Exempel på hur man kan använda HETTANGIAN i en mening

• Its age corresponds to the Rhaetian to lower Sinemurian stages of the geologic timescale, thus fully including the Hettangian stage.
• It was preceded by the Norian and succeeded by the Hettangian (the lowermost stage or earliest age of the Jurassic).
• The Hettangian follows the Rhaetian (part of the Triassic Period) and is followed by the Sinemurian.
• In Europe the Sinemurian age, together with the Hettangian age, saw the deposition of the lower Lias, in Great Britain known as the Blue Lias.
• Its remains include an ilium, maxilla, astragalus and humerus, which date variously from the Norian and Rhaetian stages of the Late Triassic, or possibly as late as the Hettangian stage of the Early Jurassic.
• Lycorhinus is a genus of heterodontosaurid ornithischian dinosaur from the Early Jurassic (Hettangian to Sinemurian ages) strata of the Elliot Formation located in the Cape Province, South Africa.
• Fissures, created by the uplift, folding and faulting of the Carboniferous Limestone, periodically opened and closed which were filled with deposits of Rhaetic, Hettangian, Sinemurian, Pliensbachian, Toarcian and Bathonian ages.
• It was collected by James Kitching and Regent "Lucas" Huma in sandstone that was deposited during the Hettangian stage of the Jurassic period, approximately 201 to 199 million years ago.
• From the Hettangian to Pliensbachian stages (201 to 183 Ma), the area reacquired a deeper basinal environment.
• Thecodontosauridae is a family of basal sauropodomorph dinosaurs that are part of the Bagualosauria, known from fossil remains found exclusively in the Magnesian Conglomerate of Bristol, England, which dates back to the Rhaetian stage of the Late Triassic (although it could be as old as the Norian stage of the Late Triassic and as young as the Hettangian stage of the Early Jurassic).
• The Lias is composed of Hettangian (sandstones, coarse sandstones and conglomerates), Sinemurian (oolithic limestones, sometimes dolomitic) and Toarcian (claystones and grey marls).
• Pentacrinites is an extinct genus of crinoids that lived from the Hettangian to the Bathonian of Asia, Europe, North America, and New Zealand.
• The fossils of this genus are common on the eastern North American Margin, being a key taxon of the Newark Supergroup, and recovered from units such as the Bull Run Formation (Norian, Virginia), Lockatong Formation (Norian, Pennsylvania), Stockton Formation (Norian, New Jersey), Solite Quarry (Norian, North Carolina-Virginia), Midland Formation (Hettangian, Virginia), East Berlin Formation (Hettangian, Connecticut), Boonton Formation (Sinemurian, New Jersey) and the Portland Formation (Hettangian-Pliensbachian, Connecticut).
• Since the beginning of the jurassic, from Hettangian to earliest Sinemurian on the western Lombardy Basin there was a notorious continental area that was found to be wider than previously thought, where a warm humid paleoclimate developed.
• The Boonton Formation rests conformably above the Hook Mountain Basalt, placing its deposition sometime between approximately 197 and 190 million years ago during the late Hettangian stage and Sinemurian stage of the Jurassic.
• The Precipice Sandstone an Early Jurassic (Sinemurian to early Pliensbachian, with possible Hettangian levels) geologic formation of the Surat Basin in New South Wales and Queensland, eastern Australia, know due to the presence of abundant vertebrate remains & tracks.
• Qomoqomosauropus is an ichnogenus of an unknown reptile footprint that lived from the Hettangian to Pliensbachian periods of the Early Jurassic.
• The various fossils attributed to this species have been dated over a relatively large time span – the Hettangian, Sinemurian, and Pliensbachian stages of the Early Jurassic – meaning the fossils represent either a highly successful genus or a few closely related animals all currently assigned to Coelophysis.
• Atychodracon is an extinct genus of rhomaleosaurid plesiosaurian known from the Late Triassic - Early Jurassic boundary (probably early Hettangian stage) of England.
• Lockley and Christian Andreas Meyer published more research on the possible Hettangian stegosaur footprints from France.
