Clearly little known is that a Kimmeridge Clay (Kimmeridgian, Upper 
Jurassic) ornithomimosaur was reported by Clarke and Brokenshire a 
few years ago. The material (from Dorset) is unimpressive: two 
manual phalanges, one of which is an ungual. Identification is suspect - 
- nevertheless (err, excepting _Shuvosaurus_) it is the oldest reported 
ornithomimosaur.
