From the album: Trilobites
Along with a couple of rugose corals (Enterolasma?). From the lower Devonian Haragan Formation in Clarita,Oklahoma. Obtained on a trade with Shamalama. Thanks, Dave. -
Looks to me like concentric rings with barbs leading to a central maw. My first guess was a heavily eroded Sea Urchin, but now I'm not so sure? Any ideas? Approx. 40x40x20mm Found on Oddicombe Beach, Devon, England

I recently bought this strange Cyphaspis from a French dealer. Due to the great diversity of species in this genus, I have not found anything about the exact species. Can you help me in this case?

The Devonian period is known as "The Age of Fish", but could also be known as "The Age of Brachiopods." In the Early / Lower Devonian, brachiopods reached the height of their diversity towards its end in the Emsian. We see the ancestral groups occurring, lingulids, craniids, orthids, protorthids, pentamerids, rhynchonellids and strophomenids, as well as the later successful groups we have seen before such as atrypids, athyrids and orthotetids, plus the rise of spiriferids, spiriferinids and productids and the beginning of the terebratulids. By the end of the Devonian , several of these groups are extinct or severely reduced in importance and brachiopods never quite recover. Also, the Devonian is the last time we see trilobites with such variation, large sizes and numbers and orthocerids too are much more uncommon after the rise of the goniatites. The massive tabulate coral reefs also disappear after the Devonian. Fascinating period and I hope to share some of its wonders with you. Equally, a lot of this is rather new to me, so I would be very grateful for any assistance, corrections or further information on my specimens. Thank you. The Early Devonian epoch is split into three stages, so let's start with the first of those, the Lochkovian, that began about 419 mya and finished roughly 411 mya. I have been sent a nice selection of brachiopods from the Kalkberg Formation, Helderberg Group by the Mighty @Misha, mostly. But the kind gentleperson also sent me this fascinating little bryozoan hash : It is dominated by fenestellids, which is usually the case in the Devonian, but other orders sill occur. These ones, I think, are Fenestella, but there are so many species in the formation that I wont take a guess as to species : Not sure what this one is ;

Hello I found this in the rocks in Devon back in July and haven't gotten round to trying to identify it. If anyone has any ideas please let me know your thoughts. Thanks Alvin

Please tell me what brachiopods are these? They come from Morocco, Devonian-Carboniferous. Thank you!

Hi I found this yesterday on the beach in Sidmouth, East Devon, UK It was nestled in the rocks and part of a longer specimen- I was intrigued so was feeling around it and all the sand around it was loose (tide coming in, rock pools) and this middle section just popped free! I didn't have any equipment and wouldn't know what to do anyway so I brought it home rather than leave it as it would have been lost to the sea! There are others around, visibly. I am not even sure that this is fossil vertebrae but wondered what you guys think as I have seen similar photos online before. It's a shame I couldn't extract the rest but it's all still there, firmly attached to the rock. Any thoughts? There is also a mini fossil (wood louse type shape) on one end. I have no knowledge whatsoever although I love fossils and have collected some over the years in the somewhat drier region of Provence, France! Initial photos on the beach, wet. The others on 5mm squared paper at home. I haven't cleaned it up yet...

Hi guys, I thought I’d give you a bit of background first, Wilmington quarry (bovey lane pit) was a quarry located in Devon that closed many decades ago. It was well known for its vertebrate remains but due to strict access, there isn’t too much material floating around, even in older collections. anyway these fossils come from the Wilmington sands member of the grey chalk subgroup, upper chalk anyway I can’t really find any literature on it so I’ve based my id’s on the gault clay which is only slightly older, feel free to correct me 1. squalicorax primaevus? You you can see faint serrations on it so I’m not sure 2. The serrations are a lot more pronounced on this so I’m really not sure 3.cretoxyrhina aft. vracanoensis? 4. not sure at all 5. I have a lot of these, maybe anoemodus? 6. may be too fragmentary but worth a shot, I have a lot more broken teeth but felt these were most diagnostic 7. ptychodus decurrens? thanks for your help

The bones of mammoths, woolly rhinoceros and hyena are among the remains discovered in a cave during the construction of new houses in Sherford, near Plymouth. They date to the middle of the last Ice Age between 60,000 and 30,000 years ago. https://www.bbc.co.uk/news/england/devon

Hi guys, these Ammonites are from the cenomian phosphatic chalk layer found in the Wilmington white heart lane pit in the 1970s and I was wondering if it was possible to identify them? Thanks 1. 2. 3. 4. 5. 6. thanks again

Hello all, I found an interesting looking rock while walking along a forest path in mid Devon, and think it could be a fossil of some kind. If someone could give me an idea of what this is, I would be grateful! Please let me know if you need additional photos/information. Apologies if it's just a rock.

I knew already beforehand that this one would take me a dog's age to get it done, so I decided to keep an eye on the time. Sure enough, this took me the better part of 23 hours to get it completed. A hash plate full of lots of Tentaculites sp. from the Middle Devonian Givetian deposits at Hungry Hollow, Ontario. Thanks to Peter Lee for the photo.

I found this rugose coral 2 years ago in the south pit at Hungry Hollow. I didn't take out very many corals that time since I already had a substantial collection of them from previous trips, so I was getting picky. But I really did like the looks of the underside of this one, which is why I stuck it in my pocket. Now I've chosen it for reproduction.

I hope this is the place to learn some knowledge. My husband works in a quarry in Devon and after a blast has come across these four beautiful giant concretions? Which were in a pocket together. I would be interested to know what they are made of. We have washed the one which was the smallest - the only one he could carry -the colours seem to be very red with some orange. There is also another which is around 1.2meters across which we will be adding to our set. I would be interested in any information regarding our new found rocks
