Dinosaurs Day 8: Mesozoic Era

Mesozoic Era

Read: read/do pages page 4-5 in Dinosaurs:Diggin' Discovery (A+ Let's Grow Smart!).

Discuss: "THE AGE OF REPTILES"

• The climate of the Mesozoic Era was generally warmer and more tropical than

what we experience on Earth today.

• The seasons were very mild.

• There was no polar ice.

• Sea level was higher.

• Greenhouse conditions existed and there could have been higher concentrations of

carbon dioxide in the atmosphere.

• Polar regions had seasonal climates with windswept forests during the winter and

cool damp rainforests during the summer.

There are three periods in the Mesozoic Era:

• Triassic -Plateosaurus
• Jurassic -Brachiosaurus
• Cretaceous -Lambeosaurus

Dinosaur Flashcard: Separate the Dinosaur Flashcards into Triassic, Jurassic, and Cretaceous periods.

Dinosaur Journal:

Draw pictures and write about a dinosaur from each Mesozoic period.

Mesozoic Era Time Line

Directions:

Cut out the Mesozoic Era Time Line and place dinosaur flashcards under the time period that they belong.

DINOSAUR GRAPH

Graph the sizes of the dinosaurs. Then answer the questions at the bottom of the page.

In the graph, each box represents 10 feet. For each dinosaur, color in the right number of boxes to show how long it is.
