Australian Placoderm

Recommended Posts

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

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.

No worries. I'm not sure if much work has been done on this site, not even sure what formation it is :/

Seems to compare reasonably well with Edgellaspis, known from Wee Jasper.
