purplefossil Posted April 23, 2022 Share Posted April 23, 2022 Hi all, I'm not even sure it's fossil... It's from Northern Spain. Thank you in advance! Link to post Share on other sites
Ludwigia Posted April 23, 2022 Share Posted April 23, 2022 Longtitudinal section. It's a fossil, but to be more precise, we need a more exact location and stratigraphy please. Link to post Share on other sites
purplefossil Posted April 23, 2022 Author Share Posted April 23, 2022 Thank you! Location:. (GPS coordinates removed) The fossil is on a rock that was put there by a local person along with other rocks near a very small fountain. So I don't know the origins of the rock.

Ludwigia Posted April 23, 2022 Share Posted April 23, 2022 Soto de Ribera? That would mean Paleozoic stratigraphy, so it's probably part of a straight-shelled nautilus. 1 Link to post Share on other sites
Mark Kmiecik Posted April 23, 2022 Share Posted April 23, 2022 My first impression is orthocone nautiloid -- but I'm not 100% positive. Link to post Share on other sites
fossilus Posted April 23, 2022 Share Posted April 23, 2022 Crinoid stem cross section? Link to post Share on other sites
Ludwigia Posted April 23, 2022 Share Posted April 23, 2022 I think that it tapers too much to be a crinoid stem. Link to post Share on other sites
westcoast Posted April 23, 2022 Share Posted April 23, 2022 My first impression was also orthocone, however this could be flattened cordaites pith preserved as Artisia, if you happen to be in Pennsylvanian aged rocks.. Link to post Share on other sites

That means no location, no geological age, unfortunately. 1 Link to post Share on other sites

But in this case, it is not the GPS coordinates that mean nothing. it is the fact that it is part of a fountain and it came form somewhere else. Probably local rock, though.

JohnJ Posted April 24, 2022 Share Posted April 24, 2022 GPS coordinates have been removed. When members request a location, they are trying to figure out the geologic setting. "Exact" GPS locations are not needed. In complicated geologic areas, members may offer maps to assist in identifying the local geology. That information can help to identify a fossil and attempt to keep the actual location private, if necessary. 2 Link to post Share on other sites

oscarinelpiedras Posted December 9, 2022 Share Posted December 9, 2022 Yes, it's a crinoid, I have seen a big amount of them in the same area. They are from Alba formation, Namurian, Upper Carboniferous. Marine environment. Link to post Share on other sites
