There I [...]

It used to be simple: big rock from space killed the dinosaurs (and others) by creating an ecological catastrophe with a sun-blocking dust cloud, a rapid drop in temperatures, local firestorms, etc. As with all hypotheses, the more information we gather the more interesting the problem becomes. Now there is the suggestion there may have been two impacts. The Boltysh Crater in Ukraine is now paired with the better known (and much larger) Chicxulub Crater in Mexico. The implication is that there may have been more than just two impacts. This summer I was introduced to this new idea by a curious set of clays at the Cretaceous-Paleogene boundary in The Netherlands. [...]
