Thump & Shriek are two Staurikosaurus and Torvus the Torvosaurus's minions (and rivals of Thud & Screech).
Physical traits[]
Staurikosaurus like them lack the sickle-claws found on dromaeosaurs and troodontids but are nevertheless just as dangerous.
Personalities[]
Thump & Shriek are just like Thud & Screech (even though they mostly resent comparisons): both duos are fiercely loyal to their big leader (in this case being Torvus).
