The Fossil Beds of Alberta. 207 



I was so fortunate as to discover it in a deep gorge in the bad 

 lands below Happy Jack ferry, twelve miles below Steveville. 

 Only the skull was present. It is over six feet long. A huge 

 horn core crowned the top of the nose, which must have been 

 three feet long in life. Projecting behind were six horn cores, 

 radiating from the back margin, the longest ones being twenty- 

 six inches long. I believe the entire top of the head, crest and 

 horn cores were sheathed in horn. 1 also believe that this head 

 was used in life as a shield to protect the vital organs. The 

 skin was covered with small scales arranged like mosaic work 

 in a payment. When he was attacked by a carnivorous enemy 

 he stood at bay and presented this impenetrable armor of de- 

 fense. 



The most valuable specimen found in 1913 was the nearly 

 complete skeleton of a great carnivorous dinosaur. Mr. Lambe 

 has named it Gorgosanrus libratus. This specimen, the most 

 complete of any Cretaceous carnivore known, was found by my 

 second son, Charles M. The skeleton is nearly complete, with 

 the skull and lower jaws, with all the teeth present. The most 

 remarkable thing about it is that the front limb and the ven- 

 tral ribs are with it and in position, for the first time in a single 

 individual. Twenty-eight feet of the skeleton was found. The 

 hind limbs are ten and a half feet long; the feet themselves 

 over three feet long, armed with great claws, which were once 

 covered with horn. Terrible weapons, indeed! The jaws are 

 three feet long and armed with long, serrate-edged teeth, many 

 of which are six inches in length. The front limbs were ves- 

 tiges, twenty-three inches in length, with no apparent use. 

 The ventral ribs sheathed the abdominal wall.s as if hooped in 

 steel. 



Among the duck-bills was the wonderful hooded species, with 

 footed ischia. The head resembles that of a cassowary, the 

 remarkable crest extending high above the top of the head, so 

 the height was equal to the length. The footed ischia allowed 

 the reptile to rest on them when he squatted down on the hind 

 limbs. They indeed acted as a third leg, and not the tail as the 

 early paleontologists thought. I have proved him to be a 

 swimmer, in the "dinosaur mummy" my son George found in 

 Wyoming, in 1908. I also believe his natural pose was that of 

 a lizard. Mr. Barnum Brown, of the American Museum of 

 Natural History, made the discovery of a still more perfect
