Hi Daniel
With the tide coming in it seems that you did not pick the best time to visit the Holderness for fossils.
To the north towards Hornsea and between the groins at Mappleton you would have got some collecting time in-in the morning but would have also been pushed off the beach in this area after dinner whilst to the south past the last groin were the sea has eroded back into the cliff, land and beach - as you said was underwater when you arrived.
Pity about the dino foot print, I mentioned to fussy fossiler about taking a course fishing trolly with you, it can be left in the car until needed. 
Get one with pnewmatic, wide wheels because thin wheels sink into the sand and make recovery of your specimen almost impossible.
I once found two dino prints near each other one day, I also left the biggest because it was very heavy but now I look back it was probably the best one.
Was your dead fish a Lesser Spotted Dog fish? loads around at this time of year.
Acid prep? sometimes the matrix contains too much iron pyrites to prep and acid will not touch it but I think your specimen looks good as it is.
Nice finds.

Hi. Thanks for the reply. I think the fish was a lesser spotted dog fish. I removed some of the hard pyrite surrounding the nodule and put the nodule in vinegar this morning. It seems to be working but very slowly; I think it will be a few weeks before its done.



Next week I'm going to Skegness; mainly for carp fishing but also I go fossil hunting. I found my first ammonite there, and the tides are very good so hopefully I'll find something. I'll post my finds in another topic.


Thanks,



Daniel

An image of Mappleton with the tide going down towards Hornsea and Bridlington in the North.
Our bit of coast line from Bridlington to Spurn Point is supposed to be one of the quickest eroding areas of land in the world.
Basically when the cliff cannot support its weight because of water content it rotationaly slumps onto the beach and is dissolved into the North Sea.
You can see on this image suspended particulates of Boulder Clay (brown) in the blue sea as the tide is going down to the north.
During the winter months the muddy sea can sometimes extend out of sight.

Now then Dave how are you doing?
You have found a Septarian nodule, it has been formed by water containing minerals soaking through the boulder and leaving behind a deposit/build up of minerals in cracks throughout the boulder.
Nice find.

Hi. I agree with tabfish. It would look good if polished, though it can take quite a while.

Hi. I prepped this partial ammonite today. Is it Arnioceras semicostatum?


Thanks,

Hi. Recently I have been prepping two of the fossils found from our last visit to Mappleton; my Dads Dac and my fish bone. I prepared most of the Dac using a micro chisel, but I'm finishing it off with an etcher. Though the acid was working for the fish bone, it was very slow so I decided to use my etcher. I have spent a few hours on it (the etcher only removes very small pieces of rock) and it looks to me to be Gyrosteus sp, though I may be wrong.


Neither of them are quite finished, but here are some pictures.



Thanks,

Hi. I finished prepping the bone today. It turned out much better than I thought; I have little experience in prepping and I only use a cheap etcher, so I wasn't expecting it to look very good. I assume it is part of a Gyrosteus fin bone. Does everyone agree its a Gyrosteus fin bone or does anyone think its something different?


Thanks,

Hi. I was looking on the internet today at early Jurassic ammonites and I saw an ammonite (Echioceras), which looks like the largest ammonite on my multiblock. Can anyone confirm its Echioceras ?


Thanks,

Daniel

Hi. Here are some more pictures of the ammonite.

Not an Echi Daniel and hard to say it's a Arnioceras semicostatum but more like a transitional specimen.
Looked at the ribs sloping backwards but it is like a Arnioceras kridoides with a more inflated whorle.
Hard to tell but a very nice find.

Hi. Thanks for the reply. I'll label it as Arnioceras sp. What does backward sloping ribs mean?

Thanks,

 Hi Daniel
The ribs don't face forward towards the living chamber / mouth border, but slope backwards towards the centre of the ammonite.

Reckon Harry's got it, I'd go with Arni kridioides, especially on the keel. Nice specimen, and prepping.

Hi

Perhaps when you post your photo you could start a new post as this is 2 yrs old.
