Cylindroleberididae
Template:Short description Template:Automatic taxobox
Cylindroleberididae is a family of ostracods that shows remarkable morphological diversity. The defining feature is the possession of gills: 7–8 leaf-like pairs at the posterior of the body. Other features common to all species in the family include a "baleen-comb" on both the maxilla and the fifth limb, a sword-shaped coxal endite on the mandible, and the triaenid bristles on the basal endites of the mandible.[1]
Species of the Cylindroleberididae are found in marine areas, from shallow waters to depths of more than Script error: No such module "convert"..[2] Most species are approximately Script error: No such module "convert". long. In 2006, there were 219 described species.[3]
A fossil discovered in 2003 with preserved soft parts has been assigned to the Cylindroleberididae.[4] The fossil appears to have gills and is thought to date from 425 million years ago.[4]
