We usually see ancient plants or insects in amber(琥珀). But recently, a group of researchers found something unusual in amber — a feathered tail!
The tail includes bones, soft tissue and even feathers. It is 37 mm long, which is about the length of a matchstick. It looks like a plant at first sight. But researchers later identified(确定) it as part of the tail of a dinosaur that couldn’t fly almost 100 million years ago.
Xing Lida of Beijing’s China University of Geosciences discovered the amber in a market in Myanmar in 2015. “It is an amazing fossil(化石) and the finest details of feathers can be seen in 3-D.” he said.
The researchers note in their paper that this finding is particularly special because, although dinosaur feathers have been found in amber before, we don’t know which dinosaurs they came from. But this time researchers know more.
The tail is likely to belong to a tiny dinosaur called coelurosaur. Famous coelurosaurs include the T-rex(霸王龙) and Velociraptor(迅猛龙) — the latter of which would finally evolve into birds.
So with the “once in a lifetime” finding, can we hope for the possibility of a real Jurassic Park (侏罗纪公园)? In the movie series, scientists bring dinosaurs back to life by getting their DNA from blood found in amber.
But Canadian scientist Ryan Mckellar said that although soft tissue and blood of the tail were found in the amber, no genetic material was kept. “The Jurassic Parkanswer is still a ‘no’ — this is in the science fiction.” he said.
