Australian Placoderm

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.

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?

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.:D

Neat find!

Just now, FossilDAWG said:

Is this from the Gogo area where Devonian fish occur in concretions?

No, Gogo is a protected site.

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.
