Hey guys this coral keeps drawing my attention. We have hundreds of horn corals and pretty sure this is one, but it looks different than the others? Do you think it just preserved differently or could it be a less common type of solitary rugose coral? Any thoughts appreciated and thanks for looking!

All, I went fossil hunting at a new site a little north of downtown Nashville and hit paydirt with these large pieces of rock; they are absolutely packed full of rugose coral

Hopefully this will be quick and easy for those who have the knowledge. I was meandering in the hills and came across some horn corals. I am used to calling the smaller one on the left a horn coral. I am presuming the one on the right also a horn coral. Would someone kindly provide sufficient naming to each so I can do some offline research and reading? Apologies for fuzzy pic. Camera seemed to only want to focus on the backdrop material.

A common coral in Bundenbach. Taxonomy from Fossilworks.com Description from Südkamp 2017, p. 32:"The rugose corals assigned as Zaphrentis are also called horn corals after their familiar form. The transversely round chalk section of the polyp is divided by numerous, radiating septa sticking out interiorly. The calyx is deep." Identified by oilshale. References: Südkamp, W.

Hoooooooooooorrrrrrrrrrrraaaaaaayyyyyyyyyyy!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Here we are at last, into Adam's Silurian. Thanks for looking. First up is the Lower Silurian or Llandovery and I begin with a problem. I posted this one incorrectly in Adam's Ordovician as it had got it's label muddled up with an Ordovician Favosites I had that has vanished in the move here, but is being replaced by kind forum member @Herb Anyway, this, I remember now I've found the correct label, is from the greenish Browgill Formation, part of the Stockdale Group from a cutting near Skelgill (Skelghyll) in Cumbria, Northern England. It seems to be a tabulate coral, but I can't find any listed for this location, only mentions of small, rare, rugose corals. It has the star shaped corallites of a Heliolitidid, but seems to be tightly packed together like a Favositidid. A couple of species of Palaeofavosites seem to be close and are a bit star-shaped,, but anyone know any better? @TqB@piranha hmm who else? The coral bit, an external mold, is a maximum of 3.5 cm across and each corallite up to 2 mm.

Polished Horn Coral fossils SITE LOCATION: Western Sahara, Morocco TIME PERIOD: Devonian age (358-416 million years ago) Data: Horn Corals are from the extinct order of corals called Rugosa. Rugose means wrinkled. The outside of these corals have a wrinkled appearance. Horn Coral grows in a long cone shape like a bull’s horn. The fossil is the skeleton of the coral animal or polyp. They built these cone shaped structures from calcium carbonate that came from the ocean water. The animal lived at the top of the cone. As the animal got bigger it added more material to the cone. Each layer was a little bigger than the previous one. All corals belong to the phylum of animals called cnidaria. They are related to jellyfish which are also cnidaria. While modern corals are colonial the now extinct horn corals could be colonial or solitary animals. They had many tentacles sticking out to gather food. The tentacles gave them a flower like appearance. The oldest of the Rugosa corals are found in rocks from the Ordovician Period. Many species evolved during the Paleozoic Era. As a group they flourished until the Permian Period when they became extinct along with most living things during the Great Permian Extinction. Kingdom: Animalia Phylum: Cnidaria Class: Anthozoa Order: †Rugosa-

I was out cleaning windows at one of my clients properties when I stumbled across this beast! Let first explain that the property has large limestone (I think?) rocks going around the edge of the property, these where placed there in the late 50's or early 60's. I climb over these rocks to get to some of the windows and it shames me to admit that I never noticed it before . But anyway, there I was cleaning windows when something got my attention...FOSSILS! So, I went to the owner and asked if I could remove a few, they said "sure, get rid of the junk!" I took what I could safely transport and said I would be back for the rest tomorrow and that was today. So, here are a few pics of my find, I will post more later, wifey needs to eat and I am getting a look as we speak . I used a yard stick for scale.
