Researchers find Fossils of New Species of Terror Bird

There was a time when South America was home of a number of 'terror birds'. They ruled over the place for tens of millions of years before they went extinct about 2.5 million years ago. Now, researchers have found fossils of a new species of terror bird called Llallawavis scagliai. According to the researchers, the species of the bird was about 10 feet tall. They also said that the terror bird lived in Argentina about 3.5 million years ago.

According to reports, fossils of carnivorous birds were discovered by researchers from the Centro de Investigaciones en Ciencias de la Tierra and the Universidad Nacional de Cordoba in Argentina. The fossils were found with hooked beaks standing 10 feet tall. The reports stated that it was the most complete fossil of terror bird ever found. About 90% of the bird's skeleton was preserved. Researchers hope the skeleton will provide valuable information about the bird.

As per the researchers, "The specimen has revealed new details of anatomy that are rarely preserved in the fossil record. This includes the auditory region of the skull, the voice box, trachea, eye bones and palate". They also said that the skeleton of the bird helped them to make an unprecedented understanding of the sensory capabilities of terror birds. The fossils can also be helpful in understanding ecology of the bird.

The researchers stated that the Llallawavis scagliai was able to hear very low frequency sounds compared to other birds. According to them, they also discovered that the bird communicated with low-frequency noises, which means that the bird hunted its prey by listening out for footsteps.

The researchers said that they had CT scans of the bird's inner ear structures which suggested that the bird likely produced kinds of ostrich-like sounds.
