A new species of dinosaur has been found in Morocco, immediately after scientists found an “abnormal” fossil was thought to be at the very least 20 million decades more mature than equivalent styles previously uncovered.
The fossil of an ankylosaur rib has a collection of spikes on it and was discovered at the Boulahfa web site in the Center Atlas mountains.
Ankylosaurs had been a herbivorous team of dinosaurs, identified for armoured tank-like bodies and a club-shaped tail top.
Dr Susannah Maidment, a palaeontologist at the Purely natural Background Museum, stated existing ankylosaurs fossils have been dated back to the Cretaceous period of time – around amongst 145.5 and 65.5 million a long time back.
But this discovery is all over 165 million many years previous, dating back to the Jurassic era.
“This is a new species of ankylosaur, it can be a great deal older than any other ankylosaur that we’ve discovered, but also it has this genuinely, definitely peculiar morphology,” Dr Maidment mentioned.
“This fossil is about 165 million yrs outdated. It really is from the Center Jurassic, a time period of time wherever we have truly barely any proof of ankylosaurs at all.”
The Ankylosaurs species has been characterised by a collection of bony plates and spikes embedded in its pores and skin.
The new fossil – in depth in the journal Character Ecology and Evolution – is the initially discovered in Africa and demonstrates prolonged spikes connected to the bone, which Dr Maidment mentioned is “abnormal”.
“This specimen really has spikes and an osteodermal plate fused to a rib – so it really is hooked up firmly to the rib and could not have occur apart,” she reported.
“That is truly unusual. We you should not see that in any other ankylosaur, and in simple fact we will not see that in any other vertebra that we know of, living or dead.”
Dr Maidmont acquired the rib from a fossil seller in Cambridge in 2019.
The new species has been named Spicomellus afer – Spicomellus suggests collar of spikes, and afer signifies “of Africa”.
Specialists at first thought the new fossil was a stegasaurian dinosaur, as stegosaurs have been identified at the web page before, but more examination confirmed it was in fact an ankylosaur.
