what type of bone

[RockNerd4Life]

It stuck to my tongue, so I know it's bone, I'm just not sure what part of the body or the kind of animal.

Looks like a notta bone to me.

 

But seriously, this appears to just be a slightly bone shaped rock nodule to me. And the fact that it stuck you your tongue doesn't mean anything, especially since most fossils shouldn't be sticking to your tongue (obviously can vary depending on the preservation). But yeah, that isn't indicative. Some minerals stick to the tongue and some don't, some fossils do and some don't (and I'd say more don't which would make that a point against fossil if anything)

I think the sticking to the tongue test is more a test for a sticky tongue.

Just about any rock that is porous will produce a bit of suction for the tongue. Just plain physics.  The bone lick test puts me in mind of the fallacy of the undistributed middle: 

 

1) Some cheeses have holes 

2) Some rocks have holes

/Therefore, some cheeses are rocks.  

 

1. (Ex) (C > H)

2. (Ex) (R > H)

/ (Ex) (C > R). [we note here that "holes" appearing in the premises does not appear in the conclusion]

Please do not lick rocks. 

 

Sticking to your tongue just indicates something is porous. Porosity is a feature of bone, as well as many rocks.

Not a definitive test of anything, really, and definitely not of fossils.
