Re: What really happened 65 Ma ago (not a joke)
I seem to recall reading somewhere that there are sedimentary deposits
between the basaltic layers of the Deccan Traps that contain dinosaur
fossils. Has the iridium layer been recorded anywhere in the Deccan
Yes, right above the last dinosaur fossils, and between two lava flows.
There is also reports that the impact crater has a different date to the
iridium layer. Is Gerta Keller a lone voice?
Yes. She has found Cretaceous sediments in a drill core from the crater --
but the vertical walls of a primary crater that is tens of km deep are
expected to fall down!
