Lyme Regis find

[Mycroft]

Hello,

my first post so thanks in advance to all of you who look at novice finds and tell us, with great patience, what we've found.

I found this on the beach between Lyme Regis and Charmouth in what I think is the Black Ven, The stone cleaved easily enough with a butter knife and this was revealed.

The coin in the photos is a UK 5p piece and the fossil measures approx. 15mm X 8mm

 

Thank you

Welcome to the forum!

 

I believe it's the keel of an ammonite. Angulaticeras species are common there and often have that sort of grooved appearance around the venter.

Welcome to TFF!

My first thought is ammonite also.
