Tertiary A great many species of invertebrates are also found in these beds. The University 

 of Wyoming has not collected to speak of in the Tertiary fields, since our whole attention has 

 been given to the Jurassic. Incidentally, we have gathered some of the rare fossils; chief 

 among them being a few very fine specimens of the Green River fishes. The only fossil that 

 has been reported from the Pleistocene is an elephant, the lower jaw of which is at the 

 University of Wyoming. 



" It is not difficult to understand why Wyoming was justly celebrated as a great treasure 

 field for the museums of the world. Unlike so many other fields, no scientific man nor 

 expedition need turn their back on the State until they feel that they have been fully paid for 

 their efforts. To a certain extent collecting is a profession, and only men with keen eyes, who 

 have acquired the valuable trait of perseverance, accomplished much in any field. Wyoming, 

 however, presents greater facilities than any other locality, for, as Dr. Cope once said, 'if you 

 can't find diamonds, you surely can find stones, and in these bones.' Another feature that 

 presents exceptional opportunities to geologists or paleontologists is that while collecting 

 he is coming in contact with unexplored regions, rich in scientific data, rich alike for any 

 branch of geology. While fossils are being collected there is a great wealth in rock and 

 mineral species, and in the peculiar formations accompanying sedimentation. Collectors 

 entering the field should be provided with teams for transportation, camp equipage, and 

 all that is necessary to make life independent and comfortable."
