Fissure Islands and Sphenosuchid, Triassic England, Doug Henderson, 2003

Once, Wales sat at the latitude of the Sahara, but instead of a desert, those coordinates were flooded by an ichthyosaur-laden sea. Even in the Triassic, Britain was islands. Gracile crocodiles scampered along its sea-sprayed rocks and danced inside early conifer forests. They were lithe things made of mostly legs—reptiles that had become greyhounds, sphenosuchian-salukis who tiptoed on their hindquarters, among the first to earn the title biped.
