Greetings to everyone! After a long absence, I came back with some interesting fossil material. Location: Western Bulgaria ~30Kms away from Sofia Age: Carboniferous - Westphalian Formation: Svoge I have visited the place one more time with no success, seeking within the banks of a small creek. Maybe my eye was not trained at identifying fossils within black shale and coal, or I was just not looking at the right spot. Last weekend, the weather was really sunny and pleasant, after 2 weeks of rain so I took Sara and hit the road! I stopped at a spot I could tell there was black shale and this time I climbed a quite steep slope, instead of going again into the creek. I was lucky and within minutes, I found my first Paleozoic plant material. That felt good! Having visited the local museum very recently, I was able to identify some Calamites sp. This was my first find, a decent chunk of Calamites. This one, I believe it is Lepidodendron sp. but not obovatum as per the species exhibited in the museum. Or maybe it is quite eroded. What do you think? The last fossil I collected was a multilayer with Calamites sp. , max dimensions 30X20cm. It was heavy, I have found enough so I called it a day. You can see the rest of the pictures at the bottom, more or less the same. I found a publication here http://www.bgd.bg/REVIEW_BGS/REVIEW_BGD_2006/pdf_files_2006/06.pdf which does not mention Lepidodendron at all. The fossils were cleaned with water, toothbrush and some soap to remove all the dust caused by the coal. I may visit again the formation, since I read some other reports that seeds of Carboniferous can be found there, plus some Devonian(?) Graptolites close to this place, so there is still some interest. Hope you like the findings!

I've spent some time gathering at the plant layer locally. I was able to pry behind the layered shale and pull out some larger pieces unbroken, and also split them. The layer is a delight, just about any piece I recover has some sort of plant impression on it. Immediately below the layered shale there is a more nodular type of rock that no longer breaks apart in neat and tidy planes. So whatever environmental change happened, it happened right at this layer. The first one was a really long and well defined fern frond. The carbon is all still in place. I want to create a parallel cut to remove this part of the specimen, then catalog and store it. I am hoping I can do so in a way that won't dust over the carbon and degrade it. The rock that covered this was a physical impression of these leaves in the rock. It appears more could be exposed at the bottom, but it's not easy to do. The second specimen is a preserved fern frond with very tiny leaves. The larger leaves stick out, but a more complete arrangement like this is very pleasing to look at. The iron staining at the bottom creates almost a work of art. This specimen has a small root or similar structure at the bottom right of the photo. There are repeating points towards the bottom with larger circular structures at the top. These huge fern leaves showed up right before I was done searching during this particular session. Both sides are shown. It would be interesting to know if it continues on in the other direction.

I'm getting better with plants, but I haven't really found anything that says seed or spore pod to me. This one finally does. It's a small depression with texture. I wish I had the other side, but I didn't see it. This was from a layer with many ferns, Calamites, and Cordaites. Concretions are about non-existent here. In fact, there may be none at all. It's the texture in the depression that has me thinking seed pod mold.

Location: n-e Italy. Probably Permian or Carboniferous. It's a fossil? Algae?

Taxonomy according to Mickle et al., 2009. The University of Montana, UM Paleontology Center website (Browse Collections - College of Humanities and Sciences / UM Paleontology Center - University Of Montana (umt.edu)) lists "Yogoniscus gulo" as an old taxon on some specimens (but not on all specimens) of Beagiascus pulcherrimus. Obviously, confusion has occurred. Diagnosis from Mickle et al., p. 639: “A lower actinopterygian fish defined by the following combination of characters: elongate fusiform body, narrow in cross section; premaxillae narrowly sutured in midline; nasal notched anteriorly and posteriorly; posterodorsal process of antorbital forms base of posterior nasal notch; frontal with a sinuous sagittal suture; crescent-shaped dermosphenotic; large dermopterotic with a wide posterior plate, laterally spurred, anteromedial process situated within a notch in the frontal; three large suborbitals situated within curve of preoperculum, small fourth suborbital overlapping large suborbital, suborbital between posteroventral infraorbital and maxilla; four infraorbitals – narrow infraorbital ventral to orbit, crescent-shaped posteroventral infraorbital, an intervening element, and T-shaped posterodorsal infraorbital, tapered anterior end of posterodorsal infraorbital comes in contact with tapered posterior end of nasal; mosaic of several small bones in curve of posterodorsal infraorbital for spiracular bone; long maxillary plate; two rows of pointed, posteriorly inclined teeth down length of maxilla; prominent posteroventral process of maxilla; anteriorly inclined hatchet shaped preoperculum; one row of 5 or 6 anteopercular bones along anterior margin of operculum – ventral-most anteopercular bone wider and longer than the others; rectangular, anteriorly inclined operculum with transverse ganoine ridges; rhombic suboperculum with vertical ganoine ridges; total of 14 or 15 branchiostegal rays – five above mandibular corner, 9 or 10 at and below mandibular corner, first branchiostegal twice as high as second; anterior and posterior extrascapular rows sharing median extrascapular (anterior row – three lateral bones, posterior-single bone bearing supratemporal commissure); unsutured postspiracular; one row of rhombic postcleithral scales; narrow ventrolateral flank scales; f ank scales finely pectinated; fan-like pectoral fin; triangular pelvic fin, triangular dorsal and anal fins with posterior edges tapering off gradually; heterocercal caudal fin deeply forked, accessory flap on epicaudal lobe; all fins bear long, stout, overlapping fringing fulcra on leading edges; precaudal ridge scales continuous between the anal and caudal, and dorsal and caudal fins. Meristic, morphometric, and cranial measurements are presented in Tables 9 to 12.” Line drawing from Mickle et al., 2009, p. 642: ID by oilshale using Mickle et al., 2009. Reference: Mickle, K. E., Lund, R. and Grogan. E. D. (2009): Three new palaeoniscoid fishes from the Bear Gulch limestone (Serpukhovian, Mississippian) of Montana (USA) and the relationships of lower actinopterygians.

Hi,Could anyone help with this?It was found in Scotland close to a large fossilised Lepidodendron tree.Thank you
-
Since they are so common, I don't keep many coprolites unless I notice they have interesting inclusions. This is one of the more interesting inclusions I've found to date. It measures maybe 2mm in length. I believe it is the branchiopod Pemphilimnadiopsis ortoni (what a name!), and was hoping for a second opinion. @deutscheben, I know you've found some of these before. Any thoughts are appreciated.

Howdy! This specimen comes from the Pennsylvanian Period, Conemaugh Group, Glenshaw Formation, in the Mason Shales below Brush Creek Limestone. The area has a lot of Pecopteroids, Neuropteroids and Calamites. However, I've been informed that it is not Calamites. I should also note that this piece was part of a larger fossil cast that was crumbling apart when I found it, and unfortunately, I was unable to save the rest of it. The last picture is the back side. All help is appreciated and thanks in advance!

Hi all, I've had this Mazon Creek fossil in my collection for a few years now. It is labelled as a Tully Monster, and seems to match up with other Tully Monster fossils I've seen on the forum and online, but I am by no means an expert, so I would appreciate any help with confirming the ID!

Hi. The geological info for this find is: Pennsylvanian (Carboniferous), Conemaugh Group, Glenshaw Formation. I've been digging at an outcrop near a local stream and finding a lot of pecopteroids, neuropteroids, calamites, some sphenopteroids and possibly lepidodendron/stigmaria, sigillaria and cordaites. Recently the rain washed away the dirt at the base of this outcrop. Cutting away the rock at the base I found at least a dozen instances of these somewhat cylindrical and flat-topped and flat-bottomed rocks sitting one on top of the other. The first picture shows a cavity from which I removed some of these rocks. I don't know if it helps, but there's a lot of iron in this area. Any ideas would be appreciated.

Here's a new find from the I&M trip last weekend. The nodule was full of indeterminate plant fragments, and I almost tossed it until this one small bit (~1cm in length) caught my eye. Maybe a wing fragment or am I being hopeful? The texture is much different than what I've seen in plants, but that's a bit hard to capture in pictures. I can try to get better pictures tomorrow in the sun if needed. As usual, any thoughts are much appreciated.
