title: †<i>Tugenchromis pickfordi</i>, gen. et sp. nov., from the upper Miocene—a stem-group cichlid of the ‘East African Radiation’

description: The highly diverse tropical freshwater fish family Cichlidae is sparsely represented in the fossil record. Here we describe the new cichlid †<i>Tugenchromis pickfordi</i>, gen. et sp. nov., from the Upper Miocene (9–10 Ma) of central Kenya. The new taxon possesses a unique combination of characters, including six lateral line foramina on the lacrimal, three lateral line segments, cycloid scales, and a low number of vertebrae (29), dorsal fin spines (13), and dorsal soft rays (9). Its lacrimal morphology and tripartite lateral line suggest an affinity with the present-day Lake Tanganyika tribes Ectodini and Limnochromini, and thus with members of the ‘East African Radiation’ among the African cichlids. To further elucidate the relationships of †<i>T. pickfordi</i>, we used a comprehensive comparative data set comprising meristic data from all present-day tribes of the ‘East African Radiation.’ Principal coordinates analyses support links between the fossil and Ectodini + Limnochromini, and additionally with modern Haplochromini. We conclude that †<i>T. pickfordi</i> could be an extinct lineage within the ‘most ancient Tanganyika tribes,’ or a stem lineage of the ‘ancient Tanganyika mouthbrooders.’ A direct relationship to the Haplochromini is unlikely because its members do not exhibit the derived characteristics of the lacrimal as seen in †<i>T. pickfordi</i>. Because Lake Tanganyika is located in the western branch of the East African Rift System, †<i>T. pickfordi</i> from the eastern branch supports the ‘melting-pot Tanganyika hypothesis,’ which posits that the cichlids of modern Lake Tanganyika are derived from riverine lineages that had already diversified prior to the lake formation. http://zoobank.org/urn:lsid:zoobank.org:pub:37520070-99B3-463C-B8E6-9452D1F62722 SUPPLEMENTAL DATA—Supplemental materials are available for this article for free at www.tandfonline.com/UJVP.

title: <i>Bonapartesaurus rionegrensis</i>, a new hadrosaurine dinosaur from South America: implications for phylogenetic and biogeographic relations with North America

description: The Gondwanan hadrosaurid dinosaur record is relatively poorly known and very complicated. A new hadrosaurid, <i>Bonapartesaurus rionegrensis</i>, gen. et sp. nov., from the late Campanian–early Maastrichtian of the Salitral Moreno site, Argentina, is characterized by the following combination of characters: the ratio between the height of the neural spines and that of the centrum of the sacral vertebrae greater than 3.5; neural spines of the anterior section of the caudal vertebrae extremely long and evenly expanding distally; a preacetabular process of the ilium slightly deflected ventrally, with the angle greater than 150°; the ratio between the maximum dorsoventral depth of the posterior end of the preacetabular process and the dorsoventral distance from the pubic peduncle to the dorsal margin of the ilium less than 0.50; the ratio between the dorsoventral height and anteroposterior length of the iliac blade 0.8 or greater; asymmetrical lateral profile of the supraacetabular process; the posterior portion of the postacetabular process markedly thicker mediolaterally as a result of the dorsomedial twist of the postacetabular process; an anteriorly expanded cnemial crest restricted to the proximal end of the tibia; and articular surface of the astragalus for the internal malleolus of the tibia moderately expanded medially, articulating with only part of the ventral surface of the tibial internal malleolus. Our phylogenetic analysis indicates that <i>Bonapartesaurus</i> is located within the Tribe Saurolophini. Paleobiogeographically, its presence suggests at least two saurolophine dispersal events from North America, one toward South America and another toward Asia, no later than the late Campanian. http://zoobank.org/urn:lsid:zoobank.org:pub:1ADEDB71-1FD6-4081-915D-6C73D8389408 SUPPLEMENTAL DATA—Supplemental materials are available for this article for free at www.tandfonline.com/UJVP Citation for this article: Cruzado-Caballero, P., and J.

title: A morphological study of the first known piscivorous enantiornithine bird from the Early Cretaceous of China

description: A fish-eating enantiornithine bird with a gastric pellet composed of fish bones has recently been reported from the Lower Cretaceous Jiufotang Formation of Liaoning Province, northeastern China. Along with other discoveries, this specimen reveals that distinct features of modern avian digestive system were well established in those early birds. On the basis of a detailed anatomical study presented here, we show that this fish-eating enantiornithine bird represents a new taxon, <i>Piscivorenantiornis inusitatus</i>, gen. et sp. nov. The well-preserved elements of the skull, neck, sternum, and pelvis further enrich our understanding of the morphological diversity in early enantiornithines. Most notably, the cranial articular facet of the caudal cervical vertebra is dorsoventrally concave and mediolaterally convex, a feature otherwise unknown among other birds and with unclear functional significance. http://zoobank.org/urn:lsid:zoobank.org:pub:C87B5BE9-B378-414E-81F3-7FD4162795C4 SUPPLEMENTAL DATA—Supplemental materials are available for this article for free at www.tandfonline.com/UJVP Citation for this article: Wang, M., and Z.

title: <i>Cyclotosaurus naraserluki,</i> sp. nov., a new Late Triassic cyclotosaurid (Amphibia, Temnospondyli) from the Fleming Fjord Formation of the Jameson Land Basin (East Greenland)

description: <i>Cyclotosaurus naraserluki</i>, sp. nov., is a new Late Triassic capitosaurid amphibian from lacustrine deposits in the Fleming Fjord Formation of the Jameson Land Basin in Greenland. It is based on a fairly complete and well-preserved skull associated with two vertebral intercentra. Previously reported as <i>Cyclotosaurus</i> cf. <i>posthumus</i>, <i>C. naraserluki</i> is unique among cyclotosaurs for having the postorbitals embaying the supratemporals posteromedially. The anterior palatal vacuity presents an autapomorphic complete subdivision by a wide medial premaxillary-vomerine bony connection. The parasphenoid projects between the pterygoids and the exoccipitals, preventing a suture between the two, a primitive condition shared with Rhinesuchidae, <i>Eryosuchus</i>, and <i>Kupferzellia</i>. Within <i>Cyclotosaurus</i>, the Greenlandic skull has a distinctive combination of circular choanae (shared with <i>C. ebrachensis</i>, <i>C. posthumus</i>, and <i>C. robustus</i>) and a convex posteromedial margin of the tabulars (also present in <i>C. ebrachensis</i> and <i>C. intermedius</i>). A phylogenetic analysis indicates that <i>C. naraserluki</i> is the sister taxon of the middle Norian <i>C. mordax</i> from southern Germany, with which it shares a pair of premaxillary foramina. <i>Cyclotosaurus</i> is one of the most successful and diverse genera of Late Triassic temnospondyls, with at least eight species reported from middle Carnian to late Norian. <i>Cyclotosaurus naraserluki</i> is the largest amphibian ever reported from Greenland and one of the Late Triassic vertebrates with the highest northern paleolatitude currently known. http://zoobank.org/urn:lsid:zoobank.org:pub:43AAA541-031C-4EE1-B819-4846EBBD1BBB SUPPLEMENTAL DATA—Supplemental materials are available for this article for free at www.tandfonline.com/UJVP Citation for this article: Marzola, M., O.

title: A new specimen of <i>Lariosaurus xingyiensis</i> (Reptilia, Sauropterygia) from the Ladinian (Middle Triassic) Zhuganpo Member, Falang Formation, Guizhou, China

description: A new specimen of <i>Lariosaurus xingyiensis</i> is described and provides new information on the dermal palate of the skull and the postcranial skeleton. Based on a comprehensive comparison with the holotype specimen, an amended diagnosis of <i>L. xingyiensis</i> is given on the basis of the following features: a medium-sized species of <i>Lariosaurus</i> with jugal absent, longitudinal diameter of upper temporal fenestra about 1.7 times longitudinal diameter of orbit, retroarticular process elongate, clavicles without anterolaterally expanded corners, posterior scapular process (blade) slender and elongate, humerus distinctly shorter than femur, and dorsal process of ilium with distinct tubercular ornamentation. Two phylogenetic analyses of Nothosauridae demonstrate that <i>Nothosaurus</i> as previously conceived is not monophyletic whereas <i>Lariosaurus</i> is a monophylum. Three species previously referred to <i>Nothosaurus</i> are more closely related to <i>Lariosaurus</i> and are hereby reassigned to <i>Lariosaurus</i>, namely, <i>L. juvenilis, L. youngi</i>, and <i>L. winkelhorsti</i>.

title: Redescription of <i>Szelepis</i> Liu, 1981 (Placodermi, Arthrodira), from the Lower Devonian of China

description: The skull roof of the species <i>Szelepis yunnanensis</i> (Liu, 1979) from the Early Devonian of Yunnan is redescribed, as well as other <i>Szelepis</i> material previously published. It appears that only the holotype of <i>S. yunnanensis</i> can be confidently assigned to this genus. The fusion of the preorbital plates into one plate strongly suggests the assignment of <i>Szelepis yunnanensis</i> to the monophyletic family Actinolepididae Gross, 1940, sensu stricto (comprising <i>Actinolepis</i> Agassiz, 1884, and <i>Bollandaspis</i> Schmidt, 1979). This is confirmed by a phylogenetic analysis. Hence, <i>Szelepis</i> constitutes the most ancient occurrence of the family but not the sister group to the remaining members.
