Is this a real T-Rex tooth

[Eva213]

My father was a geologist. I found this in his stuff. On the bottom it says “tyrannosaur Rex Tooth from the largest specimen ever found. University of Calif., Berkeley 1977. Is this real or fake?

Most likely a cast replica. I see loads of these for sale online, all replicas. It's still a really cool cast of a HUGE T-Rex tooth!

Thanks. Any way to tell for Sure?

[PaleoRon]

It is a reproduction.

Brighter pictures, with something like a ruler for scale, and images taken of the root and the serrations (if any)

[Eva213]

Will post more pictures in sunlight tomorrow. Thanks

Bounce it gently in the palm of your hand. Which word comes to your mind - light or heavy?

[Eva213]

Heavey but it’s on a base and the base weights more than the “tooth” part.

If it were a resin cast, you could heat a needle, and push it into the tooth.

 

I took the liberty of brightening your photos.

More detailed photos, showing any serrations that may be present would be helpful, though.

The top of the tooth looks cracked to me. I know it’s too dark. Will get daylight pics tomorrow. 

[Eva213]

Will try the needle thing. Thanks so much!

Hi. I’m almost certain this is a cast/replica. I did a quick search and actually found a few replica teeth that were almost exact duplicates of the tooth in your photos right down to the shape of the base. Still I’d investigate it further. @Troodon

The replicas I have encountered are "light," subjectively. That is, they just do not feel as weighty as a solid tooth. If it were mine, I would now try pushing a heated needle into the base. If it's resin, the needle should melt/penetrate. That leads thought to the "bottom" of the object. In at least one picture, it seems suspiciously flat. What does the base look like? Is it textured and "bone-like"?  The flat bottom just gives the impression it was cast to stand-up as a display.

The closest match comes from amazon ... the mold looks like it is getting a bit soft or has/was recast several times.....

Like the others have said, it's a cast replica. Still a nice piece though. Good for educational uses and such.

[Pemphix]

+1 for cast.

This is the most obvious proof to me that this is a cast.

Yup, I have seen the exact same replica on some sites. So sorry, it’s a replica. But still a nice one.

[Troodon]

Replica seen many of these for sale....largest trex tooth  found  you can read info on locality where it was found.

[JarrodB]

Cool old replica. 

[Eva213]

Thanks every one!!!! You are right. Hot needle went right through. 

[Jaimin013]

It is a replica without a shadow of a doubt
