The Late Jurassic Lourinhã Formation is known for its abundant remains of dinosaurs, crocodylomorphs and other vertebrates. Among this record are nine localities that have produced either dinosaur embryos, eggs or eggshell fragments. Herein, we describe and identify the first crocodiloid morphotype eggs and eggshells from the Lourinhã Formation, from five occurrences. One clutch from Cambelas, ...

The newly recognized Konservat-Lagerstätte of Ettling (Bavaria), field site of the Jura-Museum Eichstätt (JME), is unique among Late Jurassic plattenkalk basins (Solnhofen region) in its abundant, extremely well preserved fossil vertebrates, almost exclusively fishes. We report actinopterygians (ginglymodins, pycnodontiforms, halecomorphs, aspidorynchiforms, "pholidophoriforms," teleosts); turt...

Plesiochelyidae are a major component of Late Jurassic shallow marine environments throughout Europe. However, the taxonomy of plesiochelyid turtles is rather confused. Over the years, many taxa have been synonymized with Plesiochelys etalloni, one of the first described species. However, the holotype of P. etalloni (and only specimen known from Lect, the type locality) was lost for more than 1...

Eclogites formed during the Eo-alpine metamorphic event are common within the ophiolitic unit of the Mulhacén complex, which forms part of the Betic Cordillera in southeastern Spain. A detailed study with cathodoluminescence (CL) images of zircon from these eclogites has revealed three types of domains, confirmed by some differences in their REE patterns and ages. There are a) igneous domains, ...

Cycle stratigraphic and magnetostratigraphic analyses of a -5000-m-thick composite section obtained by scientific coring in the Newark rift basin of eastern North America provide a high-resolution astronomically calibrated geomagnetic polarity timescale (GPTS) spanning over 30 m.y. of the Late Triassic and earliest Jurassic. Only normal polarity is found in -1000 m of interbedded volcanics and ...

reasonably diverse and fairly preserved palynoflora, dominated by land-derived palynomorphs (miospores) in association with minor marine entities, such as dinoflagellate cysts, foraminiferal test linings, and acritarchs, occur in surface samples of the hojedk formation, at the eshkeli stratigraphic section, north of kerman. spores with radiosymmetrical symmetry (trilete spores), bisaccate and m...

Reconstructing provenance in sandstones can be challenging, especially when the hinterland palaeogeology is unknown due to burial, diagenesis or weathering of original outcrops. As sedimentary processes alter distribution minerals depositional environment, use multiple methods reduces uncertainties, because, together, they account for depositionally-controlled textural and mineralogical re-dist...
