Chicxulub misses out on mass extinction

So say National Science Foundation researchers after investigating the crater and debris around it. They’re looking for a later impact.

Another interesting (and rocky) fender-bender happened in Australia, at a place called Bedout, off Hedland and Broome where signs of a potential oil find were investigated & found to contain feldspar glass & other shock-impact minerals (maskelynite) atypical of vulcanism. Their conclusion was that it may have been the cause of a major (70% of all lifeforms) Permian/Triassic extinction.
