“…It therefore created a new ecological niche and allowed partial escape from the limited bottom surface. A similar case was described by Suárez-Andrés et al 18 , 21 from the Lower Devonian of Spain, who interpreted the relationship as commensalism.…”

“…One could hypothesize that cnidarian biology fit well with bryozoans as they likely consumed food particles of different sizes and cnidarian symbionts could protect the host bryozoan with its cnidae. Last, but not least, a successful mutualism, allowing the use of a new feeding tier could prompt its more common appearance, as evidenced by a number of similar associations described from various parts of the World—e.g., the Early Devonian of Spain 18 , and Czechia 68 or Middle Devonian of Russia (Kuznetsk Basin 69 ). For a review on palaeogeographical distribution of such forms, see 18 .…”

“…This can likely be extended to other bryozoan–cnidarian associations. While several such associations are known from the Devonian e.g., 16 , 18 , 20 , 21 they are less frequent in older strata e.g., 9 , 22 .…”

“…While diverse benthic species may use aggressive chemicals or toxins to repel potential predators or competitors 12 , the abilities of bryozoans to produce repellent chemical agents are probably rare 13 , and therefore these organisms are generally prone to overgrowths by other organisms. As a result, bryozoan–cnidarian associations are common in modern seas 14 , 15 , and numerous cases have been described from the fossil record 16 – 18 . Among these, representatives of Hydrozoa are particularly common symbionts of bryozoans.…”

Bryozoans were common benthic invertebrates in the Silurian seas. The large biodiversity among Silurian benthic organisms prompted diversified interactions, and as a result bryozoans hosted many other organisms as symbionts. Here we analyse the cystoporate bryozoan Fistulipora przhidolensis and unidentified trepostomes intergrown with auloporid tabulate corals and putative hydrozoans. The material comes from the uppermost Přídolí Series (Late Silurian) of the Sõrve Peninsula, Saaremaa, Estonia. Our analysis shows that the interaction was beneficial for both organisms—cnidarians benefited from feeding currents created by the host bryozoan, while the latter benefited from the protection from predators by cnidae, it can thus be classified as mutualism. Such associations are common in modern seas. The analysed organisms are typically encrusting when the symbiosis is absent, when intergrown they display erect, branching morphologies, raised over the substratum, thus exploiting a higher suspension-feeding tier. While similar associations were known from the Devonian, we demonstrate that this novel ecological strategy for greater resource exploitation started as early as the latest Silurian.

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. Four morphologies, two of them formerly considered bioerosion traces, are here united in the parataxonomy of bioclaustration structures under the revised cecidogenus Rodocanalis. These are: (1) simple linear grooves (Rodocanalis linearis csp. nov.) formed below the periostracum in Pleistocene to Recent endobenthic bivalves;(2) series of distally ramifying grooves (Rodocanalis runicus) in Silurian orthoconic nautiloids; (3) irregular networks of grooves (Rodocanalis reticulatus) in Jurassic to Cretaceous bivalves and gastropods; and (4) regular reticulate networks (Rodocanalis geometricus csp. nov.) in Jurassic to Cretaceous gastropods. The linear grooves might be associated with commensal worms, while multiple lines of reasoning point towards hydrozoan symbionts in the case of the
