"Thanks! I'm just getting all sorts of info today!"

Your welcome! :)sss

"So, these extinctions all began a new 'age'? Hmmm. Got to think on that."

Not quite, mass extinctions do not begin the new ages, they occur because after the new age has begun. They are a marker of when the new age started. They occur, because planetary conditions are so different from what they just were that many thing just can't adapt and/or survive. When a mass extinction is noticed in the geologic record, one asks "Why did all these species go extinct?" The usual hypothesis are:

Huge Tectonic event (continental colisions or seperations)
Sudden global climate change

After mass extinctions, an explosion of new species takes place. I.E. reptiles after the P-T, mamals after the k-t
