Bones discussion.

[BOD]

More on the bear.

Earlier first find pics.

 

[Hairyman]

Anyone like to speculate on what species this jaw belongs to and what may have contributed to its death?
Found near a creek in the Southburnett in SEQld. Length 70mm.

Bandicoot???

 

[survivalist]

looks like an omnivore but i'm not sure since i'm not in that area.

This one has really thrown me, at first it looks dog/fox like but those rear teeth aren't right at all.

 

[Hairyman]

Bandicoot???

Spot on, Isoodon macrourus (Northern Brown Bandicoot) http://bushcraftoz.com/forums/showthread.php?1464-Isoodon-macrourus-(Northern-Brown-Bandicoot)
see my pic in post #5 in that thread.
@ Survivalist, yes they are omnivorous.
@ Phrayzar, too small at 70mm to be a dog or fox but the unusual appearance of the rear teeth is due to extreme wear, right down to the roots,
so this may have contributed to its death and probably indicates old age.

This bone is from a young Eastern grey kangaroo, you can tell its still young by the way the ends are not yet fused into one
continuous solid bone, this is were growing/lengthening takes place. This bone is relatively fresh, not yet bleached by the sun, about 2
months since death.

I found these bones on a beach in the whitsundays. At first I thought turtle but it doesn't fit with any pictures of the species up there. The vent like structures are very strange indeed. What do you think Hairy and the rest of you clever BCOZ people.

Heres another two close up at other angles

 

[Mozzie]

Very light and air rated bone, I'm wondering if thats the keel bone of a bird? Maybe a pelican?

 

[Greatbloke]

Wow, that's an interesting looking one. Part of it looks like a birds breast bone, but the rest is just weird.

 

[Hairyman]

Probably a partial skull of a large fish, a hump head wrasse perhaps.

Mozzie "Very light and air rated bone, I'm wondering if thats the keel bone of a bird? Maybe a pelican?"

That's right Mozzie, it has the density of a bird and the size is right for something like a Pelican but the fused vents and some of the other joints are way off as far as my knowledge goes.

Greatbloke "Part of it looks like a birds breast bone, but the rest is just weird."

Ha ha thats what I think. When I found it I was looking at it for ages until my friend came over and said "what the hell are you looking at ?" I said "you tell me", he couldn't.:risatonaD:

Great, now we are on track. Thanks Hairy.

:_applauso: Stellar work there my friend. If you look at this shot minus some of the left point it's almost the same.


This is the site that shot came from. A new one for me and looks great. http://www.skullsunlimited.com/index_skullmaster.php

 

[Mozzie]

fish, well there you go, you know I REALLY like this "pick up a bone and identify for me"

had me puzzled thats for sure, it was the density of the bone that had me thinking bird

humphead wrasse...awesome fish, shame to find a skull of one :-(

Me too Mozzie, CSI for the bushies. Yeah I hope it died of natural causes.

 

[Hairyman]

Pathology in a red-necked wallaby jaw, possibly a disease know as lumpy jaw, often caused by the soil bacterium Fusobacterium necrophorous.

 

[Hairyman]

A bandicoot lower left jaw, there are regular looking scratches on the bottom that could be goanna teeth marks.
