Late Jurassic Climates, Vegetation, and Dinosaur Distributions

The Journal of Geology, 2004
The 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, 1977
THE 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.

A Late Jurassic Digging Mammal and Early Mammalian Diversification

Science, 2005
A fossil mammal from the Late Jurassic Morrison Formation, Colorado, has highly specialized teeth similar to those of xenarthran and tubulidentate placental mammals and different from the generalized insectivorous or omnivorous dentitions of other Jurassic mammals.

Earliest Cretaceous-Late Jurassic of southern Rovuma Basin

Proceedings, 2017
Summary Statoil together with partners drilled Cachalote 1/1A in 2013. The results of the Late Jurassic and earliest Cretaceous in these boreholes are compared to outcrops in Nacala and published stratigraphy and sedimentary environment of the area.

Tooth Replacement in Late Jurassic Dryolestidae (Eupantotheria, Mammalia)

Journal of Mammalian Evolution, 1997
The 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, 1991
ABSTRACT 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.

Middle and Late Jurassic terebratulides from New Zealand

Palaeoworld, 2016
Abstract Terebratulide brachiopods are found throughout the New Zealand Mesozoic, and by the Jurassic are second only to rhynchonellides in abundance and diversity. Only two species have been described from the Late Jurassic, Kutchithyris hendersoni Marwick, 1953 and Holcothyris (?) kaiwaraensis Campbell, 1965 . In this study, one new genus and 14

Late Jurassic Mammals from Tendaguru, Tanzania, East Africa

Journal of Mammalian Evolution, 1998
Records of Mesozoic mammals are extremely rare in Africa. The only previous record from the Upper Jurassic of Africa is a fragmentary mandible without teeth of Brancatherulum tendagurense. Here I report the discovery of two new mammals from the Upper Jurassic of Tendaguru, Tanzania.

Characteristics of Yichun Late Triassic - Early Jurassic Monzogranite

Applied Mechanics and Materials, 2011
As building material, Granite has been extensively used. It is important to clear the geochemical characteristics of granites. The paper introduce the Late Triassic-Early Jurassic monzogranite, it mainly located in the south of Yichun area, which were intruded by medium grain monzogranite and syenogranite in Late Triassic-Early Jurassic.
