Upper Cretaceous Shoreline in Utah

Geological Society of America Bulletin, 1926
Introduction It is the purpose of this paper to record briefly stratigraphic data collected in 1924 and 1925 along the western margin of the Wasatch Plateau ; to correlate it with data previously recorded for the other regions to the south and north; and to interpret on the basis of the correlation the probable position of the Upper Cretaceous ...

Upper Cretaceous Fossils

Quarterly Journal of the Geological Society of London, 1930
The fossils here described were collected by Mr. Francis Rodd in the South Central Sahara in 1927. They were obtained from ‘a stratum of fossil shells under limestone’ at In Nuguren (19° 5' lat. N., 8° 20' long. E. approximately). The locality is marked on the accompanying map (Pl. XLI).

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 ...

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

Upper Cretaceous Bolivinoides Guide Forms

Micropaleontology, 1958
"The development of the series Bolivinoides strigillata- decorata-australis-gigantea in the upper Cretaceous of Belgium is followed. In a nearly continuous sequence of formations, the group is found to increase the number of pustules on the last-formed sutures from two to nine. This continuous increase can be used as a stratigraphic tool in working out
