Serratolamna 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 کاملMorphology, Microstructure and Stratigraphy of Some Late Cretaceous Radiolitid Rudists from Jamaica
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...
متن کاملUpper Cretaceous Foraminifera from Japan
IN THIS PAPER the discovery in Japan of smaller Foraminifera from the Upper Cretaceous strata is recorded for the firsi: time. This contribution, in addition to its specific biostratigraphic application in Japan, has further interest by reason of its extension of the geo. graphic range ,of the widely distributed Cretaceous pelagic foraminiferan, Globotruncana. In the north Pacific region, Globo...
متن کاملA Cretaceous mammal from Tanzania
We report here the discovery of a Cretaceous mammal from the “Red Sandstone Group” of southwestern Tanzania. This specimen is one of only a very few Cretaceous mammals known from Gondwana in general and Africa in particular. The specimen consists of a short, deep left dentary that bore a large, procumbent central incisor, and five single−rooted, hypsodont cheek−teeth. The specimen is very tenta...
متن کاملCarnivorous fungi from Cretaceous amber.
Carnivorous fungi dating back to the age of the dinosaurs have been found fossilized in circa-100-million-year-old amber. The fossil fungi used hyphal rings as trapping devices and are preserved together with their prey, small nematodes. The excellent preservation in amber allowed comparison with extant groups: On the basis of the mode of ring formation and the dimorphic mode of life, the fossi...
