Fossil plants collected from Triassic-Jurassic rocks, Carapace Nunatak, Allan Hills area, southern Victoria Land

Fossils from Carapace include fossil conifers, some anatomically preserved. A new, floristically rich Late Triassic site was discovered in the Allan Hills.

The flora here includes ferns and equisetophytes, but is dominated by seed plants, including true cycads, conifers, ginkgophytes, dominant corystosperms (Dicroidium leaves, Umkomasia seed-bearing structures and Pteruchus pollen organs), and the first example of the peltasperm foliage Lepidopteris from continental Antarctica.
