Thousands of Cambrian fossils discovered in China, new to science
These animal groups lived in the ocean over half a billion years ago but were buried by a subterranean mudflow: Paleontologists found thousands of fossils in rocks on the bank of the Danshui river in Hubei province in southern China, where primitive forms of jellyfish, sponges, algae, anemones, worms and arthropods with thin whip-like feelers were entombed in an ancient underwater mudslide. The creatures are so well preserved in the fossils that the soft tissues of their bodies, including the muscles, guts, eyes, gills, mouths and other openings are all still visible. The 4,351 separate fossils excavated so far represent 101 species, 53 of them new.Ian Sample, “‘Mindblowing’ haul of fossils over 500m years old unearthed in China” at The Read More ›
