If such a civilization developed before fossil fuels were available, then they could've used alcohol from fermented fruit as a fuel source and that would be significantly more prevalent as a source since it's 100% renewable. If they developed larger brains, which I can't imagine they wouldn't considering the intelligence level of your average human, then they could have developed science far beyond modern day science and flown off into space. Lizard people? I highly doubt it, although I suppose that depends on what you call a lizard. Warm-blooded dinosaurs weren't lizards, but many people think they were and I would at least assume it's possible that a species of velociraptors could have developed enough intelligence and disappeared from the planet.
