Please join the Smithsonian Associates in welcoming Mark P. Witton, author of King Tyrant. In his new book, King Tyrant: A Natural History of Tyrannosaurus rex, Witton surveys what we鈥檝e learned about the 鈥淜ing of the Tyrant Lizards鈥� since it was first given its famous name in 1905. He examines these creatures as science knows them rather than the version portrayed in movies, revealing them to be dramatically different and more amazing than imagined.
