It’s two birds in one stone. Two pairs of
wings belonging to hatchlings that lived
alongside dinosaurs 100 million years ago
have been found in Myanmar by an
international research team.
The fossilised wings have been
immaculately preserved in amber. Each is
just two or three centimetres long and
includes bones, long ‘fingers’ tipped with
sharp claws, as well as individual feathers.
“These fossil wings show amazing detail,”
said researcher Mike Benton. “The
individual feathers show every filament and
whisker, whether they are flight feathers or
down feathers, and there are even traces of
colour – spots and stripes.”
The anatomy of the hand indicates that
the fossils come from enantiornithines, a

major group of birds that died out at the
same time as the dinosaurs, 66 million years
ago. It is likely that the birds wandered out
of their nest before becoming trapped in the
sticky tree sap that eventually solidified to
form amber.
“The fact that the tiny birds were
clambering about in the trees suggests that
they had advanced development, meaning
they were ready for action as soon as they
hatched,” said lead researcher Dr Xing Lida.
“These birds did not hang about in the nest
waiting to be fed, but set off looking for
food, and sadly died – perhaps because of
their small size and lack of experience.
Isolated feathers in other amber samples
show that adult birds might have avoided
the sticky sap, or pulled themselves free.”
