Ptilophyllum is an extinct form genus of leaves belonging to the extinct seed plant order Bennettitales. The leaves, like other Bennettitales morphogenera are generally pinnate. Leaves possibly attributable to the genus are known from the Oligocene of Australia, which may be the last known representatives of the order.{{Cite journal|last1=McLoughlin|first1=Stephen|last2=Carpenter|first2=Raymond J.|last3=Pott|first3=Christian|date=2011|title=Ptilophyllum muelleri (Ettingsh.) comb. nov. from the Oligocene of Australia: Last of the Bennettitales?|url=https://www.journals.uchicago.edu/doi/full/10.1086/658920|journal=International Journal of Plant Sciences|volume=172|issue=4|pages=574–585|doi=10.1086/658920|s2cid=52885618 |issn=1058-5893}}
