		During the Artinskian (Figure 2), Pangea moved off the southern pole and glaciers disappeared altogether.
		The end for Permian (Figure 6) conodont lineages is marked by the Late Griesbachian conodont crisis (Mei et al., 1999a), which is represented by the extinction of Hindeodus and Isarcicella, and an afterward flooding survival fauna exclusively dominated by Clarkina carinata (Clark, 1959).
		Like the Early Permian crisis caused by the Artinskian global warming, the Late Griesbachian conodont crisis is a response to early Triassic global warming (Erwin et al., 1999).

	Journal of Paleontology: Artinskian conodonts from the Dingjiazhai formation of the Baoshan block, west Yunnan, ...
		The Dingjiazhai Formation is overlain paraconformably by the Woniusi Formation, which is represented mostly by basalts and basaltic volcaniclastics related to rifting volcanism during the separation of the Baoshan Block from Gondwanaland.
		The present discovery of conodonts from the upper part of the Dingjiazhai Formation reveals that the glaciogene diamictites in the Dingjiazhai Formation are older than middle Artinskian, and the inception of rifting volcanism of the Baoshan Block is later than middle Artinskian.
		This Artinskian fauna provides strong chronologic constraints on the timing of the deposition of glaciogene diamictites in the Dingjiazhai Formation and the eruption of rifting-related basalts found in the overlying Woniusi Formation.

		The Artinskian through Lopingian zones of the peri-Gondwana Cool Water Province are based on material from Australia (Nicoll and Metcalfe, 1998) for Cisuralian, the Salt Range for Guadalupian and Lopingian (Wardlaw, 1995; Wardlaw and Mei, 1999), and Selong for the latest Lopingian.
		Wardlaw (personal communication, 1999) has suggested that the same zonation of Asselian through Artinskian can be found in the Phosphoria Basin, Texas and the Urals.
		Artinskian and Kungurian conodont taxonomy and zonation are the weakest parts in the study of Permian conodonts and subject to further modification.

		For this reason there is a general consensus on the global stratigraphic positions of the stage boundaries for the three oldest stages in the Permian: Asselian, Sakmarian and Artinskian.
		The age determination for their time scale is based on the distribution of "tie points"- rock samples with a combination of isotopic ages and fossils that can be used to correlate the stratigraphy.
		All of their ages within the Permian are interpolated from one weak tie point at the Permian/Triassic boundary, and two "pseudo tie points" in the mid Artinskian and at the Permo-Carboniferous boundary.

	Babel \| Beetles of the Permian Period
		But neither the drawings nor descriptions of those have been made yet, so that their true nature remains unknown.
		The most ancient described beetles come from deposits of the next Sakmarian layer (sometime an even younger Artinian (Artinskian) layer is indicated) of Boskovice graben in eastern Czechia.
		Ponomarenko points out that the venation (arrangement of veins) pattern of their cellular elytra (wing structure) resembles that of forewings of ancient insects called megalopterans.

		Comments: Very similar to, perhaps a descendent of, the Artinskian Casea halselli, but rather larger in size.
		Comments: Probably a descendent of the latest Artinskian age Cotylorhynchus romeri, this is likewise a very large, heavily built animal.
		In fact this huge but gentle herbivore is the largest known caseid, the largest known pelycosaur, and for its time the largest tetrapod ever.

		Medlicottia orbignyana (Verneuil, 1845) occurs mainly in the Artinskian of the Urals and was also reported from the Bitauni Bed of Timor; here, it may represent an extension into the Kungurian.
		Therefore, the ammonoid complex from Qiemo is basically of Kungurian age and rather closely resembles those from the Kochusu and Shindy Formations (Buz.-Tere ammonoid complex) plus the bed of MLiellina daudiae (Deprat, 1912) of the Pamir.

		Heterogeneous reef and platform carbonate reservoirs range in age from Late Devonian (Famennian) to Early Permian (Artinskian).
		From Late Devonian to Early Carboniferous, a peritidal ramp evolved into an isolated platform along the northern margin of the Precaspian basin.

		These three sequences were interrupted by two major regressive events: first, the Namurian Uplift ranging in age from Serpukhovian to Gzhelian, and second, the Post-Sakmarian Regression occurring probably at Artinskian time in the Baoshan block, although the precise time interval of the latter event is still unclear.
		The Baoshan block is characterized by warm-water, highly diverse and abundant faunas during the Early Carboniferous, by cold-water and low diversity faunas during the Early Permian, and by possibly warm-water but low diversity faunas during the Middle Permian.
		The Sweetognathus bucaramangus conodont fauna constrains the upper boundary of the diamictite-bearing siliciclastic deposits (Dingjiazhai Formation) to the Sakmarian to early Artinskian, as well as the eruption of the rifting basalts (Woniusi Formation) to, at least, the post-early Artinskian.

	THE "HERCYNIAN EVENT" IN ARABIA AND NORTH AFRICA - TIMING, DISTRIBUTION AND POSSIBLE CONTROLS (Site not responding. Last check: 2007-10-14)
		In eastern Libya and Egypt, two discrete unconformities exist of early Permian and late Carboniferous age.
		In Arabia, Westphalian to Artinskian clastic sediments of the Haushi and Unayzah Formations unconformably overlie Carboniferous and older strata.
		This general younging of uplift and erosion to the east is inconsistent with the well-constrained timing of Hercynian compressional deformation in Europe and northwestern Africa.

		Application of graphic correlation to compare Lower Permian sections of the Glass Mountains, West Texas and the Western Slope of the Ural Mountains, Russia
		An Artinskian-Kungirian Global Boundary Stratotype Section and Point (GSSP) has been proposed for two stratigraphic intervals: the Artinskian through Kungurian stages of the western slope of the Ural Mountains, Russia, and the Leonardian Series of the Glass Mountains, West Texas.
		Graphic correlation applied separately to each of these intervals produced a viable composite section for the Glass Mountains Leonardian succession, whereas a composite section for the Artinskian-Kungurian succession could not be constructed within an acceptable level of confidence.

		During the Moscovian to Asselian, highly diversified associations typified by various calcareous green algae, Palaeoaplysina, Tubiphytes, fusulinids, smaller and encrusting foraminifers (Chloroforam Association) prevailed in carbonate sediments from supratidal to shallow subtidal environments.
		During the Sakmarian and Early Artinskian, oolitic carbonate sands (Chloroforam Association) typified intertidal flats, whereas shallow subtidal environments were occupied by moderately diversified associations with fusulinids, smaller foraminifers, echinoderms and bryozoans (Bryonoderm-extended Association) and poorly diversified associations with echinoderms, brachiopods and bryozoans (Bryonoderm Association).
		During the Late Artinskian to Kazanian, poorly diversified associations characterised by brachiopods, echinoderms and bryozoans (Bryonoderm Association), and sponge-dominated associations (Hyalosponge Association) reigned within siliceous carbonates of intertidal and shallow subtidal environments.

		The Permian Ishbel Group, in the Telford thrust plate near Fernie, southeastern British Columbia, includes in ascending order, the Johnston Canyon (phosphatic shale and siltstone), Telford (sandy carbonates), Ross Creek (phosphatic siltstones and carbonates), and Ranger Canyon (diagenetic chert complex) formations.
		The sequence can be subdivided into five conodont zones including: (1) Idiognathodus ellisoni (Asselian to early Sakmarian); (2) Streptognathodus elongatus (late Sakmarian); (3) Neogondolella bisselli-Sweetognathus whitei (early Artinskian); (4) Neostreptognathodus pequopensis-N. exsculptus (early Artinskian); and (5) Neostreptognathodus ruzhencevi-N. pnevi (early Artinskian).
		To date, conodonts have not been recovered from the Ranger Canyon Formation, which has been dated as late Artinskian to Wordian on the basis of other faunas.
