Is this 100% authentic T-Rex bone

[Tyrannosaurus Rex]

Hello everybody,

 

I wanted to buy T-Rex bone for a long,long time,and today,I found one on online that has reasonable price for it's size.

I just want to know,is there any possible way for me to be 100% sure that it belonged to a real specimen of Tyrannosaurus Rex (not Daspletosaurus or some other dinosaur)?

I would like to get opinion from you,but I won't buy it if I won't be 100% sure it's from T-Rex.

Guy that sells them has 100% positive feedback on 96 sold items that are fossils.

Here are the photos:

As I said,I know it's hard to be absolute sure that this piece belonged to T-Rex,but I want to be as sure as possible.

Kind regards,

Petar

 

 

 

EDIT:just to be sure,I don't know much about fossilization,since I'm an amateur,except that when animal die it get buried by sediments and it degrades over time (soft tissue,collagen,organs...) and all is left is bones.But are those fossils from dinosaurs actual bones or just an imprint of what just to be a bone?

If I'm holding piece that belonged to some dinosaur,am I holding bone or just rock?

Sorry to say but will be impossible to narrow down a small portion of bone to a specific genus and species.

 

About fossilization, the bone proteins are degraded and are replaced by minerals in the rocks around it which leaves us with an impression of the bone which would make fossils rocks.

Posting photos directly here is preferable to third party sites that may vanish in time and render the thread moot. And some of us would prefer not to click on these sites to preserve our data autonomy.

Where does the seller say this bone was found, location and formation?  Agree with Kane an you post the pictures and not links

Thanks guys for help.Sorry for posting links,I tried to upload photos,but I could only upload up to 3,95MB,so that would mean 2 photos.

Anyway,seller said bone was found on Hell Creek formation.

Two options on photos, resize them or just include what you can then add the additional ones in the "submit reply"

 

On the bone looks like one from a herbivore like Triceratops but dont see anything that says 100% Trex.  Remember their bones are hollow so the insides are pretty smooth.  Only guarantee is that if it was collected with other known Trex material.
