The Geological Orrery is a network of geological records orbitally paced climate designed to address the inherent limitations solutions for planetary orbits beyond 60 million years ago due chaotic nature Solar System motion. We use results from two scientific coring experiments in Early Mesozoic continental strata: Newark Basin Coring Project and Colorado Plateau Project. precisely accurately resolve secular fundamental frequencies precession perihelion inner planets Jupiter Late Triassic...
Significance Geological records of paleoclimate provide the only constraints on Solar System orbital solutions extending beyond ∼50-Ma limit imposed by chaotic diffusion. Examples such are coupled high and low latitude, Triassic–Jurassic (∼198–202 Ma) sedimentary cyclicity in coal-bearing outcrops from ∼60° N-paleolatitude Junggar Basin (Western China), contemporaneous tropical basins. Analysis reveals climate variability dominated obliquity-scale precession-scale tropics. Together, these...

Abundant lake ice-rafted debris in Late Triassic and earliest Jurassic strata of the Junggar Basin northwestern China (paleolatitude ~71°N) indicates that freezing winter temperatures typified forested Arctic, despite a persistence extremely high levels atmospheric P co 2 (partial pressure CO ). Phylogenetic bracket analysis shows non-avian dinosaurs were primitively insulated, enabling them to access rich deciduous evergreen Arctic vegetation, even under conditions. Transient but intense...
Abstract: The Triassic–Jurassic (Tr–J) boundary marks a major extinction event, which (∼200 Ma) resulted in global extinctions of fauna and flora both the marine terrestrial realms. There prevail great challenges determining exact location Tr–J boundary, because endemism taxa scarcity fossils settings leading to difficulties linking sedimentary successions. Investigation based on palynology bivalves has been carried out over 1113 m thick section, is subdivided into 132 beds, along Haojiagou...
Abstract The C retaceous L angshan F ormation, which crops out along the northern portion of hasa block, is composed mainly grey or grey‐black fine‐grained limestones, argillaceous limestones and a few thin‐bedded siltstones silty mudstones. From specimens collected and/or photographed in field, combined with revision taxa previously recorded from four rudist are recognized: (1) A uroradiolites gen. nov.; (2) E oradiolites cf. davidsoni ; (3) M agallanesia rutogensis sp. (4) S ellaea We...
Collective cognition is often mentioned as one of the advantages group living. But which factors actually facilitate smarts? To answer this, we compared how individuals and groups either ants or people tackle an identical ...Biological ensembles use collective intelligence to challenges together, but suboptimal coordination can undermine effectiveness cognition. Testing whether exceeds that individual impractical since ...
The Arabia-Eurasia convergence led to the uplift of Zagros orogenic belt and outward propagation fold-and-thrust system. In this paper we focus on Miocene strata in southwestern Iran study stratigraphic chronology, basin evolution, history Iranian Plateau. Our magnetostratigraphic results enable establishment a time scale ranging from 14 Ma 10 Ma. Petrographic data sandstones indicate remarkable change provenance sediments feldspar sandstone lithic-dominated beginning at 13 U-Pb ages...
Abstract The organic carbon isotope (δ 13 C org ) curve for ~1.7-km-thick mid-Cretaceous strata of the Chaqiela section in Gamba area, southern Tibet is presented this study. C-isotopic chemostratigraphic correlation combined with biostratigraphic constraints show that spans early Aptian through Campanian period, and almost all cycle perturbations Oceanic Anoxic Events during period are well recorded continental margin area southeastern Tethys Ocean. Significantly, two levels methane-derived...
Northeast China's Early Cretaceous Yixian Formation preserves spectacular fossils that have proved extraordinarily important in testing evolutionary hypotheses involving the origin of birds and distribution feathers among nonavian dinosaurs. These occur either flattened with soft tissue preservation (including color) laminated lacustrine strata or as three-dimensional (3D) skeletons "life-like" postures more massive deposits. The relationships these deposits to each other, their absolute...
ABSTRACT A record of the Early Jurassic mass extinction event is reported from eastern Tethyan (Tibetan) locations for first time. In Mount Everest region a thick Lower carbonate formation, here named Yungjia Formation, developed within predominantly clastic Triassic–Jurassic succession. Within formation sharp transition peloidal packstones/grainstones to thin‐bedded, pyritic micrite‐shales interbeds records pulse deepening and development dysoxic bottom waters. Both lithiotid bivalves...
Rudists are a principal biotic component of Cretaceous carbonates in Tibet and the Western Tarim Basin. Barremian to Maastrichtian carbonate units widespread on northern margin Indian Plate Tethyan tectonic slices that were welded onto Eurasia successive stages during Late Paleogene. In far northwestern Tibet, Barremian-Cenomanian endemic rudists cosmopolitan orbitolinid foraminifera occupied isolated platforms eastern Tethys. Rudists, corals, stromatoporoids composed bioherms up 10 m thick...
