Mosasaurids (Mosasauridae) were specialized marine lizards that evolved and radiated in the Late Cretaceous. Their diversity peaked Maastrichtian, with most diverse faunas known from Morocco. Here we describe a new species of mosasaurid this fauna. Pluridens serpentis sp. nov. is described based on two complete skulls referred jaws. It to elongate robust jaws, small teeth, tooth implantation. H...

The deposits corresponding to the Upper Cretaceous Neuquén and San Jorge Gulf basins from northern central Patagonia have provided two of most complete sequences terrestrial vertebrate faunas all Gondwanan landmasses. Among carnivorous components, carcharodontosaurid theropods appeared as common elements during Early earliest Late in Patagonia. Although recorded mostly lower Turonian, isolated ...

The non-marine trigonioidid bivalves show five phases of radiation in the Cretaceous of Pal-Asia: pre-Aptian (?Valanginian/Hauterivian-Barremian), Aptian, Albian, Cenomanian and Turonian-Maastrichtian. Their distribution patterns show two distinct palaeo-river systems feeding trigonioidids. Before the Cenomanian, the river system occupied the southwestern-southern-southeastern Pal-Asian contine...

Five subsurface sections and a large number of thin the Hartha Formation (age Late Campanian – Early Maastrichtian) were studied to unravel depositional facies environments. The is important as an oil reservoir in Iraq. Petrographic microfacies analysis selected wells from Balad East Baghdad fields Central Iraq, enable recognition three main Sedimentary paleoenvironments. These are restricted m...

Abstract The extinction of non‐avian dinosaurs and its cause(s) have been a matter debate for several decades. Here we measured Hg isotopic composition, heavy metals, magnetic parameter in terrestrial basin southeastern China. exhibited anomalies from 66.4 to 65.6 Ma, with near‐zero positive Δ 199 values, which reflected the eruption Deccan Traps (DT) magma. In addition, coincided gradual dinos...

Speed estimations from trackways of Titanopodus mendozensis González Riga and Calvo provide information about the locomotion of titanosaurian sauropods that lived in South America during the Late Cretaceous. Titanopodus ichnites were found at Agua del Choique, a newly discovered track site in the Loncoche Formation, Late Campanian-Early Maastrichtian of Mendoza, Argentina. This speed study foll...
