what is this? Indian axe head or something else?

I need help finding out what this is. I found it in south Texas along with 12-15 arrowheads and abunch of broken ones. Is it an axe head or something else. You can tell it has clearly been chipped but I'm unsure what it is. It is roughly 4 inches long by 3 inches wide and the non-chipped part is very smooth.

I don't see any evidence of this pc ever being altered by man except on the edge they used for a chopper

that was dedicated to steve "my best friend" Valentine

I love you brother

that's pretty funny right there! Nice work.

This piece is CLEARLY intentionally altered by man. I don't believe there's much room for debate here. But what do I know.
