I think that's how the book explains it- I remember a big section talking
about frog vision. Maybe you found a glich in the plot.
Now, why would a Deinoraptor (I like that, whoever I stole it from!)
differ so much from the rex as far as vision goes? Why would one theropod
"naturally" have frog sight and the other not? (Especially if the more
archaic one can see better!).
I could see it explained as Deinoraptors not having that frog gene.
