description Jan Smit Overview
Jan Smit is a Dutch micropaleontologist known for his extensive research on the Cretaceous-Paleogene (K-Pg) boundary. In 1980, he was part of the scientific team that helped identify the global iridium anomaly in the geological record, providing crucial evidence for the asteroid impact hypothesis. Smit's work has significantly advanced the understanding of mass extinction events, particularly the sudden disappearance of microscopic marine organisms and non-avian dinosaurs 66 million years ago. His research is highly influential among earth scientists studying planetary catastrophes.
