REPORT OF THE DIRECTOR, I922 9 
The Temple Hill Mastodon. The splendid skeleton has now been 
set up in the Museum. Some account of its discovery near Temple 
Hill, 4 miles west of Newburgh, was given in the last report of the 
Director. The skeleton has proved to be that of a large male nearly 
as large as the Warren mastodon, which still bears the palm for size 
and completeness; though in fact in certain measurements the 
Temple Hill skeleton as mounted carries some larger dimensions. 
There are features of special interest in this skeleton: (1) The 
presence of one of the styloid processes of the temporal bone, 
extending into the throat and connecting with the hyoid arch, which 
has been observed but once before; (2) the presence of the milk 
teeth which have been retained after the full development of the 
adult molars, thus giving the animal a set of twelve molars instead 
of the normal adult number of eight; (3) the circling tusks which 
overlap in front on beveled planes of wear and show the extreme 
overspecialization of these parts. The Museum acknowledges again 
the help of the late Emerson McMillin in meeting the cost of 
acquiring this skeleton, which is to be known as the McMillin or 
Temple Hill mastodon. The skeleton has been skilfully mounted by 
-Ward’s Natural Science Establishment of Rochester, N. Y. 
The Postglacial mammals of New York. There is in press a 
special bulletin on the mammalian remains which have been found 
in the surface deposits of Postglacial age and this include all occur- 
rences of the mastodon and mammoth and their distribution. This 
important record, compiled from all available sources in literature 
and museums, gives an interesting panorama of the higher fauna 
which occupied the State in comparatively recent times but most of 
whose members are now extinct.* 
Other paleontological work. The monograph of the strati- 
graphy and paleontology of the Upper Ordovician rocks of New 
York, comprising the Utica, Frankfort and Loraine formations, on 
which Doctor Ruedemann, Assistant State Paleontologist, has been 
engaged for several years, has been finished and the first part, the 
Stratigraphy of the Upper Ordovician rocks of New York, is ready 
for printing as a bulletin. The more important second part, dealing 
with the fossils of these rocks, requires considerable illustration and 
is held until the pressure of printing other accumulated reports is 
somewhat relieved. The principal results of this work have been 
mentioned in former reports. 
* This record has now been issued as a bulletin of the Museum under date 
of 1922 and entitled “The Mastodons, Mammoths and Other Pleistocene 
Mammals of New York State” by C. A. Hartnagel and Sherman C. Bishop.
