Document Summary
Dinosaurs evolved greatly over the time period that they were alive 160 my means that their species were successful. Due to the changing earth, dinosaurs were forced to change as well. Canada = the best sites for dinosaur bones/fossils e. g. alberta badlands (can actually walk over bones here) There are specific structures in the badlands that help protect the dinosaur evidence and geological landscapes (see slides 3-5) Analyzing fossils for organic matter find pollen which can lead to what kind of plants existed at the periods of time reconstruct vegetation. There were many large earth changes during the dinosaur era which may have contributed to many factors of their lives (e. g. migration and variation) Dinosaurs lived from the end of the triassic through the jurassic and into the cretaceous (extinction occurred at end of the cretaceous period) Giant continent some island but the land masses are generally connected to one another.
