 mont County, Colorado. 



Horizon. — Morrison, Upper Jurassic. 



1 A letter to the writer from Mr. Charles E. Felch, a brother of the late M. P. Feleh, who collected the Ceratosaurus skeleton 

 and other fossil remains, gives some interesting first-hand knowledge of the discovery of fossils at Canon City, Colorado. With 

 his kind permission I quote the following from his letter of February, 1915: 



"I visited Colorado in 1876-77, spending most of the time at my brother's ranch. During this time we discovered, quite 

 near the ranch, and at the foot of one of the high cliffs of sandstone so common in this vicinity, what we supposed at the time 

 to be a section of a petrified tree, but on exhuming it from the disintegrated sandstone, we found that instead of being vegetable 

 origin, it was a portion of a thigh bone of some gigantic prehistoric animal. Quite unaware of its scientific value, and viewing it 

 only as a curiosity, we took it to the office of the local newspaper in Canyon City, where it attracted the attention of a visiting 

 scientist, Prof. Mudge, State geologist of Kansas, and through his instrumentality it was sent to Prof. Marsh, of Yale, who, being 

 greatly impressed by the importance of the discovery, visited the locality in person, and at once put Prof. Mudge in charge of 

 excavation work, which he pursued until his death about a year later, after which my brother, who had been working with Prof. 

 Mudge, was given charge of the work, and continued at it for eight years, shipping the fossils as quarried to New Haven. It was 

 only very recently that I learned that the bones had been removed to Washington."
