The fossil displays the characteristic coiled shell of a Devonian ammonoid, with visible whorls preserved in relief against the surrounding matrix. Specimens such as this represent marine cephalopods that inhabited the ancient seas covering the Holy Cross Mountains approximately 370 million years ago.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eThe Kowala section situated in the southern part of the Holy Cross Mountains represents continuous sedimentation in almost the same facies across the Devonian-Carboniferous transition. Fossils occur in black, pyritic shales, gray calcareous shales, clayey marls and light gray biohermal limestones. In most cases fossils are preserved as totally flattened imprints, sometimes tectonically deformed. However, in some lenses perfect, pyritized molds of gastropods, goniatites, bivalvias, clymenias were found. This part of the profile represents lower Famennian.\u003c\/p\u003e\n\u003cp\u003eAlthough dinosaurs are the most well-known fossil life forms, pyritized fossils are also a favorite among those familiar with Paleontology (the study of the development of life on Earth) and are found in the rocks of all continents.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan\u003eName:\u003c\/span\u003e\u003c\/strong\u003e Goniatite Fossil\u003cbr\u003e\u003cstrong\u003e\u003cspan\u003eAge: \u003c\/span\u003e\u003c\/strong\u003eFammenian (Devonian)\u003cbr\u003e\u003cstrong\u003e\u003cspan\u003eLocation: \u003c\/span\u003e\u003c\/strong\u003eKowala Formation, Poland\u003cbr\u003e\u003cspan\u003e\u003cstrong\u003eGeological unit:\u003c\/strong\u003e Kielce-Lagow Syncline\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003cspan\u003e\u003cstrong\u003eSize:\u003c\/strong\u003e max matrix: 83x34 mm, max fossil:  16 mm \/ approx. 47.6 gr \u003c\/span\u003e\u003c\/p\u003e","brand":"Canagem.com","offers":[{"title":"Default Title","offer_id":71853087228157,"sku":"03-00061","price":33.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0053\/3309\/0374\/files\/20261109_133837.jpg?v=1794251128","url":"https:\/\/canagem.com\/products\/goniatite-embedded-in-shale-fossil-natural-fossilized-pyritized-in-host-rock-fammenian-devonian-kowala-formation-poland","provider":"Canagem.com","version":"1.0","type":"link"}
