The Marshalls Creek Mastodon recently completed a stint as the centerpiece in the Tusks! exhibition that traveled throughout the United States. The 'Ice Age Mammoths & Mastodons' exhibition displayed prehistoric animals that roamed North America until the end of the last Ice Age.
The end of Tusks! doesn't mean that the mastodon bones will be packed into a box and shelved. [as happened previously] The mastodon has now been reassembled in its permanent location at the State Museum of Pennsylvania, in the new paleontology gallery.
'Life Through Time: A New Paleontology Experience,' documents environmental changes spanning 296 million years, and features Phytosaurs, which resemble modern crocodiles, the Parasaurolophus, a dinosaur known for its ornamental cranial crest, and a Platybeladon, which is related to the elephants of today.
