	Ypresian Stage, Paleogene Period in Hampshire - Hampshire Museums Service
		In Hampshire and the Isle of Wight the Ypresian stage (formerly known as the early or Lower Eocene) is represented by approximately 100 metres of sands and clays, collectively known as the Thames Group.
		The Ypresian stage is present in the sea cliff at Whitecliff and Alum Bays and underlies the northern part of the Isle of Wight.
		The fossil fauna of the Ypresian stage is dominated by invertebrates, particularly molluscs.

		A late early Eocene (Ypresian) to early middle Eocene (Lutetian) age range for the Fossil Butte palynoflora is suggested by the co-occurrence of Bombacacidites, Eucommia, Pistillipollenites mcgregorii, Platycarya platycaryoides, and Momipites triradiatus.
		The results of this comparison confirm that most of the Fossil Butte palynoflora is late early Eocene (late Ypresian or Lostcabinian) in age as suggested by the occurrence of Lambdotherium in the middle unit (Froehlich and Breithaupt, 1997).
		Further taxonomic and stratigraphic resolution of the Fossil Butte palynoflora, new tuff samples for age dating utilizing new analytical techniques, and additional study of the mammal fossils in Fossil Basin is needed to resolve this confusing situation.

		In the standard scheme, Pakicetus inachus is dated to the late Ypresian, but several experts acknowledge that it may date to the early Lutetian.
		Eocene 1 corresponds to the Ypresian stage, and Eocene 3 corresponds to the Priabonian stage.
		The Ypresian is dated from 56.5 to 50 mya, the Lutetian from 50 to 42.1 mya, the Bartonian from 42.1 to 38.6 mya, and the Priabonian from 38.6 to 35.4 mya.

		At present the Ypresian (late NP 12 and early NP 13) sapropelites are best known and understood.
		During late Early Eocene (=late Ypresian) there is no indication for active deposition of siliceous sediments in basins located on the eastern European platform.
		The fact that the passage between the Chara Sea and the Tethys was active (bringing cold and relatively fresh water to the mid-latitudes) during Late Ypresian emphasises that the idea that the Peri-Tethys was a source area for globally acting deep water may have to be relativated and re-dimensioned.

		Lamna vincenti var inflata was described by Leriche (1905:76) from late Ypresian, and from the early Middle Eocene of Belgium (1905:125).
		The name was used as a species, as opposed to a variety, by Leriche in 1936 (Leriche 1936a: 296) in a paper on reworked basal Oligocene teeth from NE Holland.
		Odontaspis hopei form affinis CASIER 1946 was based on lower anterior teeth from the late Ypresian, in the region of the NP12 of Belgium.

		In Northern Tunisia, the Ypresian Bou Dabbous limy Formation is one of the main exploration targets.
		During the Ypresian, the tectonic activity has controlled the sedimentation resulting in several carbonate lithofacies, from the platform in the south into the basin in the northwest.
		The measured porosity values range from 8 to 16% and the permeability is greatly improved by fracturing/faulting reaching locally 4.5 Darcies in Belli Field.

	SGF Résumé
		The stratigraphically re-situated mammalian material was found in a bone-bed of the level called "Intercalaire Couches II/I" which is dated as early(iest) Ypresian on the basis of its relative stratigraphic position and its selachian fauna.
		At present, the occurrence of several mammal horizons in the "Intercalaire Couches II/I" (and Couche I ?) cannot be excluded, but their age difference seems not significant according to both the associated selachian taxa and the mammalian material, in present data.
		It is the oldest known hyracoidean along with an indeterminate species from the Ypresian of N'Tagourt 2 (Morocco).

		Systematics, biostratigraphy, evolution and faunal dynamics.The phosphate series of Morocco (Early Maastrichtian-Early Ypresian) is well known for its richness in selachian teeth studied by ARAMBOURG in an important monograph in 1952.
		Maastrichtian and Ypresian can be divided into lower and upper parts on the basis of different faunal associations.
		Dynamic and pattern of extinction and faunal revival of selachians are analyzed and permit us to identify two important events of high extinction rates: mass extinctions at the end of the Maastrichtian and selective extinctions (sharks) at the end of the early Ypresian.

		The Eocene is split into four ages: the Ypresian, Lutetian, Bartonian, and Priabonian Ages: the Ypresian Age being the earliest of the four.
		Scientists conclude from the fossil evidences that the Paris Basin during the early Eocene consisted of a wet river forest surrounded by a semi-deciduous forest or deciduous woodland, which was affected by dry periods in the year.
		From the layers of strata corresponding to the earliest Eocene ages, the Ypresian in particular, we can clearly see the many types of species sharing this environment.

		During deposition of the Subathu sediments, there was a minor regression of the Tethys in the early Late Ypresian times.
		The first regression is related to collision between the two plates, which resulted in uplift of the region in the early Late Ypresian times during which the beds of Cordiopsis subathooensis-Turritella subathooensis Zone were deposited.
		The second regression which took place in the Early Lutetian time (47 Ma) is attributed to uplift of the region due to continued collision between the two plates during which beds of Musculus muttali-Parinomya blanfordiana Zone were deposited.

		In this paper an attempt is made to decode these lateral and vertical facies variations in the Late Ypresian Egem Member sands.

		In Central-Eastern Sardinia, terrigenous and mixed deposits were formed during transgressive episodes in Early Eocene times, with Assilina-dominated facies in the early Ypresian of Southern Sardinia, and Nummulites-rich assemblages in central Eastern Sardinia near Orosei in the Late Ypresian.
		The conglomerate clasts, cropping out in several localities of SE Sardinia (Cuccuru’e Flores and the as yet unrecorded occurrences of Su Bandidu and Nurri), testify to the development of carbonate shallow-water environments rich in algae in the Early Paleocene, in the Thanetian and in the late Ypresian, and of larger foraminiferal deposits in the Ypresian.
		The inferred paleoenvironments and the transgressive-regressive successions are interpreted as a close analogue to the tectono-sedimentary history of the eastern Pyrenaic-Provençal region, thus confirming the position of Sardinia within this domain in the Early Tertiary.

		This paper reviews the available stratigraphic evidence from the Himalayan region, and concludes that only in the western Zanskar-Hazara region is the age well constrained as starting in the Late Ypresian (~ < 52 Ma).
		In the most eastern sections of Tertiary rocks thus far recognized within the Tethyan Himalayas north and east of Everest (Mount Qomolangma) normal, shallow shelf-type carbonates extend into the Lutetian, without evidence of a change in sedimentation to the top of the section, so the start of collision must be still younger.
		Along-strike of the Indus Yarlung Zangbo suture thick submarine delta-fan complexes derived from erosion of the Himalayan-Tibet system provide independent estimates that agree with a diachronous collision initiating in the late Ypresian in the west and progressing into and perhaps through the Lutetian in the east.
