Keuper, but Eastman/^ having treated the whole fish fauna, and also 

 being familiar with the European fish faunas, considers them as more 

 ancient. He says that several species of SeTninotus ( — Ischypterus) 

 are nearly related to those from Perledo and Besano in the Italian 

 Alps, and therefore correlates the fish fauna with the upper Muchel- 

 kalk or Lettenkohle. 



From all of this it must be concluded that the numerous but not 

 yet sufficiently known Parasuchians and Labyrinthodonts from 

 North Carolina, Virginia, Pennsyl- 

 vania, New Jersey, Connecticut, and 

 Massachusetts do not belong to the 

 youngest, but to the middle Trias,

Avhich would be about the time between upper Muschelkalli: and 

 lower Keuper, but that the Saurischians in Connecticut and Mas- 

 sachusetts belong to the upper Keuper or the Ehaetic. This also 

 seems to be the view of Lull, who, in 1915, assembled the American 

 evidence on this question, but without comparing extensively with 



European evidence.
