I doubt that the bones were as accessable as you are indicating here. The first photo shows evidence of painstaking chipping away to reveal the fossil bone, which probably took hours. In the third photo one can see quite a bit of material has been excavated. Disarticulated bones are a common occurence when creatures die, and they can become broken before or after burial.
The picture seems to speak for itself-- the dino was buried in diggable material at maybe 3 or 4 feet. Why wouldn't uniform sedimentation be everywhere? There would have been continual weathering, wind and flash floods. What would have prevented sedimentation for a continuous 65m?
I interpreted your post to be saying that the bones were basically just lying on the surface. I’m not sure how easy it is to dig the material, but 3 to 4 feet below the surface is quite a depth even if what was excavated is soft. It is to be expected in the current badland topography that the clays in shales have softened through weathering. That is the nature of bentonite.
I really don’t know what you are saying here about uniform sedimentation unless you are saying that sedimentation of all geologic units is always the same at all places. At any point in geologic time some parts of the earth’s surface are in depositional basins where sedimentation takes place whereas others are emergent areas that are subject to erosion. Through time this can reverse with the opposite is true for the respective areas. This place is currently emergent, with erosion taking place. The top unit is Paleocene, so no sediments from epochs younger than that are present. That speaks strongly against having continuous sedimentation from the boundary of the Cretaceous to the present.
I think a "continuous" layer at the boundary of the Creataceous and
Tertiary would only be expected in some sort of creationist flood model.
Why? Catastrophic water suspending various sediments in different areas, over different topologies, and already laid sediments as the water got higher, and at different episodes over a year is going to cause a "layer?" Layers seems to be more accurate.
OK, if you want “layers” versus a “layer” in your creationist model go ahead and postulate them. That was not my point, which was that world-wide deposition at the boundary of the Cretaceous and Tertiary in a continuous layer found upon all the surface area of the globe would not be found in a standard geologic model but could only be possible in a creationist model with flood waters covering the entire planet up to a level above the highest mountaintops.
Standard geologic models would not state that 65 million years of sedimentation has been eroded away. There would be periods of non-depostion involved.
Using that premise, in the picture I submitted there must have been more periods of non-depositition in the fossil area than the hill. I'm trying to imagine in a slow process, why one area so close would receive sediment, and the other wouldn't. It's not a loose sand dune. It would seem to be a much more compact sediment like clay, wouldn't you agree?
On the other hand, in turbulent water and soft sediments, I can imagine both sedimentation and erosion going on at the same time in a confined area.
I don’t see how it is logical to say that my comment would entail more non-deposition in the fossil area below than in the hill. The hill is most likely fossil-bearing as well, except no dinosaurs are found within it. That in itself presents a huge challenge to your explanation of the sediemnts above and below being basically contemporaneous.
The present topography is not really the result of the original deposition and then non-deposition but from relatively modern erosive processes that have carved the landscape after the fossil-bearing Cretaceous strata and those deposited above them were uplifted. What remains is the result after the rocks in the overburden have been removed with time. The area in the foreground and the hill both received sediment (at different times) and that is why there are rocks present in both places.
And no, I don’t think the hill is clearly not a loose sand dune for I can see the bedding surfaces clearly and they do not show cross-bedding I think it is made up of shale, but that is because of the way it has eroded. I can’t tell how “compact” the sediment might be from the photo.
Yes, it is possible that both erosion and deposition might have taken place in a relatively small part of the area. However, the sediments present records sedimentation (a depositional event) and any erosion taking place at the same time basically removed earlier deposited sediments.
The hill in the background appears to clearly be stratified rock, whether it is relatively soft of not. It forms a scarp, which indicates it is not just soft clay. The vegetation is probably growing in the clays or soils that are the products of erosion and the effect of the bedding surfaces can be seen in its distribution.
1) Define rock please. I define rock as something you can't dig in, you have to break through it. I realize some rock is softer than others, but there is a degree of hardness and/ or brittleness to rock.
I used to dig in my younger years. I used to hit rocks. They stop your shovel and you dig around them.
2) Soil would come from decay of vegatation, so if it's rock underneath, then the soil build up is not much for 65 million years. Bedding planes form in current and from dessication as was shown in Julienne's paper.
Rock is a consolidated aggregate of minerals. A rock has at least some mechanical strength. I think what is seen in the hill would be much too hard for you to shovel into except where weathering has softened it, possibly in the outside inches. Soil would contain some organic material from the decay of vegetation.
Your lack of acceptance of tectonic uplift is the base cause of your erroneous conclusion here. But that is the weakness of being constrained by a model that creates sedimentary layers and then supposes that what is left after the flood event is basically the present topography we see today. Once again, the present surface where soils might form has not been exposed for millions of years. The products of erosion have been carried away from the hill for some time leaving relatively little soil or broken up clays lying in the surface. We are looking at a surface that is much, much younger than 65 million years but essentially much, much older than 4,000 years taken in a general sense.
Then there is that pesky coal bed that cannot fit into your creationist model, and least not logically.
I have not seen Julien’s paper, and I do not know what it says about desiccation, or how desiccation fits into any model you accept, since the sediments shown in the flume experiment in the video were all underwater and water-saturated. Yes, bedding planes can be the result of current action. However, the sediments here are do not appear to be sand as shown in the flume experiment in the video and would not have formed in the same way. They would not be from the same upper flow regime.
This looks like "layer cake" geology with clear stratigraphic units. Using the geologic principles of Superposition and Faunal Succession, your concept of them all being deposited at roughly the same time does not work. The fossil content in the Tertiary unit will be very different than in the Cretaceous rocks below showing a lack of them being contemporaneous.
Though we don't agree on Berthault, I know what I saw in the log flume in water current. Mckee 1965 saw bedding planes formed in Bijou Creek after a flood. If multiple strata could not be formed in upper regime water current(as I believe McKee reports), then creationists would be "up a creek." But it figures that this would be found, as I believe that modern old earth geology is founded on wrong assumptions.
We do not disagree that water currents create bedding surfaces. All geologists see evidence for this. We see them form in lower flow regimes and in places of relatively little current. This has been observed in laboratory experiments and in actual deposition taking place around the globe. They were noted in high flow regimes long before Berthault made any claims. What makes creationists be up a creek is drawing the conclusion that all strata are formed in high flow regimes as Berthault has done, and the video reiterates.
