Alioramus was one of the smaller tyrannosaurids to have arisen and thrived during the Late Cretaceous period. Mind you, the only known specimens thus far are juveniles and subadults, so just how big an adult could grow to be is unknown. Along with Qianzhousaurus, it appears to be part of a distinct branch of the tyrannosaur family.
By now, I think it truly is safe and reasonable to say that Mattel has done better with the Jurassic Park license than any other company. Granted, outshining Hasbro was hardly difficult given what a substandard job they did, but what about Kenner? They may no longer around, but back in the glory days of the 1990s, they bestowed on us collectors a slew of awesome dinosaur toys, plus humans and vehicles if you were into that sort of thing (I never was).
