Who knows what species might rise from the grave next? Here are a few who have already pulled off this fantastic feat. Still, those animals that are no longer extinct give us some hope for the future. For the sake of this article, let’s apply this concept to the subject of extinction. As a starting point for this musing, I hope readers will agree that many facets and phenomena of life and our experience on earth occur on a spectrum. In the wild, it mainly lives in Costa Rica (the image seen here is from a frog farm in Colombia), where it was rediscovered in 2003. The Ivory-billed Woodpecker and the Spectrum of Extinction. Certain species, such as the Javan Elephant, have gone from extinct to rediscovered and back again several times over.

This frog species is critically endangered. 13 Ornithologists currently recognize two subspecies of this bird: American ivory-billed woodpecker ( C. And while the concept of these creatures might be exciting, it's also a little bit concerning as the vast majority of them are still highly endangered. Lazarus lizards are found in murals, on carousels, and the original neighborhood they were introduced to is often unofficially marked on maps as Lizard Hill in their honor. The genus Campephilus was introduced by the English zoologist George Robert Gray in 1840 with the ivory-billed woodpecker as the type species. These animals are often referred to as "Lazarus species," because of the way they seem to rise from the dead. Several of these species have even lived for millions of years without being rediscovered. In this last case, the term Lazarus taxon is applied in neontology. But perhaps most miraculous of all is when we find that animals that were thought to be extinct are somehow still alive! It's not that these species were somehow revived from extinction - rather, many of them have hidden away, often right under our noses, continuing to live after when we had assumed they were long gone. Finally, the term 'Lazarus species' is applied to organisms that have been rediscovered as being still alive after having been widely considered extinct for years, without ever having appeared in the fossil record. By that same line of thought, though, it's absolutely thrilling when a new species is discovered. It's always sad when an animal species goes extinct and suddenly disappears from our world.
