Fascinating discovery in the world of paleontology! A recent study has revealed a previously unknown species of terror bird that could reach heights of up to 12 feet tall. This massive predator lived during the Middle Eocene and Late Pleistocene era, around 43-0.1 million years ago. The study's authors analyzed a fossilized left tibiotarsus (lower leg bone) from Colombia's Tatacoa Desert, which suggests that this species was around 5-20% larger than any previously known terror bird. Interestingly, the fossil also bears teeth marks, indicating that even apex predators like terror birds may have encountered competition.
