The annelids or so called “ringed worms” form a phylum within the kingdom Animalia. Some examples of recent annelids are earthworms and bristle worms or Polychaeta. Member of the latter group are the Serpulidae, sometimes called tube worms. Tube worms are named after the calcium carbonate tubes they secrete, which are frequently found as fossils.

Fossils of soft bodied annelids  are known from several Lägerstatten, from these fossil records we know it was a thriving group even as early as the Cambrian Period.
