I have this piece of coral which was from Gotland. But I don't know what coral it is.
It is the same at top one: http://english.fossiel.net/determinatie ... n&pagina=4
I hope you can identify it!

Ik denk het niet.
Jouw koraalkolonie zou een Stauria kunnen zijn. Moeilijk te zien.
Je kan de steen eventueel zagen en polijsten of etsen in een oplossing van water met zoutzuur. Wel oppassen voor je eigen veiligheid!

Here is the back of it. I can't get the side (which looks exactly like the one on the link) yet as it is much smaller. It is hard getting these images.I hope this will help!

OK, with my new camera, I can take close ups, are these any good? Will they help?

I have heard that it is Silurian.
