“…The deposits are interpreted as a low gradient lake margin that exposed/inundated large areas with slight changes in water level. Similar examples have been described in the Cenozoic deposits of the Duero and Tajo basins (Alonso-Zarza, 2003;Alonso-Zarza et al, 1992;Huerta and Armenteros, 2005;Huerta et al, 2011).…”

The Las Sereas site includes at least 14 ichnological outcrops along 5.6 km, in the Lara area, southwest Burgos Province. 67 ichnites of dinosaurs are documented at Las Sereas 7, identified as theropod and sauropod trackways occurring in shallow carbonates of lacustrine environment. Sauropod trackways have intermediate-gauge and low heteropody, and show different anatomical features to other tracks found in the ichnological record, especially in the disposition and orientation of pes digits. They are similar to Polyonyx from the Middle Jurassic of Portugal. However, since they do not preserve reliable manus data they are classified as aff. Polyonyx. The three sauropod trackways are related to the same kind of trackmaker. They differ from each other only in size, and gregarious behavior has not been detected. Analysis of these trackways reveals changes in travel direction even when there are few tracks in each sequence. At the Las Sereas 7 tracksite, the pace length (PL), width of the angulation pattern (WAP) and the WAP/PL ratio and depth analysis via photogrammetry show a direction change in two sauropod trackways. This tracksite and that at La Pedraja are unique in the Tithonian-Berriasian interval of the Iberian Peninsula that occur in a lacustrine environment, and could be indicate of the relationship between the diversity of Iberian, Tithonian-Berriasian sauropod tracks and sedimentary environments.Keywords: Dinosaurs, Sauropod tracks, Tithonian, Berriasian, Cameros Basin, Iberia Resumen El yacimiento de Las Sereas se compone de al menos 14 afloramientos icníticos que se localizan a lo largo de 5,6 Km de longitud en la comarca de Lara, en el sureste de la provincia de Burgos. En el afloramiento de Las Sereas 7 se han documentado 67 icnitas de dinosaurios, identificadas como terópodas y saurópodas, producidas en un ambiente lacustre carbonatado somero. Las rastros saurópodos son de anchura intermedia y heteropodia baja mostrando caracteres anatómicos diferentes a los encontrados en el registro icnológico conocido, en especial en lo referente a la disposición y orientación de los dedos del pie. La mayor semejanza de estas icnitas saurópodas se establece con Polyonyx del Jurásico Medio de Portugal, pero al carecer de datos fiables sobre la anatomía de las manos en Las Sereas, clasificamos estas icnitas de Burgos como aff. Polyonyx. Los tres rastros saurópodos de Burgos se atribuyen a un mismo icnopoyeta, diferenciándose entre sí sólo por el tamaño, y sin que se haya detectado un comportamiento gregario. En el estudio de estos rastros pueden recogerse datos que informen sobre trayectos con cambio de dirección, incluso cuando lo que se conserva es una serie relativamente corta de pasos. En Las Sereas 7 la combinación de los valores de varios parámetros -longitud de paso (PL), pauta de anchura de angulación (WAP) y relación WAP/PL -y el estudio de la profundidad de las icnitas por fotogrametría permiten interpretar un cambio de dirección en dos de los rastros saurópodos. Este yacimiento y el de La Pedraja...

“…These upward changes could be caused by a progressive decrease in accommodation (A) or an increase in sediment supply (S). An upward decrease in the A/S ratio would produce more amalgamated channel bodies and a decrease in the proportion of floodplain fines that were preserved between channel bodies as successive channels remove and rework the overbank deposits that lay between them (e.g., Huerta et al 2011;Wright and Marriott 1993).…”

There are numerous allocyclic and autocyclic factors which influence fluvial sandbody geometry. Unraveling the relative importance of such factors is challenging because fluvial systems can migrate and avulse across significant distances on the floodplain, so that collecting datasets that cover a large enough area with sufficient detail is difficult. This problem has been addressed by acquiring an oblique helicopter-mounted lidar survey over 16 km of exposed sections from Cretaceous coastalplain deposits cropping out in the Wasatch Plateau of east-central Utah. The exposures of the Blackhawk Formation occur in steep cliffs, which are continuous for several tens of kilometers, and have been previously inaccessible for study.The recorded lidar data were used to build detailed photorealistic models (virtual outcrops) from which quantitative dimensional data on fluvial architectural elements (mostly sandstone channel bodies) were collected. Those channelized bodies show significant variation in width and thickness. 26% of the sandbodies were identified as being multistory channel bodies, with a thickness of 9.1 m (± 4.67 m; 1 s) and a width of 142.6 m (± 180.7 m), which are significantly larger than the measured single-story sandbodies (5.9 m and 96.9 m, respectively). 50% of all sandbodies have aspect ratios smaller 13:1 and the highest values reach 78:1.The spatial constraint of the 397 fluvial sandbodies enabled the recognition of a series of vertical trends within the dataset. These trends include a subtle upward increase in width and thickness of both the mean and maximum values. This is coupled with a general upward decrease in the number of sandbodies and results in a broadly constant channel-to-overbank ratio. A clear correlation between wider channels with increased distance to the shoreline could also be documented.These observations can be explained by considering the entire Blackhawk Formation as the deposits of a large distributive fluvial system. In this model the key control on channel architecture is the distance to the shoreline, contrasting with previous interpretations of the Blackhawk depositional system in which the rate of accommodation creation in the coastal plain was thought to be the key control on channel geometry and stacking patterns.

“…However, a clear distinction between climatic and tectonic signals is difficult. In addition to tectonic and climatic determinations, fan evolution is influenced by processes such as catchment area evolution and autocyclic lobe switching (Fraser and DeCelles, 1992;Blair and McPherson, 1994;Huerta et al, 2011).…”

The deposits of the Upper Carboniferous to Lower Permian Zöbing Formation in Lower Austria have been studied by a wide range of sedimentological methods in several limited outcrops. Four facies associations were identified: (a) non-channelized finegrained deposits; (b) channelized sandstones, (c) non-channelized conglomerates, and (d) channelized conglomerates. Non-channelized fine-grained sediments are interpreted as deposits in shallow, semi-permanent pools on floodplains. Channelized sandstones are associated with fluvial processes and mostly represent crevasse channels cut into the floodplains. Channelized conglomerates originated from coarse-grained confined and hyperconcentrated flows. Non-channelized conglomerates are interpreted as sediments of alluvial fan and alluvial plain systems. A terminal fluvial system developed under a semi-arid to arid climatic regime is supposed to be the depositional environment of the Zöbing Formation.The detritus was mostly derived from primary sources formed by crystalline rocks. The proportion of metamorphites (particularly metapelitic rocks, such as mica schists, paragneisses, felsitic granulites) was predominant along with acidic magmatic and volcanic rocks. The source area predominantly can be located in the Moldanubian unit. Rapid physical erosion, redeposition and subordinately also chemical weathering are all supposed in the source area. The general provenance evolution of the entire Zöbing Formation shows local/adjacent sources in the basal parts whereas a wider provenance and variations in the primary and recycled detritus are assumed for the younger parts of the succession.________________________________________________________
