Marginaster is a genus of starfish in the family Poraniidae in the order Valvatida. It was named in 1881 by Edmond Perrier, and the type species is M. pectinatus.[1] In 1995, a fossil brittle star was given the same generic name, but because the name was preoccupied by the starfish, the brittle star had to be renamed.[2] The new name Marginix was given to the brittle star in 2015.[3]
