"I think it's possible that when we were butchering our prey, the smell of blood attracted that Tyrannosaurus. Apex predators like that have a keen sense of smell. I bet it could identify the scent of the female Tyrannosaurus," Wang Yun analyzed. "Chief, I suspect this Tyrannosaurus is a male—probably the father of those eggs in the nest."
Li Yue asked, puzzled, "Then why wasn't it living with the female Tyrannosaurus?"
Wang Yun said, "In the animal kingdom, females of some species drive away the males after they become pregnant or give birth. This is because some male animals might engage in 'infanticide,' a behavior that's especially common when food is scarce and living space is limited.
"In an environment like the Gobi Desert where prey is scarce, every additional adult Tyrannosaurus is another competitor. This is particularly true for older Tyrannosaurs that can't compete with younger ones. So, that might be why the female drove the male away."
