Cretaceous Carnivore Dinosaurs

For today we learned more about 10 carnivore dinosaurs from the Cretaceous Period.

Discuss:

As you learn each dinosaur on this day look up the Dino Dictionary to see you to correctly pronounce their names, and find each dinosaur on the dinosaur classification chart that we made earlier.

Albertosaurus Information

Translation: Alberta Lizard

Diet: Carnivore

Period: Late Cretaceous

Family: Tyrannosauridae

Height: 15 feet

Length: 30 feet

Weight: 6,000 lbs

Physical Appearance: It had a huge head with long, sharp, saw-toothed teeth and two-fingered hands on arms that were longer than Tyrannosaurus’s stubby forelimbs.

Lifestyle: With its sleek build and long hind limbs, it was one of the fastest runners among the tyrannosaurids.

Discovered by: First discovered in Alberta, Canada, Albertosaurus stalked its prey almost 8 million years before Tyrannosaurus, a close relative. A jaw and teeth belonging to an Albertosaurus were identified by Joseph Leidy, who named the first American dinosaurs.

Directions:

Write a Descriptive Essay about being a Albertosaurus living in a particular region. What would the eat dinosaur eat; would it be a meat eater or a plant eater? How big would it be? What would it look like? What kind of plants and other animals/dinosaurs would be there? What would the weather be like? Would it be warm, hot or cool? Would the climate be wet or dry? What other details would you like to add?IMG_4206

Dromaeosaurus Information

Translation: Swift Lizard

Diet: Carnivore

Period: Cretaceous period

Family: Dromaeosauridae

Height: 2.5 feet

Length: 6 feet

Weight: 100 pounds

Physical Appearance:It had razor-sharp teeth and 3 inch eagle-like claws on the inner toe of each foot.

Lifestyle: Intelligent and aggressive, they would chase after their prey before jumping onto them to kill by biting and stabbing. They could live in groups, but preferred to hunt alone; they were capable of killing from a young age.

Discovered by: The first known Dromaeosaurus remains were discovered by paleontologist Barnum Brown during a 1914 expedition to Red Deer River.

Dromaeosaurus Measurement 

Materials:

  • Tape measure
  • Information about each dinosaur you want to measure

Procedure:

  1. Have children measure out the length and height of the Dromaeosaurus.
  2. Discuss with the children how big the dinosaur truly was. IMG_4197

Elasmosaurus Information

Translation: Thin-plated lizard

Diet: Carnivore

Period: Cretaceous period

Family: Elasmosauridae

Length: 46 feet

Weight: 2 tons

Physical Appearance: Elasmosaurus was a long-necked marine reptile. Half of its length was its neck, which had as many as 75-76 vertebrae in it. Elasmosaurus had four long, paddle-like flippers, a tiny head, sharp teeth in strong jaws, and a pointed tail.

Lifestyle: Elasmosaurus lived in the open oceans and breathed air. Some Plesiosaurs have been found with small stones in their stomachs; these may have been used to help grind up their food, or as ballast, to help them dive.

Discovered by: Elasmosaurus was named by paleontologist E. D. Cope in 1868 from a fossil was found in Wyoming, USA. (Find Wyoming, USA on the world map).

Its fingers were long and grasping. Oviraptor’s strangely-shaped, parrot-like head had a short, toothless beak and extremely powerful jaws, built for crushing action. It had a small, stumpy, horn-like crest on its head.

Lifestyle: It probably ate meat, eggs, seeds, insects, and plants with its beak and powerful jaws.

Directions:

Write a Descriptive Essay about being a Oviraptor living in a particular region. What would the eat dinosaur eat; would it be a meat eater or a plant eater? How big would it be? What would it look like? What kind of plants and other animals/dinosaurs would be there? What would the weather be like? Would it be warm, hot or cool? Would the climate be wet or dry?

Velociraptor Information

Translation: Speedy Thief

Diet: Carnivore

Period: Cretaceous

Family: Dromaeosauridae

Height: 2.5 feet

Length: 6 feet

Weight: 200 pounds

Physical Appearance: This meat-eater had about 80 very sharp, curved teeth in a long, flat snout; some of the teeth were over an inch long. This predator had an s-shaped neck, arms with three-fingered clawed hands, long thin legs, and four-toed clawed feet.

Lifestyle: Velociraptor was a fast-running, two-legged (bipedal) dinosaur. Velociraptor may have been able to run up to roughly 40 mph for short bursts. Velociraptor’s brain was relatively large in comparison to its body size.

Discovered by: Velociraptor was first found and described by paleontologist H. F. Osborn in Mongolia, Asia in 1924. In 1971, fossils of a Velociraptor and a Protoceratops were found together. They died together; the Velociraptor was attacking the Protoceratops with its claws and the armored head of the Protoceratops had apparently pierced the chest of the Velociraptor. (Find Asia on the globe).

  1. Undeniably imagine that that you said. Your favorite reason appeared to be at the net the easiest factor to keep in mind of. I say to you, I certainly get annoyed whilst other people think about worries that they just do not recognise about. You managed to hit the nail upon the highest and also outlined out the whole thing with no need side effect , other people could take a signal. Will probably be again to get more. Thanks
