Chance mutation cannot explain what we see in the evolutionary record. Something is driving it.

Most interesting new discovery in that is they found the tail of another dino with a T-Rex tooth stuck inside it. The wound had healed, so it means the T-Rex tried to chomp on it while it was alive.

The sea of billions and billions of T Rexes.

it’s only about 1/3 the population of humans alive today.

For an animal that was more than 50 times the mass of an average human.

It was a joke, sarcasm.

apparently you missed the “over time” qualifier in the article. Only about 20,000 standing population.

Apex predators always have a smaller population than their prey or famine and cannibalism are next.

Humans figured out a better way.

“The sea of billions and billions of T Rexes.”

You misread the headline ...

Wow, think how many things died in the jaws of those monsters.

The horror! The horror!

“Pfft, pikers. There are 7.5 billion humans right now all at once.”

Not in North America. If you believe this Paleo-nonsense you couldn’t have thrown a rock back then without hitting a T-Rex.

Sharks don’t need arms either. They just swim up and take a bite. If T-Rex had any kind of sprinting ability it would have made for an ambush predator against very large herbivores. But as with most meat-eaters they swing between predator and scavenger.

“If T-Rex had any kind of sprinting ability...”

One scientists I read said he did, wrote that T-Rex was a roadrunner from hell.

This sounds a bit like Howard Wolowitz’ calculation of how many single women were in LA area bars on any Friday night and his chances of scoring.

I instinctively knew BEFORE reading the article there is just no practical way Billions of T-Rex’s could inhabiting at the same time in North America. Of course over 2 or 3 million years that is quite possible.

If humans survive 2 million more years, what will be the cumulative population over that time? Could be beyond the scope of a 64 bit based computer in integer form.

A little help here, I seem to have missed the part where the discuss the T Rex life expectancy and population curve data.

So they don’t know the population accurately.

And they don’t know the range accurately.

And they don’t know the duration accurately...

So I would say their accuracy is +/-ten trillion.

I remember that. Bakker.

Paleontologist Robert Bakker memorably described T. rex as "the 20,000-pound roadrunner from Hell"
