Mysella is a genus of marine bivalve molluscs of the family Lasaeidae.[1]
Description
[edit]Shells of Mysella are thin and concentrically striated.[2] Shells range from small to moderately sized, are inequilateral, and has a produced anterior end.[3] The hinge has a small triangular internal cartilage pit.[2] Members of the genus have a narrow hinge line, a short resilium, and right valves that either have a single oblique anterior tooth, or both an anterior and posterior tooth; the latter being much weaker if present, except in species which are relatively more equilateral.[3] Mysella have limited external sculpture, and are most commonly under 5 mm (0.20 in) in size, with some species reaching a length of 10 mm (0.39 in).[4]
Taxonomy
[edit]The genus was first described in 1877 by George French Angas.[2]
Distribution
[edit]Mysella has a global distribution.[5] The earliest known fossils of the genus date to the Paleocene, and have been found in Alabama and Texas in the United States.[6]
