Teeth marks suggest 'terror bird' was killed by reptile 13 million years ago

The article discusses the discovery of teeth marks on the fossil remains of a "terror bird" that lived approximately 13 million years ago. Terror birds were large, flightless birds known for their powerful legs and hooked, flesh-ripping beaks. The fossilized remains, found in Argentina, suggest that the terror bird was killed by a large reptile, possibly a crocodile or an early relative. The presence of distinctive teeth marks on the terror bird's bones provides evidence of this predatory interaction. The discovery offers insights into the complex ecosystem and food chain of the time, where these formidable avian predators were themselves vulnerable to larger reptilian threats. This finding adds to our understanding of the evolutionary dynamics and ecological relationships that existed in the past, shedding light on the diverse and often surprising interactions between different species in ancient environments.
