i68 THE ALPS AND NORTHERN CARPATHIANS
Phylloceras and Lytoceras) of Perisphinctids which he identified with
three peculiar forms (Subplanites}) figured by Schlosser from the Kelheim
Diceraskalk of Bavaria. These have been found with certainty nowhere
else but in the Kelheim reef-limestone, which according to Roll and others
is an intercalation in and below the Solnhofen Beds (Lithographicum
Zone). Therefore if Spath's determinations are correct, Ernstbrunn
Limestone in some exposures must be older than Klentnitz Marls in other
exposures. Considering the observed lateral replacement of the two facies
and the acute tectonic disturbance, this solution is not improbable. That
the succession in the klippes cannot be upside-down is proved by overlying
Cretaceous and Tertiary beds (Abel, 1899, p. 285).
MIDDLE AND LOWER KIMERIDGIAN
The fauna of the Acanthicus Beds is widespread, usually in rather thin
red or varicoloured nodular limestones as in most parts of the Alpine-
Mediterranean region, but it is less favourably developed for collecting
than in Transylvania and Italy and has thrown no new light on the zonal
succession. In some parts of the Eastern Alps a coral reef facies is
developed, and in others there is passage into Aptychus beds and radiolarites
which are said to range in age from Oxfordian to Tithonian (Trauth,
1950, pp. 176, 185, 203, 207). Alleged transgression of the Kimeridgian
on to Lias and Trias, reported by early authors, probably has a tectonic
explanation. The red nodular facies is widely distributed in the inner
klippe chain of the Carpathians (Neumayr, 1873, p. 151; Passendorfer,
1928). An occurrence near Vienna has been lavishly illustrated (Toula,
1907, with 19 plates of ammonites, many new species) but the preservation
is so poor that few of the photographs can be interpreted.
OXFORDIAN
The Upper Oxfordian is also widespread and somewhat thin.
Ammonites of both Bimammatum and Transversarium Zones are recorded
from many places. Ringsteadia is reported from both the Eastern Alps
(Trauth, 1950, p. 176) and the Carpathians—R. vicaria Moesch sp.
(Neumayr, 1873, p. 152). In the Eastern Alps radiolarites are extensively
developed; they have many shallow-water intercalations and are unlikely
to have been formed at great depths (Trauth, 1950, pp. 185, 190).
An Oxfordian occurrence of outstanding interest is the limestone klippe
of Czetechowitz in the outer klippe chain of Moravia (Neumayr, 1870a;
Neumann, 1907). Here 4 m. of nodular limestone have yielded a remarkable
fauna comprising a mixture of the abundant Phylloceratids proper
to the Alpine-Mediterranean province with a host of Perisphinctids and
Cardioceratids which could occur anywhere in NW. Europe, and in
England in particular. The beds are known in the literature as Cordatus
Beds but, as Neumann (1907, p. 60) rightly pointed out, the fauna comprises
representatives of both late-Cordatum and Transversarium Zones.
In fact, probably all the Cardioceratids figured are of the English Plicatilis
