This screen grab comes from the "Black Scorpion" trailer. The shot does not appear in the "Beast From 20,000 Fathoms". My guess is that it is a model and/or lighting test that Warner Bros. had the negative for and used it without knowing,(or caring) if it was actually a scene from the film. To my eye it seems a little pale compared to the darker grey version we're used to. It almost seems to have a subtle hi-light brushed over to pop out the texture.
