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!
