'Perfectly preserved' Neanderthal skull bones suggest their noses didn't evolve to warm air - Live Science

A tiny piece of amber from Myanmar has captured a defensive maneuver that lizards still use today: shedding part of their tail to escape a predator. The fossil provides direct evidence that this defensive mechanism was already in operation in mid-Cretaceous forest ecosystems. General view of the amber piece from Myanmar, arrows highlighting the debris stuck to the initial resin flow at the level of the ventral surface of the tail.

A newly discovered feathered dinosaur named Norellraptor barsboldi had sharply curved teeth and claws, as well as four wings, and it adds evidence to the idea that flight evolved several times in different dinosaur groups.
