Hello everyone, this my 1st entry is to find some help to identify if these are fossils since I'm new in this world of fossils & rocks. I live in the island of Puerto Rico in the Caribbean and I've seen corals and reefs and these specimens looks like some wich I've seen. Both have cristal or quartz like features all over and the hardness is like that of quartz. One is like cramy orange in color and the other is like ivory or cream in color. But the last one is totally different because there are a ring of quartz bits on top of that sedimentary rock like shown in the last photos. The location where I found them was in a river in the mountains of the east center of the island (not in the coast) Thanks for the help in advance and please excuse if any errors made.

Hi. I'm Marcia, and I joined this forum because I’ve recently become interested in rudists, after buying some property in the west Texas desert that seems quite full of large ones. Now that I can recognize them, I’m finding many smaller ones where I live in Palo Pinto County also. Saw a good convo on here about rudists, so, I hope to learn more from the folks on here, so thank you for accepting me!

Help request! Seeking diagram of scleractinian architecture through time
pefty posted a topic in General Fossil Discussion
I recently saw a wonderful diagram showing the fossil ranges of various scleractinian coral architectures, or at least the ranges of genera typical of those architectures. But now I can't seems to find it again... The diagram included images of the various coral growth forms and was simpler than but otherwise similar to this: If anyone knows where I might have seen such a diagram, please post the url here -- thanks! -
