River finds from North Central Texas. No size reference on the darker one but it is approx same size as the lighter colored one. I'm guessing the light one is some type of prehistoric horse, as it is fully fossilized. The darker I have no idea but it is also fossilized. Any help on either is appreciated. Also found some really cool pieces of petrified wood. Included a couple of pics of those as well. It's hot down here but had a cool trip. Hard to get as much hunting in as you'd like though when it hits 105. Thanks for any info on the teeth?

Cool Finds! Your fossilized tooth looks like it may be from a horse, and the item in your first photo (hard to tell) looks like a fossil plant. Nice petrified wood!

The second object appears to be a horse tooth. The first reminds me of a mammoth spit tooth, but can't say for sure without more images. Here's a spit tooth:

I feel the ridges are too pronounced for it to be mammoth. Maybe gompothere?

Thanks for the replies. The dark fossil did not come home with me but you've put me on the right track I feel. I had to look gompothere. Always good to learn things and add a few more things to my collection.
