Identifying and altering certain genes found in modern birds' DNA would mean that genomes of the dinosaurs could be engineered 20 million years after they became extinct, claim scientists.
Oxford biochemist Dr Alison Woollard said theoretically it is possible to recreate the extinct species through DNA, the Mirror reported.
A mosquito was recently found with the blood of another animal in its stomach, dating back 46 million years.
She said that the most famous of these is the Archaeopteryx, a fossil that clearly shows the transition between feathered dinosaurs and modern birds.
Wollard said that this evolution implies that buried deep inside the DNA of today's birds are switched-off genes that control dinosaur-like traits.
