The author is particularly obliged to many Soviet specialists who not only
shared their knowledge and experience, but also provided the opportunity for him to
work on Lower Cretaceous sections in the southern regions of the USSR. In 1960
the author had the privilege of being member for six months of the Complex Southern
Geological Expedition of the Academy of Sciences of the USSR, which worked
in the Crimea, in the Caucasus and in the southern periphery of the Russian Platform.
Deep gratitude and respect is due to the late Prof. V. P. Rentgarten, to Prof.
N. P. Luppov and Prof. V. V. Drushchitz for providing information on the problems
of Lower Cretaceous stratigraphy in the USSR.
The author is grateful especially to Dr. N. Ruskova and Dr. I. Sapunov for reading
the manuscript of the book and for many good suggestions.
The completion of the present work would have been impossible without the
assistance of my colleagues from the Department of Palaeontology at Sofia University.
Mrs. N. Motekova and Mrs. M. Kehajova offered valuable assistance in
compiling the bibliography. Mrs. E. Dzonzurova has drawn most of the figures,
Mrs. C. DuSkova has typed parts of the manuscript. Mr. A. Vitanov facilitated the
settlement of a number of technical matters.
Many thanks to all institutions and persons not mentioned, whose various
contributions to the present work are highly appreciated. The shortcomings and
ommissions are entirely the author's own responsibity.
