  • A New Plesiosaur from the Lower Jurassic of Portugal and the Early Radiation of Plesiosauroidea
    A new plesiosaur from the Lower Jurassic of Portugal and the early radiation of Plesiosauroidea EDUARDO PUÉRTOLAS-PASCUAL, MIGUEL MARX, OCTÁVIO MATEUS, ANDRÉ SALEIRO, ALEXANDRA E. FERNANDES, JOÃO MARINHEIRO, CARLA TOMÁS, and SIMÃO MATEUS Puértolas-Pascual, E., Marx, M., Mateus, O., Saleiro, A., Fernandes, A.E., Marinheiro, J., Tomás, C. and Mateus, S. 2021. A new plesiosaur from the Lower Jurassic of Portugal and the early radiation of Plesiosauroidea. Acta Palaeontologica Polonica 66 (2): 369–388. A new plesiosaur partial skeleton, comprising most of the trunk and including axial, limb, and girdle bones, was collected in the lower Sinemurian (Coimbra Formation) of Praia da Concha, near São Pedro de Moel in central west Portugal. The specimen represents a new genus and species, Plesiopharos moelensis gen. et sp. nov. Phylogenetic analysis places this taxon at the base of Plesiosauroidea. Its position is based on this exclusive combination of characters: presence of a straight preaxial margin of the radius; transverse processes of mid-dorsal vertebrae horizontally oriented; ilium with sub-circular cross section of the shaft and subequal anteroposterior expansion of the dorsal blade; straight proximal end of the humerus; and ventral surface of the humerus with an anteroposteriorly long shallow groove between the epipodial facets. In addition, the new taxon has the following autapomorphies: iliac blade with less expanded, rounded and convex anterior flank; highly developed ischial facet of the ilium; apex of the neural spine of the first pectoral vertebra inclined posterodorsally with a small rounded tip. This taxon represents the most complete and the oldest plesiosaur species in the Iberian Peninsula.

The preserved teeth display distinctive features such as a very long, robust and coarsely Lower jurassic infolded roots; as well as low, labio-lingually compressed, large triangular crowns with carinae. Dental features south Pangea are consistent with those of the genus Temnodontosaurus, previously known in the Lower Jurassic of Europe. This Paleobiogeography find represent the first record of a temnodontosaurid ichthyosaur in the southern hemisphere, reinforcing a pattern of faunal interchange between the northern Tethys and southern Panthalassa, prior to the separation of Palabras clave: Laurasia and Gondwana, and before the full establishment of the Caribbean Seway.

ISSN 2533-4050 (print), ISSN 2533-4069 (on-line). Abstract: Substantial numbers of the nautilid Cenoceras occur in a stratigraphically limited horizon within the upper part of the Lower Jurassic (Sinemurian Stage) Blue Lias Formation at Watchet on the West Somerset Coast (United Kingdom). Individual nautilid conchs are associated with clusters of encrusting organisms (sclerobionts) forming ‘islands’ that may have been raised slightly above the surrounding substrate. Despite the relatively large numbers of nautilid conchs involved, detailed investigation of their preservation suggests that their accumulation reflects a reduction in sedimentation rates rather than an influx of empty conches or moribund animals. Throughout those horizons in which nautilids are present in relative abundance, the remains of ammonites are subordinate or rare. The reason for this unclear, and preferential dissolution of ammonite conchs during their burial does seem to provide a satisfactory solution to the problem.

En el presente trabajo se reporta por primera vez una fauna de amonites (Paltechioceras cf. mexicanum, P. rothpletzi, Ortechioceras incaguasiense, Coroniceras? (Metophioceras) aff. conybeari auct., Phylloceras sp., Sulciferites? cf. stenorhynchus) e isocrínidos bentónicos (Isocrinidae) y pseudoplanctónicos (Pentacrinitidae). Estos últimos representan nuevos registros para sedimentos sinemurianos de México. Se consideran los supuestos hábitos de vida para las familias a las que pertenecen las especies de amonites, como dato de referencia sobre el ambiente de depósito. En este afloramiento también se encuentra el bivalvo Posidontis semiplicata y un gasterópodo no identificado. Hay tres tipos de asociaciones fósiles que se encuentran repetidamente en las capas del afloramiento Temapá, perteneciente a la Formación Despí, de tal forma que es posible reconocerlas (1) por la diferencia de diámetro de los amonites que las componen; (2) por la diferente composición faunística entre ellas, que se demuestra con la aplicación del índice de Simpson; y (3) por el grado de fragmentación de las conchas.

  • The Late Triassic and Early Jurassic Succession at Southam Cement Works, Warwickshire Jonathan D
    The late Triassic and early Jurassic succession at Southam Cement Works, Warwickshire Jonathan D. Radley Abstract. Southam Cement Works Quarry, Long Itchington, exposes beds ranging from the Cotham Member of the late Triassic Lilstock Formation up into the Rugby Limestone Member of the early Jurassic Blue Lias Formation. The lithologies and fauna are described and interpreted in the context of Triassic and Jurassic palaeoenvironmental change. Warwickshire’s Jurassic outcrop is dominated by a investigated by Weedon (1986) and Wignall and broad low-lying terrain formed by argillaceous rocks Hallam (1991). Aspects of the palaeontology and of the early Jurassic (Hettangian up to ichnology have been documented by Clements Pliensbachian) Blue Lias and Charmouth Mudstone (1975), Gilliland (1992) and Swift and Martill formations. The Charmouth Mudstone Formation (1999). Jones and Gould (1999) featured Long is poorly exposed, however the upper part of the Itchington material in their important study of Blue Lias Formation (Rugby Limestone Member; oyster (Gryphaea) growth and evolution. Ambrose, 2001) has been extensively quarried for Additionally, the site has been mentioned by several the cement industry. Largely inaccessible sections other workers including Nuttall (1916), Arkell occur in several disused pits, as at Rugby and near (1947) and Hallam (1968). Rocks and fossils from Harbury. the site are held in the collections of Warwickshire Currently (2002) the only working quarry is at Museum. Long Itchington, [NGR SP420630] 10 km E.S.E. of Leamington Spa (Fig. 1). Here, the deep, extensive Lilstock Formation (Langport Member) excavation at Southam Cement Works exposes early Jurassic mudstones and limestones of the Blue Lias The main quarry floor is a broadly planar (but in Formation (Saltford Shale and Rugby Limestone places hummocky) iron-stained surface, marking the members; Hettangian up to Sinemurian; liasicus up eroded top of the Langport Member.

  • Mary Anning: Fossil Collector, Paleontologist, and Heroic Spirit
    Journal of Geek Studies jgeekstudies.org Mary Anning: fossil collector, paleontologist, and heroic spirit Rodrigo B. Salvador Museum of New Zealand Te Papa Tongarewa, Wellington, New Zealand. Email: [email protected] there is an ongoing movement to build a statue for her. Secondly, there is a movie called Ammonite (Lionsgate, 2020) that is a dramatic retelling of her story. While most paleontologists are happily supportive of the statue-building campaign, the community (and critics) was divided re- garding the movie, mostly due to Anning’s portrayal as a lesbian.2 Yep, people still get angry with those sorts of things. Anyway, I will not discuss the movie here, because I’m neither entitled to nor interested in dis- cussing dead scientists’ sexuality. Besides, I haven’t watched it. I think, however, that I am in a good po- sition to talk about another representation of Mary Anning in pop culture. As possibly the only – or one of the very few3 – profes- sional paleontologists invested in the Fate franchise,4 I dedicate this article to discuss Anning’s incarnation in Fate/Grand Order.
