Somerset Coast Coroniceras


Terry Dactyll

Recommended Posts

I had a bit of a trip out collecting on the coast yesterday afternoon and I dropped on (tripped over) a reasonable nodule that had varying degrees of preservation in it from very powdery weak ammonite shapes to half decent specimens as I worked through it with a bricky's hammer... I ended up with 3 bits that should come out ok when prepped and obviously pretty rare for this coast... A friend helped me with the ID for them and we think they could be Coroniceras sp. aff. rotator a very early species of Coroniceras...They are all around 1 1/2" across....

Very nice finds, Steve!!! :wub:

Based on your previous prep works, I imagine a very impressive final result... :rolleyes:

Though, with so much stuff in pending, the question is when this prep could take place... :P:)

Thomas.... Thanks... Lucky find, tripped over them as you do!...They come out ok considering the hardness of the matrix and the variable quality of preservation...Coroniceras sp. aff. rotator ...(biggest 2 1/2")... North Somerset Coast...Lower Sinemurian, Bucklandi Zone, upper conybeari Subzone

Steve,

Awesome work, as usual! :wub:

These are aesthetically pleasing looking plates.

Any ideas on what the dark colored bivalve is?

Thanks for sharing these,... would love to be able to collect such beauties.

Cheers Guys...

Roger...Great practice to get your eye in...

Tim...The bivalve... Maybe Protocardia truncata... I'm not 100 % sure as I have limited reference material on bivalvia...

That's exactly the wonderful final result what I was expecting for!!! :wub:

What I didn't expect was their prep to finish that fast, even in the lead of the queue :o

High quality at a high speed isn't a common phenomenon at all... :):fistbump:

Astron... Thanks.... I reckon I need to speed up to catch up with you ;)

Here's a nice specimen... I wasnt really expecting to find one of these on the north Somerset Coast although I'd hoped... It has slightly different preservation than most of the other material Ive dropped on as the matrix is softer and more fibrous and quite thin calcite although the colour of the calcite seems comparable... It still stuck to the calcite shell like glue though with every mm needing attention to remove it....

Stunning finds and prep!

I'm only over the bridge, should pop down there one weekend with the kids and see what turns up, they are quite interested in fossil collecting now.

Thanks.... Yes go take a look... Theres signs of fossils all the way from Blue anchor to Hinkley point but the 'good stuff ' takes some rooting out (and luck)...You just never know what you will trip over...

  • 3 years later...

Its been 4 years since I dropped on my first Somerset Paracoroniceras charlsei so you can see they aint to common... You got to take into account most of the material you do find will be partial fossils and even sometimes complete ones, the preservation varies with many duds so Ive been very lucky....This is my current shell I'm working on....

I was glad to get this back to the car...a heavy old chunk...

post-1630-0-26263000-1455046485_thumb.jpg

You can see the tell tale nodes preserved.... These disappear as the shell gets bigger in diameter....

post-1630-0-83618500-1455046534_thumb.jpg

Proving the shell is worth the time by prepping a slice out....

post-1630-0-37456000-1455046623_thumb.jpg

Going in further for the 3rd whorl preservation....

post-1630-0-55168000-1455048107_thumb.jpg

Starting to uncover more of the shell rib by rib and opening and straightening the mouth border.....

post-1630-0-61908200-1455046652_thumb.jpg

Doing some roughing out chisel work on the matrix....

post-1630-0-05645800-1455046713_thumb.jpg

I'll keep this thread updated as I get closer to finishing this shell....I'm just doing a couple of hours heere and there on it during the evenings....

Hi Roger.... Thanks for your interest....

I have done a little more on the shell including working on the matrix and cutting a base on the rock.... I need to take some weight off it as it still weighs a tonne... You can clearly see the distinctive nodes of Paracoroniceras charlsei... Its looking a little muddy as I am in the process of getting the fine layer of rock off with wet and dry... it was looking a lovely colour of reddy brown before it dried leaving the mud layer on... It will all come off with the hosepipe and scrubbing brush later....

great prepping job Terry , looking forward to the finshed part when the last layer of mud is washed of.

Do you have a picture where we can see the keel?
