Putting aside the si-fi explaination (I beleive in some of that ) . It looks very much like the black bear print we see here . There are bears in Texas and with the weather and storms you have been having ,they could be changing their migration patterns. Not to scare you but I would be a little more aware of your surroundings until any thing is confirmed or denied.
The weather here has stirred up unusual patterns here also I'm sure you all have heard about the people that were mauled here at the park where I work, thoses petular bears were from another range in the park. Scarcity of food have caused the movemnet in to other bears rangees. I wouldn't leave any foods out side and like I said be aware of things around you. This is just plain good advice for all of us any way.
