چکیده
—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 nicholasi (Whitfield), Chiapasella trechmanni Mitchell & Gunter, Plagioptychus zansi Chubb, Titanosarcolites sp.; Titanosarcolites cf. alatus Chubb and Antillocaprina cf. occidentalis (Whitfield). The pallial canals of the Jamaican specimens are identical to the Cuban material, but the Jamaican specimens are larger (about one and a half times the

New details on its wall microstructure are provided. The microfacies is represented by bioclastic wacke-/pack-/grainstones with ...
متن کاملSerratolamna serrata (Agassiz) (Pisces, Neoselachii) from the Maastrichtian (Late Cretaceous) of Jamaica
Three teeth of the shark Serratolamna serrata (Agassiz) from the Guinea Corn Formation (Central Inlier) represent the first recorded occurrence of fossil sharks from Cretaceous rocks of Jamaica. This occurrence increases the known palaeogeographical distribution of S. serrata, which appears to have been global. This species is largely known from the Upper Maastrichtian, which helps confirm the ...
متن کاملUpper Cretaceous Petroleum System of Northwestern Persian Gulf
Three well - known source rocks of the Zagros basin and the Persian Gulf are Mesozoic in age.The Jurassic Sargelu, Albian Kazhdumi and Neocomian-Coniacian Garau formations have charged the Cretaceous reservoirs of this area. The northwest part of the Persian Gulf is strongly influenced by two major N-S trending paleohighs (Hendijan- Bahregansar-Regesafid-Izeh and Kharge- Mish) and surrounding p...
متن کاملAbundance not linked to survival across the end-Cretaceous mass extinction: patterns in North American bivalves.
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...
متن کاملPlanktonic Foraminifera Response to Sudden Global Warming in Late Maastrichtian, a Case Study from Ziyarat-Kola, Central Alborz, Iran
An abrupt global warming event has been recorded in many parts of the world in sediments of Latest Maastrichtian age between 65.45-65.10 Ma. This warm event was documented here at a section near Ziyarat-kola in Central Alborz based on analysis of planktonic foraminifera. An unusual abundance of normally large-size species such as Globotruncana arca, Globigerinelloides subcarinatus, Pseudoguembe...
