We report the associated fauna composed of foraminifers, radiolarians, crinoids, echinoids and ostracods that all point to seepage at bathyal depth. The foraminifer assemblage and the occurrence of the irregular echinoid Tithonia oxfordiana together point to a middle Oxfordian age. We provide an in-depth analysis of the ostracod community, which is the oldest so far reported in such environments. The new species Procytherura praecoquum may be cognate to the seepage site and could illustrate the oldest known example of pore clusters, sometimes proposed as representing ectosymbiosis. The Sahune assemblage demonstrates that cold seep ostracod communities were already a mixture of taxa from platform and deep-sea oligotrophic environments. The post-Jurassic diversification of ostracods at cold seeps was related to colonization events and diversification of families that have been inhabitants of such ecosystems at least since the Oxfordian. The Sahune record changes our current conception of the deep-sea colonization by the ostracods Tethysia and Procytherura that occurred earlier than traditionally considered.</div>","PeriodicalId":55116,"journal":{"name":"Geobios","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141298315","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, the Upper Triassic coal-bearing strata which alternate between marine and terrestrial deposits yield diverse and abundant fossil plants, ammonites and bivalves. These strata provide a significant reference for the study of palaeoenvironmental variations in the lower latitude regions. In this paper, we review the major progress on Late Triassic floral studies in this area. Specifically, we compare the regional plant assemblages from different fossil sites in central and northern Guangdong which have been dated with marine fauna. 155 species belonging to 56 genera of fossil plants have been reported so far in northern and central Guangdong. The Late Triassic floras in Guangdong are mainly composed of Bennettitales and ferns, followed by horsetails, seed ferns, cycads, ginkgos and conifers. In ascending order, four regional plant fossil assemblages can be recognized in the Late Triassic deposits, namely the Pachypteris-Lindleycladus Assemblage (Julian), the Pterophyllum-Baiera Assemblage (late Julian), the Clathropteris-Otozamites Assemblage (Tuvalian), and the Danaeopsis-Anomozamites Assemblage (Rhaetian). In general, the Late Triassic climate in the Guangdong region was mainly humid and warm and either tropical or subtropical. The fossil plants corroborate palaeomagnetic evidence that the central and northern Guangdong region was located at approximately the same latitude as it is today and formed the southern coastline of the South China Block during the Late Triassic. Palaeogeographically, the transgression started at the end of the Julian and the south coastal terrane consisted of a western bay, a peninsula and an eastern bay. During the regression period, post-Rhaetian, the bays evolved into a gulf coastal plain.</div>","PeriodicalId":55116,"journal":{"name":"Geobios","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141298142","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although they were major components of many benthic communities, current understanding on how this group diversified during the Cambrian remains limited. Clarifying these confusions about the diversification of chancelloriids requires new information provided by new studies of previously described and/or new material. Considering the emerging scenario of chancelloriids, the sack-like chancelloriids from the Stage 4 Balang Lagerstätte are restudied on the basis of previous collections, which are herein separated from Chancelloria eros Walcott, 1920, and revised as Archiasterella acuminata nov. sp. and Chancelloriidae gen. et sp. indet. The Ar. acuminata specimen is well preserved and does show its scleritome and sclerite characters, while the Chancelloriidae gen. et sp. indet. specimen is poorly preserved and its scleritome and sclerite characters are difficult to distinguish. By combining information from previous studies and the present research, data on chancelloriid occurrences in South China indicate that chancelloriids had once diversified in the Cambrian South China, evidenced by high-level richness of sclerite-based taxa during the late Fortunian to the middle Stage 3, and of sclerite formulas during the late Stage 2 to the Wuliuan. The result is inconsistent with the recent viewpoint that there were two flourishing ages of chancelloriids in South China.

Remains from Pentalophos and Ravin de la Pluie were described as congeneric with the Iberian Deccenatherium, although they were later attributed to a new, distinct genus known by three different species: Palaeogiraffa macedoniae, Palaeogiraffa pamiri, and Palaeogiraffa major. The type species of the genus, Pg. macedoniae, was based on the most abundant Pentalophos material, while the rest of the species was established mainly on size difference criteria. Here we provide a review of the Palaeogiraffa material in order to (i) test its validity, (ii) re-discuss hypotheses about the genus phylogenetic relationships with other Late Miocene giraffids, and (iii) re-explore intrageneric diversity and number of recognized species based on the available Eastern Mediterranean samples. We confirm Palaeogiraffa as a distinct genus from other Late Miocene giraffids based on its unique proportions, as well as its dental and postcranial morphology. Furthermore, we endorse the likelihood of Palaeogiraffa being phylogenetically linked to the sivatherine lineage, based mainly on its dental and metatarsal morphological features. The generic attribution of specimens from Xirochori, Ravin de la Pluie, Middle Sinap, Yulafli and Küçükçekmece to Palaeogiraffa is adequately supported by the present data.
