These ripples may be the earliest evidence of muscle tissue ever found. The 560 million-year-old fossil was found on Newfoundland\u2019s Bonavista Peninsula and were left behind by an organism named Haootia quadriformis, an ancient relative of jellyfish. (Photo credit: Alexander Liu)<\/p><\/div>\n

The fossil comes from a time known as the Ediacaran period, renowned for its preservation of the first large and complex organisms known. Most Ediacaran organisms were flat, sheet-like, or frond-like creatures whose relationships to modern organisms are hard to pin down.\u00a0<\/span><\/p>\n

This particular fossil organism, <\/span>Haootia quadriformis<\/span>, contains symmetrical fibrous structures that the authors interpret as muscle tissue. The authors suggest that <\/span>H. quadriformis<\/span> could be an early member of <\/span>Cnidaria<\/span>, a group whose living members include jellyfish and sea anemones.<\/span><\/p>\n
