Tomasz Posted August 16, 2020 Share Posted August 16, 2020 All, I have got a strange looking osteostracan fish from Stjordalen Fm, Spitzbergen. It is Emsian. It is not identified but generally belongs to the elongated type of osteostarcan fish from that locality. As you can see it shows that a part of the exterior headshield layer is missing showing probably a viscelar/internal structures. Maybe it is an effect of predation or just a mechanical damage during formation of the fossil. Nevertheless, it is interesting. Pictures are not of the best quality but some internal structures seem to be visible. It is a strange looking one. Any comments or suggestions are very welcomed. Thanks, Tomasz 3 Link to comment Share on other sites More sharing options...
marumo Posted August 16, 2020 Share Posted August 16, 2020 Really interesting specimen! Was the fossil exposed in the field, or did you have to put in some work to expose it? Link to comment Share on other sites More sharing options...

jdp Posted August 17, 2020 Share Posted August 17, 2020 Huh. Can you get me a closeup of the bone texture where the dermal skeleton hasn't been completely lost? Link to comment Share on other sites More sharing options...

jdp Posted December 20, 2022 Share Posted December 20, 2022 Ah sorry, hadn't seen those. Hard to say since the surfaces are pretty weathered. I'll check some stuff here in January if you remind me. 1 Link to comment Share on other sites More sharing options...
