Palaeozoic Protosphagnales constitute the largest group of extinct mosses of a still uncertain affinity. Their leaf areolation resembles that of modern Sphagna, which is strikingly different from any other mosses...
Tiny 135-million-year-old moss fossils found in rocks from western Canada preserve exquisite anatomical details. These fossils open an unexpected window on moss evolution, as they allow for recognition of living moss...
The presence in the specimens of both epicormic shoots and traumatic growth zones, combined with the observation of some disorientation of the wood structure in some parts of the trunks, suggest that these trees were...
Plants of the Early Devonian epoch (419-323 million years ago) are crucial to reconstructing the initial radiation of tracheophytes, yet few are understood as whole organisms. Unearthing the habits of Sengelia radicans...
This study of the fossilised stem of a royal fern in Lahar deposits from Korsaröd in Scania includes cellular details that are ‘exquisitely preserved’.
