Charophyte research A study on the Paleocene charophyte flora from the South Gobi area in the Junggar Basin (China) and on the Paleogene fossil record of charophytes is published by Cao et al. (2022), who interpret their findings as evidence of the dispersal of charophyte lineages from Asia to Europe in the middle to late Eocene, possibly facilitated by waterbirds.
