    Opal lungfish tooth plate

    A few days ago I posted on this forum the same fossil but back then I thought it was a bone. Now I know it is a lungfish tooth plate. It was broken into four pieces by a miner. Here are two images of the front and back of the specimen ( hat I tried to reassemble) and two more show how it looks under a microscope. A paleontologist told me it is incomplete. However, except the broken sides I do not see any other edges that appear to be broken. It appears to be a complete specimen. What do you think? If it is incomplete on what sides you believe the parts are mis

    Lungfish scales

    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.

    Lungfish tooth plate

    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.

    Some Kem Kem oddballs

    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
  6. 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, Costadrom

    Lungfish burrows

    From the album: Catskill Formation PA fossils

    Lungfish (Holoptychius sp.?) burrows from Red Hill, Apr. 15 2022
  8. 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 mi

    Mazon Creek Lungfish plate?

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

    Lungfish tooth

    Ornamented lungfish bone/scales are fairly common, but their teeth seem to be comparatively rare. This one is ~ 3 mm in its longest dimension. ^Mottequin et al. (2015)

    Ceratodus latissimus

  14. 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.
  15. 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

    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.

    Fishing in the Devonian 2nd trip

    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 u
  18. 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 t

    Is this a Dipterus lungfish

    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

    Ichno fossil ID help

    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?
  21. 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).

    Ceratodus (lungfish) tooth

    From the album: Triassic vertebrate fossils

    A really nice and very rare 2.5 cm long Ceratodus (lungfish) tooth from a triassic "Bonebed" from a quarry in southern Germany (Baden-Württemberg). One of my best finds from there so far
  23. 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
  24. 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 identifi
  25. 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 s
