stone tools found

[camdelcie1]

I found these stone tools in a field in Rio Grande City, TX. I would like to get help from our community to identify and determine the age of these stone tools. Your time and help is appreciated. Thanks and have a great day.

And those 2 stone tools, I found them in the state of Tamaulipas, Mexico. Take a look and share your opinion. Thanks

Any idea about how old can be those tools?
