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…

Flore du Jurassique basal de la ville de Mende (Lozère) : synthèse des gisements historiques, nouvelles données sédimentologiques, paléontologiques e…

2019

Resume Au cours du XXe siecle, la majorite des sites a plantes fossiles (Hettangien–Sinemurien) de la ville de Mende ont disparu a cause d’une importante urbanisation ou bien sont tombes dans l’oubli. Cet article presente une synthese des gisements a vegetaux fossiles, depuis leur decouverte au XIXe siecle jusqu’aux campagnes de prospection recentes. De nouvelles donnees lithostratigraphiques et paleobotaniques sont apportees pour deux sites historiques (le Ravin del Pouset et le Petit Seminaire), ainsi que deux localites fossiliferes dernierement decouvertes (route du Causse-d’Auge et route de Gardes). Cette etude revele la diversite des lithofacies contenant les plantes (dolomudstone, mar…
