What does the T Rex's Humerus Bone Looks Like?
Tyrannosaurus rex was about 40 feet long and about half that tall. They had three toes on each of their two feet, and their arms were extremely tiny in proportion to its body size (in fact, they were completely useless because they were so short). T-rex was supported by a heavy tail that helped to counterbalance its head and upper body, giving the T-rex's body a horizontal posture. Of course, T-rex also had a large head, and its powerful jaws were lined with banana-shaped serrated teeth, some of which were sharp for tearing and others which were blunt for crushing bones.

What caused the t-rex to go extinct?
A meteorite impact that caused plants to cease production of pollen, meaning that flowering plants had shut down, causing a chain reaction up the food chain that eventually led to the extinction of the T-Rex.
Tyrannosaurus rex was clearly a large carnivore, and therefor ate other dinosaurs. However, Jack Horner believes that T-rex were not hunters, and that they instead scavenged for food. Some of his evidence includes that T-rex had an incredibly large part of the brain designated to its sense of smell, and therefor could detect carrion from miles away. They also had bone crunching teeth, which are characteristic of some scavengers. Also, a Triceratops pelvis bone was found with tooth marks from T-rex on it. Because that is a hard part to get to, the T-rex was probably just trying to get
any last piece of meat off the bones because the carcass had already been mostly consumed. That seems unlikely if the T-rex had killed it, because it would have had plenty to it without those last scraps.
However, fossils of Edmontosaurus show tail bones that were damaged by T-rex teeth, but had time to heal before the Edmontosaurus died. If T-rex only scavenged, the Edmontonsaurus wouldn't have been bitten until after it died, and therefor couldn't have healed.
To me, it seems clear that T-rex was like many modern predators (IE, lions, hyenas, etc). It hunted, but it also took the opportunity for a 'free meal' whenever it could.
How much does a baby t-rex weight?
Dosing a baby Tyrannosaurus Rex.
Firstly you would need to find a baby T-rex. Quite difficult.
As there are no experts in veterinary diseases for extinct animals you would also have a problem finding finding one to cater there.
In addition you do not state what illness the baby T-rex has so that also creates a problem.
A spoonful, maybe.
What period is the T Rex from?
Tyrannosaurus rex lived between 68 and 65.5 million years ago. That was at the end of the Maastrichtian stage, the last stage of the Cretaceous time period. They became extinct 65.5 million years ago, during the K-T mass extinction event.
Is the blue whale bigger then a t-rex?
The ultrasaurus is the only one larger than the blue whale, measuring at 572 ft. long and 509 ft. tall. Believe it or not, it's true. And no, it's not a popular dino. This dinosaur had a NECK longer than the whale, surprisingly at 299 ft. This was a long necked herbivore, and it walked on all-fours. A scientist named Coalinsa Magyreds Gimadersfret (Russian) discovered this and a creature named Ocroplosaurus. It took 4 cranes to lift Ultrasaurus off the ground, considering it weighs about 23,001 tons (46,002,000 pounds!!!!!)!!!!! There is 2 complete skeletons. 9 are incomplete.
Who is stronger spinasour or t-rex?
Spinosaurus/spinosaurus egypticus would have been bigger and more aggresive but if you are thinking of the fight between the T.rex and Spino, the T.rex would win due to the Spinosaurus hands not being able to break its neck.
What is the closest relative alive of the T rex?
i think it would be... an ostrich, a crocodilia, a bird, or an alligator :3
What are the Physical Characteristics of a T Rex dinosaur?
It's believed they are big in all area's except the arms and "hands".
How do you pronounce tyrannosaurus?
The correct spelling is tyrannosaurus (a carnivorous bipedal dinosaur). This may be capitalized as it refers to a genus Tyrannosaurus, which includes the species Tyrannosaurus rex.
Where can you find pictures of T-Rex on the web?
There are many resources one has when seeking dinosaur pictures. Activity Village, Educational Coloring Pages, and Kids Dinosaurs each have many pictures on their website which one can print for children.
Who is stronger T Rex or Carcharadontosaurus?
A T-Rex of coures, because a T-Rex is bigger than a Allosaurus alot, and have a more powerful bite
Which meat eaters are bigger than Tyrannosaurus Rex?
1. Giganotosaurus
2. Spinosaurus
3. Carcharodontosaurus
4. Mapusaurus
Epanterias and Saurophaganax may be bigger than T-Rex and a new mystery carnivore has been discovered in Argentina that may be bigger than both T-Rex and Giganotosaurus.
What is bigger a blue whale or T-rex?
What do you think? A long 100 ft Blue whale or a 45ft long T-Rex? So yeah a Blue Whale
How did a T-rex catch its prey?
No one really knows for sure but personally I subscribed to the ambush theory.
However I don't think it took place in the way that we see in so many tv reconstructions - which always full victim at some point to depicting the t- rex as an Olympic sprinter - jumping from behind a bush and running the last 100ft to devour everything in sight. T - rex just couldn't do that. It wasn't built to run at all, not even very short distances and the consequences for falling would've been catastrophic. So how did it catch its prey?
How I think it happened...
Instead of thinking of the t - rex as an ambush predator that has to run at some point, lets think of it more along the lines of a crocodile. Not that it lived in water but that it treated or used the edge of a 'tree line' very much like a crocodile uses the edge of a water line.
Picture an animal that patiently waits hour after hour, standing completely still amongst the trees, almost completely hidden, perhaps 2 or 3 metres from the edge of a clearing. Some sort of prey animal comes along at some point, feeding on the edge of the tree line, maybe stretching its neck like a modern day Giraffe to reach the leaves. Again, just as with a Crocodile the t - rex will not launch until just the right distance is established. Nearer and nearer and then suddenly, within a certain distance... the trigger is switched.
Two steps forward, it grabs the neck with unbelievable force. Releases and then retreats back into the tree line to avoid injury from the hysterical flailing victim. T- rex is exposed with virtually no protection around the mid drift. Just as with any modern day predator it would've instinctively recognised the danger of being injured by its prey. All it has to do (if it's delivered a good enough bite) is patiently wait until its victim bleeds to death. The bite may well have been like that of the Komodo Dragon, by which I mean very dirty and highly infectious. Once the danger is past and retaliation impossible, it can comfortably close down the carcass.
If that's right, then this could be why t- rex has such small arms. It clearly doesn't use them and really the larger they are - the greater the hindrance for trying to move quickly through thick plant material. Small arms make sense for the hunting theory I described. Meanwhile it still has powerful legs and forward facing eyes to get the job done.
When did the tyrannosaurus rex live?
The Tyrannosaurus rex lived about 66 - 65.5 million years ago in North America. That time was the Maastrichtian stage of the Cretaceous period, the very last part of the Mesozoic Era. T-rex was one of the dinosaurs that died out during the K-T extinction. The Tyrannosaurs where indeed covered in plumage, but most likely its feathers where brown or black.
How strong is the bite force of the tyrannosaurus rex?
According to paleobiologist Dr Gregory Erickson (from Florida State University), the Tyrannosaurus Rex had a bite force of 18000 pounds or more! This is equal to 8164.66 kg. Dr Erickson states that this bite force is more than enough to bite through a car door. Also, the word "tyrannosaur" refers to a group of predatory dinosaurs that lived from the late Jurassic period to the latest cretaceous period, at which time they reached their greatest dominance. Tyrannosaurus Rex, or (T.Rex), is just the best known member of this group.
How many bones does a t-rex have?
No full T-Rex skeletons have been found but around 200 bones is a good estimate.
Where was tyrannosaurus found?
Sue was found in an archaeological dig site. The archaeologists found almost all of her skeleton, with only a few bones missing. However, without her tendons and ligaments, her head was too heavy to be put on the actual skeleton itself so it is in a glass display box at the Chicago Field Museum. The skull on the assembled skeleton is fake, along with the other missing bones.
How did tyannosaurus rex compare in size to utahraptor?
Tyrannosaurus Rex was an average of 20 ft. tall and 40 ft. long, Utahraptor was an average of 10 ft. tall and 20 ft. long-Making T-Rex approximately 2x the size of Utahraptor in both mentioned dimensions. Of course outliers exist( A situation in which Much larger-and much smaller specimen occur as compared to the mean value in any given dimension of a species.), However these are the "average" values.
When did the Tyrannosaurus Rex die?
About 65 millon years ago. It was one of the last dinosaurs to live.
Most dinosaurs, including tyranosaurus rex, died off about 65 million years ago.
Most life on Earth ended 65-66 million years ago during what is called the Cretaceous–Paleogene extinction event.
There is substantial scientific evidence of an asteroid impact on Earth that caused or was a significant contributor to the extinction.
Some dinosaurs (the theropods) probably are still around - we call them birds
If a t-rex was alive can it eat humans?
I have seen fossil T-Rex skulls, and the opening at the back is big enough for an average sized human to fit through. So yes, a T-Rex most likely could swallow a human quite easily. They do have a mouthful of sharp teeth, though, so said human might be dead by the time they went down.
How could scientist know that t Rex ate meat?
Scientists are able to tell the foods that dinosaurs ate because of many different circumstances. One of these is the fossilization of the stomach contents of the dinosaur. For example, if an Allosaurus were to be fossilized after it had consumed a meal, then some of the stomach contents would also be fossilized, though in the case of dinosaurs it would have much less of these preserved stomach contents.
Another way that scientists were able to tell the stomach contents was actually examining the fossils of the dinosaur's prey. Often times, the dinosaur would have left bite marks where the teeth slashed into the bone, making large gashes in the bone that would be preserved in fossilization.
However, the two methods described above are actually only valid for carnivorous dinosaurs. Herbivores would actually have their teeth examined, which would show both the wear on the teeth, and also quite obviously the shape of the teeth, which would be adapted to chew up its food. From there, Scientists are able to make an educated guess, where they would see what kinds of modern plants descended from prehistoric plants had which kinds of traits. From there they would examine the teeth, finding which plant the tooth would appear to be well-adapted to eating, then tracing the plant back to its dinosaur-age ancestor, and thus finding out the food of the dinosaur.
True enough. Another, somewhat more uncertain way, is to note the coprolites (fossilized dung) and break it up for analysis. Chemical analysis is useless of course because such fossils are no longer organic in nature, but one can often see what was excreted and estimate what was ingested. And of course, there is the disadvantage of not being sure what animal deposited the fossil. However, if one finds piles of coprolites amidst large numbers of bones of a single dinosaurian species, it's a pretty fair guess that the dung was deposited by them

Who will win a Baryonyx vs a T-Rex?
T-rex wins hands down. Baryonyx was about 30 feet long whereas T-rex was about 45 feet long. T-rex had a biteforce of around 6,000 to 10,000 psi. Baryonyx had a biteforce of less than 1,000 psi. T-rexes were fast, aggressive, and durable. Baryonyx was fast and agressive, but not durable. T-rex would easily crush a Baryonyx's neck with one bite.
