Suborder Thyreophora, a clade of dinosaurs that includes armoured dinosaurs like Ankylosaurids and Stegosaurids, has a range of synonyms coined over the years by different scientists. One such synonym is "Thyreophorans," which is frequently used by palaeontologists as an all-encompassing term for these armoured dinosaurs that evolved during the Jurassic and Cretaceous periods. Another term, "Stegosauria," refers to a distinct lineage of Thyreophorans that existed during the Late Jurassic and consisted of herbivorous dinosaurs that had a double row of sharp-edged plates that ran down their spine. Similarly, "Ankylosauria" refers to a distinct lineage of Thyreophorans that had a tough, bony armour covering their body. Together, these synonyms offer rich insights into the diversity and evolution of the Suborder Thyreophora.
