A massive inpact is the most plausible. 300,000 years is a hickup. The fact remains that above the Cretaceous-Tertiary boundary the fossil record of Dinasuars ends, and the iridium has been found at that layer all over the planet.

...and iridium is not a substance that occurs naturally, in abundance, on Earth.

My theory is that the Caribbean is the site/crater of a huge meteor impact, large enough to kill off dinosaurs.

I'll agree with you Canada, the BFR got the Dinos if there was extensive volcanism it too was triggered by the 10KM monster.

"The fact remains that above the Cretaceous-Tertiary boundary the fossil record of Dinasuars ends, and the iridium has been found at that layer all over the planet." Yup. Along with an ash layer from all the trees that burned.
