  2. Tyrannosaurid tooth

    It's amazing how a fossil can be scanned and uploaded like that. Now everyone can see the fossil in 3D.

    Indeed! Lovely.

  6. Brachiopoda

    Always good to see a nice brachiopod!
  7. Brachiopoda

    196.5-182 ma.
  8. Vitta picta (Férussac, 1823)

    Yes, these are fossils, as DPS already pointed out, about 15 million years old (we don´t have a coast in Styria (yet)). According to www.fossilworks.org, this species went extinct 12.7 million years ago (similar info on www.marinespecies.org - extinct). And yes, they belong to the family neritidae. But maybe, these fossil shells belong to a still extant Vitta species?? I don´t know. Franz Bernhard
  9. Vitta picta (Férussac, 1823)

    These are fossils because they are 14 to 16 million years old even if they look like living forms. A fossil is usually defined as any trace of the body of an organism or trace made by the organism that is at least 10,000 years old. The preservation can range from nearly unchanged original condition to completely peeudomorphed by another type of mineral or rock.
  10. Vitta picta (Férussac, 1823)

    These aren't fossils, are they? They're exactly like modern nerite or nassarius snails. Ive had lots in my tanks over the years.
  11. Vitta picta (Férussac, 1823)

    You are welcome! Yes, they are! ...and the smallest gastro species is the prettiest . Franz Bernhard
  12. Vitta picta (Férussac, 1823)

    Wow! Those are exquisitely decorated!
  13. Vitta picta (Férussac, 1823)

    I had no previous knowledge of these gastropods existing! Thanks for a very interesting post.
  14. Vitta picta (Férussac, 1823)

    Very nice! Thanks for the photo and the link! Could they be at least belong to the same genus?? Thanks! I already know you like them . I have sent you a pm.
  15. Vitta picta (Férussac, 1823)

    Can you add a few more photos, from a single, complete specimen, as shown HERE ? As a virtual museum, we like to be able to see all distinguishing details.
  16. Vitta picta (Férussac, 1823)

    Here is a photo of the Florida species I was thinking of. (source: https://glpolites.wordpress.com/2010/10/15/farley-creek-small-gastropods-excluding-cerithiidae/). Don
  17. Vitta picta (Férussac, 1823)

    Yes, they are nice, indeed! But soooo small... Franz Bernhard
  18. Vitta picta (Férussac, 1823)

    Amazing color patterns! It reminds me of a species I have collected from the Miocene Chipola Formation in Florida, though I do not remember the species off the top of my head. Don
  19. Vitta picta (Férussac, 1823)

    Second photo: About 50 individuals of the snail Vitta picta in different states of weathering, but most of them are still glossy and show their color patterns. The gloss is natural, no coating or something else applied, only washed. The color pattern is strongly variable between individuals. Note that also the outline is quite variable, which is typical for this species. Field of view is 40 mm, largest gastropod is about 6 mm high, so this snails are really small. This is a "multi-genus-species" and was/is assigned also to the following genera: Theodoxus, Agapilia, Clithon, Nerita, Neritina. According to Fossilworks, this species was an epifaunal omnivore-grazer and went extinct 12.7 million years ago. First photo is perhaps the largest and one of the best preserved gastropods of this lot in two views. Height is about 6 mm. It is not perfectly preserved; some parts of the outer shell layer, and hence the color pattern, is missing in the right view. Some parts of the shell along the aperture on the right side are also missing. Outline is quite typical, somewhere in the middle between nearly globular and somewhat cylindrical with a constriction in the middle. Exact locality is Höllerkogel-21 in my own documentation. This relatively large outcrop contains predominately the mud snail, Granulolabium bicinctum, and V. picta. Unfortunatelly, most of the shells are strongly weathered or even completely dissolved. Höllerkogel-21 is about 5 m stratigraphically higher then Höllerkogel-18 and located just upslope of Höllerkogel-18. The sediments in the area belong to the "Florianer Schichten", which are part of the western Styrian basin at the eastern margin of the Alps. The "Florianer Schichten" are about 15 Ma old (Langhian, or "Badenian" in Paratethys stratigraphic terms). x

  21. Dickinsonia costata Sprigg, 1947

    I just saw these things today. Purty dang cool! and really good lookin considering their age! Ron
  22. Dickinsonia costata Sprigg, 1947

    What a neat specimen! Did you see today the article that they found fossil fat molecules on a specimen? http://science.sciencemag.org/content/361/6408/1246 Regards, Chris
