National geographic - T Rex (Tyrannosaurus Rex) - New Documentary HD 2018
Tyrannosaurus[nb 1] is a genus of coelurosaurian theropod dinosaur. The species Tyrannosaurus rex (rex meaning "king" in Latin), is one of the most well-represented of the large theropods. Tyrannosaurus lived throughout what is now western North America, on what was then an island continent known as Laramidia. Tyrannosaurus had a much wider range than other tyrannosaurids. Fossils are found in a variety of rock formations dating to the Maastrichtian age of the upper Cretaceous Period, 68 to 66 million years ago.[2] It was the last known member of the tyrannosaurids,[3] and among the last non-avian dinosaurs to exist before the Cretaceous–Paleogene extinction.

Like other tyrannosaurids, Tyrannosaurus was a bipedal carnivore with a massive skull balanced by a long, heavy tail. Relative to its large and powerful hind limbs, Tyrannosaurus fore limbs were short but unusually powerful for their size and had two clawed digits. The most complete specimen measures up to 12.3 m (40 ft) in length,[4] up to 3.66 meters (12 ft) tall at the hips,[5] and according to most modern estimates 8.4 metric tons (9.3 short tons) to 14 metric tons (15.4 short tons) in weight.[4][6][7] Although other theropods rivaled or exceeded Tyrannosaurus rex in size, it is still among the largest known land predators and is estimated to have exerted the largest bite force among all terrestrial animals.[8][9] By far the largest carnivore in its environment, Tyrannosaurus rex was most likely an apex predator, preying upon hadrosaurs, armoured herbivores like ceratopsians and ankylosaurs, and possibly sauropods.[10] Some experts have suggested the dinosaur was primarily a scavenger. The question of whether Tyrannosaurus was an apex predator or a pure scavenger was among the longest ongoing debates in paleontology.[11] It is accepted now that Tyrannosaurus rex acted as a predator, and opportunistically scavenged as modern mammalian and avian predators do.

More than 50 specimens of Tyrannosaurus rex have been identified, some of which are nearly complete skeletons. Soft tissue and proteins have been reported in at least one of these specimens. The abundance of fossil material has allowed significant research into many aspects of its biology, including its life history and biomechanics. The feeding habits, physiology and potential speed of Tyrannosaurus rex are a few subjects of debate. Its taxonomy is also controversial, as some scientists consider Tarbosaurus bataar from Asia to be a second Tyrannosaurus species while others maintain Tarbosaurus is a separate genus. Several other genera of North American tyrannosaurids have also been synonymized with Tyrannosaurus.

As the archetypal theropod, Tyrannosaurus is one of the best-known dinosaurs since the 20th century, and has been featured in film, advertising, and postal stamps, as well as many other types of media.

When I was very young I would watch documentaries off dinosaurs etc for fun and now like 7 years later I’m still doing just that

Title: *T-rex documentary!*

The video: *you get mosasaurs*

[animaladventures]

Mosasaurs are cool in their own right. No need to decieve people by putting "T.rex" in the title of your video.

[taiipotatoie]

Imagine all the dinosaurs we haven't discovered because they're buried deep down in the sea 🤔

[cslame]

"mosasaur was the most ferocious animal to walk the earth"
Humans: "hold my beer"
🤣

[VERGILGASM]

I miss watching these dinosaur videos when I was a kid. Good times...

[Arnoldshah]

Everyone: meters, feet, inches, centimetres
American: as big as a greyhound bus, an Olympic pool, as heavy as a 🐎, as tiny as a boars hair.

[ImYourHucklebery]

Props for the diver camera 📷 man for surviving that long

[pinkpony]

Alright, Ima come clean…i just leave these documentaries on and fall asleep to them. Goodnight everyone :)

[Wallpaper_founder]

shoutout to the cameraman for being so brave to capture the clips of these beasts deep into the ocean. What a legend!

[MrCanDyMaNN]

Good grief that thumbnail picture is just a straight up brutal execution 😂

[keerthanr]

This documentary is really informative, I thank each and everyone who worked to create this documentary, but the title needs to be changed.

[datauser]

Good documentary, but you'd better change the title into "Mosasaur documentary".

[jayjayrocket]

Mosasaurus was the kid who got bullied at school and grew up to become a black belt in every martial art

[mitchellfanger]

I can't believe you bamboozled me! This is not a Trex documentray, this is a MOSASAUR documentary!

[Mussoi]

i came expecting a t. rex documentary but i was pleasantly surprised

[broderp]

Nailed the title of the video. Good job.

[paulstovall]

The mosasaur was the only animal to have 'terminator teeth'?
May I suggest you examine the moray eel?

[allygamess]

28:40 reminds me of those 6th grade girls that thought pulling each others hair was fighting

[Real_soul_records]

Not gonna lie this was the best thing on national geographic 😅💯❤️
