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

Hi all- @mackenzie-smith @samantha-ocon @corina-fernandes – MacKenzie had excellent information. It can’t be a tabulate coral, it could be scleractinian but we should expect to see septae (which radiate into the open spaces like wagon wheels). Which we don’t see here. I don’t think it’s a bryozoan so I agree with MacKenzie’s demosponge idea. There…[Read more]

Thank you very much @jbauer for you help. I found one specimen that maybe can help identify this speciment. Thanks for all! @samantha-ocon @mackenzie-smith and @jbauer
