Aacocrinus 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][1]

There are currently 14 species within this genus:

  • Aacocrinus acylus (Webster & Jell 1999)[16][17]
  • Aacocrinus algeriaensis (Webster, Maples, Sevastopulo, Frest & Waters 2004)[18][19]
  • Aacocrinus boonensis [20]
  • Aacocrinus chouteauensis[21]
  • Aacocrinus enigmaticus (Webster & Lane 1987)[22]
  • Aacocrinus milleri[23]
  • Aacocrinus nododorsatus (Bowsher 1955)[24][25]
  • Aacocrinus protuberoarmatus (Missouri)[26]
  • Aacocrinus sampsoni[27]
  • Aacocrinus senectus[28]
  • Aacocrinus spinosulus[29]
  • Aacocrinus spinulosus[30]
  • Aacocrinus tetradactylus (Missouri)[31]
  • Aacocrinus triarmatus[32]
