From the album: MY FOSSIL Collection - Dpaul7
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 -

Would anyone happen to have a pdf of the paper found below please... Zaphrentis and the Zaphrentidae (Devonian; anthozoa, rugosa) by: W.A. Oliver Jr. Bulletins of American Paleontology Issue: 372-373 page: 5 - 24

Hello again just wanting to confirm that this is a rugosa coral that I found in northeast missouri. Thanks.

Hi all. This is my first post to the ID forum. I'm stumped on this one. It was found near Kingston, NY. Comes from Middle Devonian Hamilton Group (probably Marcellus Fm). Matrix is a brownish-gray shale. It's a mold of something with small branching (or budding) tubes, dense transverse rings, terminating in cone-shaped depressions. My first guess is some form of branching rugose (horn) coral, where each terminal cone is a corallite. But I wonder if it might also be a sponge -- though sponges usually don't preserve like this, right? In the pictures below, the scale bar has divisions of 1 cm, and in the last photo there is a penny in the background for scale. Thanks for any ideas... Bob

Thailand dinosaur teeth warning
-Andy- posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi all, a new listing just went up for a pair of Siamosaurus teeth. Siamosaurus teeth are extremely rare. I might be tempted, if not for the fact they are misidentified fossil corals, possibly Rugosa family. You can tell by the vertical lines running down the body, the lack of the distinct theropod teeth shape, the huge size of the fossils, and the poor provenance data (they are identified as Miocene). I have messaged the seller about this mistake. Take care to warn anyone you know who's looking for rare dinosaur teeth.

A few bits to move on. What do you have? I like ammonites but am open to ideas

I broke this out of a very hard chunk of Osagean limestone from Lawrence County, MO. The top disintegrated, unfortunately. There was a hole in the rock about the size of a penny, which allowed my daughter to spot the fossil. But that meant it wasn't protected from weathering, and as a result parts of the top were the consistency of rust when we found it. It appeared that the septa originally converged to a nice point. Is this rugosa? And if so, what type?

I have had my nose in creek rocks since I discovered my first crinoid stem at a camp in Fairview TN when I was 8. Back then I thought it was indian money, but now I know that it is an even better treasure from the past. Currently my collection is composed of crinoids and rugosa corals, but I hope to find many other sea species. I continue my modest creek digging and hope to share my finds with you all and hopefully get help when I can't identify something. Attatched is a photo of the stems and segments I found as a kid. But I have many more fossils where those came from and will love to share in future posts. Thanks! -Alexandra

I have been told that this is a piece of rugosa coral. It was found about 5 miles from the Tennessee River, near Scottsboro, Alabama. What do you think? It was found on a gravel road with similar colored rocks, etc. about 50 years ago. Age? Era?
