Loriolaster was a slow-moving low-level epifaunal detritivore-suspension feeder. Taxonomy from Fossilworks.org. Description from Südkamp 2017, p. 132: " Loriolaster is related to Cheiropteraster and differs by the following features. The smooth skin forms a wide U-shaped area between the arms. The mouth frame consists of the mouth angle plates together with only the enlarged second ambulacrals. Loriolaster has wide ambulacrals and spoon like laterals. Their margin bears three rather short spines as well as one larger spine." Loriolaster gracilis is somewhat rarer than the more robust L. mirabilis. Identified by oilshale. References: W.M. Lehmann. 1957. Die Asterozoen in den Dachschiefern des rheinischen Unterdevons. Abhandlungen des Hessischen Landesamtes für Bodenforschung 21:1-160. Südkamp, W. (2017): Life in the Devonian.
