Dear Guys,
This summer I found these two fossils in the same fluvial sandstone erratic boulder- the first is possible procoracoid bone of Pelycosaur (the specialist thinks it belongs to reptile or reptiliomorph amphibian), and the second is glossy skull bone of sarcopterygian fish (probably lungfish but also could belong to megalichthyid). The procoracoid bone is 1.4 cm length and the skull bone of fish is 5 mm length. The erratic boulder was found in Dauksiai village, Joniskis district, Northern Lithuania.
Please help me to know which kind of fish this skull bone belongs to.
Any help will be appreciated!
Best Regards
Domas
