From the album: Permian
Rhipidistian (lungfish) scales from the Early Permian (Wellington Fm., Waurika, OK). They can be identified by a "honey comb" structure on one side, the other is largely featureless. -
From the album: Triassic
Lungfish are an ancient group of fish, with swim bladders that evolution co-opted as a kind of "lung," allowing them to breathe air. This may have proven invaluable in a seasonally dry climate in Pangea.-

Hello all Yesterday, I could add a few more items to my ever expanding Kem Kem collection. I am very excited with these pieces, but some of them I have a lot of questions by. 1) This weird lungfish toothplate. Currently there are 3 species of lungfish known from the Kem Kem beds. The first and most common species is Neoceratodus africanus, of which the toothplates are described as 'Toothplates with deeply incised ridges'. The second species is Ceratodus humei, described as 'small toothplates with low ornamentation and only four low ridges' Third species is Arganodus tiguidensis, described as 'small toothplates with a characteristic radiating pattern of ridges' I have the first two species, and have only rarely seen Arganodus popping up in the Kem Kem beds. But now I got this tooth: This tooth doesn't match any of the descriptions of the three regular species of lungfish. The only match I could find was Lupaceratodus useviaensis, a extinct lungfish species from the Cretaceous Galula formation in Tanzania. My tooth is a lot bigger however, standing at 4.5 cm and having 8 ridges instead of the 6 of the Tanzanian specimen. So what could this one be? I'm thinking it's most likely a new species or a species new to the location. I would be happy to hear the opinions of the people on here. 2: Double barbed Onchopristis barbs A while ago I made a topic regarding one of these barbs. The general consensus then was that it was a rare pathology, but now I have multiple specimens with double barbs all found at the same location. They are all in better quality then my first specimen and with the exception of some small repairs, no work has been done on them. Would you all still think this is a pathology? How large is the chance that multiple of these would be found in the same spot? All of these are in the normal size range of Onchopristis barbs. Link to previous topic: 3) This is probably a piece of chunkosaurus. Not sure if it's still in any way recognizable. It was sold as Coelacanth skull bone, but I'm more interested in the weird patterns on the bone. I've been searching a long time for traces of invertebrates from the Kem Kem beds (they don't really fossilize unfortunatly) and I think this time I might have found some. Could these tracks (marked in red) be tunnels of some kind of burrowing creature? If anyone recognizes the weird texture on this piece of bone that would be really helpfull.

Hello all! I recently rearranged my collection so I figured this would be a good time to show some fossils! I usually hang-out in the New Jersey Cretaceous but I have been collecting fossils for over 25 years and have found some pretty cool specimens of creatures from many different eras, That said, my collection is mainly focused on the New Jersey Cretaceous, so let's start there. These are my displays for New Jersey Cretaceous non-reptile fossils. My favorites aren't actually fossils at all but rather casts of some of my favorite finds. The crab, Costadromia Hajzeri is the earlies known sponge crab and was named after me. The lungfish cast is of one of two specimens of late Cretaceous lungfish found from New Jersey (probable new species based on time period and 'crushing' element of teeth. The big Xiphactinus tooth is another of my favorite finds along with the echinoids and Menunites ammonite (pictured).

Birthday Fossil Hunting trip to Ardennes (Devonian of Belgium)
ziggycardon posted a topic in Fossil Hunting Trips
Hi everyone! Last weekend I took a couple of days off work for my birthday and I decided to visit a fossil spot in the ardennes which was recently recommended to me because there was a chance to find fossils of primitive plants as well as devonian fish (which is one of my main interests within the hobby). The site is relatively close by as well which was a huge plus as it only took an hour to drive. The fossils in this location date back to the late Devonian, Famennian to be exact (372.2 million years ago to 358.9 million years ago) After searching for a 45 minutes we finally found the top spot with the right layer rich in plant material, here are some in situ pictures of the larger examples (which we didn't extract). If I am correct I believe these are the remains of Rhacophyton condrusorum which is a primitive species of fern if I remember reading once. We were also lucky to find some fossils of devonian fish, which was the main reason for our visit. A lovely small Lungfish (Dipnoi indet) tooth An imprint of a fish scale of bone While it was quite a cold day, it was sunny and we had a quiet afternoon at the spot where we could search in peace.

Had this concretion open today. I'm pretty confident it's something vertebrate. Maybe a lungfish plate? @jdp @RCFossils Thanks for any help.

So here is my 2021 summary of my collecting trips to the late Devonian Catskill formation of Pennsylvania. I have been collecting for the Academy of Natural Sciences in Philadelphia for the past few years. A Tristichopterid skull collected at the Cogan House exit on RT15 in the 2019 season was just described as a new species of Eusthenodon in JVP, Daeschler et. al.. Very exciting! All three trips to PA this year included Red Hill. While the forestry department was very limiting on the use of power tools, they seem to not care too much if people collect with hand tools. The problem is most of the easier surface and near surface material has been collected over the many years the site has been worked. Now, the only way to discover any new tetrapod material is to move large quantities of rock. So that's been the challenge. How much stone can be moved with hammer and chisel with 64 year old wrists? Anyways, I was able to recover a number of interesting specimens although nothing has been id'd as tetrapod so far. These have all been sent to ANSP for analysis. This head plate with what I thought were lateral line canals (Y shape in middle) had a different ornament from other specimens of Hyneria I have. I had also convinced myself the curved surface on the left side and lower image appeared to be orbits but the experts determined it to be just a run of the mill Hyneria post parietal shield. ….It was exciting for a while. Even though this endochondral bone was found in with some exceptionally well preserved material it must have experience some significant transport before being deposited. With a thin blade at the top and some hefty bone at the bottom, I thought this might be id'able but no such luck. I still feel like it must be a shoulder girdle. Not sure what else it could be?? This is another endochondral bone found closely associated with the others. It is minimally a mesomere element of a fin but compares well with the radius of Ichthyostega (see below). Unfortunately, it again being an isolated element has not been id'd at this point. Unfortunately, this mesomere element split when I was removing the head plate. It seems to compare well with an ulna/tibia from a sarcopterygian fin. Here it is with the above "radius"? Finally, the one id'd significant fossil from the season! This bone was found at the Cogan House exit on RT 15. Ted Daeschler was pretty quickly able to id it as a lungfish lower jaw, probably something like Soederbergia.

Hello everyone, The Osteolepis macrolepidotus fossil I recently acquired came with a little surprise, It has a a fairly large impression of a cycloid scale with it, I was wondering if it was possible to identify it. I know lungfishes have these types of scales so maybe Dipterus? I am really not sure, I have been trying to look at the scales of fish found there but have not found many good references. The scale is about 1 cm in length. Any help would be appreciated.

I've always loved living fossils, especially the fish. They are relics of an age long lost, offering us a glimpse of an incredible prehistoric world. Some are enigmas that survived countless extinction events since the Devonian. Others are majestic predators that swam alongside the dinosaurs. Let me present my collection of living fossil fishes from the Mesozoic and before. I will begin with one of the most famous of all - the coelacanth Coelacanth Species: Whiteia woodwardi Age: 252.3 - 251.3 mya | early Triassic Formation: Diego Basin; Middle Sakamena Formation Locality: Ambilobe, Madagascar First appearance: Eoachtinistia foreyi was found 360 million years ago in Australia Paddlefish Species: Protopsephurus liui Age: 125.5 - 112.5 mya | early Cretaceous Formation: Yixian Formation Locality: Lingyuan City, Liaoning First appearance: This is the oldest known species Sturgeon Species: Peipiaosteus fengningensis Age: 125.5 - 120 mya | early Cretaceous Formation: Jehol Biota Locality: Chifeng, Nei Mongol First appearance: Multiple species e.g. Yanosteus longidorsalis found since 125 million years ago in China Pipefish Species: Hipposygnathus sp. Age: 28.1 - 13.8 mya | Oliogocene - Miocene Formation: Monterey Formation Locality: Santa Ynez Valley, California, USA First appearance: Solenostomidae species were found 55.8 million years ago in Italy Note: Although most of this collection only includes fishes that existed since the Mesozoic or later, I made an exception for the pipefish as their order, syngnathiform, existed since the late Cretaceous

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. Line drawing from Cloutier 1996, p. 207: Identified by oilshale. References: J. F. Whiteaves (1881) On some remarkable fossil fishes from the Devonian rocks of Scaumenac Bay, in the Province of Quebec. Journal of Natural History 8(44):159-162. O. P.

After our succes last time to look for Devonian fishes, we went back to te same spot to look for more fish remains. Although the finds were less frequent we did get a couple of realy nice specimens. All the specimens are from the famennian deposits in Belgium. Natalie found a nice Holoptychius scale: And I found a large fragment of fish bone, possible Holoptychius or Tristichopterid. but the find that made my day was a big lungfish toothplate, after a litle bit of preppwork it reveald a stunning specimen: the cleaned up toothplate from the lungfish Dipterus cf. nelsoni :

I can't travel far at the moment so all my hunting for the past couple of months has been in a local Lower Carboniferous, Asbian aged freshwater lacustrine deposit, the Burdiehouse Limestone. This is one of the most laterally extensive beds in the Midland Valley of Scotland and luckily theres a few good eposures of it nearby where past quarrying has left some nice productive spoil heaps. I'm always hoping for complete fish when hunting in this bed but none have turned up so far in the recent hunts. I have been lucky on the tooth front though and came across my first lungfish tooth plate from this bed which I was really happy with The petalodont tooth Ageleodus pectinatus has been the most common find. These were some of my favourites, they range from 3mm to 6mm. I've also doubled my collection of these little Xenacathid teeth but I'm still not sure exactly what genus they belong to. They're pretty tiny little things, the larger of these two is 4mm and the smaller only 2mm. Holocephalan teeth are really rare in this formation so was very pleased with this one, its the largest Ive found so far at 6mm. Not sure of the ID but thinking some sort of Helodontid. The lungfish tooth plate, its still attached to the mandible and the whole thing is only 5mm long! Think its probably a Ctenodus sp. but not sure.

Hi all, I am getting this fish fossil but I want to make sure it is indeed a Dipterus lungfish fossil Seller says it's from Achanarras Quarry of Thurso, and it measures 15 cm long May I have your thoughts on it? Thank you
-
OK, looking for some help with this ID. I THINK this is a lungfish burrow, but I've never seen any before. I'm exploring a new property permission for a Permian Vert site. The reports also describe numerous lungfish burrows, some with the fish still inside, although most are just the trace fossils. This bit of shale has one every few inches and they are roughly 1" - 1.5" in diameter. So whats your opinion?

Carboniferous and Permian boulders in Lithuania- discovery needs confirmation!
D.N.FossilmanLithuania posted a topic in General Fossil Discussion
Dear Guys, During the last several years i detected unknown truth talking about Lithuanian boulders- the Carboniferous and Permian marine rocks are very numerous and their age is various- there can be found almost each stage of Carboniferous and Permian. The main rock types are three- dolomite and limestone with masses of brachiopods that is various in color, stromatolite limestone with mollusks and unidentified cephalon like fossils, and the last- lacustrine limestone with coelacanth scales and possible plant remains (Carboniferous rhabdodermatids are very numerous). Carboniferous period and Early- Middle Permian was not known in Lithuanian glacial boulders so I very need the strong expert, especially who works on Carboniferous- Permian brachiopods. If my age determinations are correct then I will write the scientific book about this discovery and i think there is huge possibility that many of these boulders could be transported by someone glaciation from Northwestern Russia (or Northern Ural) because there are big areas of Devonian, Carboniferous, Permian and Triassic rocks near surface and Northern mountains potentially could be the cold center at some glaciation period in the Pleistocene. I will show all the pictures with fossil identifications and size, maybe someone will tell the opinion about the taxon and age possibilities. Any contact detail or other important information is very welcome! First image- Angiospirifer (Late Carboniferous), 1.1 cm length Second image- Anthracospirifer (Middle- Late Carboniferous), 1.8 cm length third image- Archaeocidaridae sea urchin plates (Carboniferous), 5- 8 mm diameter Fourth image- unidentified brachiopod species from Carboniferous- Early Permian (8 mm- 1 cm length) Fifth image- Atomodesma? bivalves from Kungurian boulder with Waagenoconcha brachiopod (1.7- 2.3 cm length)

ID requested: Triassic Bull Canyon Formation microfossil teeth (Norian Age)
ziggycardon posted a topic in Fossil ID
Hi! I recently aqcuired quite a lot of "microfossils" to kick off my Triassic collection, as I personally find it one of the most interesting time periods and while I am aware possibly not all of them are ID'd correctly I just wanted to get some nice fossils from this time period regardless of their ID's. All the fossils I acquired are from the Bull Canyon Formation, Dockum Group, San Miguel County, New Mexico, USA (Norian age) But I myself am not very knowledgeable yet in this material as I just started my collection but I am aware that some if not most of the ID's on these fossils given by the seller might be wrong as everything I read about the Bull Canyon formation says that the formation isn't that well discribed yet. I tried to make the photo's as good as I could, but it wasn't always easy given their extremely small size, so I hope the quality is good enough to work with. So I am kinda hoping is someone here on the forum would like to give it a try to see if he/she could confirm or disprove given ID's. Thank you in advance! The first set of 2 teeth were listed as the Phytosaur "Pseudopalatus" teeth which after doing a bit of research is considered a junior synonym for "Machaeroprosopus" The next collection of 3 teeth were listed as the Pseudosuchian "Revueltosaurus" The next tooth was listed as a "Theropod indet" tooth, and I know there are at least 2 species of theropod present at Bull Canyon, a Coelophysid called Gojirasaurus and a herrerasaurid called Chindesaurus. But I am not even sure whether this tooth is dinosaurian or not. The next set of teeth were listed as "Arganodus" lungfish teeth And the final tooth was listed as a "Sphenodont" (Rhynchocephalia indet.) tooth with affinities to Clevosaurus (which is found in Nova Scotia, Great Britain and China).jpg.c21fd51aec9f6112713a83e42aadaa97.jpg)

The diversity of Devonian- Early Carboniferous lungfish teeth in Lithuanian erratics, free to discuss!
D.N.FossilmanLithuania posted a topic in Fossil ID
Dear Guys, I recently got a new camera and made the better pictures of all my lungfish dental plates. There are some families identified but I would be very happy to discuss with you about unidentified specimens and features of each dental plate, maybe some of you would know genera of these finds? The age of fossils is Devonian- Early Carboniferous, they are found in Lithuanian erratics (the majority in marine dolomite and some in shallow marine sandstone). The smallest find is 1,5 mm length and the largest is 1,2 cm length. Please tell your opinion about identifications of these finds, any help will be very appreciated because it would be great material for publication The first fossils I show are holodipterid dental plates. The main feature- merged tooth rows with poorly visible odontodes in the top. 4-7 mm length.

My late Cretaceous lungfish from New Jersey
frankh8147 posted a topic in Partners in Paleontology - Member Contributions to Science
Hello all! I was going to wait for the study to come out but I figure since it is now on display at the New Jersey State Museum, I would post this now. This is my late Cretaceous lungfish from Monmouth County New Jersey. It was first looked at here, on this forum (thread below) and was later confirmed by and donated to the NJSM. There have only two late Cretaceous lungfish fossils found from Eastern America so coming up with guy was a dream come true! It's currently being displayed at the NJSM for their "A Decade of Collecting" exhibit. The study on these specimens should be out in a few months so more to come. @njfossilhunter @Trevor
