Resumo: ABSTRACT: The discovery of new vertebrate fossil sites with skeletal remains in the Enciso Group of Igea (La Rioja) is showing the relevance of the area to study the palaeobiodiversity of Early Cretaceous vertebrate faunas from the Iberian Peninsula. At Peña Cárcena hill two sedimentary environments have been inferred: a mixed siliciclastic-carbonate lacustrine environment that is dominant at the outcrops, overlaid by a splay delta in an avulsion-belt. The vertebrate remains are especially abundant in the mixed siliciclastic-carbonate lacustrine deposits with two partially articulated skeletons (a theropod and a large-sized dinosaur), teeth and a fragment of a left maxilla of baryonychines, a pterosaur tooth that differs from those of Prejanopterus, a Goniopholis tooth, chelonian shell fragments that might belong to Camerochelys, a fairly complete lepisosteiform, teeth and dorsal fin spines of hybodontiforms. At the delta deposits, vertebrate fossils are rather scarce, with a single lepisosteiform skeleton and indeterminate bone fragments.

Na colina de Peña-Cárcena, tem-se inferido dois ambientes sedimentares: o predominante nos afloramentos corresponde a um ambiente lacustre, siliciclástico-carbonatado misto, que se encontra sobreposto por depósitos de transbordo deltaico em cinturão abandonado. Restos de vertebrados são abundantes nos depósitos lacustres, incluindo dois esqueletos parciais articulados (de um terópode e de outro dinossáurio de grande porte), dentes e um fragmento de maxila esquerda de barionicinos, um dente de pterossáurio distinto de Prejanopterus, um dente de Goniopholis, fragmentos da carapaça de quelónios que poderão pertencer a Camerochelys, um lepisosteiforme praticamente completo, dentes e espinhos de barbatanas de hybodontiformes. Fósseis de vertebrados são escassos nos depósitos deltaicos, com apenas um esqueleto de lepisosteiforme e fragmentos indeterminados.LNEG - Laboratório Nacional de Energia e GeologiaRepositório do LNEGIsasmendi, ErikNavarro-Lorbés, PabloLopez Horgue, Miguel AngelSáez-Benito, P.Viera, L.Torices, AngelicaPereda Suberbiola, Xabier2022-05-06T10:13:18Z2021-06-01T00:00:00Z2021-06-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10400.9/3838engIsasmendi, E...
