Collagen-eating microbes may explain fossil record gaps

Original: Rise of collagen-eating microbes may help explain gaps in the fossil record

University of Cambridge researchers suggest that the evolution of microbes capable of digesting collagen, the tough protein in animal bones and tissues, may help explain why many ancient organisms left no fossils. As these decomposers spread, they could have destroyed remains before fossilisation, creating apparent gaps in the fossil record and reshaping how scientists interpret missing species.

Why now: The finding offers a novel scientific explanation for a long-standing puzzle in palaeontology.
