An Upper Triassic (Upper Norian-Rhaetian) carbonate complex, composed of open marine to reefal deposits, has been investigated for the first time in Eastern Sulawesi. The age is based on the occurrence of benthic foraminifera, and also of the Upper Sevatian to Rhaetian conodont Misikella posthernsteini Kozur and Mock.

Stratigraphy of the Knife Lake series in the Kekequabic-Ogishkemuncie area, Minnesota
Geological Society of America Bulletin, 1939Detailed studies of the “Knife Lake series” in the Vermilion district of northeastern Minnesota in the vicinity of Kekequabic and Ogishkemuncie lakes reveal two series of continental sediments separated by an unconformity of considerable magnitude. The sediments of the Knife Lake series, in contrast to the Lower Huronian series of the south shore of ...

The Elemental Stratigraphy of the South Caspian Lower Pliocene Productive Series
2014This study is the first attempt to quantify the chemical stratigraphy of the South Caspian Productive Series sediments, based on their macro- and microelemental compositions. The results show a good correlation between the content of some of the elements and the lithology of studied sediments, which allows chemostratigraphic units to be distinguished ...

High resolution trilobite stratigraphy of the Lower–Middle Ordovician Öland Series of Baltoscandia
Geological Magazine, 2012AbstractThe first ever list of the regional Öland Series (Tremadocian to mid Darriwilian) trilobites and agnostids from the whole of Baltoscandia is compiled. The study includes revision of systematics as well as vertical and horizontal distribution. This is necessary because of the uneven state of knowledge, some faunas having being studied recently ...

THE STRATIGRAPHY OF THE CARADOC SERIES IN THE CROSS FELL INLIER
Proceedings of the Yorkshire Geological Society, 1959Summary The rocks of the Caradoc Series in the Cross Fell Inlier have been re-examined and their faunas, almost exclusively of shelly type, collected systematically. As a result a fairly detailed correlation with the stages of the south Shropshire succession is now possible.

Debatable questions of Boreal Triassic stratigraphy: boundary between middle and upper series
Russian Geology and Geophysics, 2008Abstract Various opinions on the position of the Middle/Upper Triassic boundary have been concisely reviewed. The lower boundary of the Carnian Stage is accepted at the base of the Trachyceras aon Zone. The recentmost data on biostratigraphy of boundary beds of the Ladinian and Carnian Stages of the Southern Alps, Himalayas, British ...

Strontium isotope stratigraphy of the Comanchean Series in north Texas and southern Oklahoma
Geological Society of America Bulletin, 2003Pioneering studies in north Texas and adjacent Oklahoma played an important role in the paleontologic and stratigraphic development of the Cretaceous in North America. We have used the results from 135 strontium isotope analyses from fossils and rocks collected from 43 sites to define the "middle" Cretaceous path of seawater 8 7 Sr/ 8 6 Sr during ...

Abstract A study of benthic Foraminifera from the Toarcian in Quercy (Aquitaine Basin, France) shows that micropaleontological assemblages are influenced by sea level changes. The percentages of coiled, and straight Nodosarridae (Lenticulina, Citharina) differ during periods of low sea level to high sea level.
