       Aviatyrannis was for lack of a better word tiny,‭ ‬although this small size is actually a hallmark of tyrannosaur ancestry.‭ ‬Although incomplete,‭ ‬the fossil remains of Aviatyrannis are very similar to another ancient tyrannosaur,‭ ‬Stokesosaurus,‭ ‬from North America.‭ ‬This has resulted in speculation that‭ ‬Aviatyrannis‭ ‬is actually a junior synonym of Stokesosaurus,‭ ‬and further fossil material may reveal the answer once and for all.‭ ‬Regardless of what may happen with the genus of Aviatyrannis in the future,‭ ‬the fossils from Portugal do prove that the early tyrannosaurs did find their way to Europe,‭ ‬probably from North America.‭ ‬This in turn goes some way to explaining the presence of Eotyrannus,‭ ‬a later tyrannosaur from the early Cretaceous that was discovered in the British Isle's.
