How were scientists able to come to the (pretty much universally accepted) conclusion that it was a meteor that killed the dinosaurs when no one was around to witness it?

Question

Is it even remotely possible it was something else that happened around the same time?

Answer 1

Most scientists agree that birds are in fact feathered dinosaurs. They are descended from a small bipedal therapod. So you could say that dinosaurs did not go extinct exactly. The iridium layer that can be seen is sometimes called the kt boundary. The impact itself and the shock wave it produced killed a lot of stuff to be sure but it did not cause the mass extinction though. the massive amount of matter that was hurled into the atmosphere blocked the sun caused climate change cooled the planet killed of a lot of plants etc. it is pretty widely accepted but new theories come along every so often.
