64 The Upper Cretaceous Deposits of Maryland 



Conrad, occurs in so poor a state of preservation that it has not been 

 described. Another very conspicuous element in the fauna is a Pa nope 

 which is, like Corbula, a muddy bottom form. Turritella is also abundant 

 and Peclen and Oardium fairly common, while Tenea and S'olyma have a 

 limited representation. 



The fauna, meager as it is, very clearly indicates muddy bottom con- 

 ditions, probably estuarine in character and quite possibly at the mouth 

 of the ancient Potomac. 



The flora of the Magothy formation has afforded numerous types of 

 plant life including ferns, cycads, conifers, and dicotyledons that present 

 many points of difference from the Earitan flora, and are of more modern 

 aspect. Among the more important fossiliferous localities that have 

 afforded plant remains may be mentioned "Cape Sable" (North Ferry 

 Point) on the Magothy River, and Grove Point at the mouth of the 

 Sassafras River. Among the characteristic species found in the Magothy 

 of Maryland are:
