A ‘one of a kind’ fossil discovery could transform our understanding of how the unique brains and intelligence of modern birds evolved, one of the most enduring mysteries of vertebrate evolution.

Researchers have identified a remarkably well-preserved fossil bird, roughly the size of a starling, from the Mesozoic Era. The complete skull has been preserved almost intact: a rarity for any fossil bird, but particularly for one so ancient, making this one of the most significant finds of its kind.

When Fat Bear Week witnessed the bear attack between male bear 469 and female bear 402, they had to delay the week. While it was not fun to watch, it could have been normal behavior.

Researchers confirm the terror bird fossil 20 years after its South American discovery, comparing the creature to a massive, carnivorous-like ostrich.
