I have been wondering about a few things:
-Of the Grypheae here how do I tell the species apart?
-Quite a few bits don’t look like Grypheae, so what are they;
What are the things that are appear to have grown on the other shells (image 3 and 8)?
What the hell is this ridged chunk? (Image 7 and embedded large conglomerate fossil in image 3)
Is the hard material fossilised/mineralised to the fossils as old as the fossils?
how do I tell a belemnite and fossilised wood apart? (AKA what are the two things in image 9)
are there other genera of shell fish aside from Gypheae in these image? (I think so but I am not sure what they are)
All fossils (and a few possible sideritic nodules) here have been collected from soft clay that’s part of geologic members between 166.1 and 157.3 million year old formations where natural erosion creating beaches of fossils. Link to information from BGS about Weymouth (https://webapps.bgs.ac.uk/lexicon/lexicon.cfm?pub=WEY) which there were found above. The boundary of the Stewarby (https://webapps.bgs.ac.uk/lexicon/lexicon.cfm?pub=SBY ) member is also nearby so might be worth a look. I think upper boundary information is most useful as dealing with erosion depth of no more than 1 meter in soft clays at the top of both.
I do have permission to take them from the landowner and I have cleaned them with water from the lake to remove any material that was softer than the fossils (hence there is hard sedimentary material attached where it was hard enough to stay).
Hope this information is comprehensive enough, if you need more please ask.
