The generic name Discinispora Wang,
Zhang, Bek et Pfefferkorn was originally
created for spores with an operculum-like
structure that were found in a
permineralized Noeggerathialean cone.
Subsequently it was observed that up to
three round and smooth openings can
occur in different positions on the surface
of a single spore. In light of the new
observations, the previous interpretation
as an operculum cannot be sustained. An
interpretation implicating insect punchand-sucking
activity was suggested for
these round structures. This new interpretation
makes it necessary to withdraw
the original diagnosis and the taxon. The
insect-inflicted damage now is assigned
to the ichnotaxon Circulipuncturites
discinisporis Labandeira, Wang, Zhang,
Bek et Pfefferkorn under the rules of the
ICZN, rather than those of the ICBN
that typified the insect-damaged hostplant
spore.

Cenomanian - Maastrichtian ostracods
from Gabal Arif El-Naga anticline,

135 surface samples are collected from the
Cenomanian-Maastrichtian succession of Gebel
Arif El-Naga anticline, eastern Sinai
(Egypt) and examined for their ostracodal
content. 76 ostracod species and subspecies
were recognized and discussed. The lithological
characteristics of this succession were also
subdivided into five formations, from base to
top as follow : Halal Formation (Cenomanian),
Abu Qada, Wata Formations (Turonian),
Themed Formation (Coniacian-Santonian) and
Sudr Formation (Campanian-Maastrichtian).
Most of the recorded species in these rock
units were correlated with their counterparts in
the Levant, Middle East and North Africa and
some with West Africa, Europe and South
America suggesting biogeographic relationships
between these regions across the Cretaceous
Trans-Saharan Seaway. The stratigraphic
range of these ostracods pointed out to
the occurrence of 10 local ostracod assemblage
zones in the present study. These zones
were correlated with the planktonic foraminiferal
zones of the same area and ranges from
base to top as follow : Metacytheropteron-
Cytherella-Neocythere Assemblage zone
(early Cenomanian), Dolocytheridea atlasica–
Neocyprides vandenboldi Assemblage zone
(late Cenomanian), Xestoleberis derorimensis-
Oertliella dextrospinata Assemblage zone
(early Turonian), Cythereis-Asciocythere-
Ovocytheridea Assemblage zone (late Turonian),
Cythereis oertlii-Phyrocythere lata
Assemblage zone (Coniacian), Cythereis cretaria
cretaria-Limburgina miarensis Assemblage
zone (Santonian), Leguminocythereis
dorsocostatus-Protobuntonia campania Assemblage
zone (early Campanian), Brachycythere
beershevaensis-Spinoleberis megiddoensis
Assemblage zone (late Campanian),
Rushdisaidina supracretacea Zone Assemblage
zone (early Maastrichtian) and Cristaeleberis
fornicata Assemblage zone (late Maastrichtian).
