THE K-PG IMPACTOR WAS LIKELY A HIGH VELOCITY COMET
PDFBy reassessing and reconciling geo-physical and geochemical evidence for the nature of the K-Pg impactor, we can demonstrate that 99.99% of potential impactor candidates that are coherent with both the geophysical and geochemical data are comets (and 95% are long period comets). This is at odds with the commonly held view that the impactor was a much larger, more slowly travelling asteroid, opening major new directions for the investigation of the K-Pg impact and its effects.
