An interesting article on how the exact moment in which the dinosaurs fell into extinction (the infamous K-T Event) is being determined using the argon-argon technique:

La extinción de los dinosaurios no puede ubicarse en un momento concreto, solamente el suceso que dio inicio al fin de algunas (o muchas) especies de dinosaurios podría llegar a datarse, porque la extinción de las especies es algo gradual, siempre y cuando no intervenga el hombre (el cual tiene la capacidad de exterminar especies casi instantaneamente). De todas maneras los dinosaurios nunca se extinguieron, evolucionaron, de otro modo nunca hubiesen existido las aves. Miren las patas de cualquier ave y se sacan la duda.
