"Does geology show faunal succession?" -- only in the minds of evolution-believers.
World-wide deposits of sandstone, limestone, ash, etc ... contain fossil bones, shells, and teeth of animals that were buried in sediments too quick for them to rot. Hard parts, mud-tracks, and few soft parts are all the evidence geology gives on the history of animals.
Fossils exist in all the layers of sediment-rock from every Phylum of Kingdom Animalia we see alive today (except the pre-Cambrian bottom layer which contains only microbes). This does not show a history of animals having once been all the same type, as evolution theory says. It does show a history of animals having always been different types, as creation theory says.
Groups of animals today have great differences in body plan. We see these same differences in the groups of fossil animals. Evolution-believers look for fossils that might show how these differences didn't exist between animals in the past, as they do now. Such fossils are called "missing-links" ... for a reason.
Sometimes a fossil might look like it has features that could show it is a missing-link. But each candidate is disqualified by features it also has that show it is clearly not. The flying squirrel might look like it has features that could show it is the missing-link between mice and bats, but it is disqualified by features it also has that show it is clearly not. This is the pattern of differences among living animals. This is the pattern of differences among fossil animals. There are living mice and bats. There are fossil mice and fossil bats. There are no mouse-bat fossils. Geology does not show that there used to be just only one type of animal. Geology shows that there have always been many types of animals.
If the Flood of Noah happened today, it would bury fossils in sediment deposits (from the deepest to the top layer) in an order that would go along with evolution theory. It would bury animals of Subphylum Vertebrata (animals with a backbone) in the order ... fish, amphibians, reptiles, birds & mammals. This would be the same order as the elevation of where they live ... which by sheer coincidence would go along with evolution theory. All other animals (Phylum Arthropoda and Phylum Mollusca, including all insects and snails) would also be buried in order of the elevation of where they live. But that order that would be out of sync with evolution theory.
What does geology show today about animals of the past? It shows all animal fossils were buried in an order that was out of sync with evolution theory ... except for the order of fossils that evolution-believers wish to see for vertebrates transitioning from water to land. But the Flood of Noah buried those fossils in water-to-land order anyway, without evolution having anything to do with it. Geology shows creation theory is right on all points of animal history. Geology shows evolution theory is wrong on all but one. Even on that one point, the suggested link-fossils are all in the same sediment layer (Devonian), and are disqualified by features that show that they are clearly not the missing-links needed for evolution to be true.
