Good evening everyone! Few days ago I found this bone fraction on the southern shore of Dusia lake, Lazdijai district, South Lithuania. The maximum thickness is 6 mm, the thick layers and bone canals are also well visible. There were three times when I noticed very similar bone pieces in fluvial sandstone boulders of Siauliai district (Northern Lithuania) too. By me some limb bone cross sections of theropod dinosaurs look similar but I need professional ID of this bone taxonomy- I am sure it belongs to tetrapod, probably reptile or less likely mammal. Any opinion will be

unidentified teleost scales, please help with families of fishes
D.N.FossilmanLithuania posted a topic in Fossil ID
Dear researchers, I was collecting these scales and bones of teleost fishes in flint erratic boulders of South Lithuania 1-4 years ago and I still do not know which fish families these several strange finds belong to. The other remains are identified and judging by that taxa I think the majority of these fossils are from recent families. The flint origin is deep sea or ocean so some strange taxons like fangtooth, lanternfish or other can be possible. If here is an ichthyologist who knows more about recent fish scales, I would be very happy to get an answer. The scales are 2. -
Dear Guys, Few months ago I found this specific skull part in Varena town, South Lithuania. It is 4 mm diameter and the central line is protuberant, I would think it is something like squamosal or quadrate, it was inside dolomite erratic boulder. Please help to know which part of skull is this and maybe which animal this bone could belong to. Best Regards Domas

Chimaeroid tooth from Lithuanian erratic boulder with better picture quality
D.N.FossilmanLithuania posted a topic in Fossil ID
Dear Guys, I recently made better pictures of chimaeroid tooth fossil, I think this remain belongs to Psephodontidae family but maybe I am wrong so I need the professional ID. This chimaeroid shows the Late Paleozoic (Carboniferous or Permian) age of some lagoonal dolomite erratic boulders in Lithuanian territory but if someone knows the genus of this chimaeroid remain then I could know the precise age of the erratic (stage or epoch) and could use this find in my scientific articles to German magazine. The remain is 4-5 mm length so the tooth is small. Please help to kn -
Dear Guys, I recently found this thick perforated chimaeroid like fossil in lagoonal dolomite, it is 5 mm length. It is found in erratic boulder of Varena town, South Lithuania. The perforations in Tremataspis scales are the same thickness in all surface but my find has much thicker perforations by the one edge and I would think it is dental plate of chimaera. The fossil is thin but I saw the gastropod fauna in these dolomites and some species can speak about Carboniferous- Permian age although very similar dolomites in Northern Estonia are Silurian in age and they also have o

Dear Guys, Several years ago I found this piece of fin spine that is 3.5 mm width and by me it looks more similar to primitive shark like Onchus problematic fossils. Here is visible vertical groove texture and also oblique area of little oblong tubercles. The fossil is found in Late Silurian limestone erratic, the location was Varena town, South Lithuania. Please help me to know, is it more like acanthodian or Onchus chondrichthyan? Best Regards Domas

Dear Guys, I found this 2 mm length lizard osteoderm in small dolomite erratic about 1 year ago in Varena town, South Lithuania. It has some rounded tubercles, by me seems quite similar to helodermatid. I think the age is probably Cretaceous or Paleogene. Please help to identify family by its shape and ornamentation. Any help will be appreciated! Best Regards Domas

Dear Guys, I recently found one rectangular tooth plate or osteoderm like fossil with tenuous canals and even poorly visible rough pointy texture in one area, it is 5 mm length. From the first impression it looks more like osteichthyan tooth or tetrapod osteoderm, it is found in pink dolomite erratic. I had versions about stingray or Lagarodus chimaera earlier but shark teeth always have thicker ornamentation like thick canals, glossy porous dentine and many canals in root especially talking about chimaeras, the stingray tooth elements have parallel grooves and tu

Eriptychiid agnathans from Baltic??
D.N.FossilmanLithuania posted a topic in General Fossil Discussion
Good evening everyone! I have found these two fossils (scale and epitegium) in the dolomite erratics of South Lithuania, Varena district. The scale has very big and long tuberculae (unlike well known Oniscolepis with serrated and small pattern of tubercles), the size of scale is 8 mm length and the tubercles are up to 1 mm width. The same tubercle pattern (massive, oblong and not serrated) have primitive pteraspidomorphs like Eriptychius. The second find (epitegium) is quite small, about 5 mm length and it has leaf/spine like tubercles without serration, very similar to- 3 replies

Dear Guys, Few months ago when I still was in Varena town I found this tiny osteoderm (probably lizard) in dolomite erratic with some other remains. By rough surface texture the fossil looks similar to Helodermatid but lizards consist of many families... Please help to identify this remain to know the age for sure, I would think it should be from Paleogene. Any help will be appreciated! Best Regards Domas

hammerhead shark tooth? Species and age would be helpful
D.N.FossilmanLithuania posted a topic in Fossil ID
Dear Guys, Few months ago I found this tooth in mollusc matrix of Varena town, South Lithuania. Judging by growing orientation, I think it could be from Hammerhead shark but maybe someone could identify more accurate? Any help will be appreciated! Best Regards Domas -
Better pictures of possible dinosaurian teeth from flints of Lithuania
D.N.FossilmanLithuania posted a topic in Fossil ID
Dear Guys, I recently photographed these small reptile teeth with maximum contrast and got quite good pictures. They are already sent to dinosaur specialist but until I wait for an answer I would like to dicuss about these finds judging by better picture qualities. The first tooth from three sides (2.7 mm length): -
Please help to confirm bird beak elements found in flint erratics of Lithuania
D.N.FossilmanLithuania posted a topic in Fossil ID
Dear Guys, I recently found many possible beak parts in flint erratics- three premaxillas, one maxilla with teeth, one culminicorn and one latericorn. The age of flint erratics in my area is Late Cretaceous- Paleocene. If there are any specialist who work with bird bones, please help to confirm this identification. The remains are found in Varena town, South Lithuania (The Baltic Region). Best Regards Domas -
Dear Guys, I recently found these teleost scales in flint erratics, they are between 3 and 6 mm length. The location is Varena otwn, South Lithuania (the Baltic region), flint erratics in our area are usually Late Cretaceous or Paleocene in age. the scale with brush like top has many point like surface elements in middle and upper part, only in bottom it has growth lines or circuli. Please help to identify some orgers or families of these fish remains. Any help will be appreciated! Best Regards Domas

Dear Guys, I recently prepared one bigger tooth I have found in flint erratic, it is 1 cm length, crimson and little curved with blunt upper end unusual to shark. The edges are little serrated but I wouldn't expect dinosaur. However, I think it is also not from bony fish and the serrations look more reptile like. Plesiosaurs and elasmosaurs have quite rounded cross section in teeth, so maybe it is from Pachyvaranus, etc.? Any idea what is this? Best Regards Domas

Good evening Guys, Today I splitted some flint erratics in gravel and except some fish remains founde this tooth. It is straight in sculpture, 5 mm length, serrated edges are not visible and its vertical groove texture is irregular what makes me think it does not represent fish. I would say it is baby mosasaur or very small mosasaur species, but I want to find out which taxon would be the most correct for this find. If you see features typical to known reptile or other vertebrate group, please let me know. Any help will be appreciated! Best Regards Domas

Good evening everyone! I checked the flint vertebrate collection at home, prepared two ribs by needle and look for possible ID in the internet. The both ribs are 7-8 mm length, curved and quite short that lets me to think they are lumbar or last thoracic (around pelvic girdle). I know that fishes also have ribs but they are not so rounded in the cross section and much less curved I think, fish ribs are even very narrow. I would say that the feature of flet rib edges could origin from cynodont reptiles (their ribs even have leaf like bodies). I am also very u

Late Jurassic foraminiferans, please help with ID
D.N.FossilmanLithuania posted a topic in Fossil ID
Dear Guys, I recently collected many skeletons of foraminiferans (sarcodine protozoans) in glauconite spongiolite erratics that I think are Kimmeridgian (Late Jurassic) age and I very need your ideas! Many fossils consist of lagenids, small rotaliids, textulariids and etc. I am sure these forms are almost all benthic. In the same erratics I found sea urchin spines, sponges, worm tracks and especially mollusc/ vertebrate fauna. The skeletons are from 0,3 mm diameter to 15 mm length, very various. Please share your ideas about identification here or recommend a speci -
Dear Guys, Today found one erratic in gravel and when I splited it I found this leaf like imprint. It is 3 cm length. By the shape I would say it is from big clubmoss but I very need more opinions, maybe it is possible to identify genus or family? Any help will be appreciated! Best Regards Domas

Skull fragment with tusk like cavity- the second elephantid?
D.N.FossilmanLithuania posted a topic in Fossil ID
Dear Guys, Today I found one very interesting piece of skull, as I remember I have showed you one non- mammoth elephant skull fragment that was between 1,5 and 3,2 cm thickness. Today's fossil is very similar fragment, also with brain surface but it has one cavity that reminds me of tusk place. This skull fragment also have some cavities but very few, and it is little thinner (between 0,9 cm and 2,3 cm thickness (it is thicker in the place of possible tusk). I would think it is also from rare elephantid or maybe hippo (because it is thinner)? Please help with ID of -
Dear Guys, Yesterday I found the small but very thick skull bone fraction with brain imprint preserved, it is between 1,5 and 3,2 cm thick and 6 cm length. I have seen the central line in frontal bone that is visible in mammal skull but my find has quite massive ridge near central head line that is visible in the side of fragment. I would think it can belong to mammoth but I am not completely sure. Judging by small anatomy and thickness of bone, what it might be? Best Regards Domas

Dear Guys, Today I found the lower articular piece of big femur, the length of articular end surface is 13 cm. It is very similar to bison but judging by size I think it could belong to hippopotamus. I also checked wooly rhino but there are some differences in the articular surface. Any idea what it might be? Best Regards Domas

Dear Guys, I found this 17 cm length bone fragment in the sand dune layers of Varena town, there was the building site where the sand was deeply mixed up with younger layers. Judging by the shape, I think the most correct version should be bear (the tibial plateau is separated and not found). The last brown bear (Ursus arctos) in Lithuanian territory was hunted in 1885 but the tibia is quite big and maybe there are more features that could differ from present bear that is known is the European and Russian forests. Please help to confirm Ursidae family by this bone an

Dear Guys, I recently found the triangle bone in dolomite erratic of Varena town, South Lithuania, it is 4 mm length. It has the wider growths in the lower sides and straight blunt bony growth in the top. The dolomite also has poorly visible calcified lenses (maybe oncolites?). The erratic is typical to Triassic arid conditions and should belong to Late Triassic epoch because frogs from Early Triassic are found only in Madagascar island.
