Cretaceous.
Ecology
Pectinariids are
sessile burrowing tube dwellers, which can be found in fine-grained sediment. They position the wider end of their tube downwards, and use their stout golden
setae for digging while they use tentacles for sorting the particles which they ingest. Half of the particles which the worm digs through are excreted as
pseudofaeces
Pseudofeces or pseudofaeces are a specialized method of expulsion that filter-feeding bivalve mollusks (and filter-feeding gastropod mollusks) use in order to get rid of suspended particles such as particles of grit which cannot be used as food, ...

Genera
The systematics of the pectinariids have been the subject of some debate. Previously, only two genera have been recognized, but three subgenera have been elevated to full genera by some scholars.
