Biology:Parilimya

From HandWiki

Parilimya is a genus of marine bivalve molluscs of the family Parilimyidae.[1] Globally distributed, fossils of the genus date back to at least the Miocene.

Description

P. waitotarana

Members of the genus have shells that range from ovate to ovate-elongate, without a sinuous anterior margin. Numerous fine radial ribs is a feature commonly seen in Parilimya.[2]

Taxonomy

The genus was first described in 1899 by James Cosmo Melvill and Robert Standen, as a subgenus of Pholadomya.[3] In 1982, a new family was erected for the genus, Parilimyidae.[4]

Distribution

Members of the genus have been found in the North Atlantic Ocean, the Torres Strait, Japan, the western Pacific Ocean, and New Zealand.[2][5] Fossils of the genus have been found in Japan and New Zealand, dating to the Miocene.[6][5]
