Jha. Vankonijnenburgvancittert et Ca. Meyer, PLANT REMAINS FROM THE VELLERAT FORMATION (OXFORDIAN) OF THE SWISS JURA MOUNTAINS, Eclogae Geologicae Helvetiae, 89(3), 1996, pp. 1117-1136
The Natica Member of the Vellerat Formation (Late Oxfordian) has yield
ed a small florula in the quarry La Charuque (Pery-Reuchenette) in the
Swiss Jura mountains. Four taxa have been found: the bennettitalean l
eaf Zamites cf. feneonis, the araucariaceous conifer Brachyphyllum ci.
thuioides and the cone-scale Araucarites cf. moreauana and the cheiro
lepidiacean conifer Pagiophyllum araucarinum as well as male cones of
the genus Masculostrobus that are thought to belong to the latter spec
ies. The size of the plant remains and the association with seeds and
cones points to a parauthochtonous assemblage. The palynological analy
sis indicates a small plant community growing near the coast.
