At https://archaeologynewsnetwork.blogspot.com/2020/01/in-death-of-dinosaur… … in death of the dinosaurs it was all about the asteroid – not the volcanoes. At last, some realism. Yale assistant professor of geology and geophysics Pincilli Hull, and her colleagues, argue in a paper in the journal Science, that environmental impacts from massive volcanic eruptions in India (the Deccan Traps) occurred before the Cretaceous-Paleogene boundary and therefore did not contibute to the mass extinction of the dinosaurs. For a moment I thought it was an injection of realism but it seems it is not quite that. It would of course be a more realistic position to make them contemporary but she is stumped by uniformitarian geology. Layers of sediment laid down gradually over millions of years rather than rapidly laid down when the asteroid struck the earth. Never mind, one cannot expect Yale to buck the bronco.
It seems the K/T boundary (Tertiary) is now the K/P (Paleogene) boundary event – in recent publications. Means the same thing as the Paleogene is a subdivision of the Tertiary. However, we are also told recent work on the Deccan Traps also pointed towards massive eruptions in the immediate aftermath of the K/T boundary. So, we are getting there, slowly.
