Diversity and biogeography patterns of Late Jurassic neoselachians (Chondrichthyes: Elasmobranchii)
Geological Society, London, Special Publications, 2008Abstract The regional diversity and biogeographic patterns of Late Jurassic neoselachians at genus level in Europe were analysed based on samples and an extensive literature survey of about 40 localities ranging from the Oxfordian to Tithonian.

EXCEPTIONALLY PRESERVED LATE JURASSIC GASTROPOD EGG CAPSULES
PALAIOS, 2015Exceptionally preserved, phosphatized gastropod egg capsules from the uppermost Jurassic (upper Volgian) in Central Russia are reported. The egg capsules were attached to the inner side of the shell wall of empty body chambers of two ammonites. Due to phosphatization, the egg capsules retained their original morphology preserving both the lower ...

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 ...

A Late Jurassic Mafic Pluton in Newfoundland
Canadian Journal of Earth Sciences, 1974A small alkaline ultramafic intrusion in central Newfoundland is dated as 135 ± 8 m.y. old and 139 ± 9 m.y. old by the K–Ar method on biotite. This is the first known Mesozoic pluton (aside from dikes) in Newfoundland. The occurrence, composition and age of the pluton and associated igneous rocks is similiar to, and perhaps related in origin to ...

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.

Giant late Jurassic sabkhas of Arabian Tethys
Nature, 1977THE discovery that anhydrite–gypsusm evaporites with characteristic textures are forming today in the shallow subsurface of supratidal coastal sabkhas and in continental sabkhas from Arabia1,2 has revolutionised the interpretation of ancient evaporite sucessions.

Tooth Replacement in Late Jurassic Dryolestidae (Eupantotheria, Mammalia)
Journal of Mammalian Evolution, 1997The discovery of juvenile dentitions of late Jurassic (Kimmeridgian) Dryolestidae (Eupantotheria, Mammalia) from Guimarota, Portugal, yields for the first time information on the mode of tooth replacement in therian mammals prior to the dichotomy of placentals and marsupials. As in extant placentals, tooth replacement occurs at all antemolar positions [

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.
