Active Debate: Ornithischian Evolution and Cretaceous Asian Ecosystems
Whether ornithischians like Shuangmiaosaurus were part of endemic Asian faunas or connected to broader Asian dinosaur communities is debated. The evolution of ornithischians in the Cretaceous of Asia — and their ecological roles — is key to understanding Asian dinosaur ecosystems.
What We Still Do Not Know About Shuangmiaosaurus
