Cycadeoidea
Cycadeoidea is an extinct genus of bennettitalean plant that is known from fossil finds in North America and Europe and lived during the Jurassic and Cretaceous periods.
Taxonomy
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).
Description
Cycadeoidea stems were "short and barrel-shaped," with a "crown of pinnate leaves" atop the stem. The majority of Cycadeoidea species were bisexual. The genus may have undergone self-pollination, although it is also possible that insects were involved in the process. The size and shape of the trunk has been used to distinguish species, however forms intermediate between two species suggest the two might be merely different-sized or aged plants can't be excluded.

Drop The Bomb
by: Scotty D.Sorry, could you make the music louder?
Yeah drop the bomb! Just drop the bomb!
Getting sick and tired of the fossil-like system,
now or never it's the time to resist 'em,
it's easy to blast them all away,
pull a trigger push a button say ADIOS today,
don't get me wrong I'm a pacifist,
the mind can do more than the fist.
Explosives are not what it takes
(you know, terrorists always make these mistakes,)
what we gotta do is build momentum,
if you need the right tools invent 'em,
ride the wave of time come feel the rhythm,
the march to the future has begun get with'em,
the brain is the generator of almighty power
either do it now or your master plan goes sour.
Yeah! are you ready to take that fall?
It's up to you to make that call to drop the bomb!
Yeah drop the bomb! Just drop the bomb! Let me see that bomb!
Just...
Learn from the sunken mu Atlantis
and from the head of the beheaded male-praying mantis,
we've all gotta make room for whats to come,
what we gotta do is build momentum,
if you need th right tool invent' em,
ride the wave of time come feel the rhythm,
the march to the future has begun get with'em,
the brain is the generator of almighty power
either do it now or your master plan goes sour.
Yeah! Are you ready to take that fall?
It's up to you to make that call...
(And if it don't work then make the real thing wipe it out)
So drop the bomb!
Yeah drop the bomb! Just drop the bomb! Let me see that bomb!
That bomb!
That bomb!
