Possible Horse/cow fossils?

[Phillipku2001]

Hey guys new to the forums and thought I’d make a post to have you guys help identify some possible fossils that i found in a local creek after heavy rains.There are lots of mission era ranches so there is a possibility of them being old but not fossilized cow bones. Let me know what you guys think

I see three cow teeth and one senile equus horse tooth.  I'd guess not fossils.
