-±60 Veatch — Localities of Supposed Jurassic Fossils. 



The limestone is stratigraphically near the line of parting 

 between the Wasatch and Green River formations. Both 

 Meek* and Whitef have recognized the identity of these forms 

 with those found in beds of undoubted Eocene age at about 

 the same horizon, and have thus anticipated from paleontologic 

 data the conclusion reached by visiting the type locality. 

 Meek pointed out that the Cerithium is clearly a Goniobasis, 

 and suggested the name of Goniobasis nodtdifera, while 

 White regards it as but a variety of Goniobasis tenera (Cer- 

 ithium tenerum Hall). Turbo paludinwformis has likewise 

 been referred to the fresh water genus, Yivipara. 



Of Fremont's supposed Jurassic fossils, the plants are there- 

 fore upper Cretaceous and the invertebrates are Eocene.
