Unidentified fossil

Recommended Posts

Frauke

Hello, I inherited a 3 inch fossil from my father and would love to know what it is.  I don't know where this fossil came from but it looks like some kind of barnacle or something similar.  It is brown rock on the bottom and crystallized on top.  I have attached several pictures and would be really grateful for any information.  Thank you!

I agree echinoid - it looks very like some Cretaceous flint Echinocorys scutata specimens (so internal mould), with some unusual and beautiful internal crystallisation at the top.

 

Google: flint Echinocorys scutata

It may be worn, and the external features poorly preserved, but that is some beautifully crystallized internal structure! :wub:

Wow how unique. I would treasure it more than any complete echinoid, especially being the family treasure it is! :)

Thank you so much to everyone for your comments, help, and information!  I really love this fossil and am excited to find out more about it.  :)

I'm intrigued by the inked script but I'm no good at languages - maybe Greek?

TbQ, I don't know what language it is either.  That's partly why I included the writing in the pictures. But I think one of the words kind of looks like Krakow, which is in Poland.

I noticed that one too. :) Echinocorys certainly is common in Poland. Maybe someone more linguistic will chime in - they don't all look like Roman characters.

@Frauke Please send us another photo of the script that is better lit and has better detail. We probably can translate this.

Can you read any of this.  See next post for better photo. @Kasia

I hope this is better.  Let me know if I need to re-do the picture.  Thanks!

I think the last bit is Lam for Lamarck. A hunt for echinoids ending in ....oratus named by Lamarck is on

Hi,

it's not Polish - to me it looks like Greek alphabet - and the location seems to be Knossos, in Crete. The name of echinoid starts with "A" and ends with "tus" and then follows "Lam", like already someone pointed out. I hope it helps.

I think it's standard Roman script after all and says Ananchytes ovatus Lam. (not sure about the ending of the genus - maybe -ius or -yus, there are some variations but this is the commonest and is the correct one).

Kudos to @Dryptosaur!

 

Ananchytes Lamarck 1816 is a subjective junior synonym of Echinocorys Leske, 1778. 

Lamarck's type species was Echinocorys ovatus Leske 1778 -see link: NHM Ananchytes . 

This is now probably to be included in Echinocorys scutatus Leske 1778. NHM Echinocorys

 

The location could be a spelling of Kraków (Krackow?), which has Upper Cretaceous deposits.

 

At some point, someone has corrected the gender of the specific name.

So, Echinocorys scutata, maybe from Kraków, looks good . :)

the Leske volume is old,and does not seem to follow the modern conception of a reference work.:ninja:

This might be Echinocorys.

The reference /legenda are so far removed from this plate that is somewhat difficult to tell

@Frauke

This is an Upper Cretaceous echinoid Echinocorys. It seems to be a flint cast with a geopetal indicator structure. This special form of preservation among german collectors is called "Wabenigel", because of its honeycombstructure, resulting in a perimorphosis (or coating pseudomorphosis) of calcedony following (now dissolved) calcite crystals growing on the single calcites of the echinoid test plates.

 

Krakau is the old german spelling for Krakov, not Krackow or Krakow...

 

 

Best regards from my old (and new again) hometown Rostock...  :default_rofl:
