In terms of structure, semantic and grammatical features of their elements, as well as types of compound indicators, they resem-ble typical three-argument series (child and mother), however, they differ in the number of noun elements, which usually range from three to seven. Two types of lists are distinguished: homogenous, are organized around a single type of linking element or its equivalent in the form of a delimitation pause (e.g., aby mię od ciebie ani śmierć, ani żywot, ani żadna szczęsność od ciebie oddaliła), and heterogeneous, which may be linked more loosely or more closely (e.g., Gdyby raćce z przysiężniki i z pospólstwem uczynili wielkierz). List syntax was also described; very rarely it was exclusively ad sensum, more frequently, exclusively ad formam or in some cases, ad formam/ad sensum. The lists extracted here resemble modern serial subjects in terms of structure and syntax and, according to quantitative analyses, have a similar frequency in the oldest known Polish sentences.","PeriodicalId":50887,"journal":{"name":"Acta Palaeontologica Polonica","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75926755","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cloutier","doi":"10.4202/app.00841.2020","DOIUrl":"https://doi.org/10.4202/app.00841.2020","url":null,"abstract":"Lungfishes are one of the few early vertebrate clades with a rich 410-million-years-old fossil record. Lungfishes are characterized by a low evolutionary rate assumed to be associated with paedomorphosis since the Late Devonian. Lungfish paedomorphic trends include a reduction of the number of median fins, reduction of the number of cranial dermal bones, and reduction of the degree of neurocranial ossification. This neurocranial trait has evolved from heavily ossified in Devonian species to completely cartilaginous in post-Devonian species. Neurocranial conditions among derived Devonian lungfishes are needed to have a better understanding of paedomorphosis as a driving force during lungfish evolution. The neurocrania of two Devonian species, Scaumenacia curta (middle Frasnian, Escuminac Formation, eastern Canada) and Pentlandia macroptera (Givetian, Orcadian Basin, Scotland), have been micro-CT-scanned. These species were assumed to have a cartilaginous neurocranium like other “phaneropleurids” and “fleurantids”. Juvenile (or sub-adult) and adult specimens of S. curta possess cartilaginous neurocrania, whereas P. macroptera is now recognized to have a poorly ossified neurocranium. Pyrite filled neurocranial cavities preserving some endocranial structures (e.g., olfactory bulbs, semicircular canals) allow us to code for phylogenetic endocranial characters in S. curta. This unique mode of preservation suggests that occasionally pyrite is a preservative rather than a destructive diagenetic agent. In the evolutionary gap between Pentlandia and Scaumenacia, paedomorphosis had already resulted in reduction of neurocranial ossification while little changes occurred in cranial dermal bones.","PeriodicalId":50887,"journal":{"name":"Acta Palaeontologica Polonica","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70478855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An overview of the fossil odonatans from the Paleocene of Menat (France) is provided. We describe the anisopteran Macrogomphus menatensis sp. nov., first fossil representative of the family Epigomphidae, together with two zygopteran, viz. the dysagrionid Menatagrion hervetae gen. et sp. nov., and the new family Menatlestidae fam. nov., with its type species Menatlestes palaeocenicus gen. et sp. nov. The genus Menatagrion gen. nov. is the first Paleocene record of the Dysagrionidae, otherwise known by a putative Cretaceous genus and several Eocene to Miocene genera. Menatlestes gen. nov., putatively attributed to the stem-group of the Lestinoidea (Megalestidae and Lestidae), would correspond to the oldest record of this clade. With these three new taxa, and the previously described Thanetophilosina menatensis , Valerea multicellulata , “ Lestes ” zalesskyi , and an Aeshna species indet., the total number of Odonata from Menat goes up to seven species in total; two Anisoptera and five Zygoptera. Furthermore, we propose new evidences showing that the head characters defining the putative suborder Cephalozygoptera are due to deformations, very frequent among the fossil Odonatoptera. We treat the Cephalozygoptera as a junior synonym of Zygoptera.","PeriodicalId":50887,"journal":{"name":"Acta Palaeontologica Polonica","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70479672","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This provides an exceptional window for investigating the rapid divergent evolution of animal phyla in the early Cambrian ocean. However, the fossil eukaryotic algae are poorly documented and are not properly incorporated into the conceptual food web of the Cambrian ocean ecosystem. In this study, we report a new taxon of calathiform alga, Calathophycus irregulatus Tang gen. et sp. nov., and an indeterminate alga, from the Kuanchuanpu biota. Calathophycus irregulatus can be distinguished from other reported phosphatized multicellular algal fossils from the Kuanchuanpu biota and the Ediacaran Weng’an biota (Guizhou Province, China), based on the external morphology and features of cell clump aggregation. The observation of C. irregulatus and the indeterminate alga indicates a certain diversity of algae at the beginning of the Cambrian. Concerning the regularly or irregularly shaped multicellular algal fossils from the Kuanchuanpu Formation, co-occurring spherical fossils, previously interpreted as “cleavage stage” of animal embryos, should be reconsidered in affinity.","PeriodicalId":50887,"journal":{"name":"Acta Palaeontologica Polonica","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70479901","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Jeon, Yue Li, Wenkun Qie","doi":"10.4202/app.00954.2021","DOIUrl":"https://doi.org/10.4202/app.00954.2021","url":null,"abstract":"Stromatoporoids from a Middle Devonian reef in South China and their palaeoecological implication. Acta Palaeontologica Polonica 67 (X): xxx–xxx. Stromatoporoids are the major constructors of a Givetian (Middle Devonian) fossil reef in shallow marine facies, in the Jiwozhai Member of the Dushan Formation, at Dahekou, near Dushan, Guizhou Province, South China. Stromatoporoids, together with other reef building and dwelling components (rugose corals, tabulates, chaetetids and others), form a high diversity community, making the Jiwozhai reef a palaeobiodiversity hotspot. In this study 11 species belonging to nine genera and four orders are identified, including Gerronostromaria grossum (Clathrodictyida), Pseudotrupetostroma porosum , and Salairella buecheliensis (Stromatoporida), Clathrocoilona spissa , Stictostroma sag­ inatum , and Synthetostroma actinostromoides (Stromatoporellida) and ? Habrostroma laminosum , Parallelopora sp., Stachyodes costulata , Stachyodes fasciculata and Stachyodes sp. (Syringostromatida). Among them, Clathrocoilona spissa and Gerronostromaria grossum are the most abundant stromatoporoid taxa. Stromatoporoid growth form, size, substrate and growth interruption are considered to be key autecological parameters to evaluate their growth behaviour and contribution in reef formation. Skeletons of laminar Clathrocoilona spissa are commonly smaller (up to 40 mm in basal dimension and less than 2 mm in thickness) than other stromatoporoid taxa and frequently encrusted on other organisms. In contrast, Gerronostromaria grossum dominates the assemblage, with its larger laminar growth form (up to 500 mm in basal dimension and 40 mm in thickness) expanding both on bioclastic and clay-rich micritic substrate and shows repeated growth interruptions, altogether evidence that this taxon was resilient to environmental pressure and may have pioneered the reef development. The variation of growth preference among stromatoporoid taxa therefore indicates a different growth strategy of each stromatoporoid in this reef environment.","PeriodicalId":50887,"journal":{"name":"Acta Palaeontologica Polonica","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70480065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
