    Hi Everyone, I found this fossilized tooth-like specimen in Poland (Kraków area, mydlniki quary) probably Jurassic layers. I will be grateful for helping me with it's identification. Thanks .
  2. Hi all! As winter is getting nearer I tried to catch the last glimpses of summer and went for a one-day trip to the Volga river, taking advantage of unusually low water level and a good weather forecast combination. And I wasn't disappointed with scenery and finds, which I'd like to share with you. Last warm days of November before snow cover:
  3. Hi everyone, I got a theropod tooth in Madagascar recently, but I can't clearly know what it is. Any idea about the id? Thnaks! M serration 6/mm D serration 6/mm CH 14.5mm cbl 6mm cbw 4.5mm M serrations extend to the base(I can see under the micro view but can't take a clear photo sadly) also a little fold near the m side surface of the crown. Location is: Near Kamoro river, Madagascar Isalo III fm seller is 100% sure from Jurassic period
  4. Hi, again please let me know if this is not a genuine Grallator footprint. It's from Languedoc Rousslion France and Lower Jurassic. Again thanks to all for the help. I won't be buying impulsively again.

    Pseudorhina alifera Muenster 1843

    From the album: Vertebrates

    Pseudorhina alifera Muenster 1843 Late Jurassic Tithonian Sappenfeld Bavaria Germany
  6. From the album: Vertebrates

    Aspidorhynchus acutirostris (Blainville, 1818) Late Jurassic Kimmeridgian (late) - Tithonian (early) Painten Formation Painten Bavaria Germany This fish lies in an extremely soft rock and was very difficult to prepare. At the slightest touch (even with a small brush) scales could come off. Unfortunately the top of the skull is slightly dislocated.

  10. This piece is supposedly a horseshoe crab ( Mesolimulus walchii) from the Solnhofen limestone of Germany. It is Jurassic and the description says there has only been mild color enhancement. Is this fossil real? Any fabrication? Thanks for the answers!

    Solnhofen Brittle Star

    Hello everyone, and I hope you've had a good weekend. I have purchased this brittle star found in the Solnhofen Limestone. Here are the two images they have provided - in any case, they're probably higher quality than my phone would be able to take. They have labelled it as an unidentified species, and that it is known to have grown to a maximum of 3 centimeters across. The slab my specimen is on is 3 cm itself. What should I label it as in my display cabinet? Thanks for the help, it has been much appreciated over the last few weeks.

    Jurassic print ?

    Hi, i've taken this near the Jurassic Pterosaur beach in the Department Lot, France. The item is 2 cm at the longent part. On the pièces i"ve taken there are dessication traces and calcite. On one of them i have a partial print and on another i have fossilized rain drops. I wondered if that shape could be the print of a little tridactyl animal which used its heel to walk or if it is geologic. Here it is seen in different angles and with a skirting Light.
  15. In my opinion, the black colour and the good state of the inner whorls give a more elegant touch to this fossil. I still dont know what type of rock are but its amazing
