恐龙的髋骨分类

根据髋骨结构将恐龙分为两大类：Saurischia（蜥臀类，包括兽脚类恐龙和蜥脚类恐龙）和Ornithischia（鸟臀类，包括三角龙和剑龙）。

Classify dinosaurs into the two major groups based on hip structure: Saurischia (lizard-hipped, including theropods and sauropods) and Ornithischia (bird-hipped, including Triceratops and Stegosaurus)

学习证据 / Evidence

• 说出恐龙的两大类：Saurischia（蜥臀类）和Ornithischia（鸟臀类）
• 解释这两类的区别是基于髋骨结构（蜥臀型与鸟臀型）
• 正确地将至少两种恐龙归入每一类（例如：T. rex属于Saurischia，Triceratops属于Ornithischia）

• Name the two major dinosaur groups: Saurischia and Ornithischia
• Explain the difference is based on hip bone structure (lizard-hipped vs bird-hipped)
• Correctly classify at least two dinosaurs into each group (e.g. T. rex = Saurischia, Triceratops = Ornithischia)
