The Ed Leith Cretaceous Menagerie is a museum in Winnipeg, Manitoba, Canada. The museum is housed in the atrium area of the Wallace Building at the University of Manitoba. It is educational, interactive and publicly accessible. The menagerie features complete skeletal replicas of four creatures. Three of the specimens are marine: a gigantic, vicious fish, the world's largest sea turtle and an enormous, formidable mosasaur ('sea lizard'). Finally, an aggressive tyrannosauriddinosaur represents the land creatures.
