Plants at the Cretaceous-Paleogene boundary

Jud , Nathan A [1].

Plants at the Cretaceous-Paleogene boundary.

The end-Cretaceous extinction event had profound and lasting influence on the evolution of life on earth. The evidence that the asteroid impact was the primary driver of extinction worldwide is clear, but climate change and the Deccan volcanism may have had important effects on vegetation during the latest Cretaceous and early Paleocene as well. This critical interval is best documented for land plants in Western North America, but evidence for geographic variation in the severity of extinction and the dynamics of recovery is emerging, especially from the southern continents. The main goal of this colloquium is to share results of research related to the diversity of land plants during the Maastrichtian and Paleocene. Contributions may focus on ecological and/or systematic perspectives and investigate the identity of K-Pg boundary taxa, global or regional vegetation patterns during the latest Cretaceous, or how survivorship varied with geography, phylogeny, or functional traits. By organizing a colloquium with diverse approaches to understand similar age floras from around the world, we aim to significantly improve our comprehension of the effects of major ecosystem perturbation events on land plants.
