New biostratigraphic and chemostratigraphic data from the Chicotte Formation (Llandovery, Anticosti Island, Laurentia) compared with the Viki core (Estonia, Baltica) [PDF]
Due to the lack of biostratigraphically useful graptolites in the crinoidal and reefal Chicotte Formation on Anticosti Island (Québec, Canada), the precise chronostratigraphic position of the formation is not known. New stable carbon isotope and conodont

Graptolites of the Šárka Formation (Middle Ordovician, Prague Basin) and their stratigraphical significance [PDF]
Graptolites are one of the significant groups of stratigraphic index fossils in the Early Palaeozoic. They are used to determine the boundaries between bio- and chronostratigraphical units and to correlate them both on a regional and the global scale ...

Graptolites – stratigraphic tool in the exploration of zones prospective for the occurrence of unconventional hydrocarbon deposits [PDF]
In connection with the exploration of zones prospective for the occurrence of unconventional hydrocarbon deposits, numerous studies of source rocks have been conducted in Poland. Stratigraphic examinations are among the basic elements.

The world`s oldest crustoid graptolites from the Upper Tremadocian of Poland [PDF]
The Crustoidea are an order of sessile basic graptolites that are morphologically intermediate between the extant genus Rhabdopleura (Rhabdopleuroidea) and the extinct sessile order—the Dendroidea (Kozłowski 1962, 1966; Bulman 1970; Urbanek 1986). So far
