Long Cycads
Like their lumbering grazers, most cycads have gone extinct. Their disappearance from their prior habitats began during the late Mesozoic and continued into the early Cenozoic Era, punctuated by the cataclysmic asteroid impact and volcanic activity that mark the KPg boundary 66 million years ago. However, unlike the dinosaurs, somehow a few groups of cycads survived to the present.
