40 Strange Cave Discoveries That Are Hard To Be Explained
The Broken Beast’s Claw

This is no work of cosmetics on actors for sci-fi movies. When scientists found this in a cave they were also of the same opinion as you but research later revealed that this was a real claw of an ancient beast. This claw is of one of the most dangerous birds that have ever existed. Moa, a bird species from New Zealand might have gone extinct but the mere exploration of its claws open several doors towards more revelations about this breed.
Moa was bigger than any bird species currently existing. They even preyed on humans. Thank God, the beast is no more for us to see.
