When was the fern fossil found?

This fossil was collected from the Hermit Shale by Frank Richardson in 1938, and is approximately 285 million years old. Although it looks very similar to a modern fern, we know that this plant was not a true fern, because it produced seeds instead of spores. In fact, these plants were the first to produce true seeds.

What are plant fossils called?

Plant fossils are classified into two groups: (1) macrofossils, which are the larger plant members, such as stems and leaves, usually detached and often fragmented; and (2) microfossils, which are the shells or resistant outer walls of minute plants, such as diatoms, or of pollen grains and spores. Fruits and seeds …

Are ferns endangered?

Several types of ferns are known as invasive species due to increased reproduction rate and ability to occupy new habitats quickly. Some species of ferns are listed as endangered because of the habitat loss (as a result of increased human activity).
