GROW DINOSAURS

We literally have an entire trilogy of movies that explain why that is a bad idea.

DO IT ANYWAY

okay so now de-extinction is a real thing but why not dinosaurs tho? :(

Dinosaurs show their true colours for the first time

Scientists have recreated the colourful plumage of some of the earliest dinosaurs to grow feathers in research that shines fresh light on the evolution of the beasts.

The flesh-eating Sinosauropteryx, which lived 125m years ago, sported a mohican-style crest on its head and a racoon-like tail marked with alternating russet and white stripes, researchers say.

Paleontologists reconstructed the hues of the dinosaur’s coat after discovering pigments preserved in fossilised remains of the creatures. It is the first time fossil hunters have known the true colours of a dinosaur.

Scientists at Bristol University and the Chinese Academy of Sciences in Beijing analysed  fossils of Sinosauropteryx unearthed in the Jehol rock beds in northeast China. The rocks have been dated to between 131m and 120m years old.

The knee-high Sinosauropteryx, a less fearsome cousin of Tyrannosaurus rex, stood on two legs and had an early version of feathers, made of bristles as long as a fingernail. The metre-long creature used its tail for balance when running.

The colourful tail stripes led researchers to believe that feathers evolved primarily for ornamental reasons and only later became adapted for insulation and flight.

Sinosauropteryx had short, muscular forearms and powerful claws to grasp prey. The creature fed on early lizards and cockroach-like insects that were plentiful in the Florida-like environment of the region. Its jaws were lined with tiny, sharp teeth used to pierce flesh.

Professor Michael Benton, who led the study, examined the remains of bristles under an electron microscope and found tiny structures called melanosomes that contain melanin, a common pigment found in human skin.

In modern birds and mammals, different kinds of melanosomes produce black, grey, orange and brown tones. Black colouration comes from sausage-shaped melanosomes, while spherical ones produce an orangey brown.

Samples from Sinosauropteryx show its tail had bands of melanosomes which produced white and orange rings. The technique gives paleontologists a way of mapping the colours of feathers across the whole body of a dinosaur.

"Two things we thought we would never know about dinosaurs were the noises they make and their colours. We’ve discovered evidence that can tell us for sure some aspects of colour in dinosaurs," Benton said. The research is published in the journal, Nature.

In birds, bright colours are always associated with display, with the tail of the peacock being an extreme example. The colours are used to attract mates or to frighten off rivals or predators. “From the fact that Sinosauropteryx has a stripey tail, we would say that it’s a display function,” Benton said. “It’s clearly not for flight because these are just short bristles.

"What we don’t know is how substantially the body was covered in feathers. The whole body may have been covered in feathers or maybe not. If it was not, then display is the primary purpose."

The team also found melanosomes in the feathers of a primitive bird, Confuciusornis, recovered from the same rocks. Pigments in the feathers suggest it was covered in patches of black, white and brown. The pigments survived for millions of years because melanosomes are made from tough proteins that are hard to break down.

The multicoloured plumages of modern birds are produced by a variety of pigments that are not as hardy as melanosomes. These pigments, which are responsible for flashes of red, purple and green in many birds, may have evolved in early dinosaurs but are too fragile to be preserved in fossils.

"We’re giving a minimum palette. There could be more colours, including flashes of purple and green, that we haven’t been able to see," said Benton.

The team plans next to look for arrangements of melanosomes that produce striking iridescent blues and greens in modern birds such as the kingfisher.

Last year, scientists at Yale University in Connecticut studied iridescent colours in a 40m-year-old bird fossil. The wings changed from a metallic green to blue or copper depending on the viewing angle.

Chances of determining the colour of scaly dinosaurs, like those depicted in the BBC series Walking With Dinosaurs, are slim, since skin and fur is not preserved in their fossils.

Chinese feathered dinosaurs

China’s dinosaur excavations began in the 60s and more than 50 tonnes of fossils have emerged from 30 sites around Zhucheng. 

Guanlong – ‘A very strange primitive tyrannosaur with a huge crest on its head,’ says Professor Xu Xing. Found in northern Xinjiang, Guanlong dates from the late Jurassic, predating T Rex by about 95 million years

Meilong – ‘A lovely dinosaur, very small’. It was found in Liaoning and dates from the early Cretaceous. ‘Very rarely do fossils preserve behavioural information, like how the animal slept – this was one of them. It preserves a sleeping posture very similar to modern birds’

Limusaurus – ‘It’s not only the first Jurassic toothless therapod dinosaur, it also has a highly reduced first finger.’ Xu believes it helps to explain how dinosaurs lost their fingers and bird wings evolved. Found in western China

Incisivosaurus – ‘It has very bizarre front teeth, a bit like a rabbit,’ says Xu. It is a herbivorous theropod, perhaps a metre long, from the early Cretaceous. Found in Liaoning province

Gigantoraptor – ‘Normally, oviraptors are very small. No one expected one with a size comparable to some tyrannosaurs [more than 8 metres long], and it has many interesting features.’ Found in the Gobi desert, it dates to the late Cretaceous

Feathered dinosaur fossils find has Chinese scientists all aflutter
New discovery unearthed in rock formations in north-eastern China confirms birds evolved from dinosaurs, scientists claim
The discovery of five remarkable new fossils has confirmed that birdsevolved from dinosaurs, Chinese scientists said last night.
Because the fossils, unearthed in north-eastern China, are older than previous discoveries of similar creatures, the find adds weight to the theory that birds descended from predatory dinosaurs.
The fossils all have feathers or feather-like structures. The clearest and most striking of the specimens can be seen to have four wings, extensive plumage and profusely feathered feet.
One of the scientists who made the discovery, Xu Xing, will reveal details of his find in Bristol at the annual meeting of the Society of Vertebrate Palaeontology.
"These exceptional fossils provide us with evidence that has been missing until now," Xu said. "Now it all fits neatly into place and we have tied up some of the loose ends."
The finds date back to between 151m and 164m years ago, which suggest they are older than archaeopteryx, previously thought to be the oldest undisputed bird.
Xu, who is based in Beijing, said: “The fossils provide confirmation that the bird-dinosaur hypothesis is correct, and supports the idea that birds descended from theropod dinosaurs (the group of predatory dinosaurs that includes allosaurus and velociraptor).”
The fossils were found in Liaoning province. Xu told the Guardian he was shocked when he first saw the best of the specimens. “This was really unexpected. One thing that would shock you is that this is covered with feathers everywhere except the beak and the claw,” he said. “It is the first feathered species known so far; the earliest known feathered species.”
There have been fakes before. A creature that came to be known as archaeoraptor, with the body of the bird and the tail of a dinosaur, sent the world of palaeontology into a flutter after apparently being found in China. It was later proved a fake, not unearthed by scientists, but bought at a rock show in the US. China is an increasingly important centre for palaeontology because so much of the country’s rocks remain unexplored. A sizeable contingent from China is attending the conference in Bristol, one of the largest gatherings of palaeontologists ever.
Xu said: “The first question we wanted to know was is it fake or real? We checked in detail and convinced ourselves there was no problem. We are 100% sure we are looking at a real species, not a fake one. It’s one of the most important for understanding the origin of birds.”
Feathers cover the arms and tail, but also the feet, suggesting that a four-winged stage may have existed in the transition to birds. The fossils will also help scientists work out the mechanics of how early birds flew. The specimens have been identified as types of Anchiornis huxleyi. The details of the find will also be announced in Nature. View high resolution
