Glomerula

Glomerula is a genus of polychaete worm in the family Sabellidae. It differs from all other Sabellidae in having a calcareous tube and spinose setae. Only one living species, G. piloseta, is known from Lizard Island, Great Barrier Reef, Australia. [2] The oldest fossils of Glomerula are known from the Early Jurassic[1] and their tube microstructure has remained unchanged since then.[3]

Not to be confused with Glomerulus.
