Distinguishing features: Skeletal bodies are 5-rayed with concavo-convex shape and a sculpted surface
Taxonomy:
These names do appear on taxonomic name lists but not in publications on the algae.
Update - as noted by Ines Galovic (see comments) Dumitrica (1973) and Locker & Martin (1986) provided detailed fossil record data on actiniscids, and described several taxa.
Catalog entries: A. pentasterias [no catalog entry yet]
Distinguishing features: Skeletal bodies are 5-rayed with concavo-convex shape and a sculpted surface
