So a very strange archaeo find in england... a mass frog grave in association with a village and  house.  could this be the origin of the "diamonds and toads" fairy story?   Evidence of a strange Cuthulian rite, or maybe just a fondness for frog soup? prolly not.  perhaps the townsfolks were just over-run with frogs as sometimes happens in froggy habitats...
