New Haven, Conn. - The only
mounted skeleton in the world, SO
tar as scientists know. Of the Stego-
paurus ungulatus, or armored dina
gaur. 10 now on exhibition at Yale
Peabody museum. He Is a cousin, SO
TO speak, Of the huge trachodon
(clausaurus), who also has quarters
ID the museum. At present he weighs
l.e17 pounds, but when 5000 years
lgo he wandered around Lake Como,
In Wyoming, he tipped the scales
somewhere between seven and ten
tons.
For some 80 years his bones have
bsen stored in the basement Of Pea
body museum, for it was in 1879 that
be was unearthed In Wyoming by w.
Il. Reed and A. Lakes and was pre-
sented to Peabody museum by the
late Prof. Othniel G. March. Hugh
Glib and w. s. Benton Of the museum
star have been at work on the restora-
lion for several months and, accord
Ing to experts, Stegosaurus ungolatus,
now that he is in position, is n Of
the finest specimens of restoration in
the country.
This latest addition to the museum
besides being the most %grotesQue men,
Der of the reptile family ever set up
there. has the distinction of having
the smallest brain in proportion to It's
size Of any vertebrate " known to
the Yale scientists. His brain In life,
according to their reckoning, weighed
about two and one-half ounces, one
nftieth the weight of the brain of a
modern elephant Of far less bodily
weight.
The defensive armament of the d.
nosaur was his most startling charac-
thristic. This consisted Of a double
row Of upright bony plates along the
neck and proximal part Of the tail.
According to the Yale scientists he
probably fought his enemies with his
tail and with his back to the foe. He
had q long flexible tail with pointed
spines borne toward the end, and by
swinging this tail probably impaled
his enemies on the .sharp-edged plates.
According to Prof. Richard 8. Lull, the
vertebrate paleontolog1st at Yale, a
fight between stegosaurus and his
arch enemy, %allosaurus, would have
been a wonder.
Some idea of the formidableness of
bis tail may be gained when 1t is reck-
oned that its perpendicular length is
nine feet and the height of the tail tip
four feet one and one-half inches. The
size Of the highest plate is eleven
feet ton and one-half inches. while the
length Of the skeleton between per-
p~endiculars is nineteen feet five
inches. The width of the hips is less
than three and one-half feet, and the
width Of the chest Is three feet eight
and one-half inches. The greatest
width ts at the shoulders, where the
measurements are three feet ten and
one-half inches.
Both plates and spines were sheath
ed with horn, according to the Yale
scientists. The form Of the body is
accumulated by the peculiar shape Of
the vertebrae upon which the attach
ments for the ribs are elevated to an
unusual degree, giving the lank frame
greater interior capacity and at the
same time providing a wonderful me-
chanical device for the support of the
armor plate.
6tegosaurus was found exclusively
in Wyoming and Colorado in the lower
cretaceous or Morrison beds. 1t is
thought that stegosaurus was a forest
dweller, and on account of the struc-
ture Of the mouth lived on palms
and ferns and other tender tropical
vegetation Of the day.
Prof. Lull in the American Journal
of Science has the following to say
about Yale's latest addition:
Some Of the most notable anatom-
ical features are the remarkable
proportions Of the animal with the
sharply arched vertebral column,
short neck. small head, lank, narrow
body and extremely long limbs. The
tail, which did not droop abruptly, as
represented In all pervious restora.
lions, was evidently held high above
the ground, and gives evidence espe.
cially In its posterior halt, of extreme
sinuous h~exibility. and armed as It
Wal with sharp-edged plates and
spines. was the principal weapon OF
ofense and defense against the san.
culinary carnivores Of that day.
"Of the evolutionary history OF
stegosaurus we know but little. II
seems. however, to have been a mi
grant from Europe. In Omasaurus
durobrivensis from the Oxfordian Of
England which l studied this summer
at Cambridge and in the British MI
ssum Of Natural History, l find what
may readily be a direct ancestor Of
the American types"
