Exceptionally preserved fossil gives voice to ancient terror bird

A new species of South American fossil terror bird called Llallawavis scagliai (“Scaglia’s Magnificent Bird”) is shedding light on the diversity of the group and how these giant extinct predators interacted with their environment. The new species, described in the latest issue of the Journal of Vertebrate Paleontology, is the most complete terror bird ever discovered, with more than 90% of the skeleton exquisitely preserved. The new specimen also reveals details of anatomy that rarely preserve in the fossil record, including the auditory region of the skull, voice box, complete trachea, bones for focussing the eye, and the complete palate, allowing an unprecedented understanding of the sensory capabilities of these extinct predatory birds. —> Read More
