Scelidosaurus (198-188 mya)

«lizard with ox ribs», a designation given by mistake. It was originally intended to be named Scelodosaurus, which would have meant «hind-limbed lizard», but a single letter was accidentally confused.

Scelidosaurus lived about 190 million years ago, during the Early Jurassic. It was a herbivorous ornithischian dinosaur that moved on four limbs. Its back was covered by a strong bony armor, providing reliable protection against predators. It reached about 3.5 meters in length and weighed roughly 300 kilograms.

Scelidosaurus inhabited islands covered with dense forests in what is now northern Europe. The climate at the time was mild and humid, and the landscape was a varied mixture of plains, coastal swamps, and low hills. These dinosaurs fed mainly on ferns and cycad-like plants resembling modern palms.

After death, the bodies of Scelidosaurus were often carried out to sea, where they became buried in sedimentary deposits and preserved for millions of years, awaiting discovery. Today, one of the most complete Scelidosaurus skeletons can be seen in the Natural History Museum in London, offering a unique glimpse at one of the earliest armored dinosaurs.

Scelidosaurus belongs to a distinctive group of ornithischian dinosaurs known as thyreophorans. This clade also includes the later and more famous stegosaurs and ankylosaurs. Paleontologists consider Scelidosaurus to occupy a key position in their evolution. Even if it was not a direct ancestor of these later giants, it was undoubtedly close to their common evolutionary origin.
