<<<  |..Labrosaurus >>>

<This is generally regarded as a synonym of _Allosaurus_. The type 
specimen is a partially crushed and plastered up dentary with what 
appears to be some kind of pathology at the front end (as if the front 
end had been bitten off). The teeth strongly resemble those of 
_Allosaurus_, and it might even belong to the well-known _Allosaurus_ 
skeleton that's mounted at the Smithsonian, which is from the same 
quarry and is mounted with a mandible from a different and somewhat 
larger individual.>

I pratically agree. Being parsimonious about it. But Labro is generally 
listed as junior to *A. fragilis*. I believe there is more similarity 
with *A. atrox*, who does appear separate at the species level from *A. 
fragilis*.
