  1. Awesome Coprolite

    I just got an awesome coprolite. I generally hate those things, and would never pay money for one, but I came across this one and it has so many visible identifiable remains, I couldn't help being really impressed. Ive always wanted to see a coprolite that had clear remains in it. Sadly they're much smaller and harder to see in person than in these pictures, so I can only use these display pictures for the time being, until I take a magnified look. There's clearly fish scales, seemingly from different types of fish, and apparently squid hooks and such. I'm excited to find a good illuminated magnifying glass and really studying it up close:) Maybe even a microscope to take a closer look!
  2. Possible squid from Montour Fossil Pit

    I found this yesterday in my searches at the Montour fossil pit in Danville pa. I think it is a squid but wouldn’t mind help identifying it. The third picture is the opposite side of the rock. Thanks everyone!
  3. Ichthyosaur stomach contents

    From the album Marine reptiles and mammals

    Cross sections of the stomach, full of squid/cephalopod hooks and beaks, of an early Jurassic ichthyosaur (Stenopterygius quadriscissus). One slice has the animals ribs, the lighter tan objects, around the stomach, while the other is entirely of the stomach contents.
  4. Does anyone have, or have seen, small marine reptile's stomach contents? I'm specifying small because what I'm wondering about is of those that eat primarily and mostly squid. Ive been trying to find pictures, but I can't find anything thats close-up enough to see any details at all. Just like from a full picture of a full-body ichthy plate, which is way too far out to see the apparently stomach contents. *i don't mean corprolites, but actual impressions of the stomach contents
  5. Belemnite?

    This is a very recent find from the Cahaba River Valley. One person on the Facebook page identified this as a belemnite. Is this the general consensus? To my knowledge I have never seen one. I have a regular paper clip for size reference.
  6. Small Belemnite collection

    From the album Holzmaden fossils

    A few Belemnites I found. I am quite proud of the large piece even though it is not complete.
  7. Belemnite(unprepared)

    From the album Holzmaden fossils

    Another image of it from a top view
  8. Belemnite(unprepared)

    From the album Holzmaden fossils

    This is a Belemnite I found in Holzmaden, almost complete but missing the tip. I have not prepared it yet but quite a nice little fossil.
  9. Help Identify

    Hi folks. Been scratching my head over these for years now. Can find nothing similar through searching the web. A museum in Berkeley Springs, WV has loosely similar and call it squid, but not really close in appearance. The end of these are almost perfect taper and radiussed end, almost like machined. Some have a small stipple dead center on the rounded end. Some have shallow grooves but some (most) are as smooth as glass. A local suggested they were filled holes left by worms of sorts. Thanks for your time and attention. Regards, Rocky
  10. Hi all, a friend recently offered an interesting fossil to me - an octopus from Lebanon. Now, as some of you might know - Lebanon does have octopus fossils, though they are very rare. This fella here doesn't look outright fake at first glance, but I don't know if he's real either. I don't know many Lebanese experts, but when I showed it to two, here's what I was told. Expert A - It's real, but the tentacles are painted Expert B - It's just a squid painted to look like an octopus Now, painted tentacles is annoying, but at least it would be a real octopus. But a squid painted to look like one is a big no-no. What are your thoughts on this guy?
  11. Acanthoteuthis is now considered as a member of the Belemnoteuthida, a suborder of the Belemnitida. The ink sack suggests that this species lived not deeper than 200m. Lit.: Dirk Fuchs, Sigurd von Boletzky and Helmut Tischlinger (2010): New evidence of functional suckers in belemnoid coleoids (Cephalopoda) weakens support for the 'Neocoleoidea' concept.

  12. Estonioceras sp.

    Shell of an orthocone.
