Yorkshire coast ammonites

Thanks AndyS. Duly updated.

Delighted to see from your blog that you have spent 450 days on holiday in Yorkshire!

Hajar,

Yes - I thoroughly enjoyed every one of them !
It must have been more though - I was only counting the collecting days ! Allthough, big big thankyou to my wife, she lets me collect most days (interspersed with the odd shopping trip, that´s where I pay, most literally...)

All the best,
AndyS

Excellent! Did you ever come across jaws and radulae in place (http://palaeontology.palass-pubs.org/pdf/Vol 22/Pages 265-271.pdf )?

The link seems to be broken.

Link should be fixed, the )? was being copied as part of the URL.

I loved the "the missing parts ... fell victims to the saw before they were detected" part

 

[Terri]

Thank you D!

 

[Hajar]

My apologies. Thanks Terri & D.

Here's a pretty 11 cm Harpoceras from that coast.

This one reminds me of the baleen of a baleen whale where the folds allow for changes, in this case to circle and in the whales case to expand and contract. I wonder what the similarity in timing is for convergence (if any )

Beautiful, the Yorkshire Coast is now on my list of the many places I would like to visit (to fossil hunt).

Hajar,
I´ve only seen one with a potential jaw in place as described in the paper you quoted,
but it could have been a bivalve as well...

Not quite jaw & radula but...
I´ve found what looks like a Peronoceras aptych "at home" during prep work one one of my finds from this summer.



The complete story is in my latest blog post at andysfossils.com
