The world鈥檚 oldest known vomit has been discovered in Cambridgeshire. The
fossilised sick probably comes from an ichthyosaur, a marine reptile, which
spewed it up about 160 million years ago. Ichthyosaurs ate shellfish called
belemnites, and the fossil vomit seems to contain indigestible regurgitated
shells. 鈥淭his is the first time the existence of fossil vomit on a grand scale
has been proven,鈥� says Peter Doyle of Greenwich University, whose team found the
fossils in a clay quarry near Peterborough.
