The other day I took a walk down to a local fossil hunting spot here in Dorset that I’d not been to before (it’s called Chapmans Pool – not sure why, because it’s a sea cove).

Within the dark grey shale cliff there were lots of white, flattened ammonites seen in vertical section. Notice how they all lie flat along the bedding plane (they were all like this within the strata, I haven’t just selected a favourable spot).

Where blocks of harder shale had fallen out on to the beach the horizontal surface of the shale bed was exposed with the ammonites again lying flat.
The mainstream interpretation is that the shale was laid down as mud in an offshore environment during the Upper Jurassic. When ammonites died they were most likely to fall flat on the sea floor, just as you would expect. The calcareous shells persisted and were buried in sediment over time as generations of ammonites lived and died over the millennia.
I try to think about this from a flood geology perspective and it doesn’t work because why would they all be lying flat ? If the ammonites all got deposited within a mud flow they should all lie at random angles. In the unlikely event during this global catastrophe there was a local area of water still enough for sediment particles to fall out of suspension then the heavier ammonites would fall to the bottom first in a dense layer to be deeply buried above by pure mud.
This is just one small but simple observation that I think strongly favours a mainstream interpretation. I imagine there will be some here who would disagree ? If so, why ?
