206 MEMOIRS OF THE CARNEGIE MUSEUM 
In the quarry designated as No. 3 in the accompanying illustration, there were 
found from five to nine individuals of Daphanodon superbus, of which No. 1589 is 
practically a complete skeleton. The latter was found imbedded together with 
another individual of the same species not fully adult. The soft sandstone in which 
the two were found was taken out in a large block and transported to the Museum. 
On examination it was found that the adult individual was partly articulated, 
especially the vertebral column and portions of the feet. The tail was found 
attached to the sacrum and thrown backward in a graceful curve so that the tip 
was lying close to the pelvis and abdominal region. The anterior nine vertebree and 
the anterior portion of the tenth were preserved in position. At this point the 
caudal region had been exposed and the vertebree had dropped out. By carefully 
measuring the natural curve, in which the tail was undoubtedly placed, its length 
was ascertained and the missing yertebree were either restored in plaster, or by other 
vertebree which were found in the talus below the place where the skeletons were 
dug out. The ribs of No. 1589 are not well preserved while those of the younger 
individual, No. 1589a, are quite complete. The posterior portion of the sternum is 
not present. One hind limb and foot of No. 1589 was found articulated. 
The posterior portion of the pelvis is weathered away, as is also the extreme 
anterior portion, leaving only the middle region. When material other than the 
type is used in the following description it is only for the purpose of elucidation and - 
the catalog number will be mentioned in connection with the specimens referred to 
in order to prevent confusion. 
Scattered remains of a number of individuals, apparently of the same species, 
were found in all of the Agate Spring Fossil Quarries, but in Quarry No. 3 were 
found the most abundant remains of Daphenodon swperbus. Besides the type of 
Nothocyon annectens Peterson and another small carnivore described later in this 
paper there was little else found in Quarry No. 3 except remains of Daphenodon 
superbus. Thisis interesting from the fact that hardly more than a stone’s throw to 
the north and practically on the same level, the very rich and classic quarries, No. 
1, No. 2, and the “University Quarry” are located (see Fig. 1). The lithological 
characters of the bone layer of Quarry No. 3 are similar to those in the large quar- 
ries and it was observed that the same barren pinkish bedrock found in the main 
quarries is also present in this quarry. ‘The irregularity of the fossil-bearing stratum 
was observed to be quite like that in the quarries immediately to the north. As 
has been stated elsewhere, the stratum containing fossil bones in the Agate Spring 
Fossil quarries was most probably laid down by a stream full of shallow channels 
which shifted from time to time during its existence.
