We report the observation of an unusual $B$ dependence of transversemagnetoresistance (MR) in the PrFeAsO, one of the parent compound of pnictidesuperconductors. Below the spin density wave transition, MR is large, positiveand increases with decreasing temperature. At low temperatures, MR increaseslinearly with $B$ up to 14 T. For $T$$\geq$40 K, MR vs $B$ curve develops aweak curvature in the low-field region which indicates a crossover from $B$linear to $B^2$ dependence as $B$$\rightarrow$0. The $B$ linear MR originatesfrom the Dirac cone states and has been explained by the quantum mechanicalmodel proposed by Abrikosov.
