Most oil available today formed from carbonaceous era biomatter that was buried or stored anoxically before cellulose digestion evolved, and 70% of reserves were available 252-66 million years ago. Dinosaur civilization would have had access to oil. If it did exist it wasn't industrial. Probably no settlements at all, since we'd be able to identify graveyards (if they buried their dead, which occurs in nature without the dedicated land lots) and midden heaps. Middens particularly would be perfect fossilization environments since they're typically anoxic and tend to become strata over time. We've left a bigger global impact in the strata than the K-T line that marks the sudden end of all dinosaur fossils.
I am deeply impressed somebody here had that on deck. I don't know if I agree with your claim about lack of settlements just based on the ammount of speculation we'd have to out in that one. The rest seems just spot on though.
