An unusual titanosaur axis from the Upper Cretaceous of Brazil and its significance for sauropod anatomy and systematics

The Anatomical Record, EarlyView.
Abstract The Upper Cretaceous São José do Rio Preto Formation (Bauru Group, southeastern Brazil) has yielded a fragmentary but taxonomically diverse record of titanosaur sauropods, although elements from cervical series remain scarce. Here, we describe a nearly complete sauropod axis from the Vila Ventura Paleontological Area, representing an uncommon ...

Facies variability of pennsylvanian oil-saturated carbonate rocks (constraints from Bashkirian reservoirs of the south-east Tatarstan)

Georesursy, 2020
One of the strategic ways of the old oil-producing regions is to further prospecting for potentially promising areas for hydrocarbon. One of these exploration areas is the Volga-Ural region.

Microfacies, depositional environment, sequence stratigraphy and diagenetic process affected the Doroud Formation in the Eram Section (south Neka), north flank of central Alborz [PDF]

Journal of Stratigraphy and Sedimentology Researches, 2020
The Permian deposits (Doroud Formation) are exposed in a wide area of central Alborz. A stratigraphic section of Permian deposits in the Eram section (South Neka) has been selected for the study of facies, depositional environments, sequence stratigraphy,

On the peritidal cycles and their diagenetic evolution in the Lower Jurassic carbonates of the Calcare Massiccio Formation (Central Apennines) [PDF]

, 2015
This paper shows the environmental changes and high-frequency cyclicity recorded by Lower Jurassic shallow- water carbonates known as the Calcare Massiccio Formation which crop out in the central Apennines of Italy.

Osteohistology of two phorusrhacids reveals uninterrupted growth strategy

The Anatomical Record, EarlyView.
Abstract Phorusrhacidae were apex predators that primarily dominated South America ecosystems for at least 40 million years with their imposing size and predatory lifestyle—yet some aspects of their biology remain poorly understood. Osteohistology is a tool for understanding growth dynamics and biomechanical adaptations.

Geochemical characterization of the hydrous pyrolysis products from a recent cyanobacteria-dominated microbial mat

Geologica Acta, 2016
Hydrous pyrolysis experiments were performed on a recent microbial mat sample from Lagoa Vermelha, Brazil, to determine whether crude oil can be generated and expelled during artificial maturation of the Organic Matter (OM).

New data on depositional environment of Jurua Formation terminal sediments, Solimoes Basin, Brazil

Georesursy, 2019
It has been for the first time established on the core taken from two wells that JR10 reservoir sediments (Upper Jurua, Formation Carboniferous) were deposited in the conditions of deltaic and alluvial coast with semiarid climate and in marine ...

Widespread distribution of large silesaurids evidenced by a new record from the Middle Triassic of southwest Gondwana

The Anatomical Record, EarlyView.
The largest silesaurid known from South America is described here, demonstrating that silesaurids reached large body sizes in southwestern Gondwana. This discovery further underscores the widespread geographic distribution and temporal persistence of large silesaurids across Pangea, despite faunal turnovers and environmental events such as the Carnian ...
