YALE's BIG DIN0sAUR'
Prehistoric Animal Sci Up in
 the Peabody Museum
It Is Nearly Thirty Feet Long, was Found in Wyoming, and is the Finer of the Only Two Specimens Known.

New Haven, May ''i hV hNSN " saur on the restorau~-, VT ~nlcr 'he entire geological department of Yale university has been at work for more than a year, was placed in position this week in the Peabody museum Of fale' Ii is a magnificent specimen of this pre- historic animal.
 The name of the beast IS made up or two Greek words, deinos. meaning ter rible, and sauros. meaining lizard. or the many strange forms of animal lire the dinosaur was perhaps the most wonderful not only in size. but also m variety. The animal. so the geologists say. hourished in the Jurassic and Gre taceous periods. and some, it Is said m the Traisic age. In variety they ranged from animals two feet in length which closely resembled in many ways modern specimens of bird life to the largest ter restial and semi i-aquatic reptiles that ever lived. Some of the specimens un- earthed resemble in a general way the crocodile. while others show in their bony structure. which they have left De- hind them, a remarkable resemblance to the modern ostrich. It was only quite recently that the foot tracks found on the shore of the Connecticut river, which for years puzzled seient- ists. were figured out to have been made by this same animal.
 Yale's dinosaur is of the variety nam ed claosaurus. It was discovered by J. B. Hatcher. now of the Carnegie mu- scum of Pittsburg, and party Of friends In 1891. while exploring for the late Prof. F., o. Marsh of Yale in Con- verse county. Wyoming. It proved a most fortunate find. for not only was the specimen in excellent condition. with all its parts intact, but it was all so an entirely new variety. There is but one other such creature in the mu- seums of the world, and that Is in Brus- sels. Belgium. MT. Hatcher was so careful in arranging it's removal that no part of the animal was injured in transportation.
 The task of mounting it was not an easy one. Parts of the animal were so firmly embedded in the sandstone rock that 1t was impossible to dig them out without injuring the specimen. As much as possible was removed and this mixed with mortar. making solid background of stone on which the ami mai stands out in bold relief. In reali- ty 1t Is encased in the same sandstone in which it was found. in which it died thousands of years ago.
 The entire length of the Yale animal is ,29 feet 3 inches. The height of the head above the base is 13 feet ? inches The height of the shoulders above the base Is ten feet. the length of the tai is 13 feet z inches. and the length oi the hind legs feet inches. It is mounted in a position of motion. with one hind foot lifted a bit from Sht ground, while the front limbs. which are considerably smaller than the hind limbs are in the air, showing that tht creature was in the habit of propellini itself with the hind limbs.

 The specimen is mounted in four set tions. each of which is on a truck whic IS In turn on castors. so that it can readily taken apart and removed other parts of the building. As 1t no stands in the center of the room, 1t O cupies space 20 feet long by l3 fe' high, and very little opportunity is gi' en to study 1t in the perspective. Whe the new addition to Peabody museum made 1t is expected that this specime will occupy space against one side the room where it will not interfei with other exhibits and where ig can ] studied better.
