Evolution of The Dinosaurs

Lecture by Nicole Ridgewell

Location: meet up in tearoom, move to Ryerson


What is a dinosaur?  The purpose of this lecture is to answer that question.  I will give a basic introduction to phylogenetics and show how biologists use cladistics to understand the evolution of life.  I will give a summary of tetrapod evolution to show where dinosaurs fit on the tree of life.  I will show how biologists define groups of organisms, specifically dinosaurs.  I will explain the distinguishing features of the different major groups of dinosaurs and show how the groups are related to one another.
