Strongylocentrotus purpuratus, a well-armoured sea urchin. Armour is evident in numerous animal species from both current and prehistoric times. Dinosaurs such as Ankylosaurus, as well as other Thyreophora (armoured dinosaurs such as Ankylosauria and Stegosauria), grew thick plate-like armour on their bodies as well as offensive armour appendages such as the thagomizer or a tail club.
Many amphicyonid lineages instead adopted a digitigrade posture and locomotion (walking on their toes) and long legs specialized for running with a primarily front-to-back arc of movement. These cursorial wolf- or hyena-like forms included temnocyonines, [ 16 ] haplocyonines, [ 17 ] and some species of the large daphoenine Daphoenodon .

Superficially, acanthoracids resembled scaly chimaeras or small, scaly arthrodires with blunt rostrums. They were distinguished from chimaeras by a pair of large spines that emanate from their chests, the presence of large scales and plates, tooth-like beak plates, and the typical bone-enhanced placoderm eyeball.
