Help Identifying Fossils From Weymouth, Dorset

[Aurelius]

Hi there,

My girlfriend and I spent a fun hour at Weymouth, searching the clay for a Cardioceras ammonite and anything else we might be able to find. We got several complete giant oysters, but found some other bits, that, being newbies, we can't fully identify.

Any help would be appreciated

Ammonite fragment - Cardioceras? Size around 40mm.

Bivalve of some kind?

Ditto for these...

...and these!

This block contains lots of shelly bits, but I'm particularly curious about the bit on the right (there's an identical bit on the reverse) and several bits that look like teeth, but I suspect this is my Over Optimism Syndrome kicking in.

Finally, I had a go at some of the red nodules that can be found in the clay, to try and find some ammonites. This one revealed a white shelly substance when I knocked a bit off, but I've no idea what it might be, or how to extract it well. Any ideas would be most welcome. My air pen should be here in a few days!!

Picture 4: I suggest Modiolus bipartitus

Picture 5: Trigonia (Myophorella) sp., possibly Myophorella clavellata

Picture 7 (in the center of the grey stone): my suggestion is a small or juvenile Lopha sp.

Thanks, those suggestions look pretty good to me! Really appreciate your response, gives me a good starting point for doing some reading.

If anyone can identify the ammonite, please let me know

agree with araucaria very similar faunae than in "les vaches noires"

I would suggest lopha marshii for the lopha one

link to "les vache noires" faunae

u will see all your critters there kinda.

I dont know anything bout England geology but is weymouth from oxfordian age ?

I think you've got it, Lopha Marshii looks like a convincing candidate!

You're also quite right, there's a large landslip of Oxfordian clay at this location, which is where all of this came from. Thanks for the link!
