"poekilopleuron" is a genus of theropod with a long and complex history. the genus was first named and described by jacques-amand eudes-deslongchamps in a report published in 1836, based on holotype material that is now destroyed. in 1837, eudes-deslongchamps published a more detailed account of this discovery in a monograph which was also inserted next year in volume 6 of the "mémoires de la société linnéenne normandie".
