Living Fossils

Triassic Plants and Coelocanth

At any time in the history of life, many plants and animals are persisting, having been around for some time and not on their way to imminent extinction. The Triassic fossils in this case document many such persisters, some of which are still with us as “living fossils.” These include coelacanths, lungfish, horsetails, and freshwater clams in the unionid family.
