Mass frog burial baffles experts at iron age site near Cambridge An unprecedented trove of 8,000 bones presents archaeologists at a road dig with a prehistoric mystery.
Archaeologists working near the site of an iron age home near Cambridge were perplexed when they uncovered a vast trove of frog skeletons. Quite why more than 8,000 bones had been piled up and preserved is a prehistoric mystery.
