Plant-eating Dinosaur Fun Facts

This website is gonna tell you about a bunch of different dinosaur facts.

Ceratopsians

This is a picture of a bunch of different ceratopsians

They are the horned dinosaus.

Triceratops

try-serra-tops

When: 76-66 million years ago (late Cretaceous)

Triceratops had a big frill that was probably for display. But its horns were a weapon to get meat-eating dinosaurs away. It was as heavy as a 10-ton truck. Triceratops was built like a huge rhinoceros. It lived at the end of late Cretaceous. That’s it for triceratops.

Styracosaurus (my favorite)

sty-rack-oh-sore-us

When: 74-66 million years ago (late Cretaceous. A lot of ceratopsians lived at that time.)

Styracosaurus had one horn and a big frill. Styracosaurus had big, sharp spikes on the frill. It was about the same size as a human. That’s it for styracosaurus.

Protoceratops

pro-toe-serra-tops

When: 74-66 million years ago (late Cretaceous)

Protoceratops was the smallest ceratopsian ever discovered. Protoceratops had one tiny horn and a small frill. That’s it for protoceratops.

That’s not all the ceratopsians, but I think we can move on.

Iguanodontians

This is a picture of three iguanodontians

Most of them have sharp thumb spikes.

Iguanodon

ig-gwah-no-don

When: 135-125 million years ago (early Cretaceous)

It had a very big thumb spike that was probably used for defense. It was four-legged and it was a lot bigger than a human!! It could stand on two legs and four legs. That’s it for iguanodon.

I don’t know that much about any other iguanodontians.

Hadrosaurs

These are two hadrosaurs

Most of them had crests.

Parasaurolophus

pa-ra-sore-oh-loaf-us

When: 76-74 million years ago (late Cretaceous)

It had a big crest to make sound. It was probably the same size as iguanodon. It probably lived in groups.

Maiasaura

my-a-sore-a

When: 80-74 million years ago (late Cretaceous)

It was a very good mother, and father. It made nests and had a lot of eggs.

Corythosaurus

ko-rith-oh-sore-us

When: 76-75 million years ago (late Cretaceous)

It also had a large crest to make sound but it was in a different shape. Probably the same size as parasaurolophus. It walked on four legs.

Ankylosaurs

This is an ankylosaurs fighting a T. Rex

They are the armored ones.

Ankylosaurus

ank-ill-oh-sore-us

When: 70-66 million years ago (late Cretaceous)

It had a giant club tail and it used it to battle predators. It was the biggest ankylosaur. It had armor all over it. And its name means “armored head.”

Gargoyleosaurus

gar-goil-oh-sore-us

When: 155-145 million years ago (late Jurassic)

It was a very small dinosaur. Same size as a goat. It had armor all down it, but in the place where its back connected to its tail was a big plate of armor. It did not have a club tail.

Gastonia

gas-toe-nee-ah

When: 125 mill years ago (early Cretaceous)

When it swings its tail the spikes on its tail cross each other acting like a big weapon. It was probably the same size as a human. It was 13 feet long (4 meters). It had spikes all over it except on its belly. Its legs were like elephant legs! It’s a very cool dinosaur.

That’s it for the category.

Sauropods and Titanosaurs

This is a picture of some iguanodontians around some sauropods

They are the huge, long-necked ones. And the four-footed ones.

Brachiosaurus

brackee-oh-sore-us

When: 150-145 million years ago (ooooh, late Jurassic!)

Length: 75 ft (23 m)

Brachiosaurus is distinctive with a large crest from its eye to where its mouth starts. Like the others, it has a long neck, but it’s the only one that’s neck is slanted and then straight up.

Barapasaurus

buh-rah-pah-sore-us

When: 189-176 million years ago (early Jurassic)

Length: 59 ft (18 m)

It has the longest legs of any sauropod. It’s the only one that has a short tail. It has teeth that are all in a row, like all combined together into one grinder. Its neck is like a chain: long and sturdy. That’s it for this dinosaur.

Camarasaurus

kam-a-ra-sore-us

When: 150-140 million years ago (late Jurassic)

Length: 59 ft (18 m)

Why it’s named Camarasaurus is because it has a head shaped like a camera! Its number one weapon is that it lives in groups. It has teeth combined like a grinder, too. It’s kind of fast for its size.

Mamenchisaurus

ma-men-chee-sore-us

When: 155-145 million years ago (middle-late Jurassic)

Length: 85 ft (26m)

It had a neck longer than its whole body. It was way taller than Brachiosaurus! It had long, thin, roundish legs. If you saw it, it would be hard to make out its head because its head was the same size as its neck! That’s it for this dinosaur.

Vulcanodon

vul-kan-o-don

When: Early Jurassic

Length: 23 ft (7 m)

It was one of the smallest sauropods. It was also one of the shortest sauropods. You would think it had short and thin legs, but it actually had wide and kind of long legs.

Isanosaurus

ee-sahn-oh-sore-us

When: 216-199 million years ago (late Triassic, our first Triassic dinosaur!)

Length: 40 ft (12 m)

It was even shorter than vulcanodon. I would compare it to a rhino. They lived in groups. And their first defense method was groups, just like the camarasaurus. These dinosaurs had teeth more apart from each other than a human’s teeth! They had small eyes. And that’s why they lived in groups.

Diplodocus

dip-lod-oh-kus or di-plod-uh-kus

When: 150-145 million years ago (late Jurassic)

Length: 86 ft (26 m)

It’s the same size as memenchosaurus and it used its tail like a whip to fight danger! What makes it so big was that its tail was as long as camarasaurus!

Amargasaurus

ah-mar-gah-sore-us

When: 130 million years ago (early Cretaceous)

Length: 36 ft (11 m)

It had a giant sail running from the tip of its neck down to its tail. But now scientists think it was one sail divided into two sails. It might have walked in shallow water to get away from predators. It had a long tail.

Barosaurus

bah-roe-sore-us

When: 155-145 million years ago (late Jurassic)

Length: 92 ft (28 m)

They lived in herds. They had spikes down their neck to their tail. They probably lived in rainforests.

Up next, these are the titanosaurs.

Nemegtosaurus

nem-egg-toe-sore-us

When: 86-66 million years ago (late Cretaceous)

Length: 50 ft (15 m)

It had teeth together combined into one grinder, too. It had a very long neck. Its head could eat a branch.

Argentinosaurus

are-gen-teen-oh-sore-us

When: 112-95 million years ago (late Cretaceous)

Length: 100 ft (30 m)

It’s a titanosaur. It had teeth that could eat a branch, too. It’s giant. Its head was the same size as its neck, too.
