Hi, Cpthiltz.
I wanted to add briefly to what Wounded King said about fossilization.
I work with spiders, so I spend a lot of time on my hands and knees. Everyday, within the confines of a single crop field, millions of insects and other small animals die.
But, as I search the ground, I only occasionally come across insect or worm carcasses. Most are consumed completely and torn to shreds by scavengers, such as ants. Usually, all that I ever see are disarticulated parts (a beetle's head, a dragonfly's wing, the shed exoskeleton of a springtail, etc.).
If I see so little remnants of the deceased the day after it happens, why should I expect there to be a plentiful supply from a hundred million years ago?
