Mahnmut Posted May 20, 2021 Share Posted May 20, 2021 (edited) Hello dear fellow forum members, I just aquired a nice little hashplate (if I can call it that?) from Portugal. The information given is the following: Ralfina lusitanica and Helopora sp., upper Ordivician (hírnantian fauna) Queixoperra Member of Cabeço do Peão Formation, Amendoa-Maçao Portugal. What caught my eye is the rib-like structure on the right/ top right. I am not saying these are ribs, just describing the shape. Does anyone have any idea what this might be? Thanks and Aloha, J Edited May 20, 2021 by Mahnmut correction 1 Try to learn something about everything and everything about something Thomas Henry Huxley Link to comment Share on other sites More sharing options...
Rockwood Posted May 20, 2021 Share Posted May 20, 2021 Appears to be a fragment of something composed of several layers with a thickened rim. An arthropod molt would do it ? 1 Link to comment Share on other sites More sharing options...
Mahnmut Posted May 20, 2021 Author Share Posted May 20, 2021 You think Trilo? That would be cool. At least a the end of the long structures, where there is only an impression left, its clear that they are tapering cylindrical, well, things. The repeating pattern looks arthropod. Would have been a big spiny one. Cheers, J Try to learn something about everything and everything about something Thomas Henry Huxley Link to comment Share on other sites More sharing options...
daves64 Posted May 20, 2021 Share Posted May 20, 2021 (edited) Looks like there are more layers (squared area) & it's got me curious as to what that area looks like on the other side. It is a beautiful piece, no matter what it might be. Edited May 20, 2021 by daves64 1 Accomplishing the impossible means only that the boss will add it to your regular duties.

Mahnmut Posted May 21, 2021 Author Share Posted May 21, 2021 You nailed it! Spacetime coordinates do fit, Ordovician, Portugal. Shape and size as well. Thanks! Buying Bryozoa and getting a Trilobite is nearly as good as finding it outside. And yes, I also like that piece. Backside and cross-section are unremarkable, I will take a picture when I find the time. Thanks for all your help! Can I change the title to add "solved: Selenopeltis"?
