Hell Creek Dinosaur Tail Vertebrae id help Struthiomimus?

[jikohr]

Hi all!

Lovely little something I acquired recently. Seller said Struthiomimus, just wanted to verify and see if anyone could provide insight on differentiating altus from sedens from potentially something else like Anzu, raptor, or Tyrannosaur. Measures 7.5 cm tall, 7 cm long, 3.8 and 4.2 cm wide centrums.

Found in powder River County Montana. Was apparently found "crushed" and then repaired.

I have no hard comparative material nor publications to definitively make a call other than photos.  Here is a string of Struthie vertebrae for use as a comparison and you can see the similarity

Oh wow, that is dead on! Mine seems to be a little further down the tail than these.

Are altus and sedens both still valid species for Hell Creek Struthiomimus?

Hell Creek/Lance:  S. sedens

S. altus older deposits
