A basal tyrannosauroid dinosaur from the Late Jurassic of China
Nature, 2006The tyrannosauroid fossil record is mainly restricted to Cretaceous sediments of Laurasia, although some very fragmentary Jurassic specimens have been referred to this group. Here we report a new basal tyrannosauroid, Guanlong wucaii gen. et sp. nov., from the lower Upper Jurassic of the Junggar Basin, northwestern China. G.

The Late Jurassic–Early Cretaceous Rifting
2019During the Late Jurassic and Early Cretaceous, Iberia experienced extensional and transtensional stresses leading to a complex rifting time interval. Africa–America–Europe relative motions determined the definition of the Iberian plate boundaries and the generation of rifted sedimentary basins and sub-basins along its continental margins and in the ...

Indian Ocean sediment distribution since the Late Jurassic
Marine Geology, 1978Cores obtained by deep sea drilling in the Indian Ocean provide a sedimentary record from which are deduced changing patterns of sedimentation through the Late Mesozoic and Cenozoic. Comparisons between: (1) empirical subsidence curves and sediment sequences at individual sites; and (2) paleobathymetric reconstruction maps and past sediment ...

Fusion of caudal vertebrae in Late Jurassic sauropods
Journal of Vertebrate Paleontology, 1991ABSTRACT Fusion of caudal vertebrae in the sauropod dinosaurs Apatosaurus, Diplodocus, and Camarasaurus is explained as the result of ossification of ligaments spanning consecutive centra. The ossification does not involve the intervertebral space or the annulus fibrosus of the disc and therefore represents true bridging.

Late Jurassic Climates, Vegetation, and Dinosaur Distributions
The Journal of Geology, 2004The Jurassic and Cretaceous are considered to have been warmer than today on the basis of various climate data and model studies. Here, we use the available global record of climate-sensitive sediments, plants, and dinosaurs to infer broadscale geographic patterns for the Late Jurassic.

Late Triassic to Late Jurassic petrotectonic history of the Oregon Klamath Mountains
2009ABSTRACT This field guide describes stops in the Oregon Klamath Mountains that visit near-complete ophiolite sections, pre- and post-accretion arc plutons, greenschist- to amphibolite-grade metamorphosed wallrocks, arc volcanic rocks, and interbedded chert, argillite, and olistostromal deposits. Structural features at these stops include

Late Triassic and Early Jurassic palaeogeography of the world
Palaeogeography, Palaeoclimatology, Palaeoecology, 2007Abstract A new version of global and regional palaeogeographic maps is presented for two time intervals. These maps depict the plate tectonic configuration, palaeoenvironment and lithofacies during the Late Triassic (Carnian–Norian) and Early Jurassic (Hettangian–Toarcian) time. The individual maps illustrate the general conditions present during the
