BBC : The most complete skeleton discovered so far of a prehistoric “terror bird” has been uncovered in Argentina. Terror birds, which were carnivorous and flightless, stood up to 3 m tall and had huge skulls, large hooked beaks, and long hind limbs. They lived primarily in South America, about 62 million to 3.5 million years ago. The newly discovered specimen represents a new species, which has been called Llallawavis scagliali, after one of the discoverers, Fernando Scaglia. The skeleton is 90% complete. Because its skull was well preserved, researchers have been able to reconstruct the shape of its inner ear and thus determine some of the bird’s sensory capabilities. They say that its apparent sensitivity to low-pitched sounds probably indicates it also produced low-pitched sounds.
