Fossil Bi-valve

A fossil bi-valve from my collection.

I must say this stuff is pretty cool! I have done some recent research on it since you started posting this stuff. Did you find these yourself?

All of my fossil invertebrates so far were found and collected by me, most had to be busted out of larger rocks.
The geologic time scale for my area would be somewhere in Tertiary which could be all over that time scale but not extremely old. I think a few places north do go into Cretaceous but generally not much in the southern section of my state.
I would like to find some fossil insects impressions in stone, but no luck.

Yeah, some fossil insect impressions would be cool, From what i nave read so far they are Very hard to find, as i am sure you are aware of.

Yep insects do not hold up very well to be a fossil, a good insect fossil print in stone are hard to find but some good ones do exist, and we don`t know what has not been found yet. One science paper I read said insects go back 350 million years.
