6. Therizinosarus : Claws Of Doom
The Therozenosaurus, known as the “scythe lizard,” inhabited Asia around 70 million years ago. Standing at an impressive 16 feet tall, its most terrifying feature was its one-and-a-half-foot-long claws, the longest claws of any animal ever known. Despite their intimidating appearance, these herbivores used their elongated appendages to reach vegetation within their grasp. While they may not have been fierce predators, their claws would undoubtedly have been a formidable defense mechanism.
