T-rex

T-rex is a favorite around the world. Trex is the 2nd biggest meat-eating dinosaur. It was 40 feet (12 m) long and estimated to weigh 5-6 tons. T-rex is so popular it was in my favorite movies Jurassic Park. Its nick name is tyrant king lizard and I can see why! hard to believe that its teeth can be as longs bananas! Scientist are not sure what T-rex's arms were used for but I read in some books that it may have helped it while lying on the ground push its self off the ground. T-rex could not have run super fast because of its weight, but it may have ran about 20-25 mils per hour. T-rex was an ambusher. It would hide and wait for a little then at the right moment and when it selected its prey it would charge at surprised prey. Then the chase was on! It would clamp down on its victim with banana sized teeth and hold it until the prey was tired out and died. Then it would eat. It did prey on duck-biled dinosaurs like Maiasaura and ceratosians like triceratops(let triceratops win). T-rex lived in the late Certaceous. T-rex had a long tail to balance its body weight. Sue the T-rex is the most complete skeleton of any T-rex.I read about Sue but I can't remember it but I do Know that it was found by a paleontologist named Sue and her pet dog. T-rex is one interesting animal!

Diplodocus

Diplodocus was a sauropod of the late Jurassic. It was 90 ft. (27 m) long. It's tail is like a whip that will lash out on an attacker and boy that would hurt! Because of it's whip tail it is considered a whip tailed sauropod. It was found in Utah,Colorado and Wyoming. Diplodocus has peg teeth for striping off plants. It didn't have it's neck held high so it held it level. Diplodocus had front legs shorter than it's back legs. It could rear up on it's hind legs and get hard to reach leaves, but not hold it for a long period of time.

Baryonyx

Baryonyx is the rarest dinosaur. Only one skeleton has been found... ONE SKELETON!!! Baryonyx has a suckle shape claw that helps to catch slippery fish.That claw can be 30cm long. It's length is 30 ft. (9.1 m). It lived in the Early Cretaceous 121 millon years ago. It was found in Southern London. Baryonyx is a spinosaurids like spinosaurusand others.It had a crocodile mouth.

Biggest Meat-Eating Dinosaur v.s. Largest Dinosaur ever

Giganotosaurus is the biggest meat-eating dinosaur ever! It was found in South America, Argentina. It lived in the Late Certaceous. It was Bigger than T-Rex and Carcharodontosaurus! It was 42 feet ( 12.5 m). It hunted in packs because it attacked sauropads like Argentinosaurus. It's skull was long as a human! It was one big dino!
Now if you thought that Giganotosaurus was big ... THINK AGAIN! Argentinosaurus was the biggest dinosaur ever! It was 123 feet (37.5m). It is a sauropod ( it is in the picture). Early Cretaceous. Each back bone weighs 2 tons. it was a plant -eater. It was named after Argentina.
Now imagine the 2 dinosaurs we were talking about fighting. Wouldn't that be cool! Giganotosaurus slicing teeht. Argentinosaurus had size. 2 BIG dinosaurs fight. one big questin remains .. who would win!? Who knows? Maybe Giganotosaurus, or Argantinosaurus. Who knows?

Mix Up Years for Iguonodon

When the dinosaur named Iguonodon was discovered scientist thought that Igonodon had a horn on it's nose like the middle nose horn of Triceratops. Then later in the years scientist relised that the horn was really a thom-spike. But one person made a park with Iguonodon and other dinosaurs ... in older fashion!
Iguonodon was the second dinosaur ever found, the first dinosaur was Megolosaurus. Iguonodon was a comen dinosaur because so many skeletons of Iguonodon. It was found in Europe and North Amarica. The reason it was named Iguonodon because ithd teeth of a iguana.

No More Brontosaurus

There was a mistake with Brontosaurus. There was a story that a scientist found bones of a huge long-necked dinosaur named Brontosaurus. Later the same scientist found the bones of another long-necked dinosaur named Apatosaurus. In 1903 another scientist named Elmer Riggs looked at both skeletons and he realised that Brontosaurus had the body of a Apatosaurus and the head of a Camarasaurus head. WHAT A MIX UP!
But another mistake with ALL dinosaurs...there tails were dragging! All scientist say that dinosaurs tails were held up because when dinosaurs walked near a base of water the sand and mud mix together they make fossilised foot prints. If dinosaurs did drag their tails they would have been fossilised.
