"A new fossil discovery identifies the earliest evidence for animals with muscles. An unusual new fossil discovery of one of the earliest animals on earth may also provide the oldest evidence of muscle tissue -- the bundles of cells that make movement in animals possible.

The fossil, dating from 560 million years ago, was discovered in Newfoundland, Canada. On the basis of its four-fold symmetry, morphological characteristics, and what appear to be some of the earliest impressions of muscular tissue, researchers from the University of Cambridge, in collaboration with the University of Oxford and the Memorial University of Newfoundland, have interpreted it as a cnidarian: the group which contains modern animals such as corals, sea anemones and jellyfish. The results are published today (27 August) in the journal Proceedings of the Royal Society B.
