Spread out over 127,000 generations.

Actually, it would appear that they used real math in this estimate.
You know, that evil racist math.
Kind of a shock

CO2 was estimated to be 15% higher than now and the planet survived.

There had to be more than conserving all the Dino oil we have!

CO2 was double so vegetation density was likely double today's.
Oxygen levels were 50% more, so there was a lot of fat but muscular plant eaters to eat.
If it wasn't for the Cancun Comet... We'd be all rooting for the Gorn to kick that Space Ape Kirk's Ass.

About 1 in 80 million T-Rex’s became fossilized. So something must have been eating them before the meteor turned dinosaurs into fossils. Maybe a dinosaur with a better jab and a longer arm reach. I say dig for poop with T-Rex DNA in it. I wish I was young enough to apply for a grant.

2.5 BILLION?
They should have wiped-out all other dinos over that time span.
Sounds fishy to me.

The total was over millions of years, so not very crowded.

Is is for a species.
Unless the author meant genus.

Over the years I’ve read a bit of Geology.
This planets climate has been all over the place prior to the Industrial Age.
Trees at the South Pole, river beds in the Sahara, dried up Mediterranean Sea, rocks from the North Pole found at the equator (almost total ice age), land bridges from Europe to U.K, Asia to Japan, Eurasia to N. America.
Man made global warming. Hooey.
