Dear Guys, I have found this bone fragment about 6 months ago and I am not sure which family of mammal it belongs to. It is the lower end of radius, to me looks like similar to carnivorous cat but I am not sure if it cannot be an ungulate. The length of piece is 9 cm. Please help to identify this bone. Any help will be appreciated! Best Regards Domas

Three unidentified tiny bones from Lithuania
D.N.FossilmanLithuania posted a topic in General Fossil Discussion
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

Pterosaur or Enantiornithine coracoids?
D.N.FossilmanLithuania posted a topic in General Fossil Discussion
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

Remains of sternum zone from lizards and frogs- please help to confirm
D.N.FossilmanLithuania posted a topic in Fossil ID
Dear Guys, Few days ago I found these three small bones in flint, they look like from sternum zone of small tetrapods. The triangle- like bone with three sharp growths looks like interclavicle (I would think it is from lizard), short bone with central hole looks like manubrium (the bone part near sternum common in amniotes) and the bone with two sharp gwoths below and blunt end in the top to me looks like frog omosternum. The fossils are found in flintstone erratics of Varena town, South Lithuania (the age is at most from Late Jurassic to Paleocene and the most common is Late Cretaceous). Here is the link to frog omosternum: http://schools-demo.clipart.com/search/close-up?oid=249075&q=sternum&s=1&a=c The link to lizard interclavicle: http://www.anoleannals.org/2015/01/15/geometric-morphometric-analysis-of-the-bsa-of-jamaican-anoles/ Second link to it: http://www.biologydiscussion.com/zoology/reptiles/reptiles-origin-history-and-classification/41033 (see fig. 8.57) https://pterosaurheresies.wordpress.com/2012/11/26/the-many-and-varied-origins-of-the-sternae-plural-of-sternum/ (see Saurosternon) And the picture of mammal? manubrium: Please help to confirm these fossils, they are important for my further research. Best Regards Domas

Dear Guys, I recently found two small scapula- like bones in flintstone erratics of Varena town, South Lithuania that are dated by Late Cretaceous- Paleocene age, the both are the same in shape and features so I think they are from the same narrow taxon but it is difficult to me to identify. Please ehlp with ID. Best Regards Domas

Please help with ID of sponges, corals and bryozoans
D.N.FossilmanLithuania posted a topic in Fossil ID
Dear Guys, I collected some interesting specimens in Jurassic- Early Cenozoic erratics like sponges, bryozoans and hexacorals and also two primitive Ordovician sponges. The sponge pieces are 3-8 mm length (In yellowish limestone on sponge has very interesting skeleton growth outside). The size of coral in greenish gray limestone is 9 mm diameter, in the white limestone- 7 mm diameter. The bryozoans are from 7 mm to 1 cm length, they web shaped. Please help with ID of these fossils if you could. Best Regards Domas 1. Late Jurassic sponges in my opinion. 2. Early Cretaceous (?) sponges. 3. Late Cretaceous- Paleocene sponges I think.

Late Cretaceous small tetrapods found in Lithuania
D.N.FossilmanLithuania posted a topic in Fossil ID
Dear Guys, I made the pictures of possible big discovery in Late Cretaceous erratics of Lithuania. There are some frog bones in flints (ilium, urostyle, tibiofibula, scapula), snake pieces (tibiofibula like of Tetrapodophis! and one thin scale), and toothed birs upper and lower jaw fossils. If you could confirm these finds, it will be the first further my article in scientific magazine and I wish it will be successful. There will be some posts, please review the pictures and tell what do you think. At first, I will show you frog remains. Best Regards Domas The second part- snake remains.

Dear Guys, Today I found one very interesting piece of bone, I think it is humerus of big carnivorous mammal like hyena. The size of bone is 10,3 cm length and 6,5 cm in the articular part. If it would be Cave hyena, it would be very rare find, my country belongs to Baltic States, Eastern Europe. The age of sand layers in my area is about 10- 13 thousand years. Please help with ID Best Regards Domas
