izak_ Posted November 15, 2017 Share Posted November 15, 2017 G'day, We recently found this partial placoderm skull at a property near Wee Jasper, NSW and I'm wondering what part of the skull it is. We found a lot of other stuff on that trip too, and I'll do a trip report on that eventually. Thanks, Izak Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted November 15, 2017 Share Posted November 15, 2017 Nice find I should state I have zero knowledge of such things, but could that be the top of the head? I think I see eye sockets to the left and right of the first picture for example? 1 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
fifbrindacier Posted November 15, 2017 Share Posted November 15, 2017 Hi, i can't see the tags, so i don't know if you have given the age of it. Could you tell me ? I don't see a skull in this although i'm not an expert, but this is really a nice and big placoderm. Neat find, i'm eager to see your other finds. 1 "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux."

Miocene_Mason Posted November 15, 2017 Share Posted November 15, 2017 Awesome find! was it found this month? Maybe VFOTM.. 1 “...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...

FossilDAWG Posted November 15, 2017 Share Posted November 15, 2017 Is this from the Gogo area where Devonian fish occur in concretions? Don Link to comment Share on other sites More sharing options...

FossilDAWG Posted November 15, 2017 Share Posted November 15, 2017 Sorry, I didn't mean to imply you were raiding a protected site, just curious if there is any faunal relationship. A lot of work has been done on the Gogo fauna and that could perhaps help ID your material if there is any correlation. Don Link to comment Share on other sites More sharing options...
izak_ Posted November 15, 2017 Author Share Posted November 15, 2017 No worries. I'm not sure if much work has been done on this site, not even sure what formation it is :/ Link to comment Share on other sites More sharing options...

jdp Posted November 16, 2017 Share Posted November 16, 2017 Seems to compare reasonably well with Edgellaspis, known from Wee Jasper. Link to comment Share on other sites More sharing options...
