Phorusrhacos longissimus (Ameghino, 1887)
Phorusrhacidae (Terror Birds)
Height: 2.5 m
Originally thought to be a xenarthran mammal until 1891 (hence the grammatically incorrect Greek genus), this giant predatory bird hunted her prey with terrifying speed and rapid dorsal-ventral cuts from her beak and likely serrated mouth and tongue, similar to modern vultures, petrels, and her more famous dinosaurian antecedents such as Allosaurus fragilis.
