(Newser) – It’s just one horn, not quite a foot and a half long, but scientists say a newly discovered fossil could clinch the theory that a falling asteroid wiped out the dinosaurs. Skeptics of the scenario have always pointed out that we’ve found no dinosaur fossils dated within the 3 million years before the meteor hit, the Telegraph explains. Until now, that is.

Because that single horn, which might have belonged to a Triceratops or a related species, was found just inches below the Cretaceous-Tertiary boundary at which dinosaurs vanish from the fossil record. That indicates that dinosaurs existed right up until the end of the Cretaceous, supporting the idea that they died suddenly—and closing the so-called “3 million gap.”

What is wrong with creationist believing the meteors killed all the dinosaurs??? Would God not have to use some kind of tool??

i hope something conclusive comes from this. i'm quite tired of school teachers telling children "i don't know." but then organized religion will say asteroids can cause floods too and Deep Impact will become dogma.

scientists tend to take tiny bits of evidence and make huge gigantic assumptions from them...maybe it was an asteroid...maybe it was a bunch of them....maybe it was a comet or a catastrophic caldera...something killed them though...unless...they are still here...zipping around in them flying saucer things
