The Mount Owen Moa Claw
In 1986, a group of researchers went into a cave in Mount Owen on the island of New Zealand only to discover one of the most terrifying and bizarre finds of the 20th century. They discovered a claw with flesh and muscle still intact that looked like it came from a dinosaur. It turned out to be a Moa claw, a long-extinct bird native to the island. Even more mysterious is that it had been extinct for 3,000 years. So, how was the claw so well preserved?
