“…The opening of the critical N-S Equatorial Atlantic Seaway coincided with a change from an "eddy ocean" to a "thermohaline ocean" [78]. Evidence for this change is provided by North Atlantic nannofossils which evolved from homogeneous Cenomanian distributions with cosmopolitan ranges to heterogeneous Turonian distributions with restricted ranges [40].…”

“…Extensive mid-ocean ridge formation, high crustal heat flow and rapid ocean basin expansion [15]; 5. Major change in ocean circulation from eddy-dominant with widespread cosmopolitan biogeography in the Cenomanian to thermohaline with restricted marine biogeographic zones in the Turonian [40]; 6. Highest sea levels of the Mesozoic with development of major, multiple epicontinental seas, some serving as gateways (e.g., the Western Interior Seaway connecting the tropical Atlantic with polar Arctic) [16,41] and 7.…”

Realistic Paleobathymetry of the Cenomanian–Turonian (94 Ma) Boundary Global Ocean

At present, global paleoclimate simulations are prepared with bathtub-like, flat, featureless and steep walled ocean bathymetry, which is neither realistic nor suitable. In this article, we present the first enhanced version of a reconstructed paleobathymetry for Cenomanian-Turonian (94 Ma) time in a 0.1 • × 0.1 • resolution, that is both realistic and suitable for use in paleo-climate studies. This reconstruction is an extrapolation of a parameterized modern ocean bathymetry that combines simple geophysical models (standard plate cooling model for the oceanic lithosphere) based on ocean crustal age, global modern oceanic sediment thicknesses, and generalized shelf-slope-rise structures calibrated from a published global relief model of the modern world (ETOPO1) at active and passive continental margins. The base version of this Cenomanian-Turonian paleobathymetry reconstruction is then updated with known submarine large igneous provinces, plateaus, and seamounts to minimize the difference between the reconstructed paleobathymetry and the real bathymetry that once existed.

“…Some studies regarding different methods have also pointed late Turonian cooling water (e.g. Voigt, 2000;Voigt and Wiese, 2000;Lees, 2002;Wiese and Voigt, 2002;Forster et al, 2007;Kosták and Wiese, 2011;Linnert et al, 2011). A few minor episodes of cooling water were recorded in the late Turonian/early Coniacian interval (Wells 1-RSS-2 and 1-SCS-3B) as well as another one in the late Coniacian (Well 1-SCS-3B), suggesting a prevalence of warm-water conditions with some cooling water events amid.…”

“…Based on calcareous nannofossil abundance (Bice et al, 2006;Forster et al, 2007;Voigt et al, 2004;Wilson et al, 2002;Linnert et al, 2011), it is known that between Turonian to Maastrichtian times, there was a continuous cooling of seawater, preceded by one of the warmest periods of the Phanerozoic (early Cenomanian -Turonian). In this scenario, global temperatures decreased between 4 -6 °C during the late Campanian (73 -70 Ma) (Li and Keller, 1999).…”

A new species of the brachyuran Ophthalmoplax is documented based upon two specimens collected from shales of the Lodolitas de Aguacaliente Formation, Guadalupe Group, (Cordillera Oriental, Colombian Andes), which represents a regional transgressive event. The small crustaceans were found in the uppermost parasequences with retrogradational stacking pattern, near to the maximum flooding surface (MFS), at the end of the late Campanian Transgressive Systems Tract (TST). This is the oldest record for Ophthalmoplax in America. Morphological affinities with other species of the genus are discussed, including size reduction related with anoxia events and paleotemperature.Keywords: Crustacea, Portunoidea, Ophthalmoplax andina n. sp., Campanian, anoxia, Colombia.
