“…This trace is also a useful climatic indicator, occurring in wet, monsoonal, lacustrine, and wet portions of dry seasonal climate deposits (Hasiotis 2002). In Hoover Quarry material, both examples of Scoyenia gracilis occur in conjunction with desiccation cracks, indicating a periodically emergent environment.…”

“…These trace fossils have been interpreted as feeding and/ or domichnial traces of coleopteran (beetle) larvae, (Hasiotis 2002); decapod crustaceans (crayfish burrows), (GierlowskiKordesch 1985;Olsen 1988); and arthropods of unknown affinity . Fossil beetle eleytra (wing covers) have been found in siltstone horizons of the Portland Formation, and beetle larvae of the species Mormolucoides articulates have been found in rocks of the approximately coeval Turners Falls Formation (Lull 1953;Olsen 1988;McDonald 1992 ReMARKS: Simple tubular vertical burrows occur in both marine and continental deposits.…”

Jurassic sandstones of the Hartford Basin are well known for their dinosaur trackways, but few studies have characterized their invertebrate ichnofaunas. A notable Portland Formation exposure in this area is the Hoover Quarry in East Longmeadow, Massachusetts, where vertebrate skeletal material (the type specimen of the crocodilian Stegomosuchus longipes) occurs in association with a diverse ichnofauna. Hoover Quarry ichnogenera include Eubrontes cf. gracilis, Planolites beverleyensis, Planolites montanus, probable Scoyenia burrows, and Skolithos isp. Also preserved at the site is Palaeophycus tortuosus, a sinusoidal burrow that had been previously synonymized with Palaeophycus tubularis. A probable Skolithos burrow termination with an unusual pattern of scratches also occurs, along with several problematic stellate structures. At this site, primary sedimentary structures on trace bearing surfaces are consistent with deposition in a shallow aquatic environment that was periodically emergent. Viewed in the context of nearby sections of the Portland Formation, Hoover Quarry exposures could have been deposited in fluvial, ephemeral lacustrine, or playa environments. Traces in the Hoover Quarry indicate Scoyenia-Skolithos-composite ichnofacies, elements of which are commonly produced in continental firmground environments. RÉSUMÉLes grès du Jurassique dans le bassin de Hartford sont reconnus pour la présence d'empreintes de dinosaures. Mais peu d'études ont permis de caractériser l'ichnofaune invertébrée qu'on peut également y observer. Un affleurement notable de la Formation Portland dans la région est présent dans la carrière Hoover, à East Longmeadow, au Massachusetts, où des matériaux de squelettes de vertébrés (le spécimen type du crocodilien Stegomosuchus longipes) et une ichnofaune diversifiée sont présents. L'ichnofaune de la carrière Hoover comprend les espèces comme Eubrontes cf. gracilis, Planolites beverleyensis, Planolites montanus, vraisemblablement des terriers de Scoyenia, et Skolithos. Il y a également sur le site l'espèce Palaeophycus tortuosus, un terrier sinusoïdal qui a déjà été nommé Palaeophycus tubularis. L'extrémité d'un terrier de l'espèce probable Skolithos accompagnée d'une série inusitée de stries ou d'éraflures est en outre présente, tout comme plusieurs structures étoilées dont l'origine demeure mystérieuse. Sur le site, des structures primaires sur des surfaces marquées de traces correspondraient à une sédimentation dans un milieu aquatique peu profond qui a émergé à intervalles périodiques. Considéré dans le contexte des sections de la Formation Portland, situées à proximité, le dépôt des affleurements de la carrière Hoover pourrait être survenu dans un milieu fluvial, lacustre éphémère ou en présence d'un lac temporaire. Les traces relevées dans la carrière Hoover indiquent la présence d'un ichnofaciès composite de type Scoyenia-Skolithos, dont les éléments sont couramment produits dans un milieu de sol continental à cohésion moyenne.[Traduit par la redaction]

“…The interdune element probably represents inter dune flats between aeolian dunes. These surfaces were close to with the capillary fringe of the water table (Mountney, 2006), where colonization by root structures and bioturbation are com mon (Kocurek, 1981;Loope, 1988;Hasiotis, 2002).…”

The Permian-Triassic transition (P-T) was marked by important geochemical perturbations and the largest known life crisis. Consequences of this event, as oxygen-depleted conditions and the unusual behavior of the carbon cycle, were prolonged during the Early Triassic interval delaying the recovery of life in both ter restrial and marine ecosystems. Studies on Lower Triassic sediments of continental origin, as in the case of Western Europe, are especially problematic due to the scarcity of fossils and absence of precise dating. The The Cafiizar Fm. has been subdivided into six members (A-F) separated by seven (1-7) major bounding surfaces (MBS). These surfaces are well recognized laterally over hundred of km and they represent 10 4 _10 5 My. MBS-5 is considered to be of late Spathian age and it is a clear indication of tectonic activity, represented by a mild unconformity. This event represents a change in the sedimentary characteristics (reactivation) of the unit and from here to the top of the unit are found the first signals of biotic recovery, represented by tetrapod footprints, plants, roots and bioturbation. All of these characteristics and the esti mated age represented by the MBS-5 event permit this surface to be related to the coeval Hardegsen un conformity of Central-Western Europe. These first signals of biotic recovery can thus be related to an increased oxygen supply due to the new created paleogeographical corridors in the context of this tectonic activity. These biotic signals occurred 5 My after the Permian-Triassic limit crisis; a similar delay as oc curred in other coeval and neigh boring basins.

“…Gibert and Sáez (2009) considered the shorebird ichnofacies to be a subset of the Scoyenia ichnofacies (an ichnosubfacies sensu Melchor et al, 2006) that characterizes the subaerial part of low-energy shore areas. On the other hand, the presence of Cochlichnus in a non-marine setting is typical of the Mermia ichnofacies and suggests a low energy perennial freshwater environment (Hasiotis, 2002;Buatois and Mángano, 2002). The occurrence of characteristic ichnotaxa of more than one ichnofacies in a single ichnofauna, as the occurrence in Liédena deposits, could be interpreted as a consequence of the trace-fossil producers being environmentally tolerant animals that could inhabit and behave similarly in either setting.…”

Fossil associations from the middle and upper Eocene (Bartonian and Priabonian) sedimentary succession of the Pamplona Basin are described. This succession was accumulated in the western part of the South Pyrenean peripheral foreland basin and extends from deep-marine turbiditic (Ezkaba Sandstone Formation) to deltaic (Pamplona Marl, Ardanatz Sandstone and Ilundain Marl formations) and marginal marine deposits (Gendulain Formation). The micropalaeontological content is high. It is dominated by foraminifera, and common ostracods and other microfossils are also present. The fossil ichnoasssemblages include at least 23 ichnogenera and 28 ichnospecies indicative of Nereites, Cruziana, and ?Scoyenia-Mermia ichnofacies. Body macrofossils of about 80 taxa corresponding to macroforaminifera, sponges, corals, bryozoans, brachiopods, annelids, molluscs, arthropods, echinoderms and vertebrates have been identified. Both the number of ichnotaxa and of species (e. g. bryozoans, molluscs and condrichthyans) may be considerably higher. Body fossil assemblages are comparable to those from the Eocene of the Nord Pyrenean area (Basque Coast), and also to those from the Eocene of the west-central and eastern part of South Pyrenean area (Aragon and Catalonia). At the European scale, the molluscs assemblages seem endemic from the Pyrenean area, although several Tethyan (Italy and Alps) and Northern elements (Paris Basin and Normandy) have been recorded. Palaeontological data of studied sedimentary units fit well with the shallowing process that throughout the middle and late Eocene occurs in the area, according to the sedimentological and stratigraphical data.Se describen las asociaciones fósiles del Eoceno medio y superior (Bartoniense y Priaboniense) de la sucesión sedimentaria de la Cuenca de Pamplona. Esta sucesión se acumuló en la parte oeste de la Cuenca de antepaís periférica surpirenaica y comprende desde turbiditas marinas profundas (Formación Areniscas de Ezkaba) hasta depósitos deltaicos (Formaciones Margas de Pamplona, Areniscas de Ardanatz y Margas de Ilundain) y marinos marginales (Formación Gendulain). El contenido micropaleontológico es alto y está dominado por los foraminíferos. Los fósiles de ostrácodos y otros organismos son también abundantes. Las asociaciones de icnofósiles incluyen al menos 23 icnogéneros y 28 ichnoespecies, indicativas de las icnofacies de Nereites, Cruziana, y ?Scoyenia-Mermia. Se han identificado fósiles corporales de unos 80 taxones, correspondientes a macroforaminíferos, esponjas, corales, briozoos, braquiópodos, anélidos, moluscos, artrópodos, equinodermos y vertebrados. El número de icnotaxones y de especies (p. e. briozoos, moluscos gasterópodos, bivalvos y peces condríctios) puede ser considerablemente mayor. Las asociaciones de fósiles corporales son comparables a las del Eoceno del Área norpirenaica (Costa vasca) y de las partes central y este del Área surpirenaica (Aragón y Cataluña). A escala europea, la asociación de moluscos parece endémica del Área pirenaica,...
