This evolutionary milestone coincided with the great Ordovician biodiversification event,a time when global sea levels peaked,tropical water temperatures thrived and marine life expanded dramatically,\u003cbr\u003eDuring the Ordovician period,brittle stars formally split from true starfish (Asteroidea). While true starfish developed wider,hollow arms integrated into their body structure,ancient ophiuroids evolved a highly distinct anatomy.\u003cbr\u003eBrittle starfish skeleton consists of fragile,loosely embedded calcareous plates (ossicles),their bodies typically disintegrate rapidly after death.\u003cbr\u003eSudden underwater storms or dense microbial mats rapidly buried the creatures in anoxic (oxygen-depleted) mud,preventing decomposition and capturing their delicate dancing arm positions in spectacular detail.\u003c\/p\u003e","brand":"Crystal and fossils","offers":[{"title":"Default Title","offer_id":62696855863683,"sku":null,"price":75.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0563\/2524\/3040\/files\/IMG-1311_3024cae2-bd7a-465f-aa24-74f48e33125e.heic?v=1790271039","url":"https:\/\/crystalandfossils.co.uk\/products\/brittle-starfish-ophuroides-3","provider":"Crystal and fossils","version":"1.0","type":"link"}
