Discovering Dinosaurs: The Secrets of Fossils

In "Dinosaur Fossils," Dr. Alvin Granowsky unveils how scientists learn about ancient plants and animals through fossils. These remnants, left behind by creatures long ago, offer a glimpse into the past. The process of unearthing and reconstructing these fossils can be challenging, especially when pieces are missing. This expository text provides clear, factual information about how paleontologists study fossils to understand the history of life on Earth and the concept of extinction.
