Moroccan Placoparia species

[mediterranic]

Hello,

Is the Caid El Rami Placoparia's species (like the one at attachment) already known?

Thanks in advance for your opinions.

Welcome to the forum. 

 

Not it sure what you're asking, is it is this species found in Morocco?

Hello,

The question is: we know the genus - Placoparia. Do anyone knows the species? Yes, it is the moroccan one from El Caid Rami ordovician deposits.

We'll stay on Placoparia sp. in this case, then.

 

Thanks a lot for your precious help.

Hello there, guys,

this is a concrection from the quarry studied by Rabano et al (Rabano et al, 2014).

Would this be the Placoparia (Coplacoparia) sp. nov. or the Colpocoryphe sp. described on that paper for that locality?

 

Thanks in advance,

Miguel Pais

This one is Colpocoryphe sp. with a glabella that is narrower at the anterior border.  Placoparia has a glabella that is wider at the anterior border.
