  1. Last weekend we went back to the area of Chimay in Belgium, the quarry has been exposing some interesting anoxic deposits lately. There has been a little bit of movement with buldozers, so we had acces to fresh material. So it didn't take long for the outlines of the first goniatites to apear. We found quite a few promissing specimens that I've been starting to prep this week. ( mechanical en chemical prep) Placoderm: Prep time, 1st batch stil work in progress:
  2. Last wekend Natalie and I had a quick little field trip to my favorite quarry in southern Belgium. The prospecting was done in the rain, but it cleaned of the dust of the sree piles, so we did find some decent stuf. Most of it were goniatites, but Natalie also found a nice orthocone and we did find quite a few placoderm remains. Natalie found this nice loose Manticoceras, just a little chemical preparation and the air scribe to clear out the center: The orthocone she found, after the prepp: One of the Manticoceras I found was a lot harder to prep: a fragment of a median dorsal plate from a large arthrodire placoderm: And a little nodule with a very well preserved bone fragment, It turned out to be the posterior part of an infragnathal

    Late devonian placoderm prep:

    Natalie and I have been hunting the late devonian deposits for a while now. And from time to time we do find some small fragmentory placoderm remains. But this time Natalie found something realy exquisite. A well preserved placoderm plate in the shales, after tring to get it out we found out ( the hard way by hitting an other bone fragmet during extraction) that there was a lot more in there than just that one armorplate. So to be sure we had to somehow take back a stone slab from around 60cm long to avoid losing some parts. It has been lying around at home for a while now in wait of some new prepping equipment ( micro sandblaster) and when we recently got the new tools I started the prep of the placoderm. It took a while to clear up as much as possible, with still a few fragments in the harder matrix that I didn't get completely free, but for now the piece is done. Some of the parts that were uncoverd were: The median dorsal plate, pre-and postorbital, antherior supragnatal, Inferognatal and more... the fish should be a type of Coccosteid placoderm. I've already contacted some paleontologists that I worked with before on devonian fish to see if we can get more info out of it. So here is Natalie's placoderm: as found: during the prep: and the end result:

    Before and after

    Hi there, It has been a long time that I posted some of my finds. Last weekend I found a nice goniatite in de devonian deposits of Belgium. Thanks to @Manticocerasmanfor the prep
  5. Our fossil shed is finally done, with the last work of the carpenter to install a door and the last bits of insulation. So now it is time to clean up the place and reorganise a little. This weekend I took a selection of my best material out from the Lompret quarry in Belgium and started to reorganise it. Most of it are Gephuroceratidea goniatites like Manticoceras sp. And Crickites sp. , but also some Oncoceridea, Orthocones, crinoids, placoderm and more. I’ll be taking more pictures this week when I keep on filling the cabinets. pics on both sides from the 1st table: 2nd table: time to fill up the cabinets: The Manticoceras sp. cabinet: ( close up's will follow )

    Orthocone prep

    Appart from the ususal goniaties that I find in my favorite hunting spot, I do find some other cephalopods there from time to time. Last trip I found a realy nice orthocone. the fossil shell is 18cm long. I used a combination of mechanical ( airscribe ) and chemical ( potassium hydroxide ) prepparation. pictures as found, during prep and after prep:

    Backlog fossil prep

    The last few fieldtrips didn’t deliver a lot of fossils, so now I got time to get started at my backlog of fossil preps from the Lompret quarry. I still have well over 100kg of material to sort and to prep from there. Last weekend while rummaging through a few of those boxes I picked up one that got my interest. A Fragment of a large nodule with a part of a nicely sized Gephuroceratid poking out. After a good look, there were a couple of other fossil fragments visible in there, sadly the matrix was extremely hard. I had to use a grinder and hammer and chisel to get through it, the problem was that apart from the few visible specimens I was grinding in to it blind, so It happened that I grinded through a few fossils that weren’t visible on the outside. But from time to time I was lucky and exposed a few more fossils, including a nice small pyritized Manticoceras. After that I got the specimens out, I used a grinder to go over the matrix and used colour deepener on the fossils, this gives a nice colour contrast between the fossils and the matrix. The fossils visible on the finished piece are: a few Gephurocertids like Manticoceras sp., a little Tornoceratid, a Bactrites sp., a fragment of a nautiloid orthocone and a brachiopod Ryocarhynchus tumidus. The piece is from the late Devonian, Frasnian, Matagne formation near Chimayin Belgium. A goniatite poking out Grinding, chiseling and airscribing... almost done: All cleaned up picture with scale:

  9. It has been a while since I’ve prepped a good Manticoceras goniatite. I still have a few lying around, but there was one from a box from a recent field trip that I really wanted to clean up. The specimen was partially sticking out of a massive piece of limestone and it already showed some really nice suture lines. So yesterday I finally tackled it starting with the grinder, then chisel and hammer and the details with the air scribe. I did make a mistake with the grinder by getting to close to the fossil and scratch the surface in one spot, but in the end after applying some colour deepener for marble it is almost gone. before the prepp: starting to grind and chisle: finishing up with the air scribe: the end result after the colour deepener:
  10. On the last few fieldtrips to the quarry in Southern Belgium where we look for goniatites we found quite a few plant remains in some of the anoxic marine deposits. A friend of mine thought that one of these remains could be Protocalamites sp. , but we find verry little info about that plant. Does anyone know when they first occurred? The layer where we found the remains were from the Late Devonian: Frasnian – Matagne formation ( Upper rhenana conodont Zone ) Any comparison pictures or papers on this subject are welcome.

    holiday goniatite hunt.

    During our holiday in the ardennes we made a compulsory stop at our favorite hunting spot for devonian cephalopods. There has been a lot of new activity in the quarry, but sadly not in the best deposits for fossils. They are also starting to fill the older spots with ground. But the usual exposures were still delivering some goniatites from time to time. And we dit get quite a good haul this time. There was one notabely well preserved Manticoceras sp. and as a bonus we had a rare nautiloid. I cleaned up a couple of the goniatites with chemical prep; the result was spectacular.

  14. It has been a while since I’ve posted some goniatites. The expansion of the quarry where I look for them is nearing to the end, and most of the good layers are gone. but sometimes we still find some neat specimens. this one was found a month ago. I used potassium hydroxide for the prepp of this one. The chemical reaction worked realy well on this specimen. Manticoceras sp. Late Devonian, Frasnian Belgium.
  15. We recently moved to a new house, so It has been quite a busy few weeks since we last made a field trip. So I hadn’t much time to post the recent finds. On our last fieldtrip to the Belgian Late Devonian I made an exceptional find that I still wanted to share: I found a large piece of bone sticking out of a nodule. After the preparation and a some research I ‘suspected that the piece was a ADL (anterior dorsal lateral) armor plate from a Dunkleosteus. I’ve sent the pictures to a friend Palaeontologist specialised in Palaeozoic fish who confirmed the ID. Dunkleosteus sp. (ADL) Frasnian Chimay Belgium
  16. 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 quarry are Brachiopods, Bivalves, Gastropods, Corals, Bryozoans, Cephalopods like Goniatites and Othocone Nautiloids and in very rare cases Placoderm and trilobite material (although no one was that lucky during the excursion). The quarry is also very rich in minerals like Baryte, Calcite, Quartz, Galena, Fluorite, etc... I have long looked forward to visiting this quarry, so I was very happy to finally be able to go and it did not dissapoint! It was quite foggy in the morning when we arrived which both looked eerie and cool at the same time, luckily it later cleared up! There where quite a lot of other people in the quarry (mainly people looking for minerals like Byrite and Galena) but our club headed straight to higher plateau of the quarry where some of the black Matagne Shales where with very nice Pyritized fossils and to where the waste heaps were to look for fossils. That's me looking for Brachiopods and pyritized Goniatites and Bactrites. A large Hexagonaria coral which was a little to heavy to bring home We also found some Pyrite cubes which (although very exhausting) we managed to extract

    Well preserved goniatite prep.

    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. Late Devonian ( Frasnian ) Matagne formation Chimay area ( Belgium )

    Fossilized raindrops?

    This dolomite stone was discovered near Chasm Creek, central Arizona. It appears to have the fossilized impressions of raindrops splashing into a fine muddy surface. The stone seems to be dolomitic, as HCl causes a low fizz, unlike typical limestone's more energetic fizzing. Most of the "splashes" have the central "rebound" splash seen in my high-speed imagery of water droplets. That central rebound appears to have been broken off over time. Does my assumption that this is a somehow frozen-in-time rain shower make sense?

    Devonian fieldtrip with a view

    Last Saturday we went on a new fieldtrip on one of our favorite hunting spots for Devonian fossils. Not a lot of fossils were found and the only large goniatite, although pretty at first sight turned out to be a nightmare to prep with little to no preservation further down in the nodule. On the other hand we had verry sunny day with nice views over the area and the first flowers taking advantage of the sunlight on the older scree piles. We also brought home a few small nodules with tornoceras fossils , they will take a while to prepp before we will see if they were worthwhile.
  20. 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

    double goniatite fun

    It has been a while since I've found a decent sized goniatite on my favorite huntingspot, since the good deposits are no longer accesible. But recently I did find a specimen in a recent buldozer track. sadly the specimen has taken a hit from the vehicle moving over it. The extra bonus on the other hand was that there was a 2nd specimen right next to the 1st one. I've rarely seen 2 Manticoceras sp. from this size on the same matrix, so I was very happy with this one On top of that the preparation went realy smooth

    Pachyphyllum nevadense

    This is a small form of Pachyllum nevadense that has corallites with small corallas (the circular structures that have a high rim that stick above the surface). The coralla rim diameters range from 1.25 mm to 2.5 mm and average 1.5 mm to 1.75 mm. The corallites average 2.5 mm to 8 mm apart center to center with an average of 4 mm to 5 mm apart. They have an average of 20 septa. The measurements partly overlap with those described for the species by Stumm in 1948: coralla rim diameter of 2 mm to 4 mm; average of 3 mm; distance from corallites centers of 5 mm to 10 mm; 18 to 24 septa. Since there is a lot of variability of the species in the same colony, at the same site, from site to site in Arizona and the US, I consider that this a variety of Pachyphyllum nevadense.

    Scaumenacia curta Whiteaves 1881

    A juvenile lungfish (11cm) from the famous Miguasha fossil site, now a UNESCO World Heritage Centre. Taxonomy from Fossilworks.org. Emended genus diagnosis from Cloutier 1996, p. 199: " Maximum depth of body one-sixth of its total length. First dorsal fin low, with maximum height from one-eighth to one-seventh its length, originating at the level of the fourth supraneural. First dorsal fin 16% of total length without ossified radials; second dorsal fin 30% of total length, and higher than first dorsal fin, itsmaximum height amounting to two-thirds of maximum body depth. Traquair (1893) erected the genus Scaumenacia based on the presence of a "double dorsal fin"; however, the presence of two dorsal fins is plesio- morphic and therefore non-distinctive for the genus. Hussakof (1912, p. 136) provided a series of distinctive features for Scaumenacia, some of which are used in the amended diagnosis." Diagnosis for the spcies is identical.

    What the...? What is this?

    This “fossil?” Confuses me. Is it even a fossil? The shape throws me off makes me think its artificial but i found it in the middle of nowhere on rocky river shore. Geological?
