STRATIGRAPHY OF THE DEYONIC FISH BEDS AT MIGOUASHA, PROVINCE 



OF QUEBEC 



The fish-bearing beds of this region are probably the most re- 

 markable of any Devonic deposits known in respect to the abundance 

 and excellent preservation of their fish remains. These have entered 

 into the literature of paleontology extensively and generally under 

 the name of the fishes or beds of Scaumenac bay, Escuminac, Fleu- 

 rant point or Yacta point. In view of the polynomial character 

 of the region it is well to be explicit. These beds lie on the north 

 shore of the Restigouche river where it broadens into the head- 

 waters of the Bay of Chaleur. Their location is straight across 

 the water from Dalhousie, N. B., whence a ferry runs to what is 

 known as Migouasha landing, where the rock wall of the bay is 

 degraded to the water. At a quarter of a mile east of Migouasha 

 landing the red rocks of the " Bonaventure " formation come 

 down to the water in an eastward dip, and at about three-quar- 

 ters of a mile westward of the landing is the projection of Fleu- 

 rant point. The high-colored " Bonaventure " beds rising from 

 the water line at the east, present a contact with the underlying 

 gray fish-bearing beds for a distance but on passing Migouasha 

 they retreat into the hills of the background and all the rock beds 

 exposed thence westward to Fleurant point are the gray sands 

 and shales with fish. In the voluminous literature relating to the 

 contents of these rocks little has been recorded as to their strati- 

 graphy and the essential evidence which has led to their general 

 acceptance as Upper Devonic has been brought out by Doctor 

 Ells's account of the locality given thirty years ago. These gray 

 Devonic sands with their nodules of various sizes, carrying 

 Bothriolepis, Scaumenacia and several other fishes in extraordi- 

 nary preservation and the blocky masses filled here and there 

 with their remains, attain a considerable thickness at the highest 

 point along the stretch of coast, perhaps a clean exposure of 100 

 feet and, in view of their dip eastward, a total thickness of not far
