A living taxon that lived through a large portion of [[geologic time]].

The [[Australian lungfish]] (''Neoceratodus fosteri''), also known as the Queensland lungfish, is an example of an organism that meets this criterion. Fossils identical to modern specimens have been dated at over 100{{nbsp}}million years old. Modern Queensland lungfish have existed as a species for almost 30{{nbsp}}million years.<ref>{{Cite web |title=Ann Kemps Lungfish - Queensland - Australia |url=http://annekempslungfish.com.au/lungfish_habitat.html |access-date=2025-01-18 |website=annekempslungfish.com.au}}</ref> The contemporary [[nurse shark]] has existed for more than 112{{nbsp}}million years, making this species one of the oldest, if not actually the oldest extant vertebrate species.
