There were a lot of odd-toed ungulate animals in the ancient times but now just few of them survived. What is the reason for that?

  • $\begingroup$ I edited the question somewhat. You need to provide some more details such as how many/what fraction of odd-toed ungulates got extinct. Compare it with other group such as even-toes ungulates. Because a lot of species perish during selection event. When saying a lot of group-A organisms perished you should mention with respect to what? $\endgroup$ – WYSIWYG Nov 19 '14 at 5:43

there are two suborder under perissodactyla that are still suvival, Hippomorpha and Ceratomorpha. many perissodactyla species become extinct may bacause the member of perissodactyla animals have sample stomach, compared with artiodactyla, so after the plant change on the earth, they cannot adapt it. and also hinting was one part of reason. http://en.wikipedia.org/wiki/Odd-toed_ungulate
