Can Flood Geology Explain the Fossil Record?
1. Precambrian: Pre-Flood
2. Cambrian: Heavy rain ...; Erosion, deposition of ocean sediments; formation of Precam/Cam. unconformity
3. Ordovician: Rising water; coarse to fine grading of sediments
4. Silurian: High water; deposition of thick shale & limestone
5. Devonian: Tidal & wave action; cyclothems; rhythmic deposition
6. MS-PA: Water covers all land; formation of coal; lowland forest burial
7. Permian: Rain stops, wind blows; cross-bedded sandstones
8. Triassic: Mountains rise; moving continents
9. Jurassic: Waters start to recede; Mountain-building
10. Cretaceous: Major erosion of new mountains; guyots
11. Paleocene: Fossilization of reptiles; coal formation; upland forest burial
12. Eocene-Oligocene: Water continues to recede; fossilization of mammals; continental margin sediment; less dense strata
13. Miocene: Major volcanism
14. Pliocene: Localized sediments & valley fills
15. Pleistocene: Post-Flood erosion; glaciation
16. Recent:
_... the Palaeozoic cannot represent submarine deposition and the Permo-Mesozoic the transgression of pre-Flood seas over the land because the Palaeozoic itself represents that transgression — the marine deposits of that era lie over continental deposits, not Precambrian ocean floors.
_ The Lower Cambrian quartzite above the unconformity also shows evidence of rapid deposition.60 In Scotland there are two unconformities below the Cambrian. The earlier separates the Lewisian gneiss from the overlying Stoer and Torridon Groups; the later unconformity comes between these and the Cambrian quartzite. In Arizona, similarly, there is an unconformity between the Vishnu Schist and the overlying Unkar and Chuar Groups (consisting of limestone, shale, sandstone and conglomerate) and a second between these and the Tapeats Sandstone ('The Great Unconformity').61 The two regions bear close comparison. The Torridonian Sandstone testifies, in its 'fluid evulsion structures', to sediment dumping on a massive scale, just as do similar features in the Unkar Group. These deposits above the metamorphosed rocks of the Precambrian — regularly thousands of metres thick — constitute the rocks which were eroded when the fountains of the deep broke open. The horizontal surface of trans-gression at the later unconformity marks the violent incoming of the sea some weeks later. Ager remarks that an unfossiliferous quartzite lying conformably below fossiliferous Lower Cambrian and unconformably above a great variety of Precambrian rocks — exactly the situation in Scotland — occurs 'very commonly around the world'. Indeed, 'It is not only the quartzite, but the whole deepening succession that tends to turn up almost everywhere, i.e. a basal conglomerate, followed by the orthoquartzite, followed by glauconitic sandstones, followed by marine shales and thin limestones. '62 The lateral persistence of this succession is striking enough. What is yet more striking is that it represents an overall grading of particle sizes, from very coarse at the bottom to very fine at the top. This is the sort of 'upward-fining' pattern which one often finds in a series of beds, such as a cyclothem. In other words, the whole succession has the unity characteristic of a single episode of erosion and deposition, during which material is eroded by fast-moving currents, held in suspension, and then water-sorted as current velocity wanes — as a result, for example, of the water becoming deeper. Commonly a coarse lithology prevails at the bottom of the Cambrian succession (conglomerates and sandstones), a fine lithology at the top (limestone and dolomite), while shales, silts and mudstones occur in-between.63  Widespread carbonate deposition continues until the end of the Lower Ordovician, after which a surface of erosion marks an unconformity over much of North America.64 Marking the end of one continuous sequence, this would seem to represent, so far as North America is concerned, the virtual completion of transgression over the continent, followed by a steep increase in bioturbation as current strength and sedimentation rates decreased.65 
_Except over the Transcontinental Arch, Cambrian rocks are found throughout the North American interior. Those regions where they are absent were either source areas for deposition elsewhere or eroded subsequently; there is no evidence of any pristine topography. By the Upper Ordovician the process was complete: the sea had spread eastwards and westwards across most, probably all,74 of the continent — after the entire Precambrian land surface had been broken up, inundated and redeposited. If we adopt Austin's own estimate of the speed of transgression, upwards of two metres per second, 500 miles would have been covered in 4-5 days. If we halve this rate in order to take account of higher elevations inland, the whole continent could have been transgressed within four weeks. Cambrian rocks, often with an unconformity at their base, are of worldwide occurrence, making it possible that by the Upper Ordovician every part of the earth was deluged. 
_ ...  there is no trace of a vegetated terrestrial surface at that time anywhere. The spores and woody plant material recovered from Cambrian strata76"79 occur in sedimentary deposits and are not therefore in their original locations. ...  it seems clear that the Upper Precambrian to Lower Ordovician transgression must be placed within the first 150 days of the Genesis record. Accordingly, all Cambrian deposits must be Flood deposits, and wherever they are found, the land must be already under water. At that point the possibility of pristine land surfaces comes to an end, until a new surface emerges out of the Flood. ... In reality, although extensive regions may once have been underwater shelves, in general the continents of today are undoubtedly fragments of the supercontinent before the Flood. It follows, therefore, that the Lower Palaeozoic marine animals fossilised in, say, Iowa, hundreds of miles inland from the pre-Flood shore, must have been transported enormous distances (Figure 5). Because the whole Earth was under water well before the end of the Lower Palaeozoic, it is impossible to explain assemblages after the Lower Palaeozoic — including terrestrial assemblages — as originating from nearby provinces which had not yet been inundated.
_Did Animals Escape to Higher Ground? ... The Cambrian, Ordovician, Silurian and Devonian deposits exposed on the Earth today are marine and igneous deposits overlying a Precambrian basement, and that basement is the scoured remains of the primeval supercontinent. Strata at the pre-Flood boundary do not represent the surfaces of pre-Flood sea bottoms, while none of today's ocean floors are older than Mesozoic. The Atlantic Ocean, for instance, originated in the Jurassic, when 'Pangaea' rifted apart and new seafloor spread out from the Mid-Atlantic Ridge.94 ... Terrestrial animals are totally absent from strata of the Lower Palaeozoic because they were obliterated: 'In seven days I will send rain upon the earth . . . and every living thing that I have made I will blot out from the face of the ground.' (Genesis 7:4)
_Again, it is important to keep in mind the violence of events during the first six weeks of the Flood. In still waters the corpses of most terrestrial animals will float on the surface, and a few will sink to the bottom. In turbulent waters bodies which are heavier than water take longer to sink, and in the meantime are subject to processes which rapidly reduce them to nothing: physical dismemberment through continual buffeting, consumption by scavengers and predators (sharks, marine reptiles, carnivorous fish), abrasion and pulverisation in churning sediments, chemical and bacterial decomposition. In the conditions of the first 40 days — beginning with the stripping of the original land surface to depths of thousands of metres — it is difficult to imagine that any remains of land animals could have survived in recognizable form. With its widespread volcanism and metamorphism, the Upper Precambrian record suggests that land animals were annihilated almost instantly, by processes other than drowning and decay.
_ The advantage of the fishes, which also would have been borne along by the currents, was that they could swim away once the currents slackened and their sediment loads began to settle. It is this circumstance which explains why they scarcely ever appear in Cambrian strata. Fish that were already dead when the currents slackened would tend to have been buried higher up than the invertebrates because of their greater buoyancy. The mass burials of fish which, in the Palaeozoic, occur in Devonian strata were mostly the result of shoals being overwhelmed by epicontinental landslides while they were still alive. Since the conditions most favourable for such burials were shallow waters near emerging land, they are evidence that by the early Devonian the Flood was already waning.98
_...  temporary surfaces were being colonised during the Flood itself, sometimes by creatures that had come into existence during the Flood. It is unlikely to be the case that a broken brachiopod in some Silurian deposit was spawned on a preFlood seafloor and then transported hundreds of miles to its burial place; it might have been spawned on an Ordovician surface which was several months later eroded away, by the same powerful currents that broke its shell.
_There were in fact earlier orogenies, notably the stupendous Caledonian and Variscan orogenies of the Palaeozoic, and these were followed by a period of relative stability during the Triassic, Jurassic and much of the Cretaceous. In the Mesozoic there is no juncture where the whole Earth could be said to have been thenceforth under water. That juncture is to be found only in the Ordovician, whereas as we shall consider presently, dry-land structures occur all through the Mesozoic: subaerially deposited basalts, aeolian red beds, root beds, bird and animal tracks, dinosaur nests and so on. Nor is there a juncture still higher in the Mesozoic where it is possible to claim that the first surfaces began to emerge from the water. That juncture is to be found much earlier at the end of the Silurian.
_The Coal Measures Coal does not occur in the geological column until the Upper Devonian. On northern continents it is most abundant in the Upper Carboniferous, on southern continents (the original Gondwana) it abounds in the Permian, and in both cases the deposits are nearly all located on the then continental margins. A second concentration of coal deposits begins in the Cretaceous and climaxes in the Tertiary (see Figure 3). Since this pattern of distribution is worldwide and can hardly be fortuitous, it requires an explanation.
_The answer, so far as the Permo-Carboniferous is concerned, must be that the measures represent forests of aquatic vegetation — thick platforms of interlocking roots and entangled debris, covering thousands of squares of miles —which were grounded as the waters continued to drain off the land after the Flood year. Successive currents washed the vegetation (including flotsam) into deepening offshore basins, while prograding sediments from the land spread out under the water and thereby anchored the forests.120 ... Soon after a raft of vegetation became anchored in shallow-water sediments, the progressive sinking of the sediments pulled the vegetation below water level in advance of the next prograding cycle. Such processes clearly require time. Within the 800 m thick succession of Pennsylvanian deposits in the Eastern Interior Basin of Illinois and Indiana no less than 51 separate delta advances have been distinguished.121 Together with other evidences of time in the Upper Carboniferous, the cyclothems cannot be satisfactorily explained as the deposits of a few months.
_It is noteworthy that in many places Devonian strata constitute the uppermost rocks of the Appalachian Plateau.125 Elsewhere the record ends with the Lower or Upper Carboniferous, for example in Virginia, Indiana and Tennessee. Far from showing increasing inundation, the Devonian was the time when the Appalachian Mountains began to be uplifted — a process which continued into the Triassic. Drainage off the emergent slopes resulted in the formation of coarse-grained meander-belts below, above and at the same level as the coalfields immediately west of the Appalachians, until the conditions for sedimentary deposition in the area ceased.126 Similar drainage channels have been reported from the British coalfields.127
