Жили ли черепахи во времена динозавров?
Archelon is an extinct marine turtle from the Late Cretaceous, and is the largest turtle ever to have been documented, with the biggest specimen measuring from head to tail, from flipper to flipper, and in weight. It is known only from the Dakota Pierre Shale and has one species, A. ischyros. In the past, the genus also contained "A. marshii" and "A. copei", though these have been reassigned to "Protostega" and "Microstega" respectively. The genus was named in 1895 by American paleontologist George Reber Wieland based on a skeleton from South Dakota, who placed it into the extinct family Protostegidae. The leatherback sea turtle ("Dermochelys coriacea") was once thought to be its closest living relative, but now, Protostegidae is thought to be a completely separate lineage from any living sea turtle.
