Plateosaurus and other Triassic vertebrates in Germany: new papers
From: Ben Creisler
Two papers in the new issue of open-access Palaeodiversity (free pdfs):
RAINER R. SCHOCH (2011)
Tracing SEEMANN’s dinosaur excavation in the Upper Triassic of Trossingen: his
ﬁeld notes and the present status of the material.
Palaeodiversity 4: 245–282
The ﬁeld notes of REINHOLD SEEMANN, who conducted the 1932 dinosaur excavation
at Trossingen, are published for the ﬁrst time. An English translation of the
whole text is also provided. Quarry maps and stratigraphic sections were
redrawn and compared with new data gathered in ongoing excavations. Of the 65
ﬁnds listed by SEEMANN, only 21 have survived the Second World War
(Plateosaurus: 18, Proganochelys: 3). This includes most of the well-preserved
skeletons, which had been moved to safe places during the war. An overview of
these ﬁnds and their present state is given for the ﬁrst time. This reveals
major differences in preservation of bones, and it adds to the knowledge of
bone completeness classes at Trossingen. The missing ﬁnds were probably
destroyed by ﬁre in 1944, and there are no remains from these specimens left.
In combination with the ﬁeld notes and sketches, the new data on SEEMANN’s
material may serve as a platform for
future studies of and excavations at the Trossingen lagerstaette.
HANS HAGDORN & RAOUL J. MUTTER (2011)
The vertebrate fauna of the Lower Keuper Albertibank (Erfurt Formation, Middle
Triassic) in the vicinity of Schwäbisch Hall (Baden-Württemberg, Germany).
Palaeodiversity 4: 223–243
In the vicinity of Schwäbisch Hall, the Lower Keuper (Ladinian) Albertibank is
characterized by a small-scale lateral facies change and a distinctive fauna
composed of ostracods, ﬁshes, and lower tetrapods, comprising the remarkably
abundant polzbergiid actinopterygian Serrolepis suevicus, small unidentiﬁed
species of ?Redﬁeldiiformes and Saurichthyidae, the small brackish water shark
Lonchidion, two dipnoans, a large coelacanthiform, the temnospondyl amphibians
Mastodonsaurus and Gerrothorax, a small nothosaur, and the "rauisuchian"
Batrachotomus. Facies and fauna give evidence of an occasionally dry falling
lacustrine environment. The dentition of Serrolepis is indicative of a
specialized durophagous diet, presumably on ostracods.
