Beyond the game
The real Eotyrannus
The reference specimen was juvenile or subadult and preserves parts of the skull and body. It was described in 2001 and expanded the record of early tyrannosauroids.
Its long, developed arms contrasted with the tiny arms of later tyrannosaurids. The known specimen had not yet completed its growth. Comparing it with large tyrannosaurids requires distinguishing differences in kinship from those that may be related to age.
This grouping describes evolutionary relationships. Its members share ancestors; they do not form a chain in which one must turn into another.
