If anyone has 1hr 6min to kill, https://www.youtube.com/watch?v=ya3w1bvaxaQ is a fun watch. Someone simulated what the shockwave might have looked like.

It was a good day to be a burrowing species that hibernated and ate carrion.

Google search (for those who are still using it) comes up with a funny little Easter egg when you search for "Chicxulub asteroid" or "Chicxulub crater".

Too soon.

TL;DR

> The temporal match between the ejecta layer and the onset of the extinctions and the agreement of ecological patterns in the fossil record with modeled environmental perturbations (for example, darkness and cooling) lead us to conclude that the Chicxulub impact triggered the mass extinction.

which is exactly what everybody believes. Was it still controversial in 2010, the publishing year of the paper?

There are still paleontologists [who?](I do not know; I'm sorry) who would like to substantially credit the Deccan Traps; this appears to be adding stronger analysis to the evidence that it really was the meteor impact.

I think a competing theory was/is that the mass extinction was caused by volcanism of the Deccan-Traps, briefly mentioned in the abstract “…occurred within the time of Deccan flood basalt volcanism in India”. This article seems to confirm a direct relation between the meteorite impact and the extinction with the deccan traps activity possibly serving as a contributing factor.
