Pleuromeris finlayi is an extinct species of marine bivalve mollusc in the family Carditidae. Fossils of the species date to the Late Pliocene, Pleistocene and recent strata in New Zealand.
Description
In the original description, Powell described the species as follows:
The holotype of the species has a height of , length of and a single valve thickness of . It can be differentiated from P. zelandica due to having more numerous radials (17 vs. 14), more oblique, having a broader median cardinal for the right valve and a narrower median cardinal on the left, and due to the shell being thinner.
Taxonomy
The species was first described by A.W.B. Powell in 1938. The holotype was collected at a date prior to 1939 from Napier Port, Napier, New Zealand, and is held by the Auckland War Memorial Museum.
Distribution
This extinct marine species occurs between Late Pliocene (Mangapanian stage) and recent strata of New Zealand, dating back to three million years before the present. Fossils have been found near Napier, and the South Taranaki Bight coast (Waitōtara, Nukumaru).
