PALAEOZOIC FOSSILS IN THE DRIFT. F. IV. SardcsOU. 



So far as I have been able to learn, very few Palaeozoic fossils 

 have ever been found in the Drift formation of ]Minnesota, ex- 

 cepting in the scattered patches of Trenton shales and limestone 

 that are seen occasionally more or less mixed with the drift ma- 

 terial, but are merely torn up and left near their original position. 



But more than four years ago I picked up in Prospect park» 

 St. Paul, two fossils that are evidently not from the Trenton, a 

 honeycomb coral and a brachiopod. 



In 1889, two more were found by Professor Hall, in the Drift 

 at Dresser Junction, Wis., a honeycomb coral and a gastropod. 



Also Principal Childs sent for identification a number of fos- 

 sils from the drift at and near Morris, Minn., last August. 



Again, in the early part of the present winter some more 

 were found. I happened one day to be going through a railroad 

 cut near Kegan's lake (Minneapolis) and noticed some pebbles 

 like the fossiliferous ones from Morris, Minn. There was a 

 crinoid stem on one of them. Later brachiopods, and other forms 

 were found. All the Drift exposures from Parker station to 

 Cedar lake (four miles) were searched, and this same limestone 

 was found everywhere, and was often fossiliferous. The stone 

 itself is white and gray, very hard and compact, and occurs as 

 rounded pebbles, slabs and even boulders, very much scattered 

 throughout the Drift. 



For convenience in comparing the fossils I have made out 



These fossils seem to be Devonian.
