Review of Palaeobotany and PalynologyElsevier Publishing Company, Amsterdam - Printed in The NetherlandsTHE STRATIGRAPHICAL DISTRIBUTION OF FOSSIL DINOFLAGELLATESWILLIAM ANTONY S. SARJEANTDepartment of Geology, The University, Nottingham (Great Britain) (Received August 28, 1966)summaryThe stratigraphical distribution of fossil dinoflagellate cysts is reviewed and the known ranges of species hitherto described are illustrated in tabular form. The problems of earliest appearance and relationships are considered. On the basis of morphological groupings in relation to known stratigraphic distribution, the classification of the cysts above generic level is discussed.historical introduction!It is now 130 years since fossil remains of dinoflagellates were first discovered by Christian Gottfried Ehrenberg, during examinations of sections of Upper Cretaceous flint from Delitzsch, Saxony. Ehrenberg described his discovery during 1836 to various colleagues, among them Baron Alexander von Humboldt, but presentation of the paper in which they were described did not take place until luly 20th, 1837, and the paper was not pubhshed till 1838. In the interim, von Humboldt had forwarded some of Ehrenberg's slides to the French Academy of Sciences: one of its members, C. R. Turpin, described them to the Academy on January 2nd, 1837, his interpretation differing widely from Ehrenberg's. The quicker publication of the Academy's Comptes Rendus lost Ehrenberg the honour of first publication, nor were his findings followed up on the continent of Europe for almost a century.Ehrenberg visited England in 1838, speaking at the Newcastle meeting of the British Association, attending a September meeting of the Geological Society of London, and finally, embarking on a collecting trip on the south coast, unhappily terminated by injury following a fall from a mail-coach at Brighton.
