Rubeosaurus was a ceratopsian. It is thought to be an adult specimin of Brachyceratops, a smaller ceratospian. There have been very few remains found from this dinosaur. Here are a couple pictures.

                                 Prosaurolophus was a Ornithopod. It grew to be about 28 feet long. I couldn’t find any estimate about the weight of this dinosaur. Prosaurolophus was discovered at Dinosaur Park Formation, and would have lived in floodlands and swamps. It’s skull was about 2.9 feet long.

                       Pentaceratops was a ceratopsian. It’s name meant “five horned lizard,” meaning the nose horn, to forehead horns, and a small, almost undistinguishable horn that juts out sideways from under each eye. It was about 27 feet long and weighed around 13,000 lb!!!! Pentaceratops is known to have the largest skull of all dinosaurs, because the frill just upwards, going quite high, and looking very scary. Here are some pictures. If you are finding mistakes in my posts, please ignore them, because my computer monitor is not working, and the screen on which I write my posts, is a dark, dark, dark, dark, blue. So please excuse mistakes. I can’t even see what I am writing, I can just see vauge dark spots everywhere.

Parasaurolophus was a duck-billed dinosaur. It was a herbivore. Parasaurolophus is a very well-known dinosaur. When duck-billed dinosaurs are mentioned, this is one of the first ones that people think of. Parasaurolophus grew to be 30-40 feet long, depending on the species. It grew to be 2.5 tons-3 tons. This thing was a beast!!! Like other hadrosaurs and duck-billed dinosaurs, it stayed on all fours to forage for food, and ran on its hind legs. Parasaurolophus is very well-known for its large head crest, which looks like a large hollow tube that comes out of its head and, going almost straight backwards, curves like a scimitar. Here are some pictures.

Pachyrinosaurus was a Ceratopsian.  Pachyrinosaurus had a small nose horn  stub and a couple of shorter horns that protruded from its frill. Pachyrinosaurus adults could grow to be 26 feet long, and weigh 4 tons. That is a pretty good size for a dinosaur.    Three different species have been identified from the Bearpaw, Horseshoe, and Prince Creek Formations. Here are a couple of pictures.

Who loves Pachycephalosaurus?!! I DO!!! Pachycephalosaurus was a herbivore. It was a hard-headed dinosaur. It had spikes on its head. They could have been used to have a head-butting competition, or it might have been used to scare, and if they didn’t back off, to charge predators. Sorry for not having written for a while. I have been pretty busy, with summer vacation, family get-togethers, campouts, and that kind of stuff. Now I am going to write a blog post two days a week, on Monday and Friday.  Here are a couple of pictures of  Pachycephalosaurus.


Location North America.svg                                     Othnielia                                           

                           Othnielia was a herbivore.  It was an Ornithopod, which were close relatives of hadrosaurs. Many skeletons are known from Othnielia. These small dinosaurs weighed only about 22 lb and were anywhere from 4-6 feet long at maturity. These small dinosaurs may have been able to climb trees, as they are shown to do in the famous movie, Jurassic Park.File:Fighting Othnielia.jpgFile:Othnielia.png


Location North America.svg                               Oryctodromeus                            

                       Oryctodromeus was a member of the family  Hypsilophodontidae. Oryctodromeus is known from an almost complete skeleton, and also two partial juvenile skeletons, the first one having 50 percent of all of the bones in Oryctodromeus, and the other, 65 percent. We are still not sure if Oryctodromeus is a omnivore, like some of his relatives, or if he is a herbivore.   Oryctodromeus is one of the only dinosaurs that is thought to have burrowed. It was very fast and agile. The three skeletons that have been found were found in a burrow-like hole, like the kind that Hyaenas and Puffins make, being filled with sand. Paleontologists believe that the skeletons mentioned above died and decayed in the burrow.

                        Mymoorapelta was an ankylosaur. It was one of the ‘earlier’ ankylosaurs. It is a close relative of Gargoyleosaurus.  Mymoorapelta had large spikes sticking out of its sides, which would have helped it to be safer from predators. It also had spikes along its tail, which it may have been able to swing like an Indian Tomahawk. It would have been able to cut right into the legs of huge predators like Tyrannosaurus, and Spinosaurus, or have knocked the heads off of smaller raptors like Deinonychus, Velociraptor, and Utahraptor. Here are some images of Mymorrapelta.

Location North America.svg                     Montanaceratops         

                         Montanaceratops was a ceratopsian. It was a herbivore. It is one of the only ceratopsians who has no nose horn. It has cheek horns, though, and is closely related to Leptoceratops. It was originally though to be Leptoceratops, until more evidence was found, showing that they were different species. Here are some pictures. Montanaceratops life-like, here is a picture of an out-dateskeleton of Montanaceratops with a nose horn. Montanaceratops skeleton. Here is one more, showing a big slab of rock, filled with Montanceratops  bones. Montanaceratops . That is all for today.
