Three of the oldest are the Acasta Gneiss in Canada, the Yilgarn Craton in Australia, and the Isua Greenstone Belt in Iceland.These formations may range from 3-4 billion years of age.

Where could dinosaurs be found?

Pfft, all over the world really, but I've read something about a "history" line in rocks. Apparently, fossils of dinosaurs can only be found below that line. Take Drumheller, Alberta, for example. The rock formations have lines on them. Many dinosaurs have been found in similar rock formations. It is rare to find any higher up on the rock. Most "rock" formations dinosaurs are found in aren't really solid rock, but sedimentary dust and debris piled up over the years(and years...and years...). So unless the fossil had been exposed a few decades ago, but then had dust and debris pile up on it for a short time, dinosaurs can usually be found in lower canyon-like rock formations. (I'm no expert, but I have been very interested in dinosaurs and over the years have collected quite a bit of information.)

They look for rock formations where oil would be found. They locate those underground rock formations using seismic equipment that bounces a sound wave off rock formations, and back to a receiver. Somewhat the same way that sonar is used to locate a submarine underwater.
