Abstract
THE coastal plain of Maryland, a region forming part of the Atlantic slope which extends from the crest of the Alleghanies to the sea, consists of Mesozoic and Tertiary strata deposited in orderly sequence since the dawn of the Cretaceous epoch. It is with the estuarine and fluviatile beds of the Lower Cretaceous, or Potomac, group that this important volume is primarily concerned. With the exception of a few Reptilia and Mollusca, described respectively by Mr. R. S. Lull and Mr. W. Bullock Clark, the life of the period is represented by a rich flora, which has been entrusted to Mr. E. W. Berry. As stated in the preface, “The necessity of some sort of systematic treatment of the maze of described forms in the literature of the Potomac which would enable the geologist or botanist to obtain some idea of the flora has long been felt.” This want is satisfactorily met by the publication of the reports included in the fourth volume of a series dealing with the stratigraphy and palaeontology of Maryland.
