Analysis of tetrapod footprints and skeletal material from more than 70 localities in eastern North America shows that large theropod dinosaurs appeared less than 10,000 years after the Triassic-Jurassic boundary and less than 30,000 years after the last Triassic taxa, synchronous with a terrestrial mass extinction. This extraordinary turnover is associated with an iridium anomaly (up to 285 parts per trillion, with an average maximum of 141 parts per trillion) and a fern spore spike, suggesting that a bolide impact was the cause. Eastern North American dinosaurian diversity reached a stable maximum less than 100,000 years after the boundary, marking the establishment of dinosaur-dominated communities that prevailed for the next 135 million years.

"the Jurassic Period, which lasted millions of years."

Prove it.

Hahaha! Oh, I see, I see where they’re going with this-—buncha friggin’ assholes....

I thought we were hit by an iridium-rich meteor, and that that was settled science.

... rather than a change in CO2 in the atmosphere (which causes today's climate change)...

Oh dear...that gurgling sound you hear is someone's credibility circling the drain.
