piled up just as they came in from the West, never having been unpacked. 
Professor Cope’s assistant, Mr. Geismar, informed the writer that 
Hubbell’s collection was mostly fragmentary and not of any great value. 
Mr. Hubbell’s letters from the field unfortunately were not preserved, 
but it is likely that they did not make clear what a splendid find he had 
made, and as some of his earlier collections had been fragmentary 
and of no great interest, the rest were supposed to be of the same kind. 
When the Cope Collection was unpacked at the American Museum. 
this lot of boxes, not thought likely to be of much interest, was left until 
the last, and not taken in hand until 1902 or 1903. But when this 
specimen was laid out, it appeared that a treasure had come to light. 
Although collected by the crude methods of early days, it consisted of 
the greater part of the skeleton of a single individual, with the bones in 
wonderfully fine preservation, considering that they had been buried 
for say eight million years. ‘They were dense black, hard and uncrushed, 
even better preserved and somewhat more complete than the two fine 
skeletons of Allosaurus from Bone-Cabin Quarry, the greatest treasures 
that this famous quarry had supplied. ‘The great carnivorous dinosaurs 
are much rarer than the herbivorous kinds, and these three skeletons 
are the most complete that have ever been found. In ali the years of 
energetic exploration that the late Professor Marsh devoted to searching 
for dinosaurs in the Jurassic and Cretaceous formations of the West 
he did not obtain any skeletons of carnivorous kinds anywhere near as 
complete as these, and their anatomy was in many respects unknown or 
conjectural. By comparison of the three Allosaurus skeletons with 
one another and with other specimens of carnivorous dinosaurs of 
smaller size in this and other museums, particularly in the National 
Museum and the Kansas University Museum, we have been enabled 
to reconstruct the missing parts of the Cope specimen with very little 
possibility of serious error. 
An incomplete skeleton of Brontosaurus, found by Dr. Wortman 
and Professor Knight of the American Museum Expedition of 1897, 
had furnished interesting data as to the food and habits of Allosaurus, 
which were confirmed by several other fragmentary specimens obtained 
later in the Bone-Cabin Quarry. In this Brontosaurus skeleton several 
of the bones, especially the spines of the tail vertebrae, when found in 
this rock, looked as if they had been scored and bitten off, as though by 
some carnivorous animal which had either attacked the Brontosaurus
