2. Camels

Did you know that camels once lived in North America? Referred to as Camelops, prehistoric camels were more akin to llamas than the camels we know today. Around 45 million years ago, camels started showing up in North America, during the Eocene period. It’s hard to tell if prehistoric camels had humps like modern species, but experts believe they most likely have two humps.

Plant remains have been found in the teeth of camels, leading researchers to conclude that they were the type of species that ate a variety of plants. They frequently ate coarse shrubs found on the coast of Southern California. It’s believed that these camels could not go for extended periods without water. That adaptation may have started to evolve once camels migrated to Africa and Asia. Prehistoric camels were roughly 7 feet tall and weighed nearly a ton.
