The ancient asteroid that slammed into the Gulf of Mexico and
purportedly ended the reign of the dinosaurs occurred 300,000 years
too early, according to a controversial new analysis of melted rock
ejected from the impact site.

There was once a Nova program on PBS made before the Yucatan crater
was found, and it suggested that perhaps Iceland was caused by the
asteriod that killed the dinosaurs.

Iceland happens to be on the mid-ocean ridge, in an especially thin
part of the crust. The suggestion was that perhaps an asteriod punched
througth and created the volcanoes that resulted in Iceland. And
Iceland is about 65 million years old, just the right age.

IIRC there was also some speculation about two "craters" in the sea bed
off the carolinas. However Chicxulub was found and it is the correct
age and an enormous crater so without some convincing counter evidence
that is the what I'm pretty sure caused the K-T extinction event.

Do you remember the age of the ones off the Carolinas? There's also a
crater about half Chicxulub's size at the mouth of the Chesapeake Bay,
but it's more recent, about 35 million years old.
