Early Jurassic foraminiferal assemblages in platform carbonates of Mt. Krim, central Slovenia
Geologija, 2017 During the Early Jurassic, the subtropical carbonate platforms of the peri-Tethys Ocean experienced signifiant changes in their architectures, as well as in their biota compositions.

A bio-chemostratigraphical test of the synchroneity of biozones in the upper Silurian of Estonia and Latvia with some implications for practical stratigraphy [PDF]
Estonian Journal of Earth Sciences, 2015 The paper discusses the reliability of different biozones in terms of their synchroneity when crossing facies boundaries within a sedimentary basin. Graptolite biozones are the most trusted ones, but also biozones based on conodonts, chitinozoans and ...

Biostratigraphic correlation of the western and eastern margins of the Labrador–Baffin Seaway and implications for the regional geology. Fig. 5 [PDF]
Geological Survey of Denmark and Greenland Bulletin, 2016 New analyses of the palynological assemblages in 13 offshore wells on the Canadian margin and six on the West Greenland Margin, in conjunction with onshore data, have led to a new biostratigraphic framework for the Cretaceous–Cenozoic strata of the ...

Evaluating migration hypotheses for the extinct Glyptotherium using ecological niche modeling
Ecography, EarlyView.The formation of the Isthmus of Panama allowed for migrations between the once separated continents of North and South America. This led to one of the greatest documented interchanges of biota in Earth history, wherein an array of species across many groups migrated between the continents.

The Botrychiopsis genus and its biostratigraphic implications in Southern Paraná Basin
Anais da Academia Brasileira de Ciências, 2003 Botrychiopsis has been considered an important floristic element of Westphalian/Artinskian associations of the Paraná Basin. The occurrence of Botrychiopsis in roof-shales of the Rio Bonito Formation in Southern Paraná Basin (Quitéria area), supported by
