So what happened to our lizard overlords?

Well Stu technically dinosaur/birds and crocodilians are Archosaurs - the sister taxon to Lepidosaurs which are the lizards (along with snakes, worm lizards and the tuataras).
So to be utterly pedantic no lizards were ever our overlords as such (although Mosasaurs the giant marine reptiles most recently seen in Jurassic World (a terrible film for accuracy but ok as a brainless blockbuster)
were overgrown warm blooded, live bearing lizards.
The non avian dinosaurs were finished off by the Chicxulub Crater impact and the Deccan Traps volcanism would have made life very difficult as well.
Wiki is actually pretty good on all this stuff because many articles are written and edited by palaeontologists.
