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- 10 replies

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

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 unsure about lizard identification because their ribs are rounded in cross section and narrow in all the length. Please suggest any ideas, all 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.

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
