	PSFacies Stacking Patterns in a Late Jurassic Bahama-Type Platform Interior, Dinaric Platform, Croatia, by Antun ...
		These Tithonian 3rd order sequences evident on the Fischer plots may be partly equivalent to the four major sea-level cycles depicted on the Haq and Al-Qahtani (2005) chart, but it is not clear how they relate to Hardenbol et al.
		The relatively high Tithonian subsidence rates likely favored relatively complete preservation of precessional cycles with few missing beats, in contrast to the more slowly subsiding parts of the Early Cretaceous where more missing beats are likely.
		The lack of subaerial surfaces in the Tithonian likely is due to the high accommodation rates which even during falling sea-level prevented prolonged emergence of the platform.

		The Paredón field was interpreted as an elongate anticline trending NW-SE and bound by a reverse fault along its NE limit, as well as a series of normal faults with variable orientations (Figure 2B).
		The reservoirs are Lower Cretaceous, Tithonian, and Kimmeridgian in age.
		The Tithonian strata are mainly fine- to medium-crystalline dolomites and a few planktonic wackestone beds.

		Given the probable age of the overlying sequence, it is most likely that the sequence ranges in age from ?Middle Jurassic to Tithonian, although its top may be slightly younger.
		Less tuffaceous claystones overlie the tuff-dominated succession in Well 14/24-1, and may represent the re-establishment of permanent lacustrine deposition, coupled with a decrease in the availability of volcanic material, as a result of drowning of a local source area as lacustrine conditions expanded.
		This unit is probably of Tithonian to Berriasian age, although it is possible that its top lies within the Valanginian.

		Overall, the seeps and oils observed presently in the deepwater GoM are derived mostly from the Tithonian source with various mixes of Oxfordian and MCU contributions.
		The primary source rock is the Upper Jurassic Tithonian with 5-6% TOC and 550-700 HI, and secondary source rocks in the Jurassic Oxfordian (3-4% TOC and 450-550 HI) and Lower Cretaceous (at MCU level with 2-3% TOC and 350-450 HI).
		The primary Tithonian source is at peak expulsion present day, whereas the MCU level source is immature to early mature (no to little expulsion) and the Oxfordian source is post peak expulsion mature.

	Palaeos Mesozoic: Jurassic: Late Jurassic Period (The Malm Epoch)
		In this megafauna sauropods predominated, and were primarily of the diplodocid and camarasaurid families, with a few haplocanthosaurs (especially early on) and the occasional huge Brachiosaur (in fact the Brachiosaurs were bigger here than anywhere else).
		As Dr Bob Bakker has shown, the West Laurasian dinosaurs exhibited a tendency to increase in size, possibly caused by increasingly harsh and arid conditions, so that by the mid Tithonian they were truly gigantic.
		This indicates that the Tithonian could perhaps be subdivided into four ages, the Early, Middle, earlier Late, and Portlandian (later Late), each lasting around one or two million years or so.

		Although rare in Tithonian sediments from Hole 901 A, this morphotype is more abundant and occurs more consistently than the second morphotype (B).

		Retecapsa schizobrachiata is very rare in Tithonian sediments from Hole 901 A. Grün and Zweili (1980) reported this species from the lower Oxfordian; the holotype was recovered from the Upper Cretaceous.

	Mancini et al, 2001
		The Tithonian shales and carbonates are effective source rocks in Mexico and therefore may also have potential in the outer continental shelf (OCS).
		The Upper Jurassic source beds are postulated to be gas and condensate prone in the OCS area of the northeastern Gulf of Mexico, while the Lower Cretaceous source beds are believed to be oil prone.
		Tithonian (Cotton Valley) shales have the potential of serving locally as a confining seal for hydrocarbon accumulations, but these shales are believed to lack the regional lateral continuity, and/or uniformity of thickness and/or lithology to act as effective regional seal rocks.

		New geochemical and sedimentological data obtained from out crop localities examined during the present study is combined with data from previous studies to propose a tectonic evolution model for selected San Pedro del Gallo terrane remnants (SPGTR) occurring southwest of the Walper megashear in northeastern Mexico.
		During the late Tithonian, a worldwide phosphorogenic episode is recorded from deposits occurring along the western margin of continental masses.
		In Mexico, a study of the upper Tithonian phosphorite interval (Unit D; Mazapil and Iturbide remnants) has revealed the presence of five phosphatic zones (MPL-1 to MPL-5) from the Mazapil remnant, and three phosphatic zones from the Iturbide remnant (IPL-3 to IPL-5).

		Away from the graben, shallow marine conditions continued.The rift event was short lived, lasting less than 10 million years and was followed in Tithonian time by post rift sag.
		This sag, combined with a lowering of eustatic sea level, resulted in the exposure and erosion of broad shelfal areas, and deposition of the detritus in the sag basin.
		It was followed by the regional Arabian evaporitic cycle of the late Tithonian, and massive salt deposits filled the sag basin.

		The Tauglboden Basin (Tauglboden Formation and Oberalm Formation) is located in the Osterhorn Group north of the Trattberg Rise and was formed as an elongate trough in the former area of the Late Triassic lagoonal carbonate platform (Tirolicum of the Northern Calcareous Alps, Staufen-Höllengebirgs nappe).
		The dating of these sediments is important for the timing of the closure of the Tethys Ocean (Early Oxfordian to Early Tithonian) and the timing of the nappe thrusting and basin evolution in the central parts of the Northern Calcareous Alps.
		The Tauglboden Formation is overlain by pelagic limestones of the Oberalm Formation (Early Tithonian to Early Cretaceous) intercalated by coarse-grained calcareous turbidites (Barmstein limestones).

	Abstract (Site not responding. Last check: 2007-11-03)
		Environmental changes are reflected by changes in the rock magnetic properties of the sediments.
		Slow accumulation in the Upper Tithonian and around the J/K boundary favoured hematite precipitation.
		Sedimentation increase in the Lower and Middle Berriasian sequence is accompanied by a decrease in magnetic susceptibility, probably related to higher carbonate productivity of micro- and nannoplanklon.

		A detailed taxonomic and biostratigraphic study was conducted on Tithonian calcareous nannofossils from Hole 901A on the Iberia Abyssal Plain, in the Northeast Atlantic Ocean.
		Numerous species thought to have late Tithonian to early Cretaceous appearances are present in these fl shales, possibly indicating that a major radiation and turnover in the nannofossil assemblages occurred during the early Tithonian.
		It is possible that many species originated at high latitudes earlier than has been recognized previously, because of the poor boreal nannofossil record (largely because of unfavorable facies and the limited number of studies).

		Four “remnants” of the San Pedro del Gallo terrane (lower Oxfordian to upper Hauterivian) are examined, concentrating on the outer bathyal to upper abyssal La Caja Formation (lower Kimmeridgian to upper Tithonian).
		Paleogeography, paleocurrent configurations, and the effects of nutrient-rich upwelling waters are proposed as primary limiting factors to the initiation and subsequent termination of bedded phosphorite formation within the San Pedro del Gallo basin during late Tithonian time.
		The petrologic phase of the current investigation has confirmed scanning electron microprobe results that indicate mafic and heavy minerals characteristic of andesitic island arc volcanism have been concentrated within the neritic and bathyal PR-zones from the Mazapil and Iturbide remnants, but are apparently lacking within the deep-water phosphorites.

	Reports Submitted to FAMSI - Carl J. Wendt - Bitumen Sourcing in the Olmec Region
		In the Olmec region, wells in the eastern portion produce petroleum classified into at least two chemically and spatially distinct groupings belonging to the Tithonian oil family (Guzmán-Vega and Mello 1999).
		Figure 9 shows that the distribution pattern of steranes and terpanes obtained from archaeological sample #111 (San Lorenzo, B3, Monument 57), is very similar to that from the field sample #8 collected from Emilio Carranza, and to crude oil produced from Upper Jurassic Tithonian formations (Guzmán-Vega and Mello 1999).
		It is worth noting that although wells in the Olmec region produce petroleum classified into at least two chemically and spatially distinct groupings belonging to the Tithonian oil family, bitumen from seeps in the same region is much more chemically varied, belonging to the Oxfordian, Tithonian, and Tertiary oil families.

	superfamily Diplodocoidea
		The Apatosaurs, Diplodocii, Camarosaurs, Brachiosaurs, Allosaurs, and Stegosaurs all followed this trend, so the early Tithonian dinosaurs were among the most gigantic of these beasts that are known.
		The same tendancy to increased science also occurs at the very end of the Cretaceous (Campanian-Maastrichtian); in both cases this progession to gigantism was followed by a mass-extinction.
		The dating of this formation is uncertain, it is tentatively given as Tithonian [The Dinosauria, p.92].

	The Solnhofen Lithographic Limestone: Lagerstätten Catalogue: University of Bristol
		The first hypothesis seems to be more likely, with carbonate ooze being deposited on the seaward margin of the coral reefs being periodically stirred up by storms and being introduced by suspension into the lagoon, forming a fine mud when it settled.
		The Solnhofen Lithographic Limestone was deposited in the Tithonian age of the Jurassic period, in a small lagoon where water exchange was restricted from the open sea due to an extended platform of shallow water and strong seafloor relief.
		A hot dry climate caused high evaporation rates, which in turn led to extremely saline conditions in the basins and the development of salinity stratification.

		However, because of strong secondary recrystallisation of the limestones in this area, it was impossible to apply the usual method of studying isolated calcareous dinocysts (Rehakova & Michalik, 1996; Ivanova & Keupp, 1999), but an attempt at correlation with species found in thin-sections has been made.
