lowland tapir


the odd-toed ungulates browsing , grazing mammals. large large, , have relatively simple stomachs , large middle toe. following interchange north america, south america s odd-toed ungulates included equids of genus equus tapirs. equids died out in both north , south america around time of first arrival of humans, while tapirs died out in of north america survived in central , south america. south america once had great diversity of ungulates of native origin, these dwindled after interchange north america, , disappeared entirely following arrival of humans. sequencing of collagen fossils of 1 extinct species each of notoungulates , litopterns has indicated these orders comprise sister group perissodactyls. if, evidence suggests, perissodactyls originated in india, both ungulate groups may have been of gondwanan origin, despite being laurasiatheres.
