Horsetail plants are considered living fossils, as they have gone through little to no evolutionary change for their entire existence. Horsetails can be found nearly everywhere in the world, excluding most of Oceania and all of Antarctica. They first appeared in the early Jurassic period, around 200 million years ago.
