I saw this movie  couple of years go on TV around Halloween.  It is an old movie.  I can’t remember the title or actors.  Here is what I recall:

Movie was set in new mexico and was fiction/horror

It was in black and white

There was some wild animal attacking people, but no one had seen the animal

The animal scratched trees with his claws, leaving three claw marks I think

There was a scene with a fountain  in it.  The characters commented on the fountain and the ball floating at the top of the fountain on a stream of water

One of characters was a teacher or professor at the University

Thank you for any help you can give
