Hi all
I was in Burton Bradstock at the end of July, and found these two ammonites, among others, in fallen blocks on the beach.
Could anyone give me an ID for them?
Thanks a lot

1. Parkinsonia ...?

2. Brasilia? Ludwigia? ... ?

Your first ID seems correct to me...Parkinsonia.  You don't show the venter in your photos - presumably it has a smooth depression running all around.  This would more or less clinch the classification.

For the second, you could be right on this too, assuming that it has the characteristic Brasilia keel.

Handsome ammonites, whatever they are.

Thank you for your reply.
The photos were taken on the spot, as found, but I'll post pictures of the venter of both ammos, so to maybe manage to identify the species
Cheers

Hi all
Maybe these pictures will help to find out the species (haven't prepped the ammos yet)

Perfect photos...just what I expected, the smooth depression on the venter of Parkinsonia and the more acute keel on what you and I both think is a Brasilia.  I expect you know the stratigraphy at this site - these ammonites will have tumbled to the beach from the layer of "Inferior Oolite" (Bajocian) at the cliff top,   Isn't there another Brasilia buried in the same block?

Yes, there is - and a couple on the underside of the block as well 😎
I'll be tidying them up in the weekend, hopefully, and will post pictures when done
Cheers
