Otoliths can be quite good indicators of fish species and even the age of the fish. Looks like there are at least 4 otoliths so at least two individuals. Each ring should be a period of growth, correct? Thicker are time of plenty. That should be interesting to look at. How would one tell the species through the otoliths? “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...

I'd say that's a pretty good candidate for coprolite (or regurtitalite). Was the age mentioned? Link to comment Share on other sites More sharing options...

It looks like it definitely came out one end of something.

Can't wait to see what you found if you are going to post. I went to the museum and the pit across the road back in 2004. I drove there on the Autobahn for the first time in a fairly crappy hatchback. It struggled to get much over 130 km/h. I would love to return with someone who knows what they are doing.

I would love to return with someone who knows what they are doing. As usual, I forgot my camera My goal was to help the kids have a good time and they were pleased as punch with all the nice little gold ammos they found. I wasn't in it for myself this time around, since I actually have enough of this ammonite material in my collection anyway. It would have been nice to have spotted some Ichthyosaurier bits, but they're few and far between there and I saw no signs of them yesterday. Our member @belemniten knows his way around the shale pit Schieferbruch Kromer very well and often comes up with teeth and vertebra, so maybe he'd be happy to show you around if you happen to come over again.

belemniten Posted August 15, 2017 Share Posted August 15, 2017 Nice to hear that your kids found some nice ammonites in Holzmaden ! But I think that you caught a bad time to visit Holzmaden. I suppose that you visit the quarry Kromer? They don't have much material now .... The best chance to find teeth and bones is in the "Schlacke". This is a layer with lots of fish parts so it's relatively easy to see. You can let me know @Doctor Mud , if you visit the area again. Otherwise you can always ask the people, who "keep an eye" on the quarry. But I think we shouldn't deviate too much from the original topic. Whatever it is, it's a nice find ! Many greetings from Germany ! Have a great time with many fossils Regards Sebastian Link to comment Share on other sites More sharing options...

Sorry for the late response. I was out looking for poop in Nordakota! I agree with Carl. The picture is a little fuzzy, so I can't tell which it is. If it is mostly a pile of undigested goodies, I'd say it is more likely a regurtitalite. If there is a good amount of homogeneous, nongranular material included, I would lean more toward coprolite. Super cool either way! Lori www.areallycrappystory.com/fossils www.facebook.com/fossilpoo Link to comment Share on other sites More sharing options...
