Bennettitales (also known as cycadeoids) is an extinct order of seed plants.[1]

They first appeared in the Permian period and became extinct in most places toward the end of the Cretaceous. Bennettitales are among the most common Mesozoic seed plants. They looked like shrubs or cycads.

Although the leaves of the bennettitales looked like that of cycads, they had more complex flower-like reproductive organs. So some of them were probably pollinated by insects.[2]
