"Dinos A to Z: Spinosaurus" introduces one of the most unusual dinosaurs in prehistoric life and paleontology. The video explains how Spinosaurus got its name, meaning “spine lizard,” and explores fossil evidence showing it lived in Africa about 99 million years ago. Key science concepts include carnivorous dinosaurs, fossils, scientific hypotheses, adaptation, and semi-aquatic behavior. Viewers learn about its paddle-shaped tail, crocodile-like snout, diet of fish and smaller dinosaurs, and the large sail-like spine on its back. The video also highlights how new discoveries can change scientific understanding, making it relevant to life science and earth science curricula focused on dinosaurs, habitats, evidence, and the process scientists use to study extinct animals.
