Devonian Brachiopods

a collection of brachiopods from the Rouge River in southern Michigan. i estimate at least 5 species of species of spiriferid brachiopod are represented in this collection: around two species Mucrospirifer, one species Cyrtina, and two more i plan on looking up this weekend, plus juveniles. the preservation is remarkable for a reworked glacial till deposit.
