Palynostratigraphy of the Upper Cretaceous in Hungary

Cretaceous Research, 1993
Abstract Within the territory of Hungary four sedimentologically different sequences can be distinguished in the Senonian: the Transdanubian Central Range, the 'Gosau', the flysch and the southern Great Hungarian Plain. The most continuous Central Range sedimentary succession can be referred, on the basis of palynology, to the Upper Sanionian-Upper ...

Cretaceous Collembola (Arthropoda, Hexapoda) from the Upper Cretaceous of Canada

Cretaceous Research, 2002
Abstract Previously only one specimen of springtail (Collembola) has been described worldwide from the Cretaceous. The present work reports the results of an examination of seventy-eight collembolan specimens from Canadian Upper Cretaceous amber. Sixty-three specimens have been identified at the generic level, none of which belongs to extant genera ...

An Upper Cretaceous lizard with a lower temporal arcade

Naturwissenschaften, 2008
The reduced lower temporal arcade of the skull and the movable quadrate are the most distinctive features of squamates. Up to now, no exception has been documented for any fossil or extant squamates. We report here a new fossil lizard that possesses a complete lower temporal arcade and an unmovable quadrate.

Gas Detection In Upper Cretaceous Formations

Journal of Canadian Petroleum Technology, 1986
Abstract Hydrocarbon resource companies in the Lloydminster heavy oil region have experienced problems with unwanted gas flows to surface outside production and surface casings. Locating the source of these flows prior to attempting to shut the gas off has proved troublesome. Gas shut-off attempts have therefore had
