Hulking in our Morian Hall of Paleontology, Wyrex is one of the most unique Tyrannosaurs Rexes ever unearthed. His feet are more complete than any other specimen to date. He has the remnant of a third finger digit, something that's only been found once before. We even have pieces of his skin! But it's his tail — or rather, what's missing from it — that holds the greatest mystery.
