Utah Vertebrae

[Allosaurus]

So I sorta impulse purchased these 4 little vertebrae from a rock shop (they were cheap, and looked like nice teaching specimens). They are from Utah, but have no further provenance than that. I am fully aware that complete identification of them is impossible without locality, but it would be great to even just get them down to a family. And heck if someone might have an idea on what formation they could have come from I'm all ears.

#1

#2

#3

And lastly, the partial caudal vert

[Troodon]

3 & 4 might be Croc if they the ends are concave on one side and convex on the other..

Unfortunately Utah is one of the most diverse localities in the world so without a provenance its pretty hard to ID centrums or know formation.   The chart shows 27 faunal levels and lots of dinosaurs

Yeah I figured it was a lomg shot. #4 is pretty partial so the end of the centrum is absent. #3 has concave ends on both sides.
