Specimens ranging from embryonic size (about 0.7 inches) to full-grown adults (about 26 inches) are common. Smaller-sized specimens are more commonly found in mid-lake than near-shore deposits. This suggests that D. dentatus spawned in open water.\u003c\/p\u003e\n\u003cp\u003eThis species' upturned mouth indicates it fed at the surface of Fossil Lake. D. dentatus specimens are commonly found with other fish stuck in their mouths, including other D. dentatus specimens.\u003c\/p\u003e","brand":"In Stone Fossils","offers":[{"title":"Default Title","offer_id":48401104077022,"sku":"DIPLO92","price":45.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0466\/5117\/9163\/files\/rn-image_picker_lib_temp_0b43b12f-6361-4ac4-ad92-395893766413.jpg?v=1783634965","url":"https:\/\/instonefossils.com\/products\/2-25-2-5-diplomystus-dentatus-green-river-formation-wyoming-1","provider":"In Stone Fossils ","version":"1.0","type":"link"}
