How Big Is Your Rugosa/ Horn Coral?

8 posts in this topic

Found this rugosa coral in a rock blasted in a quarry. It measures 12 inches and has both ends broke off!! Show us how large your horn corals are! Still need to clean this one up a little.

That sure is a monster! Up here, the largest ones I find are about 6-8 inches, but the tabulates can be enormous.

The ones I find get big around, rather than long.

Yes, we had a quarry hunt with the Cedar Valley Fossil Club. It was a rock that was in a pile and ready for the crusher. Wished I was able to get the ends that were missing.

Nice corals everyone!!

Some rather nice corals here.  I do have one that I kept from years ago that is quite large, but have no idea where its at at the moment.  i will run into it someday.    Those ones from JimB88 are really nice!

Spectacular material!!!!:dinothumb:

More of the carbonic acid ion in paleozoic seas ,good food supply, high intrinsic growth rate,hardworking symbionts?

No predation?

Would we we like to know what caused them to become large?I would.
