I love t-rex, prehistory was the domain of t-rex. The big reptile king of prehistory as a brown bear is king of our time.

TYRANNOSAURUS REX Your daily reminder that cloning dinosaurs would be a “very bad idea.” The serrated teeth of a #Trex aren’t just sharp, they’re BIG. In fact, the largest discovered tooth of any carnivorous dinosaur was a whopping 12 in. long and belonged to this “Tyrant Lizard.” However, most of their length was embedded in the jaw bone, so what you see on the outside is only about 1/3 of the tooth! #FossilFriday — at Cleveland Museum of Natural History.

/\ The T. rex’s tooth has a deep root which contributes to its bone crushing jaws.

According to: 'Other large predator videos' - Reply #209 - In comparison, the skull of Carcharodontosaurus saharicus was thin and lightweight. No land-based predator ever had the girth nor the bite-force to equal a T-rex.

A giant 3,000kg ( 6,000+ pounds ) crocodile could ( sometimes ) kill a T-rex from ambush at the edge of a river. But, in a face-off confrontation on dry land, the 'King of the Dinosaurs' would win probably 8 or 9 out of 10. Some of his dinosaur prey defend themselves by using their tails as weapons - example: Ankylosaurus. Being bipedal means that T-rex is much more maneuverable. We can also make the probable educated guess than the crocodile will become totally exhausted long before the Rex is too tired to fight.

Result of your conversion: 8828.9 kilograms is equal to 19,464.39 pounds (avoirdupois) - Tyrannosaurus rex.

Sarcosuchus was unable to make death rolls.

Quote: Deinosuchus at least. Sarcosuchus was unable to make death rolls. *I didn't know that about Sarcosuchus. But, in reality, the only giant crocodilian ( probably an alligatoroid ) living within the domain of the Rex was Deinosuchus.

Like the our age king, brown bear, the prehistoricking t-rex also had a slow gait.

As one who has done and does a lot of walking, I figured out long ago that my normal relaxed walking speed is 3mph. It takes me about 20 minutes to walk one mile; 40 minutes to walk two, 1 hour to walk three, and 3 hours to walk nine miles. Good to know that my walking speed is perfectly natural.

It looks like you read my mind, incredible. It takes me the exact same time. I usually walk 6 miles a day, 4/5 times a week. It takes me around 20 minutes per mile yes.

The Tarbosaurus can kill a man with one bite. Wouldn’t want to be close to that thing if it was alive.

www.sciencedaily.com/releases/2021/04/210420121419.htm Fearsome tyrannosaurs were social animals, study shows. The fearsome tyrannosaur dinosaurs may not have been solitary predators as popularly envisioned, but social carnivores with complex hunting strategies like wolves. The fearsome tyrannosaur dinosaurs that ruled the northern hemisphere during the Late Cretaceous period (66-100 million years ago) may not have been solitary predators as popularly envisioned, but social carnivores similar to wolves, according to a new study.

The tyranosaurus probably operated in a pack when hunting down dangerous prey. Its like with Smildon. The experts are divided on this issue. Some strongly believe that they were pack hunters. Others believe just as strongly that they were strictly loners. Most of the experts simply admit that there is not definitive proof either way. I agree that the answer remains unsolved. But, I would prefer the loner scenario. Why would T-rex hunt in packs? Its not like he cannot catch and kill the big dick-billed dinosaurs or the slow-moving armored variety. As a loner, once killed, all the meat is his. This is the second site discovered containing multiple tyrannosaurs of every age group. But, most discoveries are of one lone T-rex. A mystery. I'm wondering if ( like the sperm whale, perhaps the females and young herded, while the males only showed-up at breeding time? But, this would be near impossible to prove; and merely a thought.

www.sciencedaily.com/releases/2021/04/210422102836.htm Fat-footed tyrannosaur parents could not keep up with their skinnier adolescent offspring. New research suggests juvenile tyrannosaurs were slenderer and relatively faster for their body size compared to their multi-ton parents. New research by the University of New England's Palaeoscience Research Centre suggests juvenile tyrannosaurs were slenderer and relatively faster for their body size compared to their multi-tonne parents.

Juvenile Tyranosaurus probably hunted much more agile prey than their adult parents too. Some male leopards gain a bit of bulk when they get older (pass 5 years old) and target the slower and more dangerous warthog instead of the faster impalas.
