In mid-2008 he co-authored a paper that examined bone samples from a wide range of archosaurs, including early dinosaurs, and concluded that: Even the earliest archosauriformes may have been capable of very fast growth, which suggests they had fairly high metabolic rates.
Sredinom 2008. godine koautorirao je jedan rad u kojem su se ispitali primjerci kostiju raznih arhosaura, uključujući i rane dinosaure, i u kojem je zaključeno da: su čak i najraniji arhosauri možda bili u stanju brzo rasti, što ukazuje na to da su imali prilično visoku metaboličku stopu.
