They are historically important because fossils of British iguanodontians were among the first to be recognised as the gigantic reptiles that formed the basis for naming Dinosauria. However, the early stages of their evolution remain obscure because of a sparse fossil record, and taxonomic and systematic controversies among non-hadrosaurid iguanodontians abound. In order to shed light on the early stages of iguanodontian evolution, new discoveries and re-interpretations of historic specimens are crucial. Here, we redescribe the Late Jurassic early-branching iguanodontian Cumnoria prestwichii from the Kimmeridge Clay Formation of Oxfordshire, UK, and assess its phylogenetic position. We find that Cumnoria is distinct from the North American taxon Camptosaurus, with which it was previously synonymized, and is valid, possessing two autapomorphies of the pectoral girdle. We recover its phylogenetic position as a non-ankylopollexian iguanodontian. Cumnoria represents one of just four valid ornithopod taxa from the Jurassic of Europe.","PeriodicalId":134015,"journal":{"name":"Monographs of the Palaeontographical Society","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125417257","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

British Silurian stromatoporoids. Fauna, palaeobiology, and palaeogeographical significance. Monograph of the Palaeontographical Society, London: 1-92; pls 1-22. (Publ. No. 660, part of Vol. 175 for 2021.) British Silurian stromatoporoids occur in carbonate rocks, mostly in the Wenlock Series, together with a small number in the Llandovery Series and very few in the Ludlow Series. Using field and museum material (408 samples) and literature, this study identifies 15 stromatoporoid genera, doubling the previously known generic diversity, so the British Isles holds the third highest genera-diversity Wenlock assemblage after Gotland/Estonia (23 genera) and the Siberian Platform (20 genera). Remarkably, nearly all samples come from the small (100 × 100 km) Much Wenlock Limestone Formation (MWLF) (Homerian Stage, uppermost Wenlock Series) in the Midland Platform of central England (Avalonia), surrounded, underlain, and overlain by siliciclastics. On the Midland Platform one sample is Llandovery age; 11 samples are Ludlow age (Aymestry Limestone). Other samples from the Isle of Man (Wenlock age, six samples) and south-west Scotland (Llandovery age, three samples) are in transported material, with associated corals and they indicate unpreserved carbonate platforms in northern Britain. A few Llandovery Series stromatoporoids are also reported from Ireland, both north and south of the Iapetus Suture; published reports of Wenlock stromatoporoids from Ireland are shown to be misidentified trace fossils. In the MWLF stromatoporoids (together with the more abundant rugose corals, tabulates, heliolitids, and some microbial carbonates) occur in small patch reefs and in bedded bioclastic grainstones, packstones, and nodular wackestones; stromatoporoids are more common in and near patch reefs. The MWLF stromatoporoid fauna has 15 confirmed low-level taxa: Labechia conferta (Lc), Lophiostroma schmidti (Ls), Ecclimadictyon macrotuberculatum (Em) and E. astrolaxum (Ea), Petridiostroma simplex (Ps) and P. linnarssoni (Pl), Actinostromella vaiverensis (Av), Araneosustroma fistulosum (Af), Densastroma pexisum (Dp), Plectostroma intertextum (Pi), Simplexodictyon yavorskyi (Sy), Eostromatopora impexa (Ei), ‘Stromatopora’ venukovi (‘S’v), Syringostromella borealis (Sb) and Parallelostroma typicum (Pt). No new taxa were found. The five most abundant taxa (Lc, Av, Dp, Px, and Sb) total 230 specimens, 64.2% of the MWLF assemblage, consistent with taxa proportions in other Palaeozoic stromatoporoid assemblages. The stromatoporoids have limited growth forms: Lc grew laminar frames, mostly in patch reefs; the other taxa range from laminar to high domical, maximum sizes around 40 cm basal diameter. They almost completely lack the complexities and diversities of form of their contemporaries in nearby large carbonate platforms of Baltica (Gotland/Estonia) and Laurentia (eastern USA","PeriodicalId":134015,"journal":{"name":"Monographs of the Palaeontographical Society","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124287551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their previous study is summarised. The stratigraphy is reviewed and lithostratigraphic logs are provided for the mammal-bearing localities. The new Fort Victoria Member replaces the previous restricted use Cliff End Member in the Headon Hill Formation. Seventeen species-group taxa of the placental euarchontan family Nyctitheriidae are described, with the new genera Actinyctia and Cheilonyctia and the new species Amphidozotherium gassoni, Actinyctia bulbodens, Cheilonyctia lawsoni, Scraeva yulei, Euronyctia curranti and E. plesiolambda. The occurrence of Saturninia mamertensis near the base of the Headon Hill Formation extends its range from the Bartonian to early Priabonian. The occurrence of Oligonyctia hoffmani in the Bembridge Limestone Formation and lower Hamstead Member extends its range from the early Rupelian to the late Priabonian. A phylogenetic analysis of European Bartonian–Rupelian Nyctitheriidae results in an expanded subfamily Amphidozotheriinae and a new subfamily Saturniniinae for Saturninia (s.s.), Cryptotopos and Oligonyctia. Cryptotopos communis and Euronyctia recta from the German Oligocene are transferred to the genus Paradoxonycteris, whilst Sigenyctia (type species S. oligocaena) is synonymised with the genus Euronyctia. Saturninia mamertensis and S. grandis are shown not to be members of this genus. Euronyctia curranti, E. plesiolambda and E. oligocaena form a stratigraphical morphocline, suggestive of an evolutionary sequence. A phylogenetic analysis of primitive eutherians confirms Nyctitheriidae as stem members of the superorder Euarchonta, supporting an earlier analysis.
