Exempel på hur man kan använda AALENIAN i en mening

• The geology of Bridport comprises rocks formed in the Pliensbachian, Toarcian, Aalenian, Bajocian, Bathonian and Callovian ages of the Jurassic Period, overlain by superficial Quaternary deposits of alluvium alongside the rivers.
• They first appeared in the fossil record in the Early Jurassic; the oldest known orectolobiform genera are Folipistrix (known from Toarcian to Aalenian of Belgium and Germany), Palaeobrachaelurus (Aalenian to Barremian) and Annea (Toarcian to Bajocian of Europe).
• The top of the Aalenian (the base of the Bajocian) is at the first appearance of ammonite genus Hyperlioceras.
• The oil in the Mittelplate field is trapped in Dogger (Middle Jurassic) sandstones of uppermost Aalenian to lowermost Callovian in age.
• In 2006, Bandyopadhyay and Sengupta argued that the fish fauna suggested a Toarcian age for the Upper Kota Formation, possibly extending into the Aalenian, and in turn estimated the Lower Kota to be Sinemurian to Pliensbachian in age.
• Recent work has suggested that the base of the formation was formed around 171 Ma, during the upper Aalenian, with the main age for the Lower Las Chacritas Member being around 168 Ma, during the Bajocian, Bathonian and Callovian, while the overlying Puesto Almada Member seems to be around 158 Ma, or Oxfordian in age.
• Glaphyrorhynchus is an extinct genus of teleosaurid thalattosuchian from the Middle Jurassic (Aalenian) of southern Germany.
• Traditionally it has been considered to be a unit whose age has been calculated in between the Pliensbachian and Toarcian stages of the Early Jurassic, with some layers suggested to reach the Aalenian stage of the Middle Jurassic, yet modern data has found that an Early Pliensbachian to Latest Toarcian age is more possible.
• ! Substages of the Aalenian to Bathonian Ages !! Geological formations within the Great Oolite Group!! Rock units found at Finedon Gullet.
• sarstedtensis, originally classified as a species of Heterodontus, from the Toarcian and Aalenian of Germany, with a sixth indeterminate species known from the Toarcian-aged Variabilis layer of the La Couche à Crassum (part of the larger Posidonia Shale) of Luxembourg.
• Teleosaurid and metriorhynchid teeth are described from, respectively, the Middle Jurassic (Aalenian) and Upper Jurassic (Tithonian) of Slovakia by Čerňanský et al.
• With both, the palynological and sedimentological study of all available exposures and cores from the Lower–Middle Jurassic shows that the Hasle Formation (Lower–Middle Pliensbachian) is covered by a succession referable to both the Levka and Sorthat beds, which are composed mostly by bioturbated sands, heteroliths and clays along with abundant coal veins, and contain relatively diverse brackish to marine dinoflagellate assemblages that are indicative of upper Pliensbachian, Toarcian and possibly lower Aalenian strata.
