Only by bringing together plants
from around the globe and a variety of modern
environments can a dinosaur-age scene be recreated.
Some of the plants, like ginkgos, look virtually
the same as their extinct ancestors; some, like
the conifer Araucaria, were the dominant
trees of the forests 110 million years ago. Plant
groups alive at the time of the dinosaurs, include
mosses, horsetails, ferns, tree ferns, cycads,
ginkgos, conifers, palms, blooming water lilies
and magnolias.

Early land plants inhabited a hot, humid environment.
300 million years ago, many land areas were covered
in wet forests of giant clubmoss, horsetails and
ferns. These seedless plants reproduce with spores,
which require humid environments to survive.
Horsetails (Equisetum) have a
central, hollow stem with whorls of leaves
or thin branches. They hold their spores
in a cigar-shaped “cone” at
the top of the plant. Horsetails date
back to ~370 million years ago. During
the beginning of the dinosaur era they
grew to be nearly 30 feet tall (10m.)

Ferns live in a wide range of environments.
They have large leaves (fronds), which
are made up of several smaller segments
(pinnae). Ferns produce spores on the
undersides of their fronds. Ferns date
back ~370 million years ago.
