Panoplosaurus is a genus in the family Nodosauridae of the suborder Ankylosauria. This armored dinosaur species was one of the last of the Nodosaurids found during the Late Cretaceous Period. The region of existence of these dinosaurs is the present area of North America.

This is proved by the accumulation of fossils of these dinosaurs from Alberta, Canada, and Texas, United States. The Nodosaurids probably lived in coastal plain flatlands near ancient mid-continental seaways. The diet consisted of low-lying vegetation and plants.

Panoplosaurus mirus is the only species in the genus Panoplosaurus. The species was named by a Canadian Palaeontologist named Lawrence Lambe (1919).

The name Panoplosaurus mirus was given on the basis of Greek words which actually means 'completely armored lizard'. These dinosaurs were not very big and were of medium size when compared to some other related dinosaurs. These dinosaurs were only about 16 ft (4.8 m) long.

These dinosaurs of the late cretaceous period were known to exist around 66 million years ago. The dinosaurs belong to the group of armored dinosaurs called nodosaurs.

The upper parts of the bodies of these dinosaurs were covered with bony plates (looking like a saucer) embedded in the skin. These plates are termed armor. Also, all members of the armored dinosaurs have the same body size and proportions.

There is a related species of Nodosauridae called Edmontonia whose body is protected by a row of great, solid spines located on its flanks along with the bony plates. However, members of this group do not possess tail clubs.

Panoplosaurus Fun Facts

What did a Panoplosaurus look like?

Panoplosarus was a heavily armored species, more than other nodosaurs. Some traverse bands of studded plates were probably covering its back and tail. But the tail did not possess the club common in other ankylosaurids.

Bony armor covered the shoulders, neck, and front limbs. The design of this armor was with a prominent curved ridge on the outer surface. Other nodosaurs have spikes on the shoulders, but these spikes are found absent in the Panoplosaurus.

The head had a helmet-like shield. Bony cheek scutes were also found. A short and wide at the back skull was also said to be present.

Among the specimens found, one had a rounded head and the others longer and flatter skulls. The snout was particularly narrow. The coracoid was not fused to the scapula and was slender.

The forelegs were found to be heavy with probably large muscles. The hand had three fingers. There were four sacral vertebrae with short sacral ribs to which the pelvis was attached.
