Cheirothyris

Cheirothyris is a genus of fossil brachiopod from the Upper Jurassic period. The shells of this genus are characterised by four, high, radially arranged ribs on each valve. On the anterior edge of the valves the ribs protrude like fingers, so that the shells look like the webbed feet of birds from above.〔Ivanov, Hrdlickova & Gregorova (2001) The Complete Encyclopedia of Fossils: A Comprehensive guide to Fossils from around the world Rebo Publishers, , The Nederlands. pp. 312 ISBN 90-366-1500-3〕 ''Cheirothyris fleuriausa'' is one of the largest reported specimens measuring about 3 cm.
