The Mesozoic Era (pronunciation: /ˌmɛsəˈzɪk, ˌm-, -s-/ or /ˌmɛzəˈzɪk, ˌm-, -z-/) is an interval of geological time from about 252 to 66 million years ago. It is also called the Age of Reptiles, a phrase introduced by the 19th century paleontologist Gideon Mantell who viewed it as dominated by reptiles such as Iguanodon, Megalosaurus, Plesiosaurus and what are now called Pseudosuchia.
