Help ID

[EdNargel]

When I go to Western Indiana I enjoy walking river beds looking for cool rocks, geodes and fossils. I am able to ID most of the common fossils that I find such as brachiopods, Crinoids etc, but here are some pics of some that haven't been able to ID. I think that a couple of them are fossilized coral and someone told me that the small brown pointed one might be a Mosasaurus tooth any thoughts? Thanks!!!

In Western Indiana, you're hunting Paleozoic rocks (Silurian, Mississippian, or Pennsylvanian). At your latitude, one of the latter two. Mosasaurs are Mesozoic -- too late for where you're hunting.

Corals are notoriously difficult to ID from an image.

No, Ed, I don't know what your first object is. I recommend FOSSILS OF OHIO, Bulletin 70 of the Ohio Geological Survey, for help in identifying your fossils.

When I lived briefly in Danville, Illinois, I used to do the same sort of fossil hunting as you are doing. The Ohio guide would have been enormously useful to me then, and I think it will help you.

The Carboniferous is too early for tortoises also.

bulletin 70 looks interesting, but they want 30 bucks plus shipping.

It is an investment in yourself; your knowledge is the only possession no one can take away from you. At $30, this book is a huge bargain! But . . . a bargain only if you want to learn.
