Dredge samples of Upper Jurassic-lowest Cretaceous limestones were recovered from western Galicia margin. Limestones include benthic and/or planktonic assemblages, which were deposited in environments ranging from inner to outer shelf or upper slope.

Belemnites (Order Belemnitida), a very successful group of Mesozoic coleoid cephalopods, dominated the world's oceans throughout the Jurassic and Cretaceous. According to the current view, the phylogenetically earliest belemnites are known from the lowermost Jurassic (Hettangian, 201-199 Ma) of northern Europe. They are of low diversity and have small sized rostra without clear grooves. Their d...

SYNOPSIS Suuwassea emilieae is a recently described dinosaur taxon discovered in the Upper JurassicMorrisonFormationof thewesternUnitedStatesand theonlynon-diplodocidflagellicaudatan (Dinosauria: Sauropoda) known fromNorth America. It retains sauropod symplesiomorphies that are unexpected in a Late Jurassic taxon and thus sheds light on the evolutionary origins of the Flagellicaudata. Despite b...

Dinosaur skeletal remains are almost unknown from northern South America. One of the few exceptions comes from a small outcrop in the northernmost extension of the Andes, along the western border of Venezuela, where strata of the La Quinta Formation have yielded the ornithischian Laquintasaura venezuelae and other dinosaur remains. Here, we report isolated bones (ischium and tibia) of a small n...

INTRODUCTION The normal flora can be divided into two groups Resident flora and Transient. Some organisms are almost always present in a normal oral cavity and constitute constant/normal microbial flora. It is further divided into two types: indigenous & supplemental. Comprise of those species that are almost always present in high numbers (> 1%) in a particular site, such as the supra gingival...

The southern and tropical southeastern regions of the Yunnan Province in southwestern China have similar monsoonal climates and lowland tropical rain forest vegetations. The floras of both regions are dominated by tropical floristic elements (78.3% in southern Yunnan and 68.83% in southeastern Yunnan), and both belong to the Indo-Malaysian flora at the northern margin of tropical Asia. However,...

the present article is a review of a palaeobiogeographic analysis of jurassic ostracods from east africa, india and madagascar and includes also some general remarks on palaeobiogeography, biodiversity and ostracod ecology.the palaeobiogeographic study shows the high significance of this microfossil group for the reconstruction of palaeogeographic processes, particularly plate tectonic developm...

BACKGROUND To evaluate associations between alterations in vaginal flora and clinical symptoms in low-risk pregnant women. METHODS Vaginal specimens from 245 pregnant women were analyzed by microscopy for vaginal flora. Signs and symptoms of vaginal infection were determined by patient interviews and gynecologic examinations. RESULTS Abnormal vaginal flora was identified in 45.7% of the sub...

Plant fossil-bearing mudstones of Jurassic age are present in a small faulted basin within the Precambrian basement rocks at Tabbowa village, in the North Western province of Sri Lanka. The present study was conducted in the Tabbowa sedimentary beds and reports discovery of two new plant species that could probably be affiliated to Otozamites of Bennettitales group that prevailed in the Jurassi...

Morphological responses of nonmammalian herbivores to external ecological drivers have not been quantified over extended timescales. Herbivorous nonavian dinosaurs are an ideal group to test for such responses, because they dominated terrestrial ecosystems for more than 155 Myr and included the largest herbivores that ever existed. The radiation of dinosaurs was punctuated by several ecological...
