Believe it or not, Johnny Hart's B.C. characters were animated...several times, in fact.
To start off with, here's are these two ACTION commercials.
There were several other commercials from various companies that are very rare.
In addition, B.C. had two holiday specials. A Thanksgiving one and a Christmas one.
In fact, the Thanksgiving special is on YouTube as well.
Both specials were put out on VHS, but are out of print. You can probably find used copies on some online stores, tho...
