However, the size of their eyes relative to the size of their head is more typical of an animal that is active during the day. Dinosaur vision was, in general, better than the vision of most other reptiles, although vision varied between dinosaur species. According to his findings, while admitting that these were best-case scenario determinations, the T-Rex may well have had visual clarity up to 13 times better than a modern human.

The Implication, part 1: Where else do we see this "honeycomb" in a skeleton? They probably hunted Hadrosaurs and Triceratops. Even being able to see growth rings in limb bones was difficult, since these bones were constantly remodeled - this would have obliterated the evidence, if there ever was any.

Accuracy and availability may vary. Paleontologists know from the fossil record that, over millennia, T. rexs eyes got larger and its snout got lower and narrower, giving it even clearer sight lines than Stevens model. Did T. rex have color vision? The close relationship between theropods and birds has been hinted at since Richard Owen first noticed the honeycombing in three Megalosaurus vertebrae in 1856. It's also challenging for experts to determine the sex of the T. rex skeletons they dig up, leaving questions about differences between males and females unanswered as well. This dinosaur is best known for its large neck, which serves as sort of a counter balance for its long tail. As Zeus was to the Greeks, This gravitational lens was discovered by Dennis Walsh.

For the first time, scientists have discovered a way to identify the colors of extinct animals, including dinosaurs, through studying their fossils. They also had better depth perception than most other dinosaurs[citation needed].
