Ammonites and gastropods.

[Pleuromya]

Hello, sorry to be a pain with all these IDs. I thought itd be easier if I just put all of them in one post. All were found in Northamptonshire, UK. Which is mostly Jurassic in age.

Sorry there's no scale, I couldn't find my ruler anywhere. I'll have to upload more images below this. Its been quite some time since I've found ammonites. The land had just been rotavated, and aside from the ammonites, I found some Bivalves, and two golf balls buried.

Thanks.

 

These are the first two ammonites, I tried to ID them, but they are incomplete, so it was a difficulty, the closest I think it looks like is Harpoceras. Each are about two centimetres (about 0.8 inches). I saw a neighbour had a very similar rock with two larger ammonites on them that was being used to hold a fence down.

Here are a few larger bits/imprints of ammonites. The first bit is largest, at about 8cm.

A few bits in ironstone. These are much smaller, about one centimetre each.

These are the gastropods. Each is tiny, at about 4mm. I thought I had found a match, but infortunately, that wad found in the Silurian of Estonia, so I have no clue what these could be.

And lastly these I found, they look polished. They are each about 1.5cm.

I just noticed the quality of some of the pictures aren't great, I'll swap a few pictures for better ones.
