That makes very little sense, seeing that they have a common ancestor with birds.
I do not see how their brain would effect the look of their eyes, not to mention, their brains were not more lizard-like. Achrosaurs are in no way related to squamates, in fact, they are almost as distantly related to lizards as we are.
1. Archaeologists, do not dig up dinosaurs, palaeontologists do.
2. No, they are not related to lizards at all. Lizards are squamates, in the order squamata, tyrannosaurus rex is a dinosaur, in the order archosauria. Birds ARE dinosaurs, and are far more closely related to T.rex than any lizard.
