‘Punk rocker’ dinosaur had lengthy spikes, newly found fossils present

A dinosaur dubbed one of many “strangest” ever discovered boasted an elaborate armory of lengthy bony spikes and a tail weapon, based on findings published within the science journal Nature.

Spicomellus, which roamed the Earth 165 million years in the past, is the world’s oldest ankylosaur, a herbivorous group of dinosaurs recognized for his or her tank-like our bodies.

Palaeontologists’ picture of Spicomellus was primarily based on a single rib bone present in Morocco in 2019.

But newly found stays have helped scientists type a clearer image of the bizarre dinosaur.

The fossils confirmed it had bony spikes fused onto all of its ribs — one thing by no means seen earlier than in every other vertebrate species residing or extinct, based on the analysis printed Wednesday.

Richard Butler, a professor on the University of Birmingham and the mission co-lead, told CBS News partner BBC News that it was the “punk rocker” of its time.

Butler referred to as the fossils an “incredibly significant discovery,” including that “Spicomellus is one of the strangest dinosaurs that we’ve ever discovered.”

Butler’s mission co-leader, Susannah Maidment of the Natural History Museum in London, added that it was stunning that the spikes had been fused immediately onto the bone, the BBC reported.

“We don’t see that in any other animal, living or extinct,” she stated. “It’s absolutely covered in really weird spikes and protrusions all over the back of the animal, including a bony collar that wraps around its neck and some sort of weapon on the end of its tail, so a most unusual dinosaur.”

The discovery is so uncommon that Butler and Maidment are contemplating whether or not the theories on how ankylosaurs advanced ought to be re-assessed.

These dinosaurs survived late into the time dinosaurs had been on Earth, in a interval generally known as the Cretaceous, the BBC reported. The finish of this era noticed the emergence of large carnivorous predators, resembling T. Rex, so it had been thought that ankylosaurs began off with easy, small armored plates on their again, which then turned bigger and extra in depth to guard themselves from these huge beasts, based on Butler.

“If you had asked me what I would have expected the oldest known ankylosaur to look like I would have said something with quite simple armor,” Butler informed BBC News. “Instead, we have an animal bristling with spikes like a hedgehog, the most bizarre armor that we’ve ever found in any animal, far outside the range of armor seen in later ankylosaurs.”
