Paleo Pics from the myFOSSIL app 5 years, 4 months ago 5 years, 4 months ago5 years, 4 months agoAnother large specimen from my collection. Stigmaria is part of a plant root structure and is preserved as a cast containing no original material. These are commonly found in Carboniferous aged rocks (~358-298 million years ago). @mackenzie-smith do you know any other fun facts? #fossil
Sometimes we find permineralized Stigmaria and get original material. They come from trees called lycopods, also known as cub mosses. Today club moss only grow the max of about 2 ft. tall but extinct ones could grow more than 50 ft. tall. Like ferns they reproduce with spores but do so with a cone-like structure called a strobilus.
