|Distribution||Eocene of Hungary|
|Type||Titanaster labiostoma Szorenyi, 1929, by original definition.|
|Species Included||Only the type species.|
|Classification and/or Status||Irregularia, Atelostomata, Holasteroida
|Remarks||The original description of this genus is in the dissertation of E. Szorenyi, which does not count as a valid publication. Mortensen (1950, p. 84) in publishing the name and illustration validated the genus. Without knowledge of the oral plating it is impossible to place this genus beyond Holasteroida.
