Albertavenator (meaning "Alberta hunter") is a genus of small troodontid theropod dinosaur, known from the early Maastrichtian in the Cretaceous period. It contains a single species, A. curriei, named after paleontologist Phil Currie, based on a partial left frontal found in the Horseshoe Canyon Formation of Alberta during the 1990s.[1][2] Albertavenator's discovery indicates that small dinosaur diversity may be underestimated at present due to the difficulty in identifying species from fragmentary remains.[3]
