Figure 6. Cyclostome protoecial pseudopore patterns mapped onto a in Ancestrular morphology in cyclostome bryozoans and the quest for phylogenetically informative skeletal characters
Figure 6. Cyclostome protoecial pseudopore patterns mapped onto a molecular phylogeny. Numbers correspond to the patterns defined in the text (no species of Pattern 2 have been sequenced to date). Brackets signify that the pattern has been observed in a congener of the sequenced species and 'iw' an interior walled protoecium, which cannot have pseudopores. Diagrammatic figures of the patterns are shown next to the pattern numbers. Pattern 1 has been assigned to sequenced Crisia spp. based upon observations of a congener (Crisia eburnea) from the literature (Nielsen 1970; Silén 1977). The outgroup taxon for this phylogeny, based on Taylor, Waeschenbach, et al. (2015), is the phylactolaemate Pectinatella magnifica which lacks a mineralized skeleton and therefore a protoecium. Tree topology generated from Bayesian analysis of a concatenated lsrDNA and ssrDNA dataset. All nodes with <0.95 posterior probability were collapsed. See Taylor, Waeschenbach, et al. (2015) for full details.
Figure 5 in Ancestrular morphology in cyclostome bryozoans and the quest for phylogenetically informative skeletal characters
Figure 5. Patterns of protoecial pseudopore distribution represented diagrammatically using simplified drawings of ancestrula in which the pseudopores are shown as small black dots on the protoecium and the aperture of the ancestrula is the black circle at the distal end. The eight recognized patterns are depicted around the circumference of a pie chart showing their relative abundances among 74 species of cyclostomes (51 Recent and 23 fossil).
Figure 2. Cyclostome protoecia showing Pattern 1 in Ancestrular morphology in cyclostome bryozoans and the quest for phylogenetically informative skeletal characters
Figure 2. Cyclostome protoecia showing Pattern 1 in which there are no pseudopores on the protoecium (the irregularly distributed holes in (d) are microborings). (a) Filicrisia geniculata, Wembury, Devon, UK; the erect ancestrular tube and two lateral buds have articulated joints with the protoecium and sparse, elongate pseudopores. (b) Lichenoporid?, Akkeshi Bay, Hokkaido, Japan. (c) Tubulipora occidentalis, Pacific Grove, California, USA; note radial ridges on protoecium. (d) Platonea sp. 1, Otago Shelf, NZ; the irregularly distributed holes in the protoecium are interpreted as microborings. (e) Stomatopora sp. 1, Jurassic, Bathonian, Somerset, UK; the coarse, pseudoporous wall of the distal ancestrular tube contrasts with the smooth, non-pseudoporous protoecium. (f) Oncousoecia sp., Jurassic, Upper Callovian, Oxfordshire, UK; note plugged pseudopores on the distal ancestrular tube. Scale bars: 100 µm.
Figure 4. Cyclostome protoecia showing Pattern 6 in Ancestrular morphology in cyclostome bryozoans and the quest for phylogenetically informative skeletal characters
Figure 4. Cyclostome protoecia showing Pattern 6 (a, b), Pattern 7 (c, d) and Pattern 8 (e, f). (a) Diaperoecia purpurascens, Whangaroa Harbour, New Zealand. (b) 'Heteropora' neozelanica, Spirits Bay, New Zealand. (c) Annectocyma major, English Channel, UK; central part of protoecium is damaged. (d) Stomatopora cf. dichotomoides, Jurassic, Bathonian, Somerset, UK. (e) Crisulipora occidentalis, Long Beach, California, USA; the pseudopores in this species are occluded by perforated plates, making them less clearly visible. (f) Cinctipora elegans, Otago Shelf, New Zealand.
Figure 1 in Ancestrular morphology in cyclostome bryozoans and the quest for phylogenetically informative skeletal characters
Figure 1. Cyclostome protoecia with interior-walled calcification. Disporella hispida, Stoke Point, Devon, UK. (a) Protoecium with narrow band of exterior wall surrounding an area of pustulose interior wall. (b) Crenulated ridge separating exterior- and interior-walled calcification of another protoecium. Hornera?robusta, Otago Shelf, NZ. (c) Juvenile colony with new zooids formed directly on the ancestrular surface. (d–f) Protoecium of irregularly porous, pustulose interior-walled calcification with erect distal ancestrular tube. Scale bars: 100 µm, except (e) which is 50 µm.
Figure 3. Cyclostome protoecia showing Pattern 2 in Ancestrular morphology in cyclostome bryozoans and the quest for phylogenetically informative skeletal characters
Figure 3. Cyclostome protoecia showing Pattern 2 (a), Pattern 3 (b–d), Pattern 4 (e) and Pattern 5 (f–i). (a) aff. Liripora, Pleistocene, Kuromatsunai, Japan. (b) Plagioecia patina, Ferrol, Galicia, Spain. (c) Stomatopora incurvata, English Channel, UK. (d) Oncousoecia dilatans, Shetland, UK. (e) Microeciella suborbicularis, English Channel, UK. (f) Entalophoroecia deflexa, English Channel, UK. (g) Microeciella aff. suborbicularis, Port Cros, Mediterranean. (h) Mesonopora concatenata, Jurassic, Middle Bathonian, Somerset, UK. (i) Hyporosopora incrustans, Jurassic, Bathonian, Wiltshire, UK. Scale bars: 100 µm.
