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

Hi, thanks so much for sharing your great unit studies! I was wondering if there are more days in the dinosaur study. I see days 8-16. Thanks again! Caroline
