The Munchers: a Fable (1973) by Art Pierson

This clip is somewhat of a mystery. Supposedly directed by Arthur P. Pierson, the film nor the director are listed at imdb. The http://www.afana.org/ showed both films during the 2000s:

• Munchers: A Fable’ (1973) 10m, dir. Art Pierson. Clay and polymer tooth puppets bring decay to life.
• ‘Whazzat?’ (1975) 10m, dir. Art Pierson. Here, nondescript clay figures attempt to identify an elephant.

I cannot track any info on this remarkable little film by Arthur P. Pierson. If you know more, please let me know. A further hint is this description of ‘Whazzat?’.
