Shell morphology, shell texture and species discrimination of Caribbean Tucetona (bivalvia, glycymeridae) From: Journal of Paleontology | Date: May 1, 2001| Author: | Copyright Paleontological Society May 2001. Provided by ProQuest LLC.Copyright information

ABSTRACT-Previous descriptions of Tucetona lack a consistent system using diagnostic characters and only two recent Caribbean 'species' are recognized. In this study, textural and structural features of the Tucetona shell are examined and used as the basis for comparison to other glycymerids and in the recognition of morphospecies. Standard diagnostic characters based mainly on the crosssectional shape of ribs and on hinge teeth ontogeny are presented and used to distinguish six recent Caribbean morphospecies. The shell texture has been examined by light and scanning electron microscopy, ...
