Remains of a flying reptile called the "Dragon of Death", which lived about 86 million years ago, have been found in Argentina.

In an interview with the BBC, the scientist, who was involved in the discovery of reptiles with wingspan of 9 meters, said that the size of the predator has a "terrible appearance".

"This species has a giraffe-like size, and its wings challenge the boundaries of our biological understanding," said Leonardo Ortiz, a lead researcher.
