The bones of a dinosaur were found near Bristol during the 1970s
More than 1,000 fossil hunters are descending on Bristol for an international conference this week.
It is the first time the Society of Vertebrate Palaeontology will hold its annual meeting outside North America.
The four day conference will see evidence of feathered dinosaurs, ancient giraffes, and bison from the bottom of the North Sea.
Prof Mike Benton, chairman of the host committee, said: "This will be a momentous meeting for the society."
