Dear Guys, Recently I write the book in the Microsoft Word document and collect evidences about all bony fish and tetrapod pieces I have found and recently I want to show some teleost fish remains found in flint erratics that speak about very young age of some flints that can be found in gravel of Lithuania. Some fish remains (I do not speak about that appeared in Cretaceous or Paleocene- Eocene) belong to fish taxa that is very young and appeared in Oligocene, Miocene or even Pliocene age. It is the such fauna as slickheads (Oligocene- recent), mulets (Miocene- recent), Salmon like fishes (in Europe they lived from Miocene), triplefins (Miocene- recent), dory fishes (foun only in Oligocene fossil record), pikes (Oligocene- recent), Minnows (most typical to Neogene and Quarternary), gobies (in Europe live from Oligocene to recent) and the genus Atherinomorus (fossil record is known only in Pliocene of Jamaica). These remains show that flint erratics in Lithuania are much younger than previously thought! The main fossils of fishes are scales and I will share the links into evidence of each group and its temporal range. At first I will show slickheads (Alepocephalidae family).

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, Yesterday I found three pterosaur teeth in flint erratics- one big (9 mm length) and two small (~ 3 mm length). German scientist Daniela Schwarz identified them as pterosaur remains. I checked their features by binocular- they have the same oblique serration but smaller teeth differs by one feature: ine the upper crown end in one side they are more curved and have broken up contour of the edge. The surface of teeth is the same- very small crevice like ornamentation. Judging by this material, these features make me think that it is the same pterosaur family or genus and the teeth probably are from different mouth parts. The age of Lithuanian flint erratics are Late Cretaceous- Paleocene so these teeth can be from End of Cretaceous and belong to last toothed pterosaurs! If you have quite much knowledge in pterosaur teeth, please help me to find out the narrow taxon which these pterosaur teeth should belong to. This is the first case of their fossils in Lithuania and I am sure these teeth are from the same reptile. Any help will be very appreciated, you are welcome to discuss! Best Regards Domas

Dear Guys, Today I prepped out the scraps of two bones in flint and also have another completely preserved. The first bone cavity in the picture belongs to frog clavicle and coracoid block in my opinion, the second cavity is scapula like and the third bone is scapula like complete fossil example. The scapula like bones are very tiny- they are only 3 mm length, the coracoid/clavicle block is 4,5 mm length. The remains are found several years ago in Varena town and Barciai village (varena district), South Lithuania, the Baltic States. Please help to confirm or identify frog bone block and especially help with ID of scapula like remains. I can tell that there are not visible joints in scapula like bones and the both specimens are from different sides. Any ideas? Best Regards Domas

Dear Guys, I have found three coracoid bones in flintstone that are about 0,5 cm length and made the cavities of them by needle. There are two versions about these fossil ID in my opinion- enantiornithine bird or pterosaur (pterosaur is more possible because the lower wider part of bones is not very wide as in almost all birds and the pterosaur, e.g. ornithocheiridae coracoid shape is very similar!). If these are pterosaur coracoid bones they should belong to small species (maybe rhamphorhynchoids), if small bird bones- they should be very primitive, probably early Cretaceous and I do not know any birds with this shape except Enantiophoenix (Enantiophoenix coracoid is even little wider and the bone cavity is very small, not so big as in my specimens). Please help to identify these remains by the coracoid form in pterosaurs, primitive birds or even tiny dinosaurs. Any help will be appreciated! Best Regards Domas
