List of megafauna discovered in modern times

The following is a list of megafauna discovered by science since the beginning of the 19th century (with their respective date of discovery). Some of these may have been known to native peoples or reported anecdotally but had not been generally acknowledged as confirmed by the scientific world, until conclusive evidence was obtained for formal studies. In other cases, certain animals were initially considered hoaxes - similar to the initial reception of mounted specimens of the duck-billed platypus Ornithorhynchus anatinus in late 18th-century Europe.

The definition of megafauna varies, but this list includes some of the more notable examples.
