These would have inhabited what is today known as the Western Interior Seaway. The remains represent mid to large-sized (up to around 5 m in maximum body length) ichthyosaurians that are mainly based upon isolated teeth and vertebrae, although some partial skeletons have been recovered from both the USA and Canada. Most of these fossils have taxonomic affinities with platypterygiines, such as the ubiquitous ‘form genus’ Platypterygius. This taxon has historically been the default identification for most North American Cretaceous ichthyosaur specimens. However, in comparison with remains from elsewhere, the ichthyosaurian fossils from Texas have been relatively understudied. Here, I review the existing records and present a concise list of all Cretaceous ichthyosaurian material currently held in public museum collections across the state. I have recognized 11 Cretaceous ichthyosaurian occurrences from Texas, including an indeterminate tooth, numerous vertebral centra, and some fragmentary skeletal remains attributable to Platypterygius. Ichthyosaurians therefore demonstrably occupied the Cretaceous epeiric seas of Texas from at least the Albian to middle Cenomanian, a distribution that traverses both the western and eastern coastlines of the Western Interior Seaway during its early phase of southern epicontinental incursion.","PeriodicalId":50830,"journal":{"name":"Alcheringa","volume":"42 1","pages":"509 - 515"},"PeriodicalIF":1.3,"publicationDate":"2018-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03115518.2018.1523462","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59969559","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}

Nummulites perforatus (N. burdigalensis group) and N. beaumonti (N. discorbinus group) are recorded from a Priabonian limestone outcrop of the Mazyad Member, Dammam Formation, exposed along the eastern limb of Gebel Hafit Anticline, in the United Arab Emirates. Nummulites perforatus at this site is characterized morphologically by lenticular to inflated-lenticular tests with rounded edges, meandering septal filaments, dense granules on, and between, the septal filaments, chambers that are longer than high and a regular-shaped spire. Biometric studies have demonstrated that this new material from the United Arab Emirates is similar to specimens of N. perforatus previously described. N. beaumonti is here characterized morphologically by lenticular tests with slightly rounded peripheries, a relatively thick and irregular marginal cord, compact septal filaments that are curved initially but become radial and twisted around the polar area with a slight flexure towards the periphery, tight to lax coiled spire, and chambers that are rectangular in shape and higher than long, including a rudimentary polar pustule. Biometric studies revealed that this material is comparable with specimens of N. beaumonti. Nummulites perforatus and N. beaumonti span the SBZ19 zone and are considered to be late Eocene (Priabonian) in age.

A sea scorpion claw from the Lower Devonian of China (Chelicerata: Eurypterida). Alcheringa 38, XX–XX. ISSN 0311–5518. An isolated chelicera (claw) of a pterygotid eurypterid is described from the Lower Devonian Xitun Formation of Yunnan Province, China. It is different from chelicerae of other pterygotids in having four principal denticles and at least four intermediate denticles between the principal denticles on both rami. This Chinese pterygotid, estimated at about 70 cm long, was a top predator that probably hunted small, primitive fishes, such as galeaspids. This discovery represents the first record of Pterygotidae from Asia and the third fossil eurypterid from China.
