Marine organisms have occupied hard substrates since the Archaean. Shells, rocks, wood
and sedimentary hardgrounds offer relatively stable habitats compared to unconsolidated …

Abstract The Early Jurassic Toarcian oceanic anoxic event (T-OAE) was marked by
deposition of organic-rich sediments and a pronounced negative carbon-isotope excursion …

The early Toarcian (eTo) and Cenomanian–Turonian (C–T) mass extinctions are
comparable from a wide range of scales and perspectives. From a broad standpoint, their …

Recent studies of contemporary basins and ancient strata have provided a basis for
expanding and refining early oxygen-related marine biofacies models. New observations …

In this complete and thorough update of Arthur Boucot's seminal work, Evolutionary
Paleobiology of Behavior and Coevolution, Boucot is joined by George Poinar, who …

An attempt is made to determine the amount and rate of sea-level change for two major
events in the latest Triassic to early Jurassic, both of which are associated with mass …

Presented for the first time in this paper are the results of a detailed multi-proxy investigation
conducted on the Hangenberg Black Shale (HBS) from the Polish part of the Laurussian …

We have reinvestigated the marine mass extinction interval that occurred during the early
Toarcian, which was a time of widespread marine anoxia. The ranges of marine benthic …

The current knowledge about the ammonoid/habitat relation is reviewed and in part newly
interpreted. The autecology of ammonoids, such as ontogeny and habitat, based on …

Abstract The majority of British Jurassic dysaerobic and anaerobic facies (black shales)
accumulated in rapidly subsiding basinal areas. Exceptionally, during the earliest stages of …
