Have you tested a corner of it to see if it's calcite or phosphate? (phosphate won't fizz in HCl). If phosphate, it could be a fish fragment. There were all kinds of weird looking armoured fishes in the Devonian, some probably freshwater; this could be a fragment of one.<br /><br />If it really is a brachiopod fragment and the rocks really are non-marine, then it could be a reworked fragment (river cutting through older marine sediments and redepositing fossil fragments in a non-marine setting).<br /><br />--HowardAnonymousnoreply@blogger.com
