Identify my fossil please

Any ideas you brainy lot?

Narrow it down a bit.  Where did you find it.

(Fossils were a big thing in my primary school which was in one of the best places for Silurian fossils , Bringewood is full of them. Finding a trilobite was pretty well the best playground kudos there was short of being good at footy)

ammonite?

That’s Fido Dido’s hair.

Brachiopod, mollusc, amonite… or anything else with a ribbed shell. I think you need to keep hunting for a better specimen before trying to identify it.

Ammonite, possibly Parkinsonia?

As above, location etc might help. Having said that I’ve found all sorts of weird rocks in unexpected places. Glacial erratics, made ground, ballast etc can throw up numerous surprises.

Found on the beach at West Bay near Bridport so Jurassic coast although not the hotspot for fossils like Charmouth.

That location makes it highly likely to be a Jurassic fossil.

Any more pics?

No other pics, it’s flat on the other side.

It is an ammonite. But more than that it is almost impossible to say. Maybe if you could cut the surfave plane to the whorls and polish the surface then you might be able to narrow it down with the shape of the sutures if you were lucky. Otherwise it is just an ammonite sorry.

26″ tyre tracks – late Jurassic, poss early Cretaceous

I don’t think it’s an ammonite as there’s only one whorl.  I’d say an imprint from the edge of a mollusc/bivalve of some flavour.  If it’s in chalk, very likely an Inoceramid, if not, possibly still.

But I can really see where the ammonite is coming from, especially if you remove a bit. What’s the rock?

brachiopod, basically a cockle but dead old

Nobody on here can really tell. There isn’t enough of it.

Nothing to add apart from it’s amazing that something that old could be identified by someone now old. Yeah science, bitch.

Stonasaurus?

Definitely not chalk. Can you take a pic of the lower face / base please?

As Welsh farmer implies, sutures could be diagnostic but as it’s seemingly a mould it’s very unlikely to happen.

As others have said, it’s a fragment of the ‘mould’ of what is most likely an ammonite, their spiral shells are very similar to a nautilus, an extant marine creature very similar an ammonite, although those could grow to enormous size, at least a metre or so across. There are three known species of chambered nautilus, their shells are smooth, whereas the creature we know as ammonites had a ribbed shell:

That is Stewart Stewartson, last seen leaving the 12th Trimester just before the meteor hit. I’m sure the cold case file on this missing person can now be finally closed.

Speaking of fossils and collecting them, this is most definitely NOT the way to go about it!
