Analysis of the charred bones of a small animal unearthed by archaeologists digging about a mile away from Stonehenge in England confirmed they were toad bones from legs that had been cooked and eaten, The Guardian reported Tuesday.
The bones, from a Mesolithic site thought to be the oldest continuous settlement in Britain, have been dated to between 7596 B.C. and 6250 B.C.
"We were completely taken aback," team leader David Jaques said, noting evidence suggests the Mesolithic people had a varied diet.
"We can see people eating huge pieces of aurochs, cows which are three times the size of a normal cow, and we've got wild boar, red deer and hazelnuts."
"There were really rich food resources for people and they were eating everything that moved, but we weren't expecting frogs' legs as a starter," he said.
The findings at the dig site suggest the area provided different types of food resources to keep people going all year round, including the tasty frogs, he said.
"Frogs' legs are full of protein and very quick to cook: the Mesolithic equivalent of fast food," he said.
