Rich & Vickers-Rich, 1994 ti-MIEM-us

Combines the name Tim (honoring both Timothy Rich, son of the discoverers, and paleontologist Tim Flannery) with Latin mimus ('mimic'), meaning 'Tim's mimic'

113.2–100.5 million years ago Albian, Early Cretaceous
Early Cretaceous stages

Timimus is a genus of small coelurosaurian theropod dinosaur from the Early Cretaceous of Australia. It was originally identified as an ornithomimosaur, but now it is thought to be a different kind of theropod, possibly a tyrannosauroid.

Under dispute

Timimus hermani was named by Rich and Vickers-Rich (1994) on an isolated femur and referred to Ornithomimosauria; its affinities have since been questioned, with a tyrannosauroid placement among the alternatives proposed. The single-element holotype is too fragmentary to resolve this.

Diagnosis

  1. Femur lacking an intercondylar groove on the extensor (anterior) surface
