N THE 1990s, any book, teacher or scientist would have told
you we’d never be able to tell anything about the colour of
extinct animals such as dinosaurs. The best we could ever do
was make comparisons with living creatures, and often reptiles
were deemed to be the best proxies. Most dinosaurs were painted
in shades similar to those of crocodiles or monitor lizards – greys,
greens and browns.
It seems puzzling now when you think about it. Birds and
mammals – from fairy wrens, peacocks, parrots and cassowaries,
to tigers, tree kangaroos, baboons and red pandas – boast a large
range of vibrant shades and hues, and even many lizards – from
chameleons to anoles – have striking patterns of colouration.
Since the discovery in China in 1996 of the fi rst feathered
dinosaur, Sinosauropteryx (more than 40 feathered species have
now been discovered, suggesting that most carnivorous dino-
saurs had feathers), the assumption had been that dinosaurs
might have had some of the same vast variation in plumage that
birds do today, but few people believed such a thing would ever
be confi rmed.
That was until January 2010, when a remarkable paper in
the scientifi c journal Nature suggested that Sinosauropteryx had
sported ginger and white stripes around its tail, perhaps some-
thing like the pattern found on ring-tailed lemurs today. “Oh
no, it’s Ginger-saurus! For fi rst time scientists uncover colour of
dinosaur and it was...a redhead” was one headline, in the UK’s

Daily Mail newspaper. The report went on to say: “As if its short
stature and ugly feathers weren’t enough to give it an inferiority
complex, one of the world’s best-preserved dinosaurs now turns
out to have been ginger.”
A jaunty illustration painted by Chuang Zhao and Lida Xing,
and released when the discovery was announced, depicts two
cheeky-looking, ginger-fl uff ed Sinosauropteryx. Their heads are
thrown back and each is cavorting on a single leg with arms fl ung
wide to impress or perhaps intimidate the other (Lida Xing is
the illustrator of the Australian dinosaurs poster, which is free
to subscribers with this issue).
The 2010 research study, from scientists in China and the
UK, also revealed black, white and orange-brown colouration
on the early bird Confuciusornis. Similar work has now revealed
the feather colours of Archaeopteryx and of four-winged fl ying
dinosaurs Anchiornis and Microraptor. These discoveries have
opened up a novel fi eld of research, allowing palaeontologists
to delve back more than 100 million years and probe the lives
of dinosaurs and early birds.
“Feathers are key to the success of birds and we can now
dissect their evolutionary history in detail,” Professor Mike
Benton, one of the experts behind the work at the University
of Bristol, told reporters. “The simplest feathers, in dinosaurs
such as Sinosauropteryx, were only present over limited parts of
its body – for example, as a crest down the midline of the back

Jurassic looker. Found in China in 2009,
150-million-year-old Anchiornis huxleyi
had long feathers on its hind- and
forelimbs. Fantastically preserved fossils
have allowed the feather colour to be
reconstructed, showing it was black with
white speckling and had a red head crest.
