M. Tzanou et A. Economouamilli, MARINE PENNATE DIATOMS FROM THE LOWER PLIOCENE DEPOSITS OF AGIOS THOMAS, AEGINA (GREECE), Nova Hedwigia, 60(3-4), 1995, pp. 423-455
Material from the lower Pliocene deposits of Agios Thomas (also known
as ''Ag. Demitrios'' according to Ehrenberg) on the island of Aegina w
as studied. A total of 97 taxa of pennate, predominantly marine, diato
ms were identified; an addition of 55 taxa were not decisively recogni
zable due to poor frustule preservation. The morphological variability
of the identified diatoms is presented through short taxonomic descri
ptions coupled with photographic documentation by L.M. Valve dimension
s were mostly lying at the lower variability limits given for the type
specimens, and only small variation in valve structure was observed.
The majority of the taxa found (87 out of 97) are reported for the fir
st time as fossils from the Aegina Island and thirty one (31) taxa rep
resent new records for Greece.
