Eureka Posted January 7, 2009 Share Posted January 7, 2009 Hi, friends. First of all I wanna wish you a happy new year and great fossil findings for the next months! I just need some help. I enclose a picture of a fossil in its matrix. The specimen was found in north of Spain. It was found in a Lower Cretaceous period area (to be more accurate Albian material). It is a seaurchin....but what´s exact species name? any clues? Best regards and thanks!! Eureka Link to comment Share on other sites More sharing options...

In Aptian C.royoi exist in iberian peninsula, and also C. (Micropedina) olisiponensis in the Cenomanian strata, why not in the Albian? http://www.mbfossilcrabs.com/ Link to comment Share on other sites More sharing options...

Air scribe? Link to comment Share on other sites More sharing options...
Eureka Posted January 8, 2009 Author Share Posted January 8, 2009 Dear MB, Thanks for the prompt answer. I am not quite sure this specimen would be a Cottaldia...Let´s see, I could even run the risk of calling it Codechinus, unfortunately I can not assure it. Moropus, nice to share this passion with another Northern guy. For your information, this specimen was found like you can see on the pictures....just washed with water and soap.

LanceH Posted January 8, 2009 Share Posted January 8, 2009 It looks a bit like the Pedinopsis we have here in Texas but your echinoid is more rounded and the bumps are more evenly distributed and sized. Here is the Pedinopsis I found in very early Cenomanian age deposits. I'll go through my papers when I get home. Link to comment Share on other sites More sharing options...

Eureka Hi, Your urchin could be a Cottaldia or not, but it is not a Codechinus, look at the ambulacra, the interambulacra , count its pores if I'm seeing correctly, it seems it have a pore pair, and it is not the case of Codechinus, in fact Codechinus is a ball, your urchin it is not a ball, seem a little bit flattened. I could be wrong but it is my point of view. http://www.mbfossilcrabs.com/ Link to comment Share on other sites More sharing options...
Eureka Posted January 10, 2009 Author Share Posted January 10, 2009 Dear MB, Sorry for this delay in replying, due to many duties. After having a look of the specimen in detail, I agree with you, not chance of being a Codechinus. I can not assure it is a Cottaldia variety. Perhaps othe members can add other names to the seaurchin? Let´s wait. Eureka Link to comment Share on other sites More sharing options...
