In the previously known sites the following new material was discovered: at Piau, a sauropod trackway; at Serrote do Letreiro a new theropod trackway; at Riacho do Cazé, some sauropod and theropod tracks; at Mãe d’Água, new sauropod, theropod and ornithopods footprints. At Fazenda Paraíso new theropod and sauropod tracks were discov- ered and a new map of the main rocky pavement including theropod tracks is provided here. The farms at Saguim de Cima, Várzea da Jurema, Tabuleiro, Catolé da Piedade (WNW of Sousa, in the Sousa Formation) and at Pau d’Arco (SE of Sousa, in the Piranhas Formation) were explored without results. RIASSUNTO - Nuove piste di dinosauri nel bacino di Sousa (Cretaceo inferiore, Paraíba, Brasile) - Durante la nostra 30ª spedizione ai bacini del Rio do Peixe (Cretaceo inferiore; Paraíba, Brasile nord orientale) sono stati sco- perti i seguenti nuovi siti con piste di dinosauri: Floresta dos Borba (teropodi, sauropodi, ornitopodi), Lagoa do Forno (teropodi, sauropodi), Lagoa do Forno II (un teropodo), Várzea dos Ramos II (teropodi), Várzea dos Ramos III (tero- podi). -
Gymnosperm Foliage from the Upper Triassic of Lunz, Lower Austria: an Annotated Check List and Identification Key

The historical outcrops (mainly coal mines) are no longer accessible, but showy fossils can still be collected from natural exposures around the town of Lunz-am-See and from several of the old spoil tips. This paper presents an annotated check list with characterisations of all currently recognised gymnosperm foliage taxa in the Lunz flora. The descriptions are exemplified by illustrations of typical specimens and diagnostic features of the leaf morphology and epidermal anatomy. Moreover, a simple identification key for the taxa based on macromorphological features is provided that facilitates identification of newly collected specimens. 1. Introduction The Carnian (Late Triassic) flora from Lunz in Lo- ments (i.e. reproductive structures) among the fossils wer Austria is one of only a few well-preserved flo- (see e.g., Krasser, 1917, 1919; Kräusel, 1948, 1949, ras from the Alpine Triassic (Cleal, 1993; Dobruskina, 1953; Pott et al., 2010), the most striking feature of 1998). -

E-mail: [email protected] Abstract – Based on cranial and jaw elements, the presence of Albanerpeton pannonicum species (Allocaudata: Albanerpetontidae) was noticed from the late Pliocene Csarnóta 3 locality (Villány Hills). Since it is considered a poor fossil site, it had not been suffi ciently studied. Th ese fossils represent the geologically youngest record of the species from Hungary. Th ough, the Csarnóta 3 albanerpetontid assemblage is small the bones are well preserved, and all are informative on spe- cies or at least on genus level. Th e red coloured bone-bearing deposits and the preservation quality of bones are very similar to the uppermost strata (4–1) of the Csarnóta 2 palaeovertebrate locality. Th e study of small mammal fauna also suggests this correlation, as well as explains the age of the site. Th e studied vertebrate fauna forms a transition between the woodland and steppe wildlife.

The tracks are preserved in the Helvetiafjellet For- mation (Barremian). A sedimentological characterization of the site indicates that the tracks formed on a beach/margin of a lake or interdistributary bay, and were preserved by flooding. In addition to the two imprints already known from the site, we describe at least 34 additional, pre- viously unrecognized pes and manus prints, including one trackway. Two pes morphotypes and one manus morphotype are recognized. Given the range of morphological variation and the pres- ence of manus tracks, we reinterpret all the prints as being from an ornithopod rather than a thero- pod, as previously described. We assign the smaller (morphotype A, pes; morphotype B, manus) to Caririchnium billsarjeanti. The larger (morphotype C, pes) track is assigned to Caririchnium sp., differing in size and interdigital angle from the two described ichnospecies C. burreyi and C. -

Here we report on the composition of the Cliffs of Insanity (COI) microvertebrate locality, a newly sampled site containing perhaps one of the densest concentrations of microvertebrate fossils yet discovered in the Mussentuchit Member. The COI locality preserves osteichthyan, lissamphibian, testudinatan, mesoeucrocodylian, dinosaurian, metatherian, and trace fossil remains and is among the most taxonomically rich microvertebrate localities in the Mussentuchit Submitted 30 May 2018 fi fi Accepted 8 October 2018 Member.

Early Cretaceous) Wessex Formation of the Isle of Wight, Southern England
A new albanerpetontid amphibian from the Barremian (Early Cretaceous) Wessex Formation of the Isle of Wight, southern England STEVEN C. SWEETMAN and JAMES D. GARDNER Sweetman, S.C. and Gardner, J.D. 2013. A new albanerpetontid amphibian from the Barremian (Early Cretaceous) Wes− sex Formation of the Isle of Wight, southern England. Acta Palaeontologica Polonica 58 (2): 295–324. A new albanerpetontid, Wesserpeton evansae gen. et sp. nov., from the Early Cretaceous (Barremian) Wessex Formation of the Isle of Wight, southern England, is described. Wesserpeton is established on the basis of a unique combination of primitive and derived characters relating to the frontals and jaws which render it distinct from currently recognized albanerpetontid genera: Albanerpeton (Late Cretaceous to Pliocene of Europe, Early Cretaceous to Paleocene of North America and Late Cretaceous of Asia); Celtedens (Late Jurassic to Early Cretaceous of Europe); and Anoualerpeton (Middle Jurassic of Europe and Early Cretaceous of North Africa). Although Wesserpeton exhibits considerable intraspecific variation in characters pertaining to the jaws and, to a lesser extent, frontals, the new taxon differs from Celtedens in the shape of the internasal process and gross morphology of the frontals in dorsal or ventral view. It differs from Anoualerpeton in the lack of pronounced heterodonty of dentary and maxillary teeth; and in the more medial loca− tion and direction of opening of the suprapalatal pit. The new taxon cannot be referred to Albanerpeton on the basis of the morphology of the frontals. Wesserpeton currently represents the youngest record of Albanerpetontidae in Britain.

(Orthoptera) and Their Phylogenetic Implications Within Tetrigoidea
Mitochondrial genomes of eight Scelimeninae species (Orthoptera) and their phylogenetic implications within Tetrigoidea Ran Li1, Xiaoli Ying1, Weian Deng2, Wantao Rong2 and Xiaodong Li2 1 College of Life Sciences, Nanjing Normal University, Nanjing, China 2 School of Chemistry and Bioengineering, Hechi University, Yizhou, China ABSTRACT Scelimeninae is a key member of the pygmy grasshopper community, and an important ecological indicator. No mitochondrial genomes of Scelimeninae have been reported to date, and the monophyly of Scelimeninae and its phylogenetic relationship within Tetrigidae is still unclear. We sequenced and analyzed eight nearly complete mitochondrial genomes representing eight genera of Scelimeninae. These mitogenomes ranged in size from 13,112 to 16,380 bp and the order of tRNA genes between COII and ATP8 was reversed compared with the ancestral order of insects. The protein-coding genes (PCGs) of tetrigid species mainly with the typical ATN codons and most terminated with complete (TAA or TAG) stop codons. Analyses of pairwise genetic distances showed that ATP8 was the least conserved gene within Tetrigidae, while COI was the most conserved. The longest intergenic spacer (IGS) region in the mitogenomes was always found between tRNASer(UCN) and ND1. Additionally, tandem repeat units were identified in the longest IGS of three mitogenomes. Maximum likelihood (ML) and Bayesian Inference (BI) analyses based on the two datasets supported the monophyly of Tetriginae. Scelimeninae was classified as a non-monophyletic subfamily. -
A New Genus and Species of Basal Salamanders from the Middle Jurassic of Western Siberia, Russia P.P
Proceedings of the Zoological Institute RAS Vol. 315, No. 2, 2011, рр. 167–175 УДК 57.072:551.762.2 A NEW GENUS AND SPECIES OF BASAL SALAMANDERS FROM THE MIDDLE JURASSIC OF WESTERN SIBERIA, RUSSIA P.P. Skutschas1* and S.A. Krasnolutskii2 1Saint Petersburg State University, Universitetskaya Emb. 7/9, 199034 Saint Petersburg, Russia; e-mail: [email protected] 2Sharypovo Regional Museum, 2nd microrayon 10, Sharypovo, 662311 Krasnoyarsk Territory, Russia; e-mail: [email protected] ABSTRACT A new basal stem salamander, Urupia monstrosa gen. et sp. nov., is described based on an atlantal centrum (holotype), fragments of trunk vertebrae, and some associated elements (fragmentary dentaries and a femur) from the Middle Jurassic (Bathonian) Itat Formation of Krasnoyarsk Territory in Western Siberia, Russia. The new taxon is characterized by the following combination of characters: lack of the spinal nerve foramina in the atlas, presence atlantal transverse processes and a deep depression on the ventral surface of the atlas; lateral surface of anterior part of the dentary is sculptured by oval and rounded pits; very short diaphyseal part of femur. The absence of intercotylar tubercle on the atlas and presence of atlantal transverse processes support for neotenic nature of Urupia monstrosa gen. et sp. nov. Large size, presence of sculpture on vertebrae, and the absence of spinal nerve foramina in the atlas suggest that Urupia monstrosa gen. et sp. nov. is a stem group salamander. The phylogenetic relationships of Urupia monstrosa gen. et sp. nov. with other stem group salamanders cannot be established on the available material.
