A 350-million-year-old fossil of a fern-like plant that lived before dinosaurs and mammals stalked the Earth has been identified as a new species, 50 years after its discovery. He gave it to the state's geological survey, which left the fossil languishing in a drawer for decades before it was re-discovered by French geologists. 'We named the genus Keraphyton (like the horn plant in Greek), and the species mawsoniae, in honour of our partner Professor Ruth Mawson, a distinguished Australian palaeontologist who died in 2019.' The xy cells are xylem tracheids, serving in the transport of water, while oc and ic points to the outer cells, which are near the cells at the surface. This laboratory is particularly interested in fossils from the Devonian-Carboniferous geological period, to build a more detailed understanding of plant evolution during this era.
