Diplocaulus

Recommended Posts

Recently purchased this squid from the Tucson show. Looked a little off to me compared to the photos online but still bought it on a whim. Does it have any significant touch-ups or fakery? Thanks in advance!

From Lebanon?

 

I don't know that I've ever seen one that was that well defined (which makes me suspicious). I'll wait for the experts though.

Supposedly from Solnhofen, Germany

@Diplocaulus This is most likely a species of plesioteuthis of the Jurassic era dating back 150 million years, which many of the fossils remains being found in Solnhofen Plattenkalk - Eichstatt, Germany 

 

To me this seems restored or fabricated to some extent, you don’t really see the calcite crystal preservation of the squid parts such as the mouth and tentacles. I’ve attached below an genuine example of the same species found in the same Solnhofen locality and you can see the differences in the fossil

they would look more like a cuttlefish rather than a squid or am I wrong?  what can be glimpsed is the typical cuttlefish bone inside?

@Francesco1994 the picture that I included above is a species of squid, the earliest fossils of cuttlefish are from the end of the Cretaceous period and know from the species Ceratisepia

 

I’ve attached a great resource to help identify and distinguish fossils and biology of body structure antatomy between squid and cuttlefish as they can be very similar in the fossil record

Thanks for the info. It's a little disheartening to find out that there's a bit of fabrication, but at least I'll know better next time. Thanks again!

Unfortunately, I think this may be mostly a fabrication, if not entirely fabricated.  :( 

Looks like it is sculpted, to me.  :unsure:

I show you one in great condition with arms, this is how they normally look when they are perfect

Split-pair, top: complete one, bottom: setmarks of the arms

I only know preservation of arms like the ones from the thread from Lebanon
