Abstract The earliest endosymbiotic tubeworms have been discovered within skeletons of the tabulate coral Heliolites sp. from the Silurian (Ludlow) of Podolia, Ukraine. The new tubeworm species has a maximum diameter about 1 mm, a slightly conical tube, a smooth lumen in the tube and a lamellar wall structure. The tube wall is 0.05–0.10 mm thick. The new endosymbiotic tubeworm Coralloconchus bragensis n. gen. and sp. shares zoological affinities with the tentaculitids (incertae sedis) and is… 
The worm endosymbionts in tabulate corals from the Silurian of Podolia, Ukraine
TLDR
Two endosymbionts, Chaetosalpinx sibiriensis and Coralloconchus bragensis, occur in Silurian tabulate corals of Podolia and showed no preference for the favositid or heliolitid type of morphology.
Calcareous tubeworms of the Phanerozoic
Morphological similarities indicate that Palaeozoic problematic tubeworms, e.g. tentaculitids, cornulitids, microconchids, trypanoporids, Anticalyptraea, and Tymbochoos, form a monophyletic group.
Shell repair in Anticalyptraea (Tentaculita) in the late Silurian (Pridoli) of Baltica

Shell repair is common in the late Silurian (Pridoli) encrusting tentaculitoid tubeworm Anticalyptraea calyptrata from Saaremaa, Estonia (Baltica), and is interpreted here as a result of failed
Phenetic phylogenetics of tentaculitoids – extinct, problematic calcareous tube-forming organisms
TLDR
Tentaculitoids belong to Lophotrochozoa with a high degree of certainty and are best classified as “lophophorates”, most likely Brachiozoa.

The first record of cornulitids tubeworms from the early Late Ordovician of Spiti, Tethyan Himalaya, India
ABSTRACT Tentaculitoid tubeworms, an extinct invertebrate group, is being reported from the Ordovician strata of Spiti, Tethyan Himalaya, India. External and internal moulds of tentaculitoids are
Evolution of a dense outer protective tube layer in serpulids (Polychaeta, Annelida)
TLDR
Serpulid tubes with dense outer layers (DOL) give a characteristic smooth shiny appearance to the tube surface and presumably evolved as an adaptation against drilling predation by gastropods and to delay shell dissolution in the waters of the deep-sea under-saturated with calcium carbonate.

A new cornulitid genus from the Silurian of Gotland, Sweden
TLDR
A new genus and species Septalites septatus is described from the Silurian of Gotland that resembles Conchicolites in having a smooth tube interior with multiple septa, but differs in the greater number of septa and microlamellar tube structure.
THE TENTACULITID AFFINITIES OF ANTICALYPTRAEA FROM THE SILURIAN OF BALTOSCANDIA
TLDR
The problematic fossil Anticalyptraea Quenstedt, 1867, traditionally interpreted as a phorid gastropod, is here assigned to the Class Tentaculita, which closely resembles Trypanopora but differs from gastropods in having pseudopunctae and a vesicular shell structure.

TLDR
The adult shell of the enigmatic tubular Givetian fossil Trypanopora is comprised of an outer fibrous prismatic layer and an inner micro-lamellar layer, with local, closely-spaced disruptive punctation, suggesting an original calcite composition.
Palaeoecology and diversity of endosymbionts in Palaeozoic marine invertebrates: Trace fossil evidence
TLDR
A collapse in bioclaustration diversity and abundance during the Late Devonian is most significant among endosymbionts of host coral and calcareous sponge taxa that were in decline leading up to the Frasnian–Famennian mass extinction.

TLDR
The application of soft X-rays for age determination of coral associated polychaete is useful for determining the correct age.
