina 胼足亚目 Tylopoda 图集 奇角鹿 高齿羊 无防兽 新兽的头颅骨 四角鹿 羊驼 参考文献 ^ Spaulding, M., O'Leary, M.A. & Gatesy, J.

Tylopoda (meaning "calloused foot") is a suborder of terrestrial herbivorous even-toed ungulates belonging to the order Artiodactyla. They are found in the wild in their native ranges of South America, Africa, and Asia, while Australian feral camels are introduced. The group has a long fossil history in North America and Eurasia. Tylopoda appeared during the Eocene around 50 million years ago.
Tylopoda has only one extant family, Camelidae, which includes camels, llamas, guanacos, alpacas and vicuñas. This group was much more diverse in the past, containing a number of extinct families in addition to the ancestors of living camelids (see below).
