M. Talbot — Podokesaurus holyokensis. 479 



far for water in a semi-arid climate. In support of this inter- 

 pretation, also, may be added Barrell's suggestion that the rock 

 in which the fossil is embedded indicates deposition on a flood- 

 plain in a semi-arid region. It is significant that many of these 

 Connecticut valley sandstones that have dinosaur footprints 

 have also raindrop impressions. 



Through the courtesy of Professor Schuchert the specimen 

 has been sent to the Peabody Museum of Yale University 

 for development, where further study will be given it by Pro- 

 fessor Lull, to whom my thanks are due for many suggestions 

 in regard to the interpretation of this fossil. 



Mount Holyoke College, April, 1911.
