Timimus is a little-known genus of dinosaurs from the Coelurosauria group . The name means "Tim's imitator" and is in the tradition that ornithomimosauria are often referred to as "imitators" ( mimus ) of birds. "Tim" alludes to both the son of the explorer couple and the biologist Tim Flannery . Only the type species T. hermani has been scientifically described and provisionally assigned to the ornithomimosauria . However, the few fossils of Timimus show no derived features ( synapomorphies ) of the group andnoevidence that he belongs to this group can be produced. Later, Timimus was classified as inenlagiiner Dromaeosauride as Oviraptoride or as Tyrannosauride . It must therefore belistedas a noun dubium .

Only individual thigh bones and fragmentary vertebrae of this dinosaur have been found so far . They belong to the type specimen NMV P186303 from the type locality Dinosaur Cove from the late Aptian and early Albian , so the late Cretaceous . The fossils are in the early Albian an age of around 113 bis 110 million years dated .
