Sea Star Help


Ptychodus04

Recommended Posts

Here’s a real test for the TFF community. This slab of sea stars was part of a collection purchased by a friend and it has no data whatsoever. I’m trying to find possible ID for the 2 types as well as possible location. The matrix is a gray sandstone where not weathered but it weathers to a dark tan.

Sorry to report the bad news.  These are fabricated, carved and painted.  

I’m not so sure about that. I don’t have them in front of me and I only had a few moments to actually view the slab and it didn’t scream forgery. I’ll try to get some better pictures...

Here is the proof:

 

The attached images illustrate the features to look for in authentic ophiuroids from Morocco.

Including the most recent paper from B. Lefebvre, the Moroccan ophiuroids remain undescribed.

They really do look carved, and definitely painted.

While I’m hopeful that a closer inspection reveals something different I’m also willing to defer to the opinion of my expert associates here. :1-SlapHands_zpsbb015b76:

 

I’m certainly glad this wasn’t my purchase and it’s exactly why I have never purchased a fossil.

 

I’m not like the great and powerful @piranha, an inexhaustible fossil reference catalog.

Sorry to say, but these look like the typical Moroccan fakes to me. Sadly, there are a lot of plates like this out in the streets for sale and I often see them on the net. Often it starts with a plate with one or two genuine, but badly preserved and/ or incomplete specimens which they then just keep adding to. I think I can see some bits that were real. 

Here's a real starfish.

And a real ophiuroid
