Hello!
I'm new to the forum and fossil hunting. I've actually come to it by way of hiking. I've been hiking for years and grown curious about my finds. Most I've come across are easily identifiable, but these two have proven more challenging. A geologist friend suggested that they are a type of echinodermata. But since the first has six rays I thought it might possibly be evactinopora radiata. However, the examples of evactinopora radiata I have seen online are significantly smaller than this example.
I know I should have photographed a coin or something next to them to give them scale, but I didn't do that with my early finds. The first fossil, with six rays, was about six inches across at the widest point. The second, with five rays, is about four inches across. I found them next to each other embedded in the rock north of Barcelona at the following coordinates: 42° 08'08.20" N, 2° 14'22.17" E
I don't know if it is of any help, but I added the third photo as an example of other fossils I found in the area.
Any help is appreciated!
