That these lower Ccnomanian beds contained fossil plants has been 



known for upwards of a century. Cottii ' having described the beds as 



early as 1836. Six species were recorded from this locality by Sternberg 



in his " Flora der Yorwelt," and it is mentioned by Brongniart. Zenker, 



linger, 2 Gceppert, Bronn, Geinitz 3 and others. Geinitz and Gutbier ' 



enumerated nine species of plants in 1S43. It remained for Ettings- 



hausen ' to do justice to this flora in his little monograph published in 



1867 in which forty-two species arc enumerated. In 1885 Englehardt ' 



discussed the forms of Credneria from Niederschcena and in 1891 he made 



a considerable addition to the flora. 7 Combining the identifications of the 



above-mentioned authors furnishes the following list of species:
