  abstract = {{T}he present paper deals with the charophytes collected by {H}. {F}aure and {P}. {M}. {V}incent from outcrops of lacustrine deposits inside the caldera "{T}rou au {N}atron" at an altitude of 1875 m above sea level. {C}haraceae represent up to 93% of these carbonates and characterise a new type of sediment, defined as "{C}haraceite". {T}he remains consist in vegetative (thallus) fragments and in gyrogonites (the calcified fructifications of the {C}haraceae). {T}he presence of both these types of materials and their high frequency indicate in situ fossilisation of the former fresh water vegetation, termed a "charophyte meadow". {T}he topographical position of the deposits corresponds to a rocky plateau or bench on the slopes of the caldera, located c. 300 m above the present-day floor of the caldera. {T}he development and preservation of the charophytes lead to conclude that the lake was at least 300 m deep at the time when the plants grew. {R}adiocarbon dating of the thallus fragments provided an age of 14,260 +/- 300 yr {B}.{P}. {T}his age is consistent with analyses obtained previously on gastropod shells from {T}rou au {N}atron and indicates high lake level in the {T}ibesti {M}ountains during the {L}ate {P}leistocene.},
