Aacocrinus, also known as the feather star, is a genus of extinct sea lily from the Actinocrinitidae (or Patelliocrinidae) family.[4][5][6][7][8][9][10][11][12][13] It has been shown that it was an attached stationary organism that blindly fed on passing organism. It was composed of Mg calcite and its habitat included the upper-level epifauna.[14][15][16]
There are currently 14 species within this genus:
- Aacocrinus acylus (Webster & Jell 1999)[17][18]
- Aacocrinus algeriaensis (Webster, Maples, Sevastopulo, Frest & Waters 2004)[19][20]
- Aacocrinus boonensis [21]
- Aacocrinus chouteauensis[22]
- Aacocrinus enigmaticus (Webster & Lane 1987)[23]
- Aacocrinus milleri[24]
- Aacocrinus nododorsatus (Bowsher 1955)[25][26]
- Aacocrinus protuberoarmatus (Missouri)[27]
- Aacocrinus sampsoni[28]
- Aacocrinus senectus[29]
- Aacocrinus spinosulus[30]
- Aacocrinus spinulosus[31]
- Aacocrinus tetradactylus (Missouri)[32]
- Aacocrinus triarmatus[33]
