	Callovian - LoveToKnow 1911
		CALLOVIAN (from Callovium, the Latinized form of Kellaways, a village not far from Chippenham in Wiltshire),,in geology, the name introduced by d'Orbigny for the strata which constitute the base of the Oxfordian or lowermost stage of the Middle Oolites.
		Rocks of Callovian age (according to the continental classification) are widely spread in Europe, which, with the exception of numerous insular masses, was covered by the Callovian Sea.
		Clays and shales with ferruginous oolites represent the Callovian of Germany; while in Russia the deposits of this age are mainly argillaceous.

		At this meeting there was disagreement as to whether the Callovian Stage should be included in the Middle or Upper Jurassic, but a small majority favoured the latter and that recommendation will be put forward at the next meeting of the international committee.
		It is hoped to communicate all the Committee's revised recommendations to Nature in the near future.

		The Sauropterygia were marine predators of the Mesozoic, which includes the Triassic near shore Nothosauria and Pachypleurosauria, and the post-Triassic, fully marine, Plesiosauria; the Plesiosauria comprises the short-necked pliosaurs and the longer-necked plesiosaurs.
		Five genera of Callovian pliosaurs are currently recognised, but this work concentrates on the three short-snouted genera; Liopleurodon (of BBC "Walking with Dinosaurs" fame) Simolestes, and the newest genus Pachycostasaurus.
		Following clarification of short-snouted Callovian pliosaur cranial taxonomy, never before attempted reconstructions are presented, and the skull, mandible and teeth are fully described.

		The Callovian and Oxfordian strata of the Russian Platform are characterised by abundant and diverse dinoflagellate cysts.
		In the early and mid Callovian, the diversity is relatively low.
		However, from the late Callovian to the mid Oxfordian, dinoflagellate cyst diversity increased markedly and the stratigraphic ranges of key taxa are virtually identical throughout western and eastern Europe.

	Faunal Invasions As a Source of Morphological Constraints and Innovations? The Diversification of the Early ...
		We observe a progressive and sustained increase until the Ishmae zone (#06; mid-Bathonian) which can be attributed to (1) the progressive recovery of thick forms (trend of the minimum values on PC 1) and (2) the individualization of microconchs inducing a major increase in morphospace occupation.
		A new morphospace structure is obtained either by destruction of the initial arrangement (e.g., extinction of some peak), or by modification of the initial arrangement by acquisition of a new peak and its superimposition on the former one (e.g., origination of a new peak).
		At the very onset of the early Callovian, expansion of the geographic area by ingression into new provinces entailed a reorganization of the morphospace with the origination of a new peak in association with the two existing ones.

	A SHALLOW-WATER MICROSOLENID COMMUNITY FROM THE JURASSIC (CALLOVIAN) OF SOUTHERN ISRAEL
		Platy microsolenid corals have been used as paleoenvironmental indicators of deep water for at least three decades because of structural similarities between them and the extant coral Leptoseris fragilis, which is found only in deep water (90-130 meters) in the Gulf of Aqaba near Eilat, Israel.
		These openings were present in the microsolenids as shown by a particular skeletal modification essential to them, but there can be no evidence of bioluminous cell clusters in these fossils.
		A newly discovered microsolenid community from the Matmor Formation (Callovian, Middle Jurassic) of Hamakhtesh Hagadol in the Negev Desert of southern Israel is not consistent with the current paleoenvironmental model derived from L.

		Excellently preserved ostracods from large blocks of the late Callovian (Quenstedtoceras lamberti Zone) fl clays occurring within glacial drift near Łuków, eastern Poland, are described.
		The ostracods are of late Callovian age as indicated by the presence of Nophrecythere triebeli, Progonocythere callovica and advanced evolutionary forms of Nophrecythere intermedia and Terquemula lutzei.
		The most probable source of the Łuków clay blocks seems to be from the bed of the Baltic Sea north of Gdańsk.

		By the end of the early Callovian, the carbonate production on platform located in the mid-latitudes (above 25° lat, W-Europe and E-Africa) was completely shutdown, and transferred to the equatorial area (e.g.
		The model is forced with geological evidences of the timing of the evolution of carbonate production in the mid and low latitudes.
		We found that, when carbonate production is progressively reduced in the mid-latitudes, and finally transiently shut down everywhere, global climate gets transiently cooler by more than 5°C, coevally with an atmospheric CO drop by 600 ppmv (from 900 ppmv in the early Callovian, down to 300 ppmv at the Callovian-Oxfordian boundary).

		On maps showing the solid geology of England, Middle Jurassic rocks crop out in an almost continuous strip from the Dorset coast to the North Yorkshire coast.

		Extensional tectonics in the Central Graben were initiated during the Middle Callovian, with the deposition of continental sediments.
		The first pulse ranged from the Callovian to the Early Oxfordian, the second pulse was initiated in the latest Late Kimmeridgian and lasted for most of the Early Volgian, and the third and final pulse occurred within the Ryazanian in the Early Cretaceous.
		The boundary between Middle-Upper Callovian mudstones in the upper part of the underlying Fossilbjerget Formation and the Upper Callovian Athene Member sandstones formed at the turn-around point between sea-level rise and fall.

	Tectonics of the Australian northwest shelf
		For example, in the Dampier sub-basin, the Callovian extension was accommodated along the Madeleine Trend and the Lewis Trough and the Lambert Shelf represented the collapsed hangingwall block, whereas in the central Barrow sub-basin, the extension was accommodated along the Flinders Fault System with the Peedamullah Shelf being the footwall block.
		The fault reactivation associated with the Tithonian extensional event increases to the south and is responsible for the formation of the Jurabi Horst.
		During the first three phases of extension along the northwest Australian margin, the "present-day" Jurabi Horst was a structural low (i.e., Permian, late Triassic, and Callovian) and during the fourth phase of extension (Tithonian) was uplifted and became a structural high covered by thick Jurassic syn-rift deposits.
