Diagnosis
ReferenceDiagnosis
S. F. Mitchell 2013Trace of ligamentary invagination marked by an external groove in primitive forms, but lost in several later derived forms. The posterior myophore of the left valve is rooted on the posterior valve wall and separated from the body cavity by a large endomyophoral cavity formed by a lamina extending from the anterior tooth to the postero-ventral margin. Primitive forms have the anterior tooth much larger than the posterior tooth, but this is lost in some more derived forms
