e researches of geologists throughout
the Rocky Mountain region. I doubt not that many hundreds of tons will
eventually be exhumed." Rather a startling prophecy to make within
eighteen months of their discovery, but it was hardly exaggerated.

It is impossible to say which of these three observers actually made
the first discovery of Jurassic dinosaurs; whatever doubt there is is
in favor of Mr. Reed.

Professor Lakes, accompanied by his friend Mr. E.L. Beckwith, an
engineer, was, one day in March, 1877, hunting along the "hogback" in
the vicinity of Morrison, Colorado, for fossil leaves in the Dakota
Cretaceous sandstone which caps the ridge, when he saw a large block
of sandstone with an enormous vertebra partly imbedded in it. He
discussed the nature of the fossil with his friend (so he told me) and
finally concluded that it was a fossil bone. He had recently come from
England and had heard of Professor Phillips' discoveries of similar
dinosaurs there. He knew of Professor Marsh of Yale from his recent
discoveries of toothed birds in the chalk of Kansas, and reported the
find to him. As a result, the specimen, rock and all, was shipped to
him by express at ten cents a pound! And Professor Marsh immediately
announced the discovery of _Titanosaurus_ (_Atlantosaurus_) _immanis_,
a huge dinosaur having a probable length of one hundred and fifteen
feet and unknown height. And Professor Lakes was immediately set at
work in the "Morrison quarry" near by, whence comes the accepted name
of these dinosaur beds in the Rocky Mountains. Professor Lakes once
showed me the exact spot where he found his first specimen.

Mr. Lucas, teaching his first term of a country school that spring in
Garden Park near Canyon City, as an amateur botanist was interested in
the plants of the vicinity. Rambling through the adjacent hills in
search of them, in March, 1877, he stumbled upon some fragments of
fossil bones in a little ravine not far from the famous quarry later
worked for Professor Marsh. He recognized them as fossils and they
greatly excited, not only his curiosity, but the curiosity of the
neighbors. He had heard of the late Professor Cope and sent some of
the bones to him, who promptly labelled them _Camarasaurus supremus_.

The announcement of these discoveries promptly brought Mr. David
Baldwin, Professor Marsh's collector in New Mexico, to the scene. Only
a few months previously he had discovered fossil bones in the red beds
