Explanation: 

Detailed explanation-1: -Fossils provide solid evidence that organisms from the past are not the same as those found today; fossils show a progression of evolution. Fossils, along with the comparative anatomy of present-day organisms, constitute the morphological, or anatomical, record.

Detailed explanation-2: -Fossils provide important evidence for evolution and the adaptation of plants and animals to their environments. Fossil evidence provides a record of how creatures evolved and how this process can be represented by a ‘tree of life’, showing that all species are related to each other.

Detailed explanation-3: -Today’s fossil record is even more convincing. Often, fossil species first appear in older rocks and disappear in younger rocks, providing evidence that species change. Changes in climate, indicated by geology, correlate with changes in fossil species and their adaptations, supporting the idea of natural selection.

Detailed explanation-4: -The primary site of these fossils is Dinosaur Provincial Park, Alberta. Well-known dinosaurs first named from Canadian specimens include Albertosaurus, Centrosaurus, Corythosaurus, Dromaeosaurus, Gorgosaurus, Lambeosaurus, Pachyrhinosaurus, Parasaurolophu sand Styracosaurus.
