The "archaeologist" in the video is Carl Baugh who is not a scientist and whose PhD in theology seems to be a fake:

The real experts who have examined the Paluxy prints identify them as dino prints next to dino prints. In a few cases, someone has carefully gone in and carved out one of the prints to make it look human. It's not just that this is a small fraud. The real scientists recognize this as an OBVIOUS hoax.
