This plant is nicknamed "Jurassic fern" by Ed Regis. However the plants were found abundantly in fossils more than 200 million years old, which is the Triassic period. Today it's common only in the wetlands of Brazil and Columbia. This is shocking Ellie Sattler, she knows that the spores of this plant contain a toxic substance (beta-carboline alkaloid) that makes its fronds irritating to the skin and potentially deadly when eaten. The toxin was 50 times more poisonous than Oleander.
