context_page_description: Cycadeoidea is an extinct genus of bennettitalean plants known from fossil finds in North America and Europe. They lived during the Jurassic and Cretaceous periods.
context_section_description: William Buckland originally gave the name to two species he described, C. megalophylla and C. microphylla, in 1828, seeing characteristics akin to living cycads. Robert Brown and Mr. Loddiges of Loddiges Nursery in Hackney had seen living cycads and urged him to name the fossils after them. The original type specimens of both taxa have not been located, so new type material has been chosen.
  Classification of species within the genus is very difficult, as several trunks have been described as species, and a further fourteen species are known from detached leaf remains, but there is no way of telling which leaf remains go with which trunk remains (if any).
