New verdict in scientific whodunit: Dino-killing space rock was a comet

From article:

Quote: Some 65 million years ago, a big rock -- a very big rock -- slammed into the southwest portion of the Yucatan Peninsula in Mexico, creating a 110- to 180-mile crater and triggering a biological catastrophe that wiped out more than half the Earth's species, including the dinosaurs.

In 2010, an international panel of scientists ruled out alternative explanations as they coalesced around the theory that the space rock impact was responsible for this cataclysmic event. However, they debated whether the crater was produced by a comet or an asteroid.

New research now points to a comet as the culprit.

I question the general assumption that felines are inherently deficient in the area of grammar and sentence structure.

The debate was:

Slow rock (asteroid) or fast snowball (comet).

The old theory was it was big and slow, the new theory is it was fast and small.

The butler did it.

Was reading about this the other day:
Quote:Lappajärvi is a lake in Finland, in the municipalities of Lappajärvi, Alajärvi and Vimpeli. It is formed in a 23 km (14 mi) wide meteorite crater. The age of the crater is estimated to be 73.3 million years old (±5.3 million years)—the upper Cretaceous period.

Absolutely beautiful area. There's a road right by it and it's worth taking.
