The Ocean Drilling Program (ODP) Carribian Leg found the the entire
basin was covered by an ejecta blanket from the impact right at the K/T
boundary. The Discovery of the ejecta blanket under Florida has forced
their hand in announcing this. My friends in charge of paleo told me
when they got off the boat last year.
Any Cret. based material in crater is based on pollen from
sediment eroded or slumped back in from margin (Crater is 10-15 miles
deep). There is NO QUESTION that the impact is right at the boundary
based on all marine fossils found in cores.
It happened. The consequences need further study.
