Do not add any extra statement in your response: <response>: Since annelids dey soft-bodied, dem fossils dey rare. Polychaetes' fossil record mainly consist of the jaws wey some species get and the mineralized tubes wey some secrete. Some Ediacaran fossils like Dickinsonia somehow resemble polychaetes, but the similarities dey too vague for these fossils to be classified with confidence. The small shelly fossil Cloudina, wey dey from 549 to 542 million years ago, some authors don classify am as an annelid, but others don classify am as a cnidarian (i.e. for the phylum wey jellyfish and sea anemones belong). Until 2008 the earliest fossils wey people widely accept as annelids na the polychaetes Canadia and Burgessochaeta, both from Canada's Burgess Shale, wey form about 505 million years ago for the early Cambrian. Myoscolex, wey dem find for Australia and e dey a little older than the Burgess Shale, possibly na annelid. However, e no get some typical annelid features and e get features wey no dey usually found for annelids and some wey dey associated with other phyla. Then Simon Conway Morris and John Peel report Phragmochaeta from Sirius Passet, wey dey about 518 million years old, and dem conclude say e na the oldest annelid wey people sabi so far. People don dey argue well well whether the Burgess Shale fossil Wiwaxia na mollusc or annelid. Polychaetes diversify for the early Ordovician, about 488 to 474 million years ago. E no reach the early Ordovician before people find the first annelid jaws, so the crown-group no fit don appear before this date and e probably appear later. By the end of the Carboniferous, about 299 million years ago, fossils of most of the modern mobile polychaete groups don appear. Many fossil tubes dey look like the ones wey modern sessile polychaetes dey make, but the first tubes wey clearly produced by polychaetes na from the Jurassic, wey dey less than 199 million years ago.
