A new chicken-sized dinosaur with flamboyant features used to attract mates or intimidate foes has been discovered.

Ubirajara jubatus, which lived about 110 million years ago, had elaborate plumage including a long fur mane and stiff ribbons projecting from its shoulders.

Researchers said these shoulder ribbons were not scales, fur or feathers and are believed to be unique to the animal. Each had a small sharp ridge running along the middle.

Scientists excavated the specimen from two slabs of stone and, using X-rays, found previously hidden skeletal elements and soft tissue – including a section of the long, thick mane running down the animal’s back that was preserved nearly intact. The arms were also covered in fur-like filaments down to the hands.

1. he looks nice.

one thing about birds that continues to fascinate me is that they solve their conflicts w displays and songs, not violence.
because of the fact that their hearts beat so fast, a small wound can lead to bleeding to death. so they just sing and dance to settle their territorial/mating disputes.

looks like at stuff started very early in their evolution. i can only imagine what they did w those 'ribbons'. it's cracking me up.

2. Jurassic Park

Had something similar in first one. Mean MOFO's! Haha

3. Potentially an adaption that has venom and or poison from something that it ate on a regular basis

kind of like some poisonous frogs?

4. WHERE was this fossil found?

AFAICT, the article never mentions what part of the world the stone that housed the dinosaur came from. They gave it an Indian name but say that it is closely related to Compsognathus, a European species.

Did I miss something?

BTW, very cool dino. Love the porcupine-ish "quills".

5. Ah ha!

Think I found where the fossil was from and why, probably, it wasn’t mentioned in the article.

Here’s a YouTube channel I recently found and subscribed to:

This is a general science news segment they call 7 Days of Science. At 3 minutes they cover this discovery. Right at the end of the segment the presenter mentions that it’s thought the fossil was from Brazil, but probably removed illegally. That’s a bummer.

Still a cool dino.

6. 'Like nothing seen in nature before': strange dinosaur has scientists enthralled

The highly unusual Ubirajara jubatus boasted a mane of ‘hair-like structions’ and two ‘ribbon-like features’, researchers say

About 110 million years ago along the shores of an ancient lagoon in what is now north-eastern Brazil, a two-legged, chicken-sized Cretaceous period dinosaur made a living hunting insects and perhaps small vertebrates like frogs and lizards.

On the inside, it was ordinary, with a skeleton similar to many small dinosaurs from the preceding Jurassic Period, scientists said on Tuesday. On the outside, it was anything but.

This dinosaur, called Ubirajara jubatus, possessed a mane of hair-like structures while also boasting two utterly unique, stiff, ribbon-like features probably made of keratin – the same substance that makes up hair and fingernails – protruding from its shoulders.

“There are plenty of other strange dinosaurs, but this one is unlike any of them,” said David Martill, a paleobiology professor at the University of Portsmouth in England, who helped lead the study, published in the journal Cretaceous Research.

7. Cretaceous Dinosaur Had Impressive Mane and Shoulder Ribbons

Dec 16, 2020 by News Staff

A maned theropod dinosaur with elaborate filamentous structures has been identified by a research team led by University of Portsmouth paleontologists.


The newly-discovered dinosaur species lived about 110 million years ago (Aptian stage of the Cretaceous period) in what is now Brazil.

Named Ubirajara jubatus, the ancient animal was chicken-sized with a mane of long fur down its back.
It also had long, flat, stiff shoulder ribbons of keratin, each with a small sharp ridge running along the middle. Its arms were covered in fur-like filaments down to the hands.

“What is especially unusual about the beast is the presence of two very long, probably stiff ribbons on either side of its shoulders that were probably used for display, for mate attraction, inter-male rivalry or to frighten off foe,” said co-author Professor David Martill, a paleontologist in the School of the Environment, Geography and Geosciences at the University of Portsmouth.

“We cannot prove that the specimen is a male, but given the disparity between male and female birds, it appears likely the specimen was a male, and young, too, which is surprising given most complex display abilities are reserved for mature adult males.”
“Given its flamboyance, we can imagine that the dinosaur may have indulged in elaborate dancing to show off its display structures.”

Ubirajara jubatus’ mane is thought to have been controlled by muscles allowing it to be raised, in a similar way a dog raises its hackles or a porcupine raises its spines when threatened.
