    Russian fossil sites

    Hi all In this topic I'll give a brief overview of Russian fossil sites and typical fossils. I focus on the Jurassic as my main field of interest. The method used here is analyzing regional and temporary breakdowns of the number of specimens, shown by amateurs on Russian fossil resources, mainly ammonit.ru (about 40.000 finds). Unfortunately the overview has a inevitable bias towards the sites and fossil types attractive to the largest number of amateurs and downgrades those that are remote, less popular or less productive. The material is presented from an amateur's point of
  5. Hi all! Those who follow my reports know I was planning another trip to Ulyanovsk in spring. Well, here is the report, in continuation of 1, 2 and 3. This time I was on the shore for 3 days. In short, the weather was fine, the ice abundant, the competition high and the finds scarce. The trip felt more like an extravagant outing than a productive fossil hunt
  6. Von Mayer originally described this chimaera under the name Ischyodus avitus. Elasmodectes avitus, a cartilaginous fish, is conspicuous for its sparsely ossified skeleton. There is a nuchal spine behind the head; the dorsal fin begins just behind the nuchal spine and extends to the tail. Elasmodectes seems to have possessed a skin or only very thin scales, which seems to be almost impossible to preserve. The Skull is presenting its dosal view. Reverence: WOODWARD, A.S.

    Agathis jurassica White, 1981

    One of the common coniferous plant fossils found at the Talbragar site is Agathis jurassica. The genus Agathis is extant, representing a small group of some 21 species mainly distributed in Australasia, belonging to the same family (Araucariaceae) as Wollemia. Together with a fishtail. Key references: White. M.E., 1981a. Fish beds reveal lush fossil forest. Australian Natural History 20 (7), 227-230. White. M.E., 1981b.

  10. Hi all! I was finally able to visit the Volga site thanks to a water level/ good weather window. The journey was mostly a success, I got a better understanding of the site, used new means of transportation and examined more of the shoreline. Among the finds were two dozens of marine reptile verts and bone fragments and LOTS of ammonites and other mollusks. Unfortunately the river level was not low enough, 1m higher than during my 1st trip, 0,5m lower than in the 2nd. But it was at least possible to walk the shore. There's still a lot more to do, but now I have a pretty clear idea how to m
  11. Hi, I'm considering this partial ichthyosaur jaw with 5 teeth (3 in a natural position and 2 others that have been displaced--one is on top and one is on the backside) from Jurassic (Tithonian) deposits in Tartarstan, Russia. The seller, who is also the finder/preparer, has identified this as Undorosaurus and noted that there is repair to the last tooth at the end, which broke and has been glued back together, and some holes that he filled in on that tooth--these are shown in the second photo with the red line (repaired break) and circles (filled in holes), as drawn by seller--but

  13. Three species of Thylacocephala have been described from the Solnhofen Formation (“Solnhofen lithographic limestones”) so far: Clausocaris lithographica, Dollocaris michelorum, and Mayrocaris bucculata. A fourth new genus and species was newly described in 2019: Falcatacaris bastelbergeri.

    Jurassic fish (?) tooth for ID

    Hi, what do you think of this tooth? It's of round section (at the base), has carinae, rooted probably. Possible ID: Eutrichiurides, Lepisosteus or maybe something like croc? Middle Tithonian, Jurassic, Moscow, Russia (marine environment). 7 mm length. Provenance is not crucial, IMHO, if you have something similar, for example, from Dorset, please let me know. "frontal" view round base "side view", carinae a "head" is visible here, it was probably the part that stuck out of the jaw view from
  15. Hi all! Following the first topic I'll show you another fossil layer in that same location, Epivirgatites nikitini ammonite zone. It's the lowest of the three layers in Fili Park, relates to the middle Tithonian (Volgian, upper Jurassic) and is known for big ammonites and vertebrate remains. It's the last remaining accessible site in the region where you can count on finding Jurassic vertebrates. The finds are stable, but small, scarce and involve sifting.

    Gyrodus circularis Agassiz, 1844

    The genus Gyrodus is a characteristic faunal element of Late Jurassic marine environments and includes the largest known pycnodont (G. circularis, Upper Jurassic of southern Germany). Most pycnodonts are small to medium sized fishes with a standard body length of some 25 cm or less. Only a few large forms with a standard body length of more than 50 cm are known. Gyrodus circularis is the largest pycnodont with a standard body length up to 200 cm (KRIWET & SCHMITZ 2005). Literature: L. Agassiz. 1843. Recherches Sur Les Poissons Fossiles. Tome I (livr. 18).

  17. Since the summer of 2007, the Jura Museum Eichstätt has maintained a scientific research excavation in the Ettling limestone quarry (Markt Pförring). For a long time, this limestone quarry was considered almost fossil-empty, until private collectors discovered a number of exceptionally well-preserved specimens. The Ettlingen site yielded numerous species previously unknown in the rest of the Plattenkalk region. The fish are very difficult to prepare - the preparation is done under the microscope purely mechanically by scraping only with fine needles and scalpels. The last two pictures ar

    Coccoderma nudum REIS, 1888

    Around Solnhofen at least four species of coelacanth have been recorded: Coccoderma nudum REIS 1888, Holophagus penicillata EGERTON 1861, Libys superbus ZITTEL & REIS 1888 and Macropoma willemoesii VETTER 1881 Coccoderma nudum is the smallest of these 4 species with barely more than 30cm.

  22. Hi everybody! Today I’ll show you yet another distinct fossil hunting location within the city limits. It’s situated in the south-east in the direct vicinity of the Moscow ring road (city and regional border). The outcrops are located on the banks of the shallow Shmelovka (Shmelyevka) river, effectively a small fordable creek.

  25. ...Down to Gorky( Brateyevsky) park... Hi all! It is time to introduce you to the famous Panderi zone of the Moscow fossils. It is named after Dorsoplanites panderi ammonite (middle Volgian/Tithonian, Upper Jurassic), which in turn got its name from Heinz Christian Pander. It consists of numerous cast iron-like (black, heavy, solid but fragile) separate concretions containing mostly ammonites and bivalves. The fossils from the Panderi layer are grim, black, rough and depressive (in line with this winter).The zone is present throughout Moscow but becomes most accessible in the
