Non-marine Boundary Events in the Newark Basin: IGCP 458 1 Field Guide for Non-marine Boundary Events in the Newark Basin (New Jersey, Pennsylvania, and Connecticut), Eastern United States and their Litho-, Chrono- and Biostratigraphic Context
This field guide is intended to familiarize participants of IGCP 458 with the aspects of the Newark and Hartford rift basins relevant to the non-marine Triassic-Jurassic boundary and its larger context. We will visit 27 stops that illustrate these the basins' range of sedimentary and igneous environments and paleobiological assemblages, focusing on their significance to the understanding of glo...

متن کاملThe nonmarine Triassic–Jurassic boundary in the Newark Supergroup of eastern North America
For the last three decades, the position of the Triassic–Jurassic boundary (TJB) in nonmarine strata has largely been based on its palynostratigraphic placement just below the oldest basalts of the Central Atlantic magmatic province (CAMP) in the Newark Supergroup of eastern North America. This boundary, however, is demonstrably older than the TJB as it is defined in marine strata. Thus, the pa...
متن کاملMesozoic marine tetrapod diversity: mass extinctions and temporal heterogeneity in geological megabiases affecting vertebrates.
The fossil record is our only direct means for evaluating shifts in biodiversity through Earth's history. However, analyses of fossil marine invertebrates have demonstrated that geological megabiases profoundly influence fossil preservation and discovery, obscuring true diversity signals. Comparable studies of vertebrate palaeodiversity patterns remain in their infancy. A new species-level data...
متن کاملTriassic–Jurassic boundary events: Problems, progress, possibilities
As for most geological period boundaries, the Triassic–Jurassic (T–J) transition, ∼200 million years ago, was a critical juncture in Earth history during which profound biotic and environmental changes took place. Early comparisons with the end-Cretaceous extinction and the involvement of extraterrestrial impact have now largely, although not entirely, given way to more Earthbound explanations ...
