New dating evidence shows that the Russian rock record overlaps the North American record, and the gap is closed. We can study the story of change in terrestrial ecosystems through the Permian without a major lack of knowledge.
Great ! I am eager to know what are these new evidence (biostratigraphy ? radiometry ? magnetostratigraphy ?) Is there anyone who would have access to the pdf, by any chance ? Thanks in advance, Jocelyn :-)
