title: Cretaceous soft-shelled turtles (Trionychidae) of Mongolia: new diversity, records and a revision

description: This paper is devoted to the description and revision of material of Cretaceous soft-shelled turtles (Trionychidae) of Mongolia. It includes the description of seven trionychid species, six of which are new, and two new genera: the cyclanorbine <i>Nemegtemys conflata</i> gen. et sp. nov. from the Nemegt Formation (Maastrichtian), and the trionychines <i>Gobiapalone breviplastra</i> gen. et sp. nov. from the Nemegt and Barungoyot (Campanian) formations, <i>G. orlovi</i> from the Baynshire Formation (Cenomanian–Santonian), ‘<i>Trionyx</i>’ <i>baynshirensis</i> sp. nov. from the Baynshire Formation, ‘<i>T</i>.’ <i>gilbentuensis</i> sp. nov. from the Nemegt Formation, ‘<i>T</i>.’ <i>gobiensis</i> sp. nov. from the Nemegt Formation, and ‘<i>T</i>.’ <i>shiluutulensis</i> sp. nov. from an unknown formation (Campanian). In addition, one shell from the ?Baynshire Formation of Khermin Tsav is assigned to <i>Gobiapalone</i> sp. The type material of <i>Amyda menneri</i> is considered to be Trionychidae indet. and <i>Amyda menneri</i> to be a nomen dubium. Finally, we revise other available materials of Cretaceous trionychids from 45 localities in Mongolia. <i>Nemegtemys conflata</i>, if correctly assigned, is the earliest known member of Cyclanorbinae. The two species of the new genus <i>Gobiapalone</i> are included in two phylogenetic analyses of Trionychidae. In both analyses <i>Gobiapalone</i> is monophyletic. In the first analysis, <i>Gobiapalone</i> is placed within Apalonina. In the second analysis, <i>Gobiapalone</i> is sister to Apalonina. Thus, the results of both analyses show that Apalonina, which is a rather advanced and well-supported trionychid clade, or its closest sister taxon (stem-Apalonina), were present in the Late Cretaceous of Asia. These results suggest that most other supra-generic clades of modern trionychids had been established in Asia by the Late Cretaceous. That suggestion is supported by the discovery of a cyclanorbine <i>Nemegtemys conflata</i> in the Late Cretaceous of Mongolia. Finally we summarize the latest data on temporal and geographical distributions of Cretaceous Trionychidae of Asia and North America.http://zoobank.org/urn:lsid:zoobank.org:pub:921DA1C5-C4B2-463D-A49D-608024C6036A

title: <i>Cretamerus vulloi</i> gen. et sp. nov., the oldest bark-gnawing beetle (Coleoptera: Trogossitidae) from Cretaceous amber

description: <i>Cretamerus vulloi</i> gen. et sp. nov., a fossil bark-gnawing beetle (Cleroidea: Trogossitidae), is described from the Cretaceous amber (Cenomanian) of Fouras/Bois-Vert, France. It is the oldest known record confirmed for the entire superfamily Cleroidea on the European continent. The fine state of preservation and the transparency of the amber matrix make it possible to determine certain morphological character states for the fossil and insert them into a character matrix of Trogossitidae genera to suggest an internal phylogenetic position for <i>C. vulloi</i>. The resulting tree reveals the basal position of <i>C. vulloi</i> within the lophocaterine clade and it is proposed that it may form an extinct branch of the Recent Decamerini. Some remarks on the palaeobiogeography of the Trogossitidae are also provided. Two other possible Trogossitidae from the Cretaceous amber (Albian) of Spain are also discussed and figured.http://zoobank.org/urn:lsid:zoobank.org:pub:66D7911E-E338-414B-B072-BAE0B0400201

title: Species-level phylogenetic revision of the Ordovician orthide brachiopod <i>Glyptorthis</i> from North America

description: Species of the orthide brachiopod genus <i>Glyptorthis</i> occur as common constituents of Late Ordovician benthic marine faunas, particularly in Laurentia. A phylogenetic analysis of 23 North American species of <i>Glyptorthis</i> was conducted to inform a systematic revision and ascertain evolutionary relationships amongst species. Both discrete and continuous characters, from which character states were determined using statistical methods, were utilized within a maximum parsimony approach. <i>Glyptorthis maquoketensis</i> is recognized as a distinct species of <i>Glyptorthis</i> rather than a subspecies of <i>G. insculpta</i>. <i>Glyptorthis virginica</i> is herein synonymized with <i>G. uniformis</i>. Several species of <i>Glyptorthis</i> became widely distributed via dispersal events during the evolution of the clade. The revised phylogenetic topology provides structure to interpret biogeographical patterns within the genus. For example, <i>Glyptorthis insculpta</i> participated in the Late Ordovician Richmondian Invasion into the Cincinnati Basin. The recovered phylogenetic topology suggests that <i>G. insculpta</i> may have invaded the Cincinnati Basin from a low latitude subtropical region of Laurentia, such as the American mid-Continent.

title: First cranial remains of <i>Cheirogaster richardi</i> (Testudines: Testudinidae) from the Late Miocene of Ecoparc de Can Mata (Vallès-Penedès Basin, NE Iberian Peninsula): taxonomic and phylogenetic implications

description: Although skulls of extinct Testudinidae are generally much scarcer than shell remains, when available they provide important data for resolving taxonomic and phylogenetic problems, as illustrated here by two well-preserved giant tortoise skulls from the early Vallesian (MN9, Late Miocene) of Ecoparc de Can Mata (ECM; els Hostalets de Pierola, Vallès-Penedès Basin, NE Iberian Peninsula). These specimens, referable to the extinct genus <i>Cheirogaster</i>, differ significantly from <i>C. bolivari</i> and are assigned to <i>C. richardi</i>, whose cranial morphology was previously unknown. This nominal taxon had been considered a junior subjective synonym of <i>C. bolivari</i>, due to a previous neotype designation for the former, based on shell remains, that did not meet the requirements of the <i>International Code of Zoological Nomenclature</i>. This designation is here considered invalid because it was based on material from a different geographical area, even though remains from the original type locality area were available. Given that the holotype of <i>C. richardi</i> (from the early Vallesian of els Hostalets de Pierola) has been destroyed, to clarify the taxonomic status of this taxon we here designate one of the two ECM skulls as the neotype of the species. On this basis, an emended diagnosis is provided, which leads us to conclude that two different species are recorded from the Iberian Miocene: <i>C. bolivari</i>, from the middle Aragonian of the inner Iberian basins; and <i>C. richardi</i>, from the latest Aragonian and Vallesian of the Vallès-Penedès Basin. Additional cranial material of <i>Cheirogaster</i> from inner Iberia would be required to clarify whether these species display distinct geographical distributions and/or different chronostratigraphical ranges. A cladistic analysis of Testudinidae based on cranial morphology supports a sister-taxon relationship between <i>Cheirogaster</i> and <i>Centrochelys</i>. Overall, our results highlight the significance of cranial morphology for attaining a better understanding of turtle taxonomy and phylogenetic relationships.
