Palm trees were missing on the volcanic islands of the Triassic atolls, as they were not to turn up until over 100 million years later! Yet there were palmlike trees that were related to primitive plants today represented by the ginkgo or sago cycad. Pterophyllum belongs to the now-extinct Benettitales, which populated the coasts in the Triassic period along with primitive conifers and ferns. Palm trees would not have been a feature of these beaches!

Daonella are typical bivalve molluscs from the Middle Triassic period (247-237 million years). Their thin, flat shells were reinforced with radiating ribs that, beside their circular to sub-triangular shell outline, characterize the species. D. lommeli is one of the largest and most widespread species. As it is often found in rocks deposited in the open sea, it is presumed that it lived afloat the water thanks to its thin, wide shell.
