Field investigation, Microfacies analysis, and biostratigraphy have been carried out in the central parts of the Ionian Basin (Aetoloakarnania area, Western Greece) in order to decipher the depositional environments that developed during the accumulation of the Upper Cretaceous to Eocene carbonate succession. Three different Standard Microfacies types (SMF) have been observed, corresponding to ...Fossil sites of Late Late Cretaceous period – Nemegtian age (Maastrichtian) or Upper Upper Cretaceous, “Nemegt Formation” (70 million years from now). The richest dinosaur fossil sites are frequently found in areas, such as Bayanshiree, Khongil Tsav, Amtgai, Baishin Tsav, Urulbu khudag, Shar Tsav in the Eastern part of Gobi Desert ...A new enantiornithine bird is described on the basis of a well preserved partial skeleton from the Upper Cretaceous Qiupa Formation of Henan Province (central China). It provides new evidence about the osteology of Late Cretaceous enantiornithines, which are mainly known from isolated bones; in contrast, Early Cretaceous forms are often ...More information: Brian A.

In the Zagros area and the Persian Gulf, Upper Cretaceous carbonate sequences are among the most important hydrocarbon reservoirs. In this study, facies analysis and stratigraphic interpretation of these sequences, Cenomanian-Santonian in age, have been carried out in subsurface sections from various parts of the Zagros area (including the Dezful Embayment and Fars Province) and the Persian ...Upper Cretaceous paleoenvironmental changes and petrophysical responses in lacustrine record (Songliao Basin, NE China) and marine sedimentary deposit (Goban …They are called the Glen Rose Formation and Edwards Group. The rocks east of the Balcones Escarpment are Upper Cretaceous rocks, ranging in age from 70 million to 100 million years. The Upper Cretaceous in the Austin area is composed of the Georgetown, Del Rio, Buda, and Eagle Ford Formations, as well as the younger Austin Chalk and …Lower Campanian (Upper Cretaceous) ammonites from the Merchantville Formation of New Jersey, Maryland, and Delaware W.

Maiasaura (from the Greek μαῖα, meaning "good mother" and σαύρα, the feminine form of saurus, meaning "reptile") is a large herbivorous saurolophine hadrosaurid ("duck-billed") dinosaur genus that lived in the area currently covered by the state of Montana and the province of Alberta, Canada, in the Upper Cretaceous Period (mid to late Campanian), about 76.7 million years ago.May 9, 2022 · Background Dinosaur eggs containing embryos are rare, limiting our understanding of dinosaur development. Recently, a clutch of subspherical dinosaur eggs was discovered while blasting for a construction project in the Upper Cretaceous red beds (Hekou Formation) of the Ganzhou Basin, Jiangxi Province, China. At least two of the eggs contain identifiable hadrosauroid embryos, described here for ... The Chalk Group (often just called the Chalk) is the lithostratigraphic unit (a certain number of rock strata) which contains the Upper Cretaceous limestone succession in southern and eastern England. The same or similar rock sequences occur across the wider northwest European chalk 'province'. It is characterised by thick deposits of chalk, a soft porous white limestone, deposited in a marine ... ….

A recently discovered articulated partial skeleton of Ornithomimus from the Upper Cretaceous Dinosaur Park Formation of Alberta, Canada is remarkable in the extent and quality of preservation of integumentary structures including feathers. It is the first ornithomimid to preserve a tail bearing extensive plumaceous feathers that are slightly more elongate in comparison to those present on the ...Upper Cretaceous rocks form a virtually continuous blanket over the Gulf of Mexico basin. Overall, the inner edge of the northern outcrop parallels the deeply buried Paleozoic Ouachita orogenic belt. Conspicuous projecting features, such as the Rio Grande and Mississippi embayments, are situated on pronounced salients of the older Ouachita ...

To date, the most complete and largely articulated specimen is the holotype of Sachicasaurus vitae Páramo-Fonseca et al., (2018) from the upper Barremian (Lower Cretaceous) of Colombia. It is 990 cm long measured from the tip of the snout to the posterior end of the last preserved caudal vertebra (Páramo-Fonseca et al., 2018).The provenance of the Upper Cretaceous Nubia sandstones from four vertical sections along Qena-Safaga and Qena-Quseir roads in central Eastern Desert of Egypt was investigated based on their modal composition and geochemical data.

It includes a well-preserved skull, dorsal, sacral, caudal ...The Yezo Group, and other Upper Cretaceous units in Japan, have yielded various marine vertebrates from all stages, although fragmentary remains dominate the fossil record (e.g, Obata et al., 1972; Sato et al., 2012). Further careful search for pliosaurid remains in these strata are necessary to verify whether the demise of the pliosaurids also ... craigslist charlotte missedbutane autozone A similar reduction trend can also be traced among the fossil pollen organs. Modern type pollen organs occur in the Upper Cretaceous (Maastrichtian or Campanian) of Canada (Serbet, 1996, Rothwell and Holt, 1997; Crane, pers. comm.), while Ginkgo liaoningensis (Liu et al., 2006) of the Lower Cretaceous bears more than two pollen sacs.The provenance of the Upper Cretaceous Nubia sandstones from four vertical sections along Qena-Safaga and Qena-Quseir roads in central Eastern Desert of Egypt was investigated based on their modal composition and geochemical data.

Two new leptoceratopsids are described from the Campanian and Santonian of Alberta. The Campanian taxon has a unique dentary tooth shape not shared by other leptoceratopsids. The Santonian taxon represents the oldest known leptoceratopsid (∼83 Ma). The Santonian taxon represents the smallest adult-sized ceratopsian from North America.Goannas evolved in the northern hemisphere in the Upper Cretaceous Period about 90 million years ago.
