first authentic avian relics, those of Archwopteryx, already a 

 long way along the road to avian perfection, coming as it does 

 from the Middle Jurassic, would surely imply birds in some 

 stage of their evolution during Newark time. 



Professor C. R. Eastman, in a characteristically excellent 

 paper (1911, p. 28), gives the following summary :

 Triassic Rocks of Eastern North America. [In this list the 

 names of those species occurring in the Connecticut valley are 

 denoted by an asterisk.]

This fauna, except for one crossopterygian, is made up exclu- 

 sively of ganoids and, judging by comparisons made with fish 

 faunas of the Old World, is considered to be " of more or less 

 manifold nature, and corresponds in a general way to the inter- 

 val between the uppermost Muschelkalk and the basal division 

 of the Keuper in the Mediterranean region." 



The fish remains are nearly all from the two general levels 

 of black bituminous shale, which also contain the plant relics, 

 in varying profusion. Rarely are footprints found in juxta- 

 position to the fishes and never, so far as I am aware, upon the
