Are these IDs correct?


Recommended Posts

 

I just got all these fossils in bulk and was wondering if these IDs are correct.

Sorry for the long post.

The IDs came mixed up so please correct me if  you see any that are wrong. All collected in Yorkshire.

Nice lot of ammonites! :)

I can't notice any obvious mistakes, except it should be Androgynoceras, of course, but i expect you just made a typing error. 

Good Yorkshire ammonite collection.

How odd. 

A double post quoting myself. :headscratch:

Also, I have a few different other fossils like this.

Are these calcite veins or modern fish poop?

Not sure... Looks more like mineralization to me, but I've flagged our poopy experts to weigh in. :D

Doesn't look like fish poop to me. In your photo, the veins almost look like bivalve shell sections. :)

Hopping on the shell train.  

Seriously doubt you are going to find modern fish funkys in rock with the ammonites.

I'll go along with bivalve cross sections as well. Your ammo ids seem to be correct. I'm just not quite certain about the Pseudolioceras, since the matrix is still covering some of it.

Yes, bivalve cross-sections, not uncommon in some of those Yorkshire Jurassic beds. 

Plagiostoma was one I used to find a lot if i recall.
