Ichthyosaur Tail Fossil


Mousehead

Recommended Posts

Hello!  This one looks suspect to me.  The smoothness of the bones and the lack of closeup photos to see any air bubbles/casting artifacts makes it hard to discern here.  I'm also going to call out the little crevice surrounding the fossil that separates it from the matrix, which to me suggests it was planted into the surrounding rock.

 

Info:

Ichthyosaur communis
Llavernock beach, South Whales, UK

I also see red flags.. cutline along the vert string and the matrix color on vert string is lighter than the plate.   All real agree but could the verts have been added to enhance appeal ?  Best to hold an item like this or if purchased insure it can be returned.

In my opinion it would be a very difficult fossil to fake, especially to put the vertebrae like that in the matrix so they’re properly embedded. Not even talking about the small rib bones.

Still real.

 

Here’s a before prep shot. The shale will have delaminated during prepping which is why you can seen that line.

 

I know the person who found and prepped them. It’s not worth faking.

As said: real, not worth to fake it (not soo really rare...).

Note: Especially in former times, it was not unusual to put fossils from that horizon (jurassic black shale "Posidonienschiefer") into matrix.
