Their fossils are commonly found in the Carbondale Formation of Illinois, USA. \u003c\/p\u003e\n\u003cp\u003eDiplazites unita belongs to the class Filicopsida, which includes ferns. It's a member of the extinct order Marattiales, which grew as tree ferns.\u003cbr\u003eThe fern had pinnate leaves with specific vein patterns and sporangia on the underside. Mature pinnules are separate and broadly attached to the rachis, with a strong midvein extending nearly to the apex. These ferns likely grew in swampy areas, rapidly occupying disturbed soil away from flooded habitats. They could reach heights of up to 30 feet, with trunks covered in a wide, fibrous root mantle.\u003c\/p\u003e","brand":"In Stone Fossils","offers":[{"title":"Default Title","offer_id":49140532478174,"sku":"ILFRN6","price":55.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0466\/5117\/9163\/files\/rn-image_picker_lib_temp_fbc24cd8-0c64-4777-b380-ac00f4eaa16e.jpg?v=1792773516","url":"https:\/\/instonefossils.com\/products\/fossil-fern-diplazites-unita-illinois-2","provider":"In Stone Fossils ","version":"1.0","type":"link"}
