Cro et Bronto (partially lost DiC animated series; 1980)
Cro et Bronto is a French animated series created by Bruno Bianchi (1955-2011). It was DiC's first cartoon before their successful Inspector Gadget in 1983 and moving to the United States in 1987. It ran for 45 episodes which were 1 minute and 20 seconds each.
A caveman called Cro is trying to hunt a brontosaurus but his plans keep backfiring and turning against him. However, Bronto somehow is in love with Cro, and is unaware of his schemes.
The series is similar in spirit to Wile E. Coyote and the Road Runner, except with a caveman and a dinosaur.
Cro et Bronto disappeared from French television screens, and it's considered to be hard to find today. The same goes with animated series Archibald le Magichien (Archibald the Magic Dog) which was Jean Chalopin and Bruno Bianchi's the first major collaboration.
A few episodes have surfaced online; only one is on YouTube. The cartoon was also mentioned in the history-of-DiC book Les séries de notre enfance ("TV series of our childhood") about an episode that is on YouTube and OSIBO Archives. The OSIBO one omitted the intro and credits.
As of today, more episodes of Cro et Bronto have yet to surface online (along with Archibald).
