Description: Tullimonstrum, AKA the Tully Monster may be the greatest mystery in the history of paleontology! At various times, this enigmatic animal, which lived about 300 million years ago, has been reconstructed as a fish, an arthropod, a mollusk, a worm, and more... and its true identity is still a subject for debate among paleontologists!
Description: The variation on Leonardo Da-Vinci's Vitruvian Man depicts a choanoflagellate "rosette" colony. Choanoflagellates are thought to be the unicellular organisms (protozoans).that are most closely related to the animals, and so they seem strangely appropriate to this renaissance classic!
Description: This Illustration shows two views of the impressive skull of the famous paleo-cetacean, Dorudon. Dorudon, (or some closely related animal) which swan the seas some 30-40 million years ago is thought to be ancestral to all modern whales and dolphins, including both the toothed-whales (odontoceti) and the baleen whales (mysticeti).
