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 g

I recently found this rather good (for the area) and rare goniatite, probably Girtyoceras sp. The innermost half of the living chamber has a mass of small rods which a few knowledgeable friends have suggested are faecal pellets from something that took up residence. It's in an ironstone nodule from a Brigantian (U. Mississippian) shale in Co. Durham, N.E. England. Fairly shallow water, with a diverse fauna of brachiopods, bivalves, bryozoa, small corals, crinoids etc., often broken up. I haven't seen any arthropods apart from small Paladin trilobites which are quite

Took a little trip to Lake Jacksboro spillway and concentrated on the microzone hoping to find some of the little goniatites and nautiloids. Only found a couple that were "big enough" to see , but once I went through my bag of matrix, I was happy to have found quite a few of the microfauna! A few I am not sure of the ID so any help is appreciated! All of these are 1/8 to 1/16 inch Goniatite Peritrochia sp. Nautiloid Gastrioceras listeri same as above, I think Goniatite Prouddenites bosei Goniatite Cardiella ganti

Fossil hunting trip to Lompret (Devonian of Belgium)
ziggycardon posted a topic in Fossil Hunting Trips
Hi everyone! Around 2 months ago on the 16th of october 2021 I went on a fossil hunting trip with the BVP to the stone quarry of Lompret in Belgium. https://www.paleontica.org/locations/fossil/654 The rocks in this quarry are Devonian in age and date back to the Frasnian (382.7 million years ago to 372.2 million years ago) with the finds mostly being from both the Neuville and Matagne Formations. According to Tom our excursion leader this quarry exists out of what used to be coral reefs and islands that formed around atolls. The fossils that you can find in this quar- 11 replies

Howdy all, I did a bit of fossil hunting in Fayetteville AK over Thanksgiving, hitting the Mississippian age black shale the area is famous for, looking for goniatites and any other ammonoids or nautaloids I could find. These concretions were dug out of the lower unit shale and many of them were large, extending over 4ft in length, flat, with an oblong appearance. This was on the surface of a concretion and unfortunately was exposed to weathering and moisture. Not sure what that is. This little guy, it’s just provided for grins and not requesting an ID. It

I found this goniatite at an exposure of the Sausbee Formation (Early Pennsylvanian; Morrowian) in Oklahoma. I have tried in vain to identify it to even a genus level. I was wondering if anyone knew what this goniatite is. The only identifying mark that I could see on the fossil was a single band on the underside, as seen in the third photo. Any help would be greatly appreciated. Thank you so much!

The site I work most often (needmore formation in WV) produces a fair amount of what this forum has in the past generously identified for me as goniatites. I’ve noticed some with vaguely star shaped holes seemingly punched in them, although I’ve yet to have the chance to photograph one. Yesterday I came across this partial goniatite impression in situ with a really good example of what I’m talking about. Any ideas of what I’m looking at? It looks (to my amateur eyes) like something that occurred pre fossilization, and they always present just this way (overall star shaped with a penetrating ci

I will trade these fossils for one well preserved European goniatite or European triassic ammonite (specimen with 5 to 8 cm preferentially) because that kind of specimen is lack in my teaching collection. Note the Anorthopygus orbicularis is not a common species and, apart the incomplete test, has an exceptional detailed preservation, rarely seen. Best regards, Ricardo Traded

Here are three views of a 9 mm "Peritrochia sp." Girty 1909. It was found at the Lost Creek Lake spillway in Jacksboro. This proves that even a broken, partial fossil is worth taking home. In the first position you see the elaborate suture pattern characteristic of these Goniatites on the outermost whorl preserved. Notice the slight horizontal groove near the bottom edge. As it turns to reveal the next whorl below you can see the siphuncle as a vertical line and the outer edge of a septum, or chamber wall, at the bottom. Turning into the innermost whorl the septum comes into view a

This reminds me a little of some of the Madagascan Cleoniceras ammonites, but the sutures are... unusual. Somewhat rounded at the ends. It's 86x69MM approx. I'd appreciate any input.

Lately Natalie is surpassing me on finding cephalopods. It is not every day that we find a Crickites sp. In the field, let alone a well preserved specimen with the living chamber. So I went to work to prep her precious find: It was a very promising looking specimen and it lived up to the expectations. Crickites sp.

Texas Pennsylvanian Weekend - Trilo, Crinoids, Goniatites and More!
JamieLynn posted a topic in Fossil Hunting Trips
The Paleontolocigal Society of Austin monthly field trip was last weekend - we planned to hit a couple of spots in Brownwood. Well it's a bit of a drive from San Marcos, so I decided to make a mini two day trip out of it and stay in an Air BNB (a great option for traveling these days - no shared air source like a hotel!) . So instead of just the two sites on Saturday with the Society, I headed up to Lake Jacksboro for some solo hunting! And boy was it solo.....not a SINGLE person at the site! I was astounded. Had the whole place to myself for HOURS! It was a beautiful day - 70s and sunny. I c- 24 replies

On a recent fieldtrip I found a verry large and promising looking goniatite. The center of the specimen was covered in claystone. I tried a combination of mechanical prep with air scribe and treatment with potassium hydroxide. Removing matrix as close to the fossil as possible and then treating it with potassium hydroxide. I repeated this process a few times until I managed to clear out the whole center of the fossil. before and after pictures: Crickites sp. Frasnian ( Late Devonian) Belgium

I'm unable to identify these goniatites from the Finis Shale member of the Graham formation. Found at the Lost Creek spillway near Jacksboro Texas. At first I thought they were just extra large examples of Agathiceras sp. which can be found there because of the longitudinal lirae but I noticed some other differences. These are more evolute as well as being larger. They also have a larger whorl height to whorl breadth ratio at 1.11 to 1 compared to .85 to 1 for Agathiceras. This one shows the larger umbilical diameter of 10mm and he

A couple weeks ago I met with a retired paleontologist that specializes in Pennsylvanian cephalopods. I showed him all my finds from a certain site here in NE Oklahoma and he was kind of surprised with what I had found (and wasn’t finding). There were a couple common goniatites and nautiloids, a few uncommon ones and five specimens of one type of goniatite he didn’t recognize. He checked his book and still couldn’t match a suture pattern and told me it may be an undescribed species. He noted down the pattern and said he was going to double check, but if it ends up being the case, he would pote

What type of fossilization is if we see a flat white orthoceras on a black stone? Many sellers cut the stone in the shape of orthoceras shell, to believe that is the whole animal sell. Please help, because i can't understand what type of fossilization is this.

This weekend we finaly got out after those long months of lockdown. This time I am prepping a gephuroceratid that Natalie found. They are often found on top of the limestone banks, but this time she found one peeking out the center of the limestone bank. The position of the fossil didn’t make the prep any easier, since I had to grind away as much as possible of the matrix with a powertool without cutting in the fossil. Luckily I just missed a 2d goniatite hidden in the matrix with the grinder. After 4 to 5 hours of prepping with grinder, chisels, with air scribe and a
