THE THREE-HORNED DINOSAURS 109<br />
<strong>The</strong> fore-limb and foot are shorter than the hind foot, and<br />
the bones much heavier, marked with strongly developed,<br />
roughened projections for the attachment <strong>of</strong> heavy muscles.<br />

unknown, b'lt the most reasonable one is that <strong>of</strong> a changing<br />
climate, to which these highly specialized reptiles were unable<br />
to adapt themselves.
