The fern group of plants have fossil
records extending back to the Middle Devonian periods (350 - 400
million years ago). Ferns have leaves, called fronds, which
usually consist of leaflets. They live in a wide range of
habitats, ranging from the tropics to cold temperate regions. Pteridospermsare
plants similar in appearance to the fern and are popularly called
seed ferns.

Seed Fern - Alethopteris
250-300 Million Years
|
This plant was characterized by large
fronds with toothed leaflets. Alethopteris
grew in elevated areas of hot swamps. The name is also used for a
number of similar frond shaped species which may, or may not, be
related. This is an excellent example of plant life during the
Late Carbiniforous to the Permian Period. Measures approx. 5 1/4" x
1 15/16" at its widest point.

Pecopteris Fern Fossil
250 - 300 Million Years
|
This is an excellent example of plant
life during the Late Carbiniforous to the Permian Period. Most of
these broke up before fossilization and only toothed fragments,
such as the one above, survived. This very large fossil measures
approximately 7 3/8 in. x 2 3/8 in.
