They are among the most iconic and recognizable trilobites in the fossil record due to their distinct,heavy segmented exoskeletons and their tendency to be found beautifully enrolled into defensive balls. \u003cbr\u003eLike all trilobites, their name comes from the three vertical lobes running down the body. One central axial lobe and two side pleural lobes. They typically feature 13 flexible thoracic segments that allow them to roll up like a modern woodlouse to protect their soft bellies from predators. They possess a distinct wide head shield (cephalon) featuring a deeply furrowed central region called glabella. They are relatively small trilobites generally averaging around 2-5cm\u003c\/p\u003e","brand":"Crystal and fossils","offers":[{"title":"Default Title","offer_id":62284820676995,"sku":null,"price":7.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0563\/2524\/3040\/files\/IMG-0208_52791fcc-7ae0-4283-9cbf-791fffe5a42a.heic?v=1785689489","url":"https:\/\/crystalandfossils.co.uk\/products\/calymene-trilobite","provider":"Crystal and fossils","version":"1.0","type":"link"}
