Abstract

Three specimens of a Late Mississippian pseudopunctate brachiopod, Orthotetes kaskaskiensis (McChesney), exhibit a rare, though altered, color pattern. The alternating, concentric white and gray banded pattern parallels the growth laminae. These rare color bands are interpreted as the reverse of the original pigmented bands. That is, the present light areas represent the originally darker, more pigmented bands. A high qualitative correlation between heavily pigmented color bands and growth increments, which are present in regular circumferential bands, indicates that the shell growth of some brachiopods is periodic.
