The Dinosaurs That Gave T-Rex Nightmares

The Dinosaurs That Gave T-Rex Nightmares

Life in Late Cretaceous North America, between 68 and 66 million years ago, was a brutal arena of survival even for the mighty Tyrannosaurus rex. Far from being invincible, T. rex faced a deadly gauntlet of rivals: armored giants capable of delivering fatal blows, opportunistic predators waiting to exploit any weakness, and cunning scavengers ready to challenge its supremacy.
The sprawling landscapes of the Hell Creek Formation and beyond were filled with creatures that didn’t just endure—they thrived, evolving sophisticated defenses and strategies that could turn the tables on the so-called king. These weren’t helpless prey, They were formidable survivors, some of whom could prove to be a T. rex’s worst nightmare.

6:48 You're mentioned the size of E. regalis, E. annectens were huge, normally 13 m length and 7-9 tonnes in mass, we're some larger ones equal to size of shantungosaurus about 15m long and 15 tonnes heavy.

4:20 what documentary was this with the red t rex??? That looks way to serious 🔥🔥🔥

[giri_]

2:26 You cannot neglect the ridiculous bite of t rex. This is why t rex evolved to have this strong bite.

It was not a mereor that killed the dinosaurs. It was gravity. When Earth was a satalite of Saturn, it had 1/3rd its gravity, the solar wind is charging earth with 100 volts per square meter, and electricity has mass. E=mc2.

I love getting ideas to play "The Isle"...

8:52 Ridiculous. Adult and Sub adult rexes can literally bite the pachy in halves with one bite.

[giri_]

5:31 Adult rexes were nearly 10 tonnes on average.

11:53 Juvenile t rex can also fight well against single raptor, unless there's a pair or pack.

I thought this was a path of titans video because of the yancungsaurus

8:32 How this small herbivore stand against adult t rex which is something bigger?

[giri_]

7:56 What this thing do to adult rexes, even for sub-adults? These herbivores have chance slightly above inexperienced juvenile.

[giri_]

11:01 Pack hunting is still not plausible in raptors, still they lack social intelligence though more intelligence animals.

[giri_]

2:26 Naah, though Armor is incredibly strong, T rex can bite through it. But not so easily, but surely if rex got it's enough time.
