Artiodactyla
A hoofed mammal who's weight is borne equally by their third and fourth toes, rather than the third toe alone. Mammals like these are pigs, hippos, camels, giraffes, and others. Whales were also part of this group from the common DNA, probably meaning that either in the early Paleogene period or the Cretaceous period whales were once hoofed mammals before the change of climates and the diversities of the mammals. The difference between the even toed hoofed animal and the odd toed hoofed animal is that the even toed had a astragalus which is a ankle joint giving the foot greater flexibility.
The Artiodactyla mainly lived in all the continents except Antarctica and Australia, preferring the warmer climates with lots of vegetation although they were omnivores. These mammals had different intestinal organs since the plant material is harder to digest and also had different teeth to better grind the vegetation they ate.
These mammals are still alive but didn't thrive like the odd toed mammals so thus some of them extinct due to predation.
