The trace fossil Lepidenteron lewesiensis (Mantell 1822) provides an exceptional taphonomic window to diversity of fishes as shown for the Upper Cretaceous of Poland, in the Middle Turonian-Lower Maastrichtian deposits of the Opole Trough, Miechów Trough, Mazury-Podlasie Homocline, and SE part of the Border Synclinorium. Lepidenteron lewesiensis is an unbranched burrow lined with small fish sca...

—The large plagioptychid rudist bivalve Mitrocaprina tschoppi (Palmer) is recorded from the Guinea Corn Formation (Late Maastrichtian) of central Jamaica. This is the first record of this species outside of Cuba. M. tschoppi occurs in rhythm D6 of the Guinea Corn Formation, Macgillavryia Bed 1, together with a rudist assemblage including Praebarrettia sparcilirata (Whitfield), Macgillavryia nic...

The Campanian–Maastrichtian (83–66 Ma) was a period of global climate cooling, featuring significant negative carbon-isotope (δ13C) anomalies, such as the Late Campanian Event (LCE) and the Campanian–Maastrichtian Boundary Event (CMBE). A variety of factors, including changes in temperature, oceanic circulation and gateway opening, have been invoked to explain these δ13C perturbations, but no p...

Abstract The mid-Maastrichtian carbon isotope event (MME), dated at ∼69 Ma, reflects a perturbation of the global cycle that, in part, correlates with enigmatic extinction ‘true’ (i.e., non-tegulated) inoceramid bivalves. mechanisms this are still debated. While both extirpation and MME have been recorded variety deep-sea sites, little is known about their expression epicontinental chalk seas. ...

Maastrichtian argillaceous chalks of the Ghareb Formation are widespread throughout Israel, both in exposures and subsurface. These strata contain a rich fauna foraminifera calcareous nannoplankton, allowing detailed biozonation sediments, which were deposited series basins an outer-shelf to upper-slope environment. The distribution benthonic planktonic from reference section southern Israel is...

Recent field efforts in the Mahajanga Basin of northwestern Madagascar have recovered a diverse Late Cretaceous terrestrial and freshwater vertebrate fauna, including a growing diversity of avialans. Previous work on associated bird skeletons resulted in the description of two named avialans (Rahonavis, Vorona). Other materials, including two synsacra and numerous appendicular elements, represe...

The sedimentary record documenting the northward drift of India (Late Cretaceous to late Early Eocene) has recently provided important clues to the evolution, radiation, and dispersal of mammals. Here, we report a definitive Late Cretaceous (Maastrichtian) archaic ungulate (Kharmerungulatum vanvaleni genus et species nova) from the Deccan volcano-sedimentary sequences exposed near Kisalpuri vil...

Ecological studies suggest that rare taxa are more likely to go extinct than abundant ones, but the influence of abundance on survivorship in the fossil record has received little attention. An analysis of Late Maastrichtian bivalve subgenera from the North American Coastal Plain found no evidence that survivorship is tied to abundance across the end-Cretaceous mass extinction (65 million years...

Radiolitid rudists belonging to the genera Bournonia FISCHER, Biradiolites D’ORBIGNY and Thyrastylon CHUBB are abundant in the Upper Maastrichtian, Titanosarcolites Limestones (Guinea Corn Formation and other formations) of Jamaica. Although there is a large literature on these Jamaican forms (e.g., WHITFIELD, 1897; TRECHMANN, 1924; CHUBB, 1956, 1967, 1971), little information on their microstr...
