Jurassic Carnivore Dinosaurs
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.

Allosaurus Information
Translation: Different Lizard

Diet: carnivore

Period: Jurassic period

Family: Allosauridae

Height: 17 ft
Length: 38 ft
Weight: 4,000 lbs

Physical Appearance: This bipedal predator was up to 38 feet long and weighed roughly 1 to 5 tons. It had solid, heavy bones, long claws on its 3-fingered hands, and large, powerful jaws. Allosaurus has small ridges over its eyes

Lifestyle: Allosaurus was a carnivore (meat-eater) who may have hunted in packs. In these groups, Allosaurus could have ambushed even the very large sauropods.

Discovered by: Allosaurus was named in 1877 by paleontologist Othniel C. Marsh, based on fragmentary remains. The first virtually complete Allosaurus skeleton was discovered by rancher M. P. Felch in 1883, in Colorado, USA. (Find Colorado, USA on the world map).

Directions:  J filled in the Allosaurus Information Page to review what he learned.
Allosaurus Model

I found this Allosaurus Dinosaur 3D Model Discovery Kids toy at a garage sale.  It shows one side with skin on the dinosaur and the other side the skin is clear so you can see the internal organs of the dinosaur.

Archaeopteryx Information
Translation: Ancient Wing

Diet: Carnivore

Period: Jurassic period

Family: Archeopterygidae

Height: 1 foot
Length: 3 feet
Weight: 2 lbs

Physical Appearance: Archaeopteryx had sharp teeth, a long bony tail, and claw fingers on its wings.

Lifestyle: Paleontologist are not sure if Archaeopteryx could fly like modern birds or not.

Discovered by: Its remains were found in fine grained stone which still bore the clear impression of its feathers.

Directions: Fill out the Dinosaur Research Report with the information you learned about the Archaeopteryx.

Ceratosaurus Information
Translation: horn lizard

Diet: Carnivore

Period: Jurassic period

Family: Ceratosauridae

Height: 13 feet
Length: 20 feet
Weight: 2,000 lbs.

Physical Appearance: Ceratosaurus was a common meat-eating dinosaur with a short horn on its snout. This bipedal dinosaur had solid, heavy bones, primitive hands, and powerful jaws.

Lifestyle: This theropod dinosaur may have hunted in groups, preying upon large sauropod dinosaurs.

Discovered by: Ceratosaurus was named in 1884 by paleontologist Othniel C. Marsh. Fossils have been found in Colorado and Utah, USA, and in Tanzania, Africa.

Write a descriptive essay about being a Ceratosaurus 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?

Compsognathus Information
Translation: Pretty Jaw

Diet: Carnivore

Period: Jurassic period

Family: Compsognathidae

Height: 10 inches
Length: 3 feet
Weight: 6.5 lbs.

Physical Appearance: Compsognathus was a bird-like dinosaur that walked on two long, thin legs; it had three-toed feet. A long tail acted as a counterbalance and for stability during fast turns. It had short arms with two clawed fingers on each hand. Compsognathus had a small, pointed head with small, sharp teeth, hollow bones, and a long, flexible neck.

Lifestyle: Compsognathus is the smallest known dinosaurs, about the size of a chicken. Although he was small he was still very fast. Compsognathus had a good side brain for the size of his body, so he is considered relatively intelligent compared to other dinosaurs. Compsognathus had hallow bones like birds, that is why some believe that he had feathers and could fly.

Discovered by: Compsognathus was first discovered by Dr. Oberndorfer in limestone deposits in the Riedenburg-Kelheim region of Bavaria, southern Germany (Europe) in the late 1850's. It was named by Johann A. Wagner in 1859. (Find Germany on the world map).

Directions: I printed out the following questions for J to answer as a comprehension drill.

Discovered by: Megalosaurus was the first dinosaur fossil discovered (in England in 1676). It was also the first dinosaur given a scientific name - by William Buckland in 1824. Megalosaurus trackways have also been found in limestone in southern England. (Find England on the world map).

Directions: I printed out this Megalosaurus Dot-to-dot page for J to color.
J wrote a make believe story about Megalosaurus coming back to life in the museum.
