“…However, considerable temporal variation is documented throughout the Period, and tropical sea-surface paleotemperatures are particularly poorly understood. Global paleotemperature curves from a variety of locations (central Pacific, Australia, Antarctica, southern South Atlantic, northern and southern Europe) are in broad agreement and suggest a relatively cool mid and late Aptian (presence of mid-Aptian glendonites in Arctic basins, Kemper, 1987) and early to mid-Albian, with temperatures rising through the late Albian and the Cenomanian to peak in earliest Turonian time and then decline (Douglas and Savin, 1975;Arthur, Dean, and Schlanger, 1985;Kemper, 1987;Kolodny and Raab, 1988;Barrera, 1994;Ditch-field, Marshall, and Pirrie, 1994;Jenkyns, Gale, and Corfield, 1994;Frakes, Probst, and Ludwig, 1994;Pirrie and others, 1995;Huber, Hodell, and Hamilton, 1995;Podlaha, Mutterlose, and Veizer, 1998;Clarke and Jenkyns, 1999). The distribution of Classopolis pollen, thought to derive from a warmth-loving conifer, across the former Soviet Union equally suggests that the latest Aptian and early Albian were particularly cool compared with the ensuing Cenomanian stage (Vakhrameyev, 1982).…”

ABSTRACT. Many guyots in the north Pacific are built of drowned Cretaceous shallow-water carbonates that rest on edifice basalt. Dating of these limestones, using strontium-and carbon-isotope stratigraphy, illustrates a number of events in the evolution of these carbonate platforms: local deposition of marine black shales during the early Aptian oceanic anoxic event; synchronous development of oolitic deposits during the Aptian; and drowning at different times during the Cretaceous (and Tertiary).Dating the youngest levels of these platform carbonate shows that the shallow-water systems drowned sequentially in the order in which plate-tectonic movement transported them into low latitudes south of the Equator (paleolatitude ϳ0°-10°south). The chemistry of peri-equatorial waters, rich in upwelled nutrients and carbon dioxide, may have been a contributory factor to the suppression of carbonate precipitation on these platforms. However, oceanic anoxic events, thought to reflect high nutrient availability and increased productivity of planktonic organic-walled and siliceous microfossils, did not occasion platform drowning. Neither is there any evidence that relative sealevel changes were the primary cause of platform drowning, which is consistent with the established resilience of shallow-water carbonate systems when influenced by such phenomena.Comparisons with paleotemperature data show that platform drowning took place closer to the Equator during cooler intervals, such as the early Albian and Maastrichtian, and farther south of the Equator during warmer periods such as Albian-Cenomanian boundary time and the mid-Eocene. Initiation of one carbonate platform relatively close to the Equator, at paleolatitudes more northerly than those where others drowned, took place during the cool early mid-Aptian. These correlations are in accord with an interpretation that excess warmth in shallow peri-equatorial waters proved inimical for many carbonate-secreting organisms living on the platforms, allowing subsidence or eustatic sealevel rise to outpace sedimentation and guyots to form. A parallel may be drawn with the recent phenomenon of coral and foraminiferal bleaching, whereby photosynthetic symbionts succumb to prolonged high temperatures (G30°C) and the host organism dies. The fact that most Cretaceous guyots reside in the north Pacific may not be solely related to the age-distribution pattern of ocean floor but to their having run the gauntlet of a difficult and dangerous passage across the Equator. North Pacific guyots are relics from the Cretaceous (and Eocene) ''greenhouse'' Earth.

“…Trends in mid-Cretaceous records have been illustrated in several low-to moderateresolution datasets from both deep-sea and outcrop sections (e.g. Clarke & Jenkyns 1998;Stoll & Schrag 2000 (Douglas & Savin 1973, 1975Barrera 1994 records suggests that the North Atlantic basin was either filled with overturning surface waters or that the planktonic foraminifera chosen for analysis grew in subthermocline waters. We think it most likely that the occasional similarity in deep and surface 8180 reflects variability in the intensity of surface stratification, as the 8180 gradient swings between c. 0.5%o and nearly 2%o during OAE l b (c. 112 Ma).…”

Ocean Drilling Program (ODP) Leg 171B recovered continuous sequences that yield evidence for a suite of ‘critical’ events in the Earth’s history. The main events include the late Eocene radiolarian extinction, the late Palaeocene benthic foraminiferal extinction associated with the Late Palaeocene Thermal Maximum (LPTM), the Cretaceous-Palaeogene (K-P) extinction, the mid-Maastrichtian event, and several episodes of sapropel deposition documenting the late Cenomanian, late Albian and early Albian warm periods. A compilation of stable isotope results for foraminifera from Leg 171B sites and previously published records shows a series of large-scale cycles in temperature and δ13C trends from Albian to late Eocene time. Evolution of δ18O gradients between planktic and benthic foraminifera suggests that the North Atlantic evolved from a circulation system similar to the modern Mediterranean during early Albian time to a more open ocean circulation by late Albian-early Cenomanian time. Sea surface temperatures peaked during the mid-Cretaceous climatic optimum from the Albian-Cenomanian boundary to Coniacian time and then show a tendency to fall off toward the cool climates of the mid-Maastrichtian. The Albian-Coniacian period is characterized by light benthic oxygen isotope values showing generally warm deep waters. Lightest benthic oxygen isotopes occurred around the Cenomanian-Turonian boundary, and suggest middle bathyal waters with temperatures up to 20 °C in the North Atlantic. The disappearance of widespread sapropel deposition in Turonian time suggests that sills separating the North Atlantic from the rest of the global ocean were finally breached to sufficient depth to permit ventilation by deep waters flowing in from elsewhere. The Maastrichtian and Palaeogene records show two intervals of large-scale carbon burial and exhumation in the late Maastrichtian-Danian and late Palaeocene-early Eocene. Carbon burial peaked in early Danian time, perhaps in response to the withdrawal of large epicontinental seas from Europe and North America. Much of the succeeding Danian period was spent unroofing previously deposited carbon and repairing the damage to carbon export systems in the deep ocean caused by the K-P mass extinction. The youngest episode of carbon exhumation coincided with the onset of the early Eocene Warm Period and the LPTM, and has been attributed to the tectonic closure of the eastern Tethys and initiation of the Himalayan Orogeny.

During the early Maastrichtian an assemblage rich in large foraminifera, mostly composed of orbitoidal foraminifera, developed in the shallow-water deposits of the Cárdenas Formation (Valles-San Luis Potosí Platform, Mexico). Among them, the most abundant is Lepidorbitoides minima, some of which display a morphologically abnormal test consisting of polyvalent forms, conical tests and budding, which could be induced by abrupt changes in environmental factors. The occurrence of the abnormalities preceded the demise of this species and of all the larger foraminiferal association in the upper part of the Gansserina gansseri Zone (early Maastrichtian). The abnormalities could be induced by environmental stress, probably related to interplay of different events such as increased terrigenous input and the transition to deeper facies due to Laramide tectonic instability before the K/P boundary.A late Maastrichtian community of dwarfed planktic foraminifera composed of Trinitella scotti Brönnimann, Plummerita reicheli Brönnimann, Rugoglobigerina cf. macrocephala Brönnimann, Rugoglobigerina hexacamerata Brönnimann, Heterohelix punctulata (Cushman), Pseudoguembelina costulata (Cushman), Pseudotextularia intermedia de Klasz, Globigerinelloides asperus Bolli, Guembelitria cretacea Cushman, Rugoglobigerina rugosa (Plummer), Rugotruncana sp., Globotruncanita stuarti (de Lapparent), and Globotruncana arca (Cushman) developed in the upper part of the sequence. This uncommon morphology could also be related to the highly stressed paleoenvironmental conditions related to global climatic change and local tectonic activity. Associated with this planktic assemblage is a deeper-water dwarfed benthic foraminiferal community composed of Gyroidinoides nitidus (Reuss), Coryphostoma incrassata (Reuss), Pseudouvigerina plummerae Cushman, P. cretacea Cushman, Bolivina cretosa Cushman, Planulina texana Cushman and Cibicides harperi (Sandidge).Keywords: Abnormal foraminifera tests, Lepidorbitoides minima, dwarfed planktic foraminfera, Maastrichtian, Cárdenas Formation, Valles-San Luis Potosí Platform.
