PSchleis Posted January 25, 2020 Share Posted January 25, 2020 I thought maybe some kind of steinkern, but part of it is pitted like bone marrow. It doesn't resemble anything else I've found. It's pinched at the top. The top pinched end is smooth and shiny - almost enamel-like. The bottom half is round and pitted. 1 Link to comment Share on other sites More sharing options...

Mahnmut Posted January 26, 2020 Share Posted January 26, 2020 In your other thread pyroclastic bombs have been mentioned. thefossilforum.com/index.php?/topic/101877-is-this-bone-and-if-so-big-enough-to-tell-what-it-is/ I think in this case it is a rather nice one, showing signs of oriented flight like in some meteorites and tectites. The smooth side would have been leading.

Mahnmut Posted January 26, 2020 Share Posted January 26, 2020 I cannot be sure, but that is my impression. Is there known volcanic material in your region? Nowadays there is of course always the possibility of slag, but it looks like it flew, that seems to me to be a good sign. and as for tilly bones I couldn´t say. I have only ever found one fresh (still fishy) one while on holiday, never a fossil. They don´t occur where I live. The one I have is quite solid, not like spongiosa at all.

Best regards, J I have many tilly bones, so confident this isn't one. But I don't know about whether volcanic material should be here. Gonna research that. I do still like your imagery of what might have happened Anyway, thanks for offering your thoughts! Link to comment Share on other sites More sharing options...
Boesse Posted January 27, 2020 Share Posted January 27, 2020 I'm actually about 90% sure this is the posterior process off of a dolphin tympanic bulla (earbone) - a much more complete modern bottlenose dolphin for comparison. These things frequently break off of the rest of the bulla, and would approximate that shape/texture if waterworn a bit. 4 Link to comment Share on other sites More sharing options...

I can see the similarities, especially if you break it off and erode it quite a bit. Link to comment Share on other sites More sharing options...
