These fresh water aquatic plants were some of the first to develop on Earth, with fossilized examples extending back as far as the Silurian Period or 443 to 419 million years ago. Many species of these Charophytes are now extinct but modern examples are common in riparian areas, estuaries, and wetlands. Charophytes include green algae and stoneworts.
