Scientists have discovered a strange dinosaur with armor and almost 1 meter long spines on its neck.
Spicomellus afer lived about 165 million years ago and is the oldest example of armored dinosaurs called ankylosaurs.
For experts, the sight of the animal found in Morocco is shocking because they now have to research again how these animals evolved.
"It's one of the strangest dinosaurs ever discovered," Professor Richard Butler told the BBC.
"We don't see it in many animals, living or extinct. It's covered in strange spines that also come out of its back, a bony neck and a kind of weapon at the end of its tail, so it's an unusual dinosaur," added his colleague Susannah Maidment.
According to Butler, ankylosaurs lived in the late Cretaceous period, about 145-66 million years ago.
At the end of this era, large predators like Tyrannosaurus rex emerged, so it was thought that ankylosaurs initially had small, simple plates on their backs that later became larger and stronger to defend themselves from these predators.

"Instead, we have an animal with hedgehog-like spines, the strangest shield we've found on an animal and very different from what we've seen in late ankylosaurs."
Scientists don't have enough parts of the skeleton to be sure of the animal's size, but they think it must have been about 4 meters long and 1 meter high, weighing 2 tons.

This discovery opens up the possibility that ankylosaurs may have had a strong shield in the early Jurassic period and evolution made them simpler and more functional.
The fossil was found by a local farmer in Boulemane, Morocco. It is the first ankylosaur to be discovered on the African continent.
