Rediscovery of the allegedly “destroyed” holotype of Weltrichia fabrei Saporta, 1891 from the Rhaetian?/Hettangian of Lozère (Southern France)
2018
7 pages; International audience; A sandstone slab bearing plant macro-remains was rediscovered during recent investigations led in the buildings of the old Musée Ignon-Fabre (Mende) which were closed in 1995 and emptied in 2003. The study of the slab clearly allows it to be identified as the holotype of Weltrichia fabrei Saporta, 1891 which has been considered destroyed since the end of the 20th Century. Gaston de Saporta described this Bennettitalean fructification based on a cast and considered the type locality as Rhaetian in age. In the present paper, based on the holotype, W. fabrei was revised in order to describe and illustrate the specimen in detail. It consists of a cup with one wh…
Terrestrial plants and marine algae from the Late Jurassic lithographic limestone of the Causse Méjean (Lozère, southern France)
2016
International audience; A new Late Jurassic flora was discovered in the fossiliferous lithographic limestone of the Causse Méjean, Lozère (southern France). It consists of the first Kimmeridgian/Tithonian plants from this area. Fossil plants are represented by megaremains preserved as impressions. This flora shows a co-occurrence of terrestrial plants and marine algae. The land plants include vegetative remains ascribed to bennettitaleans (Zamites Brongniart, 1828), conifers (Brachyphyllum Brongniart, 1828), and pteridosperms (Cycadopteris Zigno, 1853). Marine algae were ascribed to dasyclads (Goniolina D’Orbigny, 1850). Lithological and palaeontological features suggest preservation in a f…
