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 appreciated! Best Regards Domas

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 2.5- 9 mm length, pointy skull bones are from 5 mm to 1 cm length. Best Regards, Domas-
- two scales are pointy in surface
- paleocene- pliocene (??)

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

Dear Guys, I recently found this flat tooth like remain in Devonian fluvial sandstone erratic, it is 6.5 mm length. I think it is some kind of placoderm but I very need the professional opinion. Order or family of this tooth would be very helpful! It is found in Varena town, South Lithuania. 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 know the taxonomy of this remain if someone works on Paleozoic sharks here. Any help will be very appreciated!- 9 replies

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 orthogastropod and bivalve fauna. Please let me know- is it osteostracan scale or is it chimaeroid tooth, and what species are the most possible then? Any help will be appreciated! Best Regards Domas

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 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 tuberculae that are very thick in appearance. I also saw some osteichthyan teeth- puffer fish dental elements are triangular in shape and only one tooth in Darwin county page from Jurassic was the same in shape (but not in surface texture!) and was named as "shellfish eating fish tooth" with no taxonomic determination. The tetrapods like reptiles also have some similar osteoderms- rauisuchians and other primitive archosaurs or maybe lizards but crocodile related osteoderms have the web of tuberculae with oblong and deep pits between it and lizard osteoderms in my opinion should not be so protuberant in the central area like my find. This fossil talking about shorter edges in the ends is low and it becomes tall in thickness in the center including the same central part of longer lateral boundaries. I told everything about the features of fossil I found, I actually do not know its age because it was found in small erratic boulder of dolomite. Dolomite in the prequarternary surface of Baltic States is usually Devonian, Permian or Triassic but I even have confirmation of polygonal lizard scutes in dolomite so the age would be known if I would find out which taxon this skeleton element belongs to. Pleasehelp me to know about the taxon of this remain and also- tooth or osteoderm it is? Any help will be very appreciated! 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

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 Anatolepis from Norway (the leaf like tubercles are visible) or maybe the same Eriptychius (in some body areas it also has short, almost rounded tubercles). In the same erratic with epitegium fossil I noticed the poorly preserved piece of trilobite jaw. Please check some information about Eriptychius and Anatolepis remains from Ordovician and let me know if I can think that my finds are Ordovician in age... Any help will be appreciated!
