đại bàng khổng lồ Argentina - Argentavis magnificens
A North American team has studied the flight abilities of Argentavis magnificens, which lived six million years ago in Argentina.

With its seven-metre (23ft) wingspan, the animal must have been an expert at riding thermals and updrafts.

But, the team tells PNAS journal, at 70kg (155lbs) it might have struggled to get airborne by flapping its wings
