Oldest vomit
United Kingdom (Greenwich University)

On 12 February 2002, a team of palaeontologists, led by Prof. Peter Doyle (Greenwich University, UK) announced their discovery of the fossilised vomit of an ichthyosaur, a large, fish-like marine reptile. Discovered in a quarry in Peterborough, the 160 million-year-old vomit could provide an insight to the feeding habits of ichthyosaurs. The arrangement of belemnite shells in the vomit suggest that the reptiles may have eaten the shelled creatures whole, and then regurgitated the shells, much in the same way an owl eats a mouse.
