There May be as many as 4 more which were large enough to be contributors to the aforementioned areas history. In the presence of any of these events, nothing survives, everything changes. Nucleation events make everything.

Depalma et al....who is et al? The article you commented on is a journalist's preview of the scientific paper released on Monday, April 1st by DePalma and his co-authors. It's about the Tanis fossil site... A seismically induced onshore surge deposit at the KPg boundary, North Dakota pnas.org Tanis (fossil site) en.wikipedia.org Fossil fish from Tanis. The fossil shows microtektites (molten splattered glass droplets) which are a chemical match for ejecta from the Chicxulub meteor crater. The microtektites are concentrated in large numbers in the gill rakers of about 50% of sturgeon and paddlefish fossils, and show that the fish were alive at the time that the impact occurred. Its unlikely that Chicx is responsible, as the 4 events pointed too, are far closer, and each were significant enough in their own right, to have dispersed the microtekties, The microtektites found at the Tanis site match the Chicxulub event, not the other events you mentioned. DePalma and his colleagues have spent years studying the Tanis site, and present compelling evidence to back up their conclusions. I's hard for me to consider your alternate interpretation unless you back it up with evidence.
