On this page of Ancient Beasts, we’ll discuss the various dinosaur orders, suborders, and infraorders in the taxonomy today. You’ll be able to see how the major groups are organized and related.
At the time of writing content for this page, there are only two significant dinosaur orders in the Dinosauria group. They are Saurischia and Ornithischia. The primary distinction between them is that Saurischia dinos have lizard hips, whereas Ornithischia has bird hips. An easy way to remember this is that Sauria means reptile and Ornis relates to birds.
While we refer to these as the main dinosaur groups, there are suborders, infraorders, and other groups under them before we get to families. Instead of having a page for each of these, we’ll cover all of them here in Ancient Beast’s Dinosaur Orders section.
The articles that appear in the panels below not only show how the dinosaur orders are related, but also which are the top families you’ll find in them. It’s also in this section that we’ll investigate the 7 major dinosaur groups that you should be aware of before progressing further in the taxonomy.
