Yaxley Jurassic Clay Id Help Please

Recommended Posts

Hi there guys, it's been a long time! I wish I could contribute more but since one is not allowed to collect fossils here in South Africa, I only get the opportunity abroad. The last time was 2011 in Angola.

I had another opportunity to get my hands dirty recently on a trip to England to visit family. I had literally two hours at Yaxley and managed to scratch up a few specimens.

I apologise in advance for the poor quality of specimen, photo and cleaning. I didnt want to damage the pieces as they are quite fragile, but I did do my best to get most of the clay off.

I have very little to no idea of what I've found... I would appreciate any class / genus / species info that I can go and research.

I would invest more time into self study and a better camera if I had some accessible fossils nearby

The first three photos are of the same piece - a pyritized something...I have no idea what it could be part of... any ideas?

4th pic of some big shells I found

Ammonites, I was happy to get some at least. Is it possible to identify them down to genus / species level? I was really surprised to see some still had a sheen of mother of pearl on them, while others were slightly pyritized. The middle of the four on the left - it looks slightly more nautiloid (is there even a distinction?)

I believe the sixth photo shows belemnites

11112442_10206253607155061_9134205297282

these larger fragments may also be?

...and these?

I dont know if this is just matrix at the base of one of the above or something else entirely

these three were clearly different to anything else I found

10256684_10206253616075284_6822810579565

I believe the bits on the left are worm related... the piece on the right has quite a symmetrical three sided base, I'm wondering if it isnt a badly damaged shark tooth?

11713853_10206253622275439_6018201162376

the smallest find of the day. Very fragile, it had a second protrusion on the caudal end that fell of when I picked it up. Could this be something like a polychaete worm?

This next piece was shining up at me from shallow water. There seem to be various pieces of stuff in there

11703239_10206253631035658_9000579234957

I dont know if this is necessarily a fossil or from anything living, but I did find a few bits of this black stuff... It crumbled pretty quickly

and then lastly this bit of shell

1799201_10206253632355691_90655883874762

I'm sure this is all pretty basic stuff, but I got really excited finding each piece!! I wish I could do this every day :)

Thanks in advance for any response

cheers

The limit is relative to each post. ;) You could have added more images in your second post, above; or in your third post that will probably follow. :)

Thanks JohnJ :)

I loaded the pics onto facebook and referenced them from there

I've completed my post, thanks for your patience

6, 7, and 8 are indeed all belemnites - those are also belemnites in your matrix fossils. Unsure about the others but nice finds!

thanks frankh8147 & ckmerlin

I was really impressed with the yield at the site... if that's what I could find in 2 unprepared hours, I'd love to see what the locals have found!

First three pictures aren't fossil, they're mineral, next comes Gryphea, then lots of partial belemnites and ammonites, haven't got access to my keys for looking them up at the moment

"This next piece was shining up at me from shallow water. There seem to be various pieces of stuff in there"

I think they are crinoid stems.

Edit : I agree with Chris about Genicularia vertebralis,good ID. http://www.thefossilforum.com/index.php?/gallery/image/26531-annelid-genicularia-vertebralis/

Nice findings :) ! Some images prevent us a clear analysis of your fossils...However the fourth image seem a Gryphaea and the sixth, seventh, eighth and eleventh are clearly belemnites.All amonites belong to the order Amonitida.The last fossil could be a Brachiopod name's Rynchonella.
