thisfossilguy2006 Posted May 27, 2018 Share Posted May 27, 2018 I recently acquired a large collection of fossils and I need help identifying them. #1 This was found along Charmouth beach in the pebbles so I don't know the geological age. #2 These are from Petersfield from a stream. Again, no idea of the age of it. #3 and #4 I don't know where these were found but I'm pretty sure they belonged to some sort of mammal. Link to comment Share on other sites More sharing options...
Monica Posted May 27, 2018 Share Posted May 27, 2018 #1 looks like it could be graptolites, but perhaps it could also be part of a bivalve (i.e. the hinge)? 1 Link to comment Share on other sites More sharing options...

Thanks for the suggestions. I'll see what other ideas people put forward. Link to comment Share on other sites More sharing options...
Fossildude19 Posted May 27, 2018 Share Posted May 27, 2018 # 1 is a cross section of Crinoid stem. - 4 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Fossildude19 Posted May 27, 2018 Share Posted May 27, 2018 Can we get more pictures of the other sides of each item, as well as end views on the bones (both ends, please.) ?

Max-fossils Posted May 27, 2018 Share Posted May 27, 2018 I agree with Tim that crinoid stem cross-section seems to be the best match for #1. Not seeing any bivalve, and the triangles seem a little too triangular for graptolites. Plus Charmouth has many crinoids, and I haven't heard of any graptolites being found in the rocks there. If the rock was found in Charmouth then there is about a 90% chance that this rock is from the Blue Lias of the early Jurassic, some 195 million years old. #2 does seem to contain some kind of fossil, but I can't tell what. More (and better) pictures will be needed. #3 is definitely some kind of mammal bone. Perhaps a rib piece but I'm not sure. The chances are extremely slim that the bone can be assigned to a specific species, because it is only a fragment. It's possible that it's modern and not a fossil. To find that out, you can do a flame test: take a lighter/match and softly burn the bone piece. If it starts to stink badly, then it means that there is still collagen in the bone, meaning the bone is modern. If nothing happens, then it's probably a fossil bone piece. Most likely Pleistocene of age in that case. Hopefully this helps! Max 3 Max Derème "I feel an echo of the lightning each time I find a fossil.

Monica Posted May 27, 2018 Share Posted May 27, 2018 Agreed - longitudinal section through a crinoid stem is the best ID for #1. Link to comment Share on other sites More sharing options...
thisfossilguy2006 Posted May 27, 2018 Author Share Posted May 27, 2018 The clearest picture I could get of #2 is this one: The ends of #3: The other side of #3: The end of #4 (the other end looks exactly the same): The other side of #4: I hope this helps!

FossilSniper Posted May 27, 2018 Share Posted May 27, 2018 Is there a back to #2? Or is it covered by matrix...? If there is an available back view, it may help with the ID. Link to comment Share on other sites More sharing options...

If there is an available back view, it may help with the ID. It is just flint on the back. The only part you can see is shown in the picture.

FossilSniper Posted May 27, 2018 Share Posted May 27, 2018 If there was something on the back, I would have guessed it to be a very weathered bivalve. I honestly don't know what #2 is, and I'd wait until someone from the UK can tune in. 1 Link to comment Share on other sites More sharing options...
