Wikipedia -- Cretaceous–Paleogene extinction event
K–T extinction, abbreviation of Cretaceous–Tertiary extinction, also called K–Pg extinction or Cretaceous–Paleogene extinction, a global extinction event responsible for eliminating approximately 80 percent of all species of animals at or very close to the boundary between the Cretaceous and , about 66 million years ago.
Why not 79% or 75% or even 50%? and who says they had to all go in an instant? Rather why not have the K-T be it's own era? a 100,000,000 year event that see the end of paleogene periods and the introduction of a few others..
Because if the period ends with a meteor or some quick flash done event, and everythng but a small few survive, that would mean evolution had to work overtime to introduce the next era. OR let say the dominant creatures who were kings after the k-t extinction actually existed durning the paleogene periods?
Again we have example who lived through those periods and are alive now!
The iridium layer marks the boundary. No "dino" fossils above it. Very clear demarcation.
