|Eotyrannus life reconstruction by Christopher DiPiazza.|
Eotyrannus was a tyrannosauroid which means that it belongs to the same group as large, two-fingered tyrannosaurids like Tyrannosaurus, Tarbosaurus, Lythronax, and Teratophoneus. Like them, it had curved, serrated teeth with a D-shaped cross section. However, Eotyrannus was more basal than these later predators and shares more in common with its closer, more basal relatives, like Dryptosaurus and Guanlong. Like them it had proportionally longer arms with three fingers on each hand, each tipped with a curved claw. It also had long legs and overall gracile build, implying that it was a fast runner.

When alive, Eotyrannus may have relied on its speed and probably specialized in hunting smaller prey, like the small ornithopod dinosaurs it shared its habitat with. It also would have needed to use its speed and agility to avoid the larger predators it coexisted with like Baryonyx, the spinosaurid, and Neovenator, the allosauroid.
