Project Exploration’s Mesozoic Garden
includes representatives from all plant groups alive
at the time of the dinosaurs, including mosses, horsetails,
ferns, tree ferns, cycads, ginkgos, conifers, palms,
blooming water lilies and magnolias. 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.
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.
