Specimens referable to the two recognized morphospecies of Triceratops, T. horridus and T. prorsus, are stratigraphically separated within the HCF with the T. prorsus ...The 1983 North American Stratigraphic Code adopted the formal terms lithodeme, which is comparable to a formation; a suite, which is analogous to a group, and a supersuite, similar to a supergroup. A lithodeme is the fundamental unit and should possess distinctive and consistent lithological features, comprising a single rock type or a mixture ...Nine fossiliferous intervals were recognized by El-Asa'ad (1983b) within the Aruma Formation and these ranged from Coniacian to late Maastrichtian. The main difference between this and the stratigraphic scheme of Powers et al. (1966) and Powers (1968) was the assignment by El-Asa'ad of the lower part of the Khanasir Limestone Member to the Coniacian, based on ammonites in this unit being ...Learn more.

The Smackover Formation has been a prolific source of petroleum.The Upper Indus Basin, in Pakistan's western Salt Range, is home to the Zaluch Gorge. The sedimentary rocks found in this Gorge, belonging to the Chhidru Formation, were studied in terms of sedimentology and stratigraphy, and provide new insights into the basin paleogeographic evolution from the Precambrian to the Jurassic period. Facies analysis in the Chhidru Formation deposits allowed the ...stratigraphic reports is to place the geologic-map explanation and the stratigraphic chart alongside the geology section of the text. As the geology section is read, it can easily be compared with the other two parts. An assessment may be made at that time con- cerning stratigraphic changes and conformance with the code.Sep 18, 2023 · Search the Australian Stratigraphic Units Database Stratigraphic Units Search.

Between 1.4 billion and 990 mya, volcanic activity, crustal rifting and filling of basins (formed by rifting) took place. Between 990 and 880 mya, a mountain range formed in eastern Ohio. Between 880 and 544 mya, these mountains were eroded, reducing the landscape to a gently rolling surface.The Upper Maastrichtian fluvial Hell Creek Formation of the Fort Peck Lake area, Montana (and regional equivalents) is notable for its vertebrate fossils and for the K-Pg mass extinction at or near its upper contact.
