Which of the following rock types are most likely to have dinosaur fossils: basalt, shale, gneiss, or limes?
It seems lіkе іt ѕhουld bе a sedimentry rock, whісh I suppose wουld eliminate ѕοmе choices. I’m guessing еіthеr shale οr mineral? I’m leaning more toward shale аѕ mineral іѕ mаkе bу deposition іn thе ocean, whісh probably wouldn’t work bесаυѕе dinosours wеrе frequently land based. Anу thουghtѕ?
You are right,. it is shale. Basalt is volcanic and most dinosaurs don’t like to burn their feet off leave-taking tracks. Gneiss is metamorphic and hard as rock. Mineral typically forms as a chemical precipitate or reef and reefs are not conducive to leave-taking dinosaur prints, because they are hard to walk on and waves would wash them away, and deeper mineral sedimentary beds are not where dinosaurs may possibly walk.
You are leaning toward the right answer. The right one being shale. Basalt is made by magma and it would cool too quickly for it to leave any sort of dinosaur footprint, even as gneiss is made underground so that policy that one out. Between shale and mineral you want to look at there different depositional environments. Mineral is generally made nautical environments. Even as shale can be that plus rivers, streams, lakes. Your best bet is certainly shale!
