Extract
The Heteractinida are a relatively minor group of calcareous sponges, although Astraeospongium, one of the currently 14 known genera in the order, is one of the most commonly studied fossil sponges in the world. Principle record of the Heteractinida is from North America and Europe, although they have now been reported from Australia, Africa, Asia and South America. Occurrences in the latter areas generally are only isolated spicules or single specimens.
