I'm looking for an 80's or 90's cartoon. My memory is vague, but I believe it had a purple dinosaur that had the ability to punch holes in metal (it had round teeth). Also there was a yellow pterodactyl (In think) that could cut through metal like scissors. There were other coloured dinosaurs in the group and I believe at least one human, although I could be mistaken.

Any light on this would be useful. Thanks.
