Beach Fossils

Hi, @corina-fernandes! Favosites went extinct during the Permian-Triassic transition, so the time period on this is wrong (or perhaps the ID is wrong). Unfortunately, I’m not too great with coral IDs, so I’m going to tag in @JBauer and @Mackenzie-Smith.

Thank you @samantha-ocon. Probably I identified wrong the fossil. The area where I found the specimen is the cretaceous period for sure. I will asking for the help of @JBauer or @mackenzie-smith. Thanks 🙂

@Mackenzie-Smith

@samantha-ocon is correct, there are no Favosites in the Mesozoic. I was looking at a geological map of the area and there is a Paleozoic Plutonic Complex nearby. Plutonic implies that it is igneous in nature (so no fossils) but where it is a “complex” I don’t know if there might be a sedimentary layer. Favosites are a tabulate coral meaning that…[Read more]

I appreciated your clear explanation about this element @mackenzie-smith. I don”t geological formation, but the hypothesis that this is a demosponge is very possible. Thank you for your help :). am going to wait for the @JBauer opinion

Very cool, @Corina-Fernandes! Do you know what geological formation this is from? Also, I think the order is Scleractinia.

Thank you, @samantha-ocon. I had studied by answer the your question. The fossil found in cretaceus zone in Portugal. The lusitaniana basin, it’s a sedimentary basin, developed in the Iberian Margin Western (MOI19) in the Mesozoic era. Your dynamical is part for the Pangea fragmentation, in the opening the north atlantic ocean. In the Triassic e…[Read more]

These look a little modern to me.

Hi, @Corina-Fernandes! Are you interested in improving the quality of this specimen for the eMuseum? First thing to do would be to update the geochronology and lithostratigraphy; for example, do you know what geological formation you found this in?

Samantha, I have information about geochronology and lithostratigraphy about fossils. It’s a long information. Do I want post in the coments?

I don’t have geological formation, but I can search papers about the place where I find this fossil. It’ a very important paleontology place in Portugal

However, I know that this beach has a cretaceus albanian formation cowered for miocene Burdigalian sand (in this substrate I find this fossil. I will know more information
