About this guide
The article “What makes a dinosaur?” describes how new fossil evidence could make defining a dinosaur and describing the dinosaur family tree more difficult than was previously believed. Students can focus on information and graphs reported in the article, follow connections to earlier articles about dinosaurs and pursue cross-curricular connections in earth and biological sciences and engineering. In a related activity, students can study and identify characteristics on a number of real fossils.
