Early-Middle Triassic (Anisian) Fossil Flora from Mallorca (Spain)
Published by Dolomythos Museum, Innichen, South Tyrol, Italy
An interesting new fossil flora from the Balearic Islands in Spain will
be described. Although the Estellencs site has only been known since
the 19th century, new research has added a rich conifer association.
Estellencsia saezii nov. gen. n. sp. with its elongated female cones and
winged seeds has the same parental affinities with today’s Picea or Keteleeria
species. The community was rich in Araucarian-ancestor species.
Aethophyllum stipulare var. balearica was a low-growing, smallsized
and monoecious conifer, generating fully developed cones on just
15- to 20-cm high plants. Parented plants were previously known just
from the French–German coeval layers, as well as Pelourdea vogesiaca
with its tongue-shaped leaves. Ortiseia collii n. sp. was characterized
by its scales with only one embedded seed, like the extant Araucaria.
The fern Anomopteris mougeotii and the horsetail Equisetites mougeotii
– widespread plants in European Anisian layers – were common,
whereas Sagenopteris nadalii n. sp., usually a seed fern common in
the Jurassic, constitutes a surprisingly frequent flora element. A rich
accompanying inchnofauna and insect biocoenosis put it beyond doubt
that this site is important.
