ደስ ዝብሉ ሓቅታት

1

Spicomellus is the first and only ankylosaur ever found in Africa, and it is also the oldest ankylosaur known to science.1

2

Unlike most armoured dinosaurs, Spicomellus had spikes that fused directly to its rib bones. No other animal, living or extinct, has this feature.13

3

Its spikes were probably covered in keratin, the same substance that makes up your hair and fingernails, which would have made them even longer.1

4

Spicomellus had a bony 'handle' in its tail, a feature only seen in ankylosaurs that had a tail weapon. This suggests it had a spiked tail club, even though the weapon itself hasn't been found yet.12

5

Scientists used to think that tail weapons in ankylosaurs evolved only in the Cretaceous Period, but Spicomellus lived much earlier, in the Middle Jurassic. This shows that these features are older than expected.12

6

Spicomellus had a bony collar with metre-long spikes, which is why its name means 'spiked collar'.1

7

The spikes on its body may have been used for defence, but scientists think they were also used for display, to attract mates or compete with rivals.12

ብዛዕባ Spicomellus ብብዝሒ ዝሕተቱ ሕቶታት

?How big was Spicomellus?

About 4 metres (13 feet) long, which is around the size of a small car.1

?What did Spicomellus eat?

It was an herbivore, meaning it ate plants.1

?Did Spicomellus have a tail club?

Scientists think so. It had a bony 'handle' in its tail that is only seen in ankylosaurs with a tail weapon, but the weapon itself has not been found yet.15

?Where did Spicomellus live?

It lived in what is now Morocco, Africa. Back then, the area was a wetland with lots of plants to eat.1

?When did Spicomellus live?

It lived during the Middle Jurassic Period, about 167 to 163 million years ago.1

?Was Spicomellus a dinosaur?

Yes, it was an armoured dinosaur called an ankylosaur.1

?How fast could Spicomellus run?

Nobody knows for sure. It walked on four legs and had a bulky body, so it probably moved slowly.1

ጽውጽዋይ ዘፍርስ

ጽውጽዋይ: Some people think Spicomellus was a slow, simple plant-eater with no special tricks.

ሓቂ: Actually, Spicomellus had unique armour and a possible tail weapon, and its spikes may have been used for showing off as well as protection.12

Spicomellus was named by Maidment and colleagues in 2021, based on a partial skeleton from Morocco. The first fossil was a rib with spikes, and later more bones were found, including a bony collar.13
ገና ዘከራኽር
Scientists are still debating exactly how Spicomellus is related to other ankylosaurs, and whether its tail weapon was a club or just spikes.2
