(2025).
* Evidence of a staggered recovery of plant communities from the Sydney Basin (Australia) in the aftermath of the Permian–Triassic extinction event, indicative of the presence of a succession gymnosperm-dominated and lycophyte-dominated plant communities lasting until the early Middle Triassic, is presented by Amores et al. (2025).
