We describe four labechiid stromatoporoid species, Labechia variabilis Yabe & Sugiyama, 1930, Labechiella mingshankouensis (Ozaki, 1938), Thamnobeatricea suxianensis (Dong, 1982), and Sinodictyon columnare Yabe & Sugiyama, 1930 from the Middle Ordovician Machiakou Formation in the Xiaonanhai section near Anyang City in northern Henan Province of China. The conodont Plectodina onychodonta occurs in association with these labechiids, implying a middle to late Darriwilian age. This assemblage extends the stratigraphic range of early stromatoporoids in North China to as early as the middle Darriwilian, thus slightly older than the previously known late Darriwilian earliest records. Mutual encrustations of Labechia variabilis and Labechiella mingshankouensis in the present assemblage constructed a microbioherm, together with unidentified tubular organisms, Ortonella-like calcimicrobes, a tubeworm-like organism, and borings. The assemblages of the Darriwilian labechiid stromatoporoids vary from place to place palaeogeographically in the shallow epicontinental marine environment of North China, i.e., in a patchy manner. The significant diversification of Darriwilian labechiid stromatoporoids in North China was likely promoted by a combination of environmental and ecological factors, which include: (1) the occurrence of a very shallow epicontinental marine environment, (2) a possible increase in the carbonate saturation state in seawater, (3) favourable seawater temperature for stromatoporoids during the Middle Ordovician and (4) the scarcity of bryozoans and corals as ecological competitors in North China.","PeriodicalId":272731,"journal":{"name":"Alcheringa: An Australasian Journal of Palaeontology","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126552326","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}

They are included in the Halstätt-like Lilu Facies of the Bandeira Group. Age-diagnostic involutinid foraminiferal species, not previously recorded from Timor, include Involutina liassica, Trocholina sp. ex. gr. Trocholina turris and Lamelliconus permodiscoides, which collectively indicate a Rhaetian age, possibly ranging down to the Sevatian. The conodont Norigondolella steinbergensis, recorded low in the section, is consistent with this age determination. The Lilu Facies was deposited at a water depth of a few tens of metres, as suggested by the presence of extensive cyanobacterial borings into shell fragments and the presence of microbial laminations including the presence of stromatolites and bacinellid-like fabrics. Among macrofossils, common ammonoids are present in the section, and marine reptile bones are conspicuous in the lower beds. Other biogenic components of the rock observed in acetate peels and thin sections are abundant echinoderm debris (including pentacrinoid columnal plates), bivalve fragments and micro-gastropods, rare siliceous sponge spicules, solitary corals, and brachiopod debris. In the studied region, a major drowning of a shallow-marine carbonate platform took place probably in the Rhaetian or possibly latest Norian. Similar ‘ammonitico rosso limestone’ interbedded with thick-bedded limestones of a shallow-marine carbonate platform is present in the uppermost Triassic of Seram. More detailed biostratigraphical comparisons and correlations of similar units in Timor and other nearby islands may indicate a general marine drowning of Late Triassic carbonate platforms, at least in the northern part of the East Gondwana Interior Rift system, during the Rhaetian or possibly latest Norian.","PeriodicalId":272731,"journal":{"name":"Alcheringa: An Australasian Journal of Palaeontology","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127999932","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}

However, despite the fact that this was the first dinosaur tooth found in Australia (and the only one prior to 1963), this specimen was not, and has never been, formally described. Herein, we describe this opalized theropod tooth, which almost certainly derives from the Griman Creek Formation (Upper Cretaceous; lower to mid-Cenomanian). Despite its relatively poor preservation, several morphological features are consistent with attribution to Megaraptoridae. Smith Woodward’s theropod tooth can now be recognized as one of the first megaraptorid fossils found worldwide. Furthermore, it reinforces the proposal that megaraptorids were an important component of mid-Cretaceous faunas in eastern Australia.

However, Miocene Microporella records in New Zealand are scarce, and currently limited to a single middle Miocene species identified as Microporella hyadesi (a Recent bifoliate erect form originally described from Cape Horn and Tierra del Fuego) from the Mt. Brown ‘E’ Limestone Formation of North Canterbury. Here, we describe and illustrate three new early Miocene (Otaian–Altonian New Zealand stages corresponding to the Aquitanian–Burdigalian) species, namely Microporella incurvata sp. nov., M. gladirostra sp. nov. and M. whiterocki sp. nov., that represent the geologically oldest regional examples of the genus to date. A fourth species is left in open nomenclature because complete ovicells are not preserved in the only recovered specimen. The colonies of Microporella were collected from several rock formations exposed in limestone quarries on the South Island. The three new species share ovicells with a personate structure, but differ in the appearance of the ooecial surface (evenly pseudoporous versus imperforate), shape of the ascopore opening (cribrate versus non-cribrate), number of oral spine bases, and shape of the avicularian rostrum and crossbar. We also illustrate for the first time ovicells of another fossil species, Microporella rusti, from the Pleistocene Nukumaru Limestone Formation of the Wanganui Basin on the North Island. The ovicells of this taxon are rare, being found in only six of several hundred specimens collected to date. The ovicells of M. rusti are also very large, covering the entire orifice of the maternal zooid, similar to those of some other Microporella species all characterized by erect bifoliate colonies contrasting with the encrusting colonies of M. rusti. http://zoobank.org/urn:lsid:zoobank.org:pub:5430969F-B75B-40E7-8F65-74CDC87AA662 Mali H.

Here, we describe pathologies on the tooth plates of Metaceratodus baibianorum from the Late Cretaceous (Maastrichtian) La Colonia Formation of Patagonia in Argentina. Of the total number of analysed tooth plates (N = 127), 27.5% show signs of different pathologies including caries, abscesses, hyperplasia, fractures, alterations in growth, and erosion. No tooth plates with parasitic invasions, attrition or osteopenia were observed. Some examples of occlusal caries show pulpal overgrowths on the pulp surface. CT scanning demonstrates that these are similar to tertiary dentine in their coincidence with lesions, higher density relative to the surrounding dentine, and fewer pulp canals resulting in fewer dentinal tubules. Such features may indicate that dipnoans are, or at least were, able to generate some form of reparative or reactionary dentine.

The majority of Australia’s pterosaur remains have been discovered in the Eromanga Basin of Queensland, specifically the upper Albian Toolebuc Formation, upper Albian Mackunda Formation, and Cenomanian–lowermost Turonian Winton Formation. In this paper, we describe two new partial pterosaur femora from the Toolebuc and Winton formations. Despite being incomplete, these specimens can be assigned to Anhangueria. Pairwise comparisons demonstrate differences in the deflection of the femoral head. Moreover, a subtle ridge on the posterior surface of the Toolebuc Formation femur is not visible on the specimen from the Winton Formation. The greater trochanter of the Winton Formation femur also preserves a potential bite mark that is tentatively attributed to a crocodylomorph. These new pterosaur fossils supplement the currently limited understanding of pterosaur diversity from Australia, and attest to the cosmopolitan distribution of anhanguerians during the Early to mid-Cretaceous.
