Odd shaped bone?

[Ash]

Anyone have any idea what bone this is? Never found one like it before. Pleistocene of Australia.

 

 

[GeschWhat]

Not my area of expertise, but the shape reminds me of a giant bony fish vertebra.

Looks marine. Skull element of some sort? Possible brain case of marine reptile or fish.....

 

Edit: It resembles a fish vert, but i don't think it is.

That is strange looking. I’m curious to find out what it is.

I would also suggest a very big fish vertebra.

May we have a pic from the top down and the bottom? Meaning the vertebral body serface. 

You’ve provided a few side shots, but they’re from and angle so a straight on view of the dorsal side or the side where the pedicle of the lamina attach to the vertebra, the side with the spineous process may be helpful.

Vertebra from the neck will look very different from those of the tailbone area or middle back. So pics from the top down give a lot of info.

The diagram may be helpful.

The last pic looks like the dorsal side of the vertebra where the pedicle was once attached.

I am not sure which fish may have produced this vertebra.  Compare generally with this one:

I don't think this is a fish vertebra. Keep in mind that if it is a fish vert, it would have been a freshwater fish.

Also, I'm not really seeing any big resemblance to a fish vertebra here, it is mammalian.

Could it be the proximal end of a scapula ? 

The texture doesn't look fishy to me either.

Could you explain why this would have to be ?

It's from over 180 kms inland(correct me if I'm wrong), and would have been even further from the ocean during the Pleistocene, so would have to be from a freshwater system (not saying that distance from the ocean always means freshwater). There are other reasons such as fauna that indicate a freshwater system though, like certain fish and freshwater bivalves.

Ah ! 

Unrecognized context.

Looking at the little socket here, could it be a snake vertebra?

Lori's guess reminds me that there was a giant varanid in the Pleistocene of OZ.  Megalania or Varanus priscus.  I don't know much about varanid vertebrae.  Anyone?

 

 

[Tidgy's Dad]

They're sort of cross shaped 

Even without the processes it doesn't look a match to me.

I'll get up the requested pics tommorow morning with access to better internet. Thanks guys.

[Ash]

Fresh new pics. Hope these help.

Thanks guys and gals.

Interesting find, not my area but I get the feel of something around the pelvic area. So waiting for a positive ID.

Ash you could send images to the Queensland museum via there website.

I'll be going back down there soon so will take it then.
