Guy Macdonald Posted July 25, 2017 Share Posted July 25, 2017 These fossils were found by me in a woodland by my house, the area it was found in was rich in clay and moss, the first fossil intrigued me most as It definetly looks like a very faded ammonite, can clay yield good fossils though? and are these even fossils, thanks. And the final one. Link to comment Share on other sites More sharing options...
Fossildude19 Posted July 25, 2017 Share Posted July 25, 2017 What are the sizes, on these? 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

The assumed ammonite is fairly small, on the average hand if you were to put your middle finger and your thumb together to form a circle it would be about that size, this would only apply to male hands though really that are above average. The other two span out to the length of your average paperback book. Sorry I'm trying to make it easy by comparing it to something as I have no way to measure them at the current time.

fossiling Posted July 25, 2017 Share Posted July 25, 2017 Yes, size is very helpful in identification. PS. Don't use coins, as people from other countries may not be able to view the size. 2 Keep looking! They're everywhere! Link to comment Share on other sites More sharing options...

At a guess by looking the ammonite is about 7-10cm across, with the other two being around 15-25cm across. Link to comment Share on other sites More sharing options...

Miocene_Mason Posted July 25, 2017 Share Posted July 25, 2017 I think the first one is an ammonite, clay can be formed from solid rock that has been broken down, fossils in harder minerals will survive this and be deposited in the clay. I can't really be sure about the Second one, doesn't look fossil to me though. The last one looks to have a few pieces of shell material scattered throughout it, maybe a belemnite. 1 “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...
JohnBrewer Posted July 25, 2017 Share Posted July 25, 2017 'On top of your average sized iPad mini' Average size? Best use a ruler @Guy Macdonald can you be more specific with where you found them so we can determine the era? If you don't want to reveal the place you could use something like the 'fossil explorer' app. With your potential ammo you could try scanning it rather than photographing it and include a ruler. This is often a better method rather than a camera. John Map of UK fossil sites Link to comment Share on other sites More sharing options...

These three were found in a small woodland 2-3miles from me, the particular patch of ground I pulled these from was heavy in clay, all were covered in moss and clay. The small ammonite is 9cm and the other one is at 16cm, those aren't 2 separate fossils it's double sided lol. The area around the fossils was also heavy in clay, and just general mud everywhere else. Link to comment Share on other sites More sharing options...

I'd try using a geologic map, and if you have the patients, try cleaning up the Ammonite with a scribe (if you have one). If I'm correct, should be jurrasic in North Cave, can you tell which one your in? Here's a map I found online. “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...
Taogan Posted July 25, 2017 Share Posted July 25, 2017 The potential ammonite looks circular to me, as in a ring shape. Most ammonites are spiral. Could it be a coral? It needs cleaning a bit. Link to comment Share on other sites More sharing options...
JohnBrewer Posted July 25, 2017 Share Posted July 25, 2017 Jurassic is good for ammos. When you said north cave I didn't realise it was a place! I think I see suture marks on the small one, try gently washing it maybe with a gentle scrub with a toothbrush and then scan. 2 minutes ago, Taogan said: The potential ammonite looks circular to me, as in a ring shape.

Judging from this I appear to be sitting pretty right on lias group - Mudstone, siltstone, lime stone and sandstone (brownish colour) Any advice on how to clean this would be appreciated, not sure what a scribe is still all so new to this looking to learn as I go on though Link to comment Share on other sites More sharing options...
JohnBrewer Posted July 25, 2017 Share Posted July 25, 2017 Suture lines at light coloured area 9 o'clock. Does look to round for ammo so I'm 75% going for rugosa. 1 minute ago, Guy Macdonald said: Judging from this I appear to be sitting pretty right on lias group - Mudstone, siltstone, lime stone and sandstone (brownish colour) Any advice on how to clean this would be appreciated, not sure what a scribe is still all so new to this looking to learn as I go on though Toothbrush and water gently. 1 John Map of UK fossil sites Link to comment Share on other sites More sharing options...

No problem I can do that, hopefully this will bring it back a bit looks very faded Just now, Taogan said: North Cave is on the Grey Chalk so not Jurassic and these were surface deposits, could be anything from anywhere, I would guess rugose coral from a glacial deposit Aye it's a place haha just a very small village, I often go to the beach fossil hunting but I just though I'd give it a go I already knew the woodlands well glad I found some cool stuff.
