The diversity of Devonian- Early Carboniferous lungfish teeth in Lithuanian erratics, free to discuss!
D.N.FossilmanLithuania posted a topic in Fossil IDDear Guys, I recently got a new camera and made the better pictures of all my lungfish dental plates. There are some families identified but I would be very happy to discuss with you about unidentified specimens and features of each dental plate, maybe some of you would know genera of these finds? The age of fossils is Devonian- Early Carboniferous, they are found in Lithuanian erratics (the majority in marine dolomite and some in shallow marine sandstone). The smallest find is 1,5 mm length and the largest is 1,2 cm length. Please tell your opinion about identifications of these finds, any help will be very appreciated because it would be great material for publication The first fossils I show are holodipterid dental plates. The main feature- merged tooth rows with poorly visible odontodes in the top. 4-7 mm length.
D.N.FossilmanLithuania posted a topic in Member CollectionsDear Guys, I found this fossil in the July 21, 2017 in Varena town, South Lithuania (it is Southern part of Baltic States). The genus of this lungfish is Ctenodus, sp-ecies are not identified. Its age is from Svete horizon to Klykoliai series (Late Famennian- Lower Tournaisian). This genus is still not found in the Lithuania and Baltic States, my find in dolomite erratic is the first dicovery in this region. The length of fossil is 6 mm. Please vote for this fossil if you are interested. Best Regards Domas
Good morning everyone! I have collected many vertebrate fossils from Tournaisien dolomites, Carboniferous marls and Early Carboniferous- Permian carbonated sandstones. I tried to identify the age of the erratics for a very long time and I think that all three types of erratics are from Carboniferous or Permian periods. There are many rhizodonts, megalichthyids, lungfish dental plates, one ganoid scale, small shark tooth and even one big ptyctodontid placoderm tooth (I have doubt if it is more famennian like or could be Tournaisien). In the same Tournaisien dolomites I have found many crinoids, brachiopods and molluscs. From brachiopods the Productids, spiriferids, rhynchonellids are very numerous, there are also some athyridids and Orthotetes specimens. In the marls the clam shrimp remains are often, plant (like horsetail) remains are very rare, the majority of fishes are rhizodonts and there is also one specimen of two skull bones from small amphibian. Please help to confirm vertebrate fragments (especially Sagenodus lower jaw and Ctenodus upper jaw plates), for the age confirmation I also will show invertebrates if it is needed. Best Regards Domas
