Allosaurus or Tyrannosaurus toe bone fossil?

[Agos1221]

Hi all,

 

Recent find in an old collection. It appears to be a theropod fossil toe bone but I cannot tell what genus or species, or formation. I don’t want to jump to conclusions so I’m putting it out there to all you good people to help hive mind an answer. Thanks!

Without a provenance and its poor preservation going to be difficult.  Can you post a side image of the  phalanx, both sides. There are lots more theropods out there that would fit that size.

 

Edit is the second photo a top view?

[Agos1221]

Understood and sure. 

I think like this you mean? 

[Troodon]

Thanks

Very odd preservation.

It does have the appearance of a Tyrannosaurid Left pes Digit IV Phalanx 1 .   But having said that without a provenance there are multiple Tyrannosaurids it could be or other theropod.

Thanks, Troodon!

I was wondering if the pitting on the bone is disease? I found the preservation unusual too.

I dont know if it disease or preservation.  The latter possibly because several of your photos like this one appears to be below the outer layer..
