 However, art of extinct animals has existed long before Henry De la Beche's 1830 painting "Duria Antiquior", which is sometimes credited as the first true paleontological artwork.These older works include sketches, paintings and detailed anatomical restorations, though the relation of these works to observed fossil material is mostly speculative.For example, a Corinthian vase painted sometime between 560 and 540 BCE is thought by some researchers to bear a depiction of an observed fossil skull.
