In view of the paucity of organic remains in the red sand-

age or identity of the formations in which they are found. The 
rocks containing these fossils, also exhibit peculiarities of stratifi- 
cation, dislocation and lithological appearance, as well as a simi- 
larity in other small but undetermined fossils, which tend to es- 
tablish the cotemporaneous character of these formations.
