Symbiotic associations are key interactions in benthic ecosystems; they drive evolutionary
changes that influence the complexity of life. Out of the major groups of Phanerozoic corals …

This study describes diverse assemblages of serpulid and sabellid polychaetes from various
Middle and Upper Jurassic (upper Bajocian to lower Kimmeridgian) deposits of the Polish …

Organisms encrusting corals from a coral horizon encountered in a trench in the Middle
Devonian (Givetian) Pokrzywianka Beds of the classic Grzegorzowice-Skały section in the …

The mineral composition and tube ultrastructure of the Middle and Upper Jurassic
calcareous sabellid Glomerula gordialis from the Polish Basin have been assessed. In all …

Trepostome bryozoans, with their thick calcitic skeletons, formed the largest number of
symbiotic associations with endobionts in the Phanerozoic. Such associations were also …

The fossil record yields a peculiar phenomenon in different kinds of molluscan shells:
bioclaustrations formed around (epi) symbionts during growth of the hosts' shell margin …

There was a sudden increase in the diversity of bioclaustrations in the Sandbian (Late
Ordovician) that continued somewhat more slowly in the Katian. The Sandbian was also the …

The ultrastructural diversity of the Middle and Late Jurassic serpulid tubes from the Polish
Basin has been investigated. The inspection of 12 taxa representing the two major serpulid …

ABSTRACT A phoronid-like hederelloid that formed a symbiotic association with the
rugosan coral Entelophyllum has been found in the Pridoli Series of Estonia. The skeletons …

Throughout their evolutionary history, serpulids, the calcareous tube-dwelling suspension-
feeding polychaetes, formed symbiotic relationships with cnidarians (32 relationships) …
