Broad-Scale Patterns of Late Jurassic Dinosaur Paleoecology

open access: yesPLoS ONE, 2010
There have been numerous studies on dinosaur biogeographic distribution patterns. However, these distribution data have not yet been applied to ecological questions. Ecological studies of dinosaurs have tended to focus on reconstructing individual taxa, usually through comparisons to modern analogs.

Pangean (Late Carboniferous–Middle Jurassic) paleoenvironment and lithofacies

open access: yesPalaeogeography, Palaeoclimatology, Palaeoecology, 2000
Abstract Six time interval maps were constructed that depict the plate tectonic configuration, paleogeography and lithofacies for Pangea from the Late Carboniferous through the Middle Jurassic. Generally, the individual maps illustrate the conditions present during the maximum marine transgressions of higher frequency cyclicity within the Absaroka ...
