  1. Hello everyone, I recently received two pieces of brachiopod fossils from Poland, both come from the Eifelian in Grzegorzowice. The first piece contains a number of small productids, I am not sure about the IDs but they do look quite similar to Poloniproductus varians that I have seen come from that area so I am wondering if that is what they are. And the next brachiopod is some kind of Athyrid? I wasn't able to find any similar species from this location. I would appreciate any help with identifying these, Thank you for looking!

    Oligophus moravicus (Pauca, 1931)

    Alternative combinations: Diaphus moravicus and Leuciscus moravicus. Taxonomy according to Fossilworks.org. Description of Oligophus moravicus according to Přikryl et al. 2017, pp. 219-220: “The following description is based on the almost complete specimen Tv 1023a and its counterpart specimen Tv 1023b. They show a preorbital length much shorter than orbit diameter. The head is rounded, with an antero-dorsally oriented mouth. The lower jaw joint is located far posterior to the posterior-most margin of the orbit. The maxillary is slender throughout. There is no indication of a supramaxilla. The cleithrum seems to be delicate without well-developed posterior lamina. The vertebral column is not completely preserved in any of the specimens, but the total number of vertebrae seems to be 34 or 35. Remains of ventral procurrent rays are recognizable and therefore the vertebral number cannot have been much higher; about 16 centra are abdominal. Nine pairs of ribs are preserved. The pectoral fins are long, reaching the level of the posterior third of the abdomen, and are composed of about 13 rays. The pelvic fins are located below the dorsal-fin insertion and consist of seven or eight rays; the pelvic girdle is inadequately preserved. The dorsal fin is located at midlength of the body length and is composed of slightly more than 11 rays. The anal fin contains 12 or 13 rays. The body is covered by cycloid scales. The individual photophores are slightly thickened and although the complete photophore formula is not recognizable, a reconstruction of the preserved part shows the pattern reported in Figs. 3 and 4. The fish is slightly distorted midventrally, so that the photophores of the right side area appear to be located higher than on the left side (colour-coded in Fig. 3). The photophores appear to be lens-like. There are faint indications of two photophores just above and below the pectoral-fin base which could represent the PLO and the upper PVO. The four rear PO are preserved, with PO4 being slightly elevated. Five VO, none of them elevated, and three SAO are clearly discernable, the three SAO being located on a straight upward directed line. The AO sequence is apparently incomplete posteriorly and appears to be separated in an anterior and a posterior part. Other photophores are not clearly recognizable. The inner faces of both the saccular otoliths of the specimens Tv 1023a and Tv 1023b are exposed (Fig. 5A, B). The overall outline of the otolith is moderately elongate with a long rostrum, a depressed predorsal rim, a strongly developed and far backward positioned postdorsal angle, a blunt posterior rim and a regularly bent ventral rim. The length to height ratio of the otolith is 1.2 to 1.3. The ventral rim bears 7 strong denticles. The length of the rostrum is about 15% of the otolith length; excisura and antirostrum are weak. The inner face shows a slightly supramedian positioned sulcus with the ostium being longer but slightly narrower than the cauda. The ratio between the length of ostium and cauda is 1.3-1.5. A ventral pseudocolliculum is well developed below the caudal colliculum. The dorsal field bears a large dorsal depression; the ventral field shows a distinct ventral furrow at some distance from the ventral rim of the otolith. The inner face is nearly flat. The outer face is exposed in the specimen Tv 1025 and is distinctly convex and smooth with a postcentral umbo.” Line drawing of Oligophus moravicus from Přikryl et al, 2017, p. 220.

    Propteridium sp.

    Very probably Propteridium profondae Ciobanu, 1970. Taxonomy according to Přikryl, 2018. From Fahay, 2007, p. 649: “The order Ophidiiformes (sensu Cohen and Nielsen 1978; Nielsen et al., 1999) contains the suborders Bythitoidei, viviparous forms with an external intromittent organ, and Ophidioidei, oviparous forms with pelvic fins at level of preopercle or farther anterior, and caudal fin confluent with dorsal and anal fins.” Description of Propterides profondae according to Přikryl and Carnevale, 2018, p. 482: “The head is more or less triangular in shape; its length is contained about four times in SL. The cranial bones are difficult to recognize due to inadequate preservation. The ethmoid region is thick and expanded. The vomer is edentulous. The orbit is rather large; its diameter equals the snout length. The frontals are expanded posteriorly, becoming narrow in the orbital region. The mouth gape is slightly oblique and extends posteriorly at the level of the midlength of the orbit. The premaxilla is poorly preserved and bears a single row of tiny and well-spaced teeth. The maxilla is distally expanded and spatulate. The lower jaw protrudes anteriorly beyond the anterior margin of the upper jaw. The lower jaw joint is located at the level of the midlength of the orbit. The dentary is relatively low. The dentary teeth seem to be similar to those of the upper jaw. There are eight branchiostegal rays. The vertebral column consists of approximately 47 (12 abdominal plus 35 caudal) vertebrae. The vertebral centra are rectangular, longer than high, becoming smaller and more elongate posteriorly. The five posterior abdominal vertebrae bear large and approximately triangular parapophyses with distally pointed tips (Fig. 6A). Pointed dorsal prezygapophyses are well-developed throughout the vertebral column, whereas ventral prezygapophyses solely characterize the caudal centra (Fig. 6B, C). There are about seven pairs of ribs, of which the posterior rib is associated with the penultimate abdominal vertebra (Fig. 6A). Fragments of intermuscular bones are also preserved; however, their original number and relative position is difficult to interpret. The median fins and their internal supports are only partially preserved. The caudal fin and its skeletal support are not preserved. The preserved portion of the dorsal fin originates above the seventh or eighth abdominal vertebra, although it seems to be slightly displaced from its original position. About 50 dorsal-fin rays can be recognized, although their original number was certainly higher. The size and limits of the anal fin can be recognized, but due to inadequate preservation it is not possible to interpret the actual number of anal-fin rays and the morphology and configuration of the anal-fin pterygiophores. The dorsal-fin rays appear to be longer than their opposite anal-fin rays. The pectoral fin contains about 17 elongated rays that extend posteriorly beyond the tenth abdominal vertebra. The structure of the pectoral girdle is unclear. The pelvic fins are thoracic and contain two filamentous rays. The basipterygia are not recognizable. Thin and small cycloid scales are preserved in caudal region of the body (at the level of the vertebrae 20th to 23th).” Identified by T. Přikryl (Institute of Geology, Academy of Sciences of the Czech Republic) as Propteridium sp. References: Fahay, M. P.

  4. The spikefishes are related to the pufferfishes and triggerfishes. Taxonomy according to GBIF. Diagnosis after Tyler et al., 1993: "Carpathospinosus differs from all other Triacanthodidae by the first dorsal spine with a longer average relative length (37% SL versus 24%-34%) and the second dorsal spine considerably shorter, with an average relative length at the low end of the range of length in other triacanthodids (15% SL versus 13%—29% SL), its length contained an average of 2.4 times in the length of the first spine (versus length of second spine contained an average of 1.1-1.4 times in length of first spine in Recent triacanthodids and 1.8 times in the Oligocene Prohollardia). Carpathospinosus differs from all other Triacanthodinae by the presence of an anteromedial flange on the first basal pterygiophore of the anal fin (versus flange absent); the pelvic spine much longer than the length of the posterior process of the pelvis, the process contained about 1.5 times in the length of the spine (versus pelvic spine usually shorter but sometimes as long as or very slightly longer than the process, the process contained about 0.8 to 1.1, usually 1.0, times in the length of the spine); the head especially long, about 45% SL (versus averages of 35%—41 % SL except in the two long-snouted genera). The relative width of the pelvis in Carpathospinosus is greater than in any other triacanthodin except the Recent Bathyphylax." Line drawing from Tyler et al., 1993: Identified by oilshale.

    Isurichthys cf. roumanus

    Identified by A. Bannikov, Borissiak Paleontological Institute, Russian Academy of Sciences. According to A. F. Bannikov, the first record of the species Isurichthys in the Polish Carpathian Mountains. From the Jamna Dolna II section, which is an artificial exposure about 2 km south of the original Jamna Dolna exposure. Diagnosis from A. F. Bannikov (2012): "Body slightly elongated, its depth equal to, or greater than, head length. Head 0.34–0.29 of body length. Supraoccipital crest high. Jaw teeth small, uniserial. Vertebrae 28–31 in number, including 16–19 caudal vertebrae; parapophyses present on posterior abdominal vertebrae. Neural spines very slender. Ribs relatively long, absent on haemal spine of first caudal vertebra. Spinous part of dorsal fin with 8–12 spines, soft part with 15–18 widely spaced rays. In anal fin, 15–16 rays also widely spaced. About three anterior interhaemals entering abdominal cavity, their dorsal ends closely positioned. Pectoral fins long, usually reaching origin of anal fin. Pelvic fins moderately long. Caudal fin large, deeply forked. Scales large,cycloid."

    New Jurassic site

    Hello, I made this trip actually yet in 2020, on December 29th, but I didn't have time to post it earlier. I went to Sulejów, which is a former limestone mine now flooded with water: Nearby there is an active mine, but they don't let in fossil hunters Anyway, I was hoping that the water level would be low enough to permit browsing the slopes and it was so - of course not in every place. Some parts of the reservoir are overgrown and not very accessible: There were however a few slopes where I could go closer to the water level and browse the rocks:
  15. Kasia

    What is it?

    Hello, These are fossils I found during my recent visit to the Pleistocene site. Any idea which animal it could belong to?
  16. Kasia

    Could this be wood?

    Hello Everyone, today I went again to my favourite Pleistocene site - and a friend of mine found something that he thinks could be a fossilised wood. He thinks it could have been brought here by the glacier. It looks like this: It's not very big, as you can see - but quite heavy. Does this look like wood to you? I will appreciate your feedback.

    New Miocene site

    Hello everyone, two weeks ago I went for a short fossil hunting trip - first a Devonian location, which I believe I have already presented, then the Silurian one - also reported before. The last place was a Miocene site that I have never visited before. It's called Smerdyna and is referred to locally as a "little grand canyon" As you can see on the map, it streches for more than 3 km - it's like a huge crack in the middle of flat land: From the ground level it looks like this:
  18. Hi everyone, I'm new here and I hope I can find identification with the help of this forum, I don't know much about fossil, I'm interested in everything that's old and in history in general. This summer my 5y old son found the attached bone(?) at a beach in Poland (city of Sopot) and i didn't thought much about it. Yesterday I used Google lense and it displayed other similar bones of raptor(?) Toe bones. Maybe you guys know more about it, i thank you in advance for your help. My son is super interested in dinosaur of course and i try to give him as much knowledge about History as possible. Have a nice day and stay healthy Scale is in Centimeters
  19. Hi, as recently I have been going mainly to the Pleistocene location, I have lots of surplus fossils I will gladly trade I'm not looking for anything specific - all offers are welcome. Set A Set B Set C Set D All these fossils come from Góra Kalwaria, Poland.

    Fish Aspirations!

    One of the rarest and most unique fossils are aspiration pieces! I have been very lucky in acquiring 2 over the course of collecting, neither are incredibly good, but their rarity alone makes them that much more desirable! I would love to see anyone else's fish with eyes bigger than their stomachs!

    shell in flint

    Erratic boulder found in Poland so no geological context, but I'm guessing Cretaceous circa about ;-) Can you identify this species? Maybe Lopha sp.?
  23. Gen. et sp. indet.

    unknown shell

    I find the ribbing of this shell peculiar. Do you recognize this taxon? Oxfordian of Poland. Associated finds include: sponges, brachiopods & bivalves.
