I take Genesis 1-2 to be explaining how God ordered the cosmos to function, not about its material manufacture. Therefore it doesn't say anything about the process He used or the duration employed, leaving the door open for science to tell us such things. Science tells us what happened and how; the Bible tells us why it happened. Therefore, the Bible is open to conversations about process (the Big Bang) and evolution. If this perspective is true, and I believe it is, then Adam and Eve were not the first humans, but instead the first humans to whom God revealed Himself, and the first humans who were ensouled. Therefore, everything we read in science about early pre-humans and dinosaurs is likely correct, within the confines of how science will continue to learn and change with continuing discoveries. So the Neanderthals, homo-erectus, homo-etc., and Denisovans are all real and pre-human, and therefore before the biblical story. The biblical story kicks in (I would say) around 6000 BC) where God revealed Himself to Adam and Eve. Dinosaurs, then, are also pre-biblical. By the time the narrative of the Bible begins, the dinosaurs are long gone. The Bible doesn't mention them (despite what some people will say about Leviathan and Behemoth).
