“…The earliest known intergrowth association involved the early bryozoan Orbiramus and diverse sclerobionts reported from the Early Ordovician of South China (Ma et al, 2021). Bryozoans commonly hosted various endobionts, such as cornulitid tubeworms and rugose corals, in the subsequent stages of the Ordovician (e.g., Vinn and Mõtus, 2012; Vinn et al, 2014, 2016, 2017, 2018a, b, 2019) and later (e.g., Plusquellec and Bigey, 2019; Sendino et al, 2019). By contrast, early stromatoporoids (i.e., labechiids) seemingly did not involve intergrowth associations during the late Early to early Late Ordovician interval.…”

Clathrodictyids are the most abundant stromatoporoids in the Upper Ordovician Xiazhen Formation (middle to upper Katian) of South China. A total of nine species belonging to four clathrodictyid genera are identified in the formation, including Clathrodictyon idense Webby and Banks, 1976, Clathrodictyon cf. Cl. microundulatum Nestor, 1964, Clathrodictyon cf. Cl. mammillatum (Schmidt, 1858), Clathrodictyon megalamellatum Jeon n. sp., Clathrodictyon plicatum Webby and Banks, 1976, Ecclimadictyon nestori Webby, 1969, Ecclimadictyon undatum Webby and Banks, 1976, Camptodictyon amzassensis (Khalfina, 1960), and Labyrinthodictyon cascum (Webby and Morris, 1976). The clathrodictyid fauna in the Xiazhen Formation is very similar to those from both New South Wales and Tasmania, although the latter two Australian regions do not share any common clathrodictyid species during the Late Ordovician. The paleobiogeographic pattern indicates that the northward drift of South China resulted in a favorable environment for the migration of clathrodictyids from other peri-Gondwanan terranes to South China. In addition, these peri-Gondwanan clathrodictyid species hosted various endobionts, representing a variety of paleoecological interactions. The high abundance and species-level diversity of clathrodictyid species presumably increased the substrate availability of suitable host taxa, judging from the diverse intergrowth associations between clathrodictyids and other benthic organisms. These paleoecological interactions between stromatoporoid and other organisms are known from the Late Ordovician and became more abundant and widespread in the Siluro–Devonian. Overall, the Late Ordovician clathrodictyid assemblage in South China demonstrates one of the highest species-level diversities among all peri-Gondwanan terranes and represents a precursor of the complex, clathrodictyid-dominated communities of later metazoan reefs during the Great Ordovician Biodiversification Event.

“…It is most likely a study bias and does not indicate real decline in bryozoan symbiosis after the Ordovician. More data are available about symbiotic bryozoans in the Devonian when bryozoans formed symbiotic associations with Chaetosalpinx (a bioclaustration) (Ernst et al 2014), rugosans (Sendino et al 2019; Plusquellec & Bigey 2019) and tabulate corals (McKinney et al 1990). However, the data for the Devonian are still limited as compared to the Upper Ordovician.…”

“…Most symbiotic bryozoans in the Palaeozoic are trepostomes (18 associations, with 72 genera according to Paleobiology Database 2020), while cystoporates were less symbiotic (seven associations, with 47 genera according to Paleobiology Database 2020) (Palmer & Wilson 1988; McKinney et al 1990; Ernst et al 2014; Vinn et al 2014; Vinn et al 2018b; Sendino et al 2019; Plusquellec & Bigey 2019; Vinn et al 2019). The other bryozoans are not known to have formed symbiotic associations in the Palaeozoic.…”

Symbiosis of cornulitids with the cystoporate bryozoan Fistulipora in the Pridoli of Saaremaa, Estonia

Cornulites sp. and Fistulipora przhidolensis formed a symbiotic association in the Pridoli (latest Silurian) of Saaremaa Island, Estonia. This Cornulites sp.-F. przhidolensis association is the youngest example of cornulitid-bryozoan symbiosis. Symbiosis is indicated by intergrowth of both organisms. The cornulitids are completely embedded within the cystoporate bryozoan colony, leaving only their apertures free on the growth surface of bryozoan. In terms of food competition, this association could have been slightly harmful to F. przhidolensis as Cornulites sp. may have been a kleptoparasite. There may have been a small escalation in the evolution of the endobiotic life mode of cornulitids as the number of such associations increased from the Ordovician to Silurian. It is likely that Palaeozoic bryozoan symbiosis reached its maximum in the Late Ordovician. Most of the symbiotic bryozoans in the Palaeozoic are trepostomes, and the diversity of symbiotic associations was also greatest among trepostomes. □ Baltica, bryozoans, cornulitids, Silurian, symbiosis.

“…Rodríguez et al (2010) described the reefal processes shown in the Guadámez-2 section. In contrast to the bryozoan faunas of SW Spain, those from the Lower-Middle Devonian of NW Spain were more intensively studied in a series of publications in more than two last decades (Suárez Andrés, 1998, 1999a, 1999b, 1999c, 2014Suárez Andrés & González Álvarez, 2000;Suárez Andrés & McKinney, 2010;Ernst, 2010Ernst, , 2011Ernst, , 2012Ernst et al, 2011Ernst & Buttler, 2012;Suárez Andrés & Ernst, 2015;, 2021, 2017, 2018Sendino et al, 2019). These studies show the high diversity and richness of bryozoans in the Lower to Middle Devonian sediments of Spain.…”

Lower to Middle Devonian rocks crop out at the Ossa-Morena Zone (SW Spain), between the Guadiana and Guadalquivir Valleys along 200 km (Fig. 1). The Devonian succession comprises more than 600 m of shales, sandstones, limestones and marls. The limestones show reefal features, but they have limited lateral and vertical development. The most complete successions of these reefal facies are located in five sections, Guadámez-2, Arroyo del Lobo, Zújar, Peñón Cortado and Arroyo del Pozo del Rincón (Rodríguez-García, 1978). Pragian reefal facies occur in most of these localities, being best exposed in the Peñón Cortado section. Emsian reefs are only developed in the Guadámez-2 section. During the field trip in 2007 rich bryozoan assemblages occurring in the reefal and peri-reefal facies were collected. The present paper aims the taxonomic description of the abundant and diverse Lower Devonian bryozoan fauna from the Peñón Cortado and Guadámez-2 sections at the Ossa-Morena Zone. Febrel (1963) first mapped the Devonian outcrops near the Valsequillo village, southern from the Sierra del Pedroso. Herranz (1970) and Llopis-Lladó et al. (1970) described the regional stratigraphy of the Sierra del Pedroso and surrounding region, including Precambrian and Palaeozoic rocks. They provided the first description of the Devonian regional stratigraphy. Both papers indicated the presence of reefal facies BACKGROUND
