skull, and arm bones, with several
teeth was found and presented to the
University of Denver. The creature
in life must have been seventy feet
long. Prof Lee of the University thus
writes of us: ''The specimen is a gift
to the university from John Keegan
of Flagler. The manner in which it
was found is interesting: One day a
Mexican herdsman rode into Flagler
and reported that his horse stumbled
and fell over long string of bones.
The man picked up one of the bones
and was surprised to find it as heavy
as stone. He carried a piece to the
town, and Mr.. Keegan saw that the
bones might be of scientific interest.
He drove to the place and found about
| twelve feet of the vertebral column
lying on the ground, as it had lain
through countless thousands of years.
| There it had been left when the rock
decayed from around it. About four
| feet of the tail was still embedded in
the solid rock. This was carefully dug
out, and the whole skeleton preserved
by Mr.. Keegan, who sent it to the uni
versity. Mr.. Keegan reports that
while the specimen was in his possess
sion it was examined by several geo.
logists. From them we learn that the
bones are from the uppermost creta-
ceous formation of that region. The
place of preservation was too near the
division between cretaceous and terti-
airy rock that they could not determine
the age. Further study, however,
shows that the reptile is a cretaceous
form. During the cretaceous time, not
on y the greater part of Colorado. but
the greater part of the western half of
the continent, was shallow sea, dot
ted here and there with islands,
Those clumsy, overgrown monsters
which we are familiar with as in hab-
itants of the Denver region, had reach

to pass out of existence forever as
soon as the new conditions were inau.

these reptiles forms we find the an
cestors of the modern serpents. Dur
