246 THE IBERIAN PENINSULA
Blumenthal and Fallot in numerous works and most ably revised and
synthesized by Fallot (1931-4). Fallot gives such a wealth of information,
with long lists of ammonites, that it is impossible here to attempt more
than a bare outline of his results, laying stress mainly on the ammonite
succession and its significance for wider correlations, and omitting any
attempt to reproduce his brilliant analysis of the distribution of faunas
and facies within the area, with his important tectonic arguments. No
one wishing to follow up those lines of enquiry can dispense with his
treatise.
[NEOCOMIAN
In the west and centre there is an unbroken passage up from Tithonian
into similar Berriasian and Valanginian limestones or marls with
Neocomites, Olcostephanus, etc. (Fallot, 1934, pp. 76, 86, 105, 107). In
the NE., 'Wealden Beds' up to 100 m. thick unconformably overlie
various parts of the Jurassic. The boundary of these beds is shown by
Brinkmann & Gallwitz (1933, p. 75, fig. 16), but neither their age nor
their relation to the marine Neocomian is established.]
TITHONIAN (up to 250 m.)
Bertrand & Kilian (1889, p. 439) recognized two subdivisions, linked
by numerous ammonites in common, but the lower division containing
some Jurassic forms and the upper some Cretaceous. Fallot (1934)
defined the two more precisely and recognized also a Middle Tithonian.
Upper Tithonian. Fallot (1934, pp. 90, 91, 100) gives three long lists
of forms from different localities, the following being the most important
species:—
Phylloceras serum (Oppel) Himalayites depressus (Uhlig)
Phylloceras calypso (d'Orb.) Micracanthoceras microcanthum (Oppel)
Phylloceras semisulcatum (d'Orb.) Spiticeras pseudogroteanum (Kilian)
Lytoceras cf. montanum Oppel Negreliceras negreli (Math.)
Lytoceras sutile Oppel Neocomites occitanicus (Pict.)
Lytoceras liebigi Oppel Neocomites cabrensis Kil.
Lytoceras honnoratianum (d'Orb.) Simoceras volanense (Oppel)
Haploceras elimatum (Oppel) Aspidoceras avellanum (Oppel)
Haploceras caractheis (Oppel) Aspidoceras cf. raphaeli (Oppel)
Berriasella abscissa (Oppel) Aspidoceras cf. liparum (Oppel)
Berriasella carpathica (Oppel) Aspidoceras iphicerum (Oppel)
Berriasella calisto (d'Orb.) Perisphinctes sublorioli Kilian
Berriasella privasensis^ (Pict.)
Berriasella chaperi (Pict.)
Berriasella lorioli (Oppel)
In the Penibetic region the Upper Tithonian with Calpionella alpina,
developed in some places in the form of red crinoidal limestone with
Spiticeras celsum (Oppel), overlaps on to the Palaeozoic (Fallot, 1934,
pp. 78, 79).
