Ceratopsids

Ceratopsids were a group of animals that had a frill at the back of the head, some of them had horns, But all had a beak. Read more to find some cool facts about these types of animals

The most famous one was Triceratops. It had all of these features, a large frill, huge horns, and a beak. This animal had huge horns that were 3.3 f.t. (1m) in length. The frill was solid bone, really thick! It's beak was so powerful that it could snap a person's arm (even though they wouldn't!). Triceratops was a pretty big animal. It was 30f.t. (9m) in length. It lived in the Late Cretaceous. It was found in western North America. This one is my favorite dinosaur!

Styracosaurus was smaller then Triceratops but the most distinctive parts of Styracosaurus was its frill had huge horns on it and one large horn near the beak was 2 f.t. (60 cm) in length. it could use this horn when a predator came to attack the Styracosaurus would go beneath the stomach then with its huge horn slice it the attackers belly open. It was 18 f.t. (5.5m) in length. it lived in the Late Cretaceous. it was found in North America (in Alberta, Canada too). Its name means " spiked lizard" and that is quiet true!

Prodoceratops was one dinosaur that only a bump near its snout. No big horns at all! It had a beak and a frill, but still no horns! even though it had no horns when it had baby's to protect it was aggressive. It would charge at its enemies it could either bush and jab at its attacker or it could bite the attacker on the arm or slice the belly open with its beak. it was small compared to its way bigger couins. It was found in Asia, Mongolia. It was 9 f.t. (2.7 m) in length. it lived in the Late Cretaceous. He maybe small, but he is aggressive!
There are lots more ceratopsids in the Cretaceous world and they are all pretty cool too!

Utah and Montana's Dinosaur History

Dinosaurs have been found all over the world ... even at the cold poles! There are all types of dinosaurs, from carnotors to cerosapiens, sauropods e.t.c.
2 states in the United States have a lot of species of dinosaurs. Montana has a lot of Late Cretaceous dinosaurs. Some dinosaurs were Edmonosaurus, Triceratops ( my favorite dinosaur ), Tentontosaurus, Deinonocus and the famous Tyrannosaurus- rex e.t.c.
In Utah ( where my cousins live ) some Late Jurassic dinosaurs were found. Some dinosaurus were Allosaurus, Stegosaurus, Camrosaurus e.t.c.
Some cool things were found in Utah. Like when paleontologist found 40 Allosaurus skeletons in 1 site. IN 1 SITE WITH 40 ALLOSAURUS SKELETONS !!! Or when scientist uncovered a site with dinosaur skeletons mixed-up all together 1 site. The dinosaurs Found were Braciosaurus, Allosaurus, Stegosaurus and Camrosaurus. My family was going to see it, but the exibit was being worked on!
Montana is cool too. Besides... it is home to Sue the the biggest and most complete Tyrannosaurus skeloton ever! Right now it is displad in Chicogo. It is also home to Triceratops, One of the most famous dinosaurs ever.This could have been home to some battles of T-rex v.s. Triceratops and Tentontosaurus v.s. Deinonous.
They're a lot more sites of cool dinosaur sites out there, but I know about Montana and Utah!

Parasaurolophus

Parasaurolophus is a duck-bild dinosaur. The reason that their in the duck-bild family is because they have a snout shaped like a duck. It also has a crest that makes a trumpet kind of noise. As they breathe the air gos up the crest and comes down(pus the crest is hollow) and the cavity makes the trumpeting noise. Scientist think that the males had the biggest crest, the females had smaller crest and the juveniles(baby's) had the smallest crest. Females take care of the juveniles while their still young. If a this dinosaur was alive today you could not see the teeth because they are in the inside the moth by the cheek. these teeth are used to grind up leafs and other vegetation. They DID NOT eat grass because it did no t evolve yet! Parasaurolophus had a ton of enemies. Like T-rex, Dromeosaurus, crocodiles and other predators. It was found in North America. Sense I have had a lot of blogs you can write your favorite dinosaur and if I DID NOT write it maybe I will!. Bye!

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.

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?
