FIGURE 25.-RESTORATION OF THE PALAEOSCINCUS, A CANADIAN DINOSAUR. A huge and slow-moving reptile with massive armor, designed for protection against the gigantic carnivorous dinosaurs. Restoration by E. M. Fulda, 1921.-After Matthew. 78
THE ARMOURED DI?\OSAGRL-\ shortened and at the same time much broader, was borne over similar neural spines on the anterior third of the tail. Here the character of the nueral spines abruptly changes, the broadened summits being lost and the whole spine very much reduced in height. This point, which marks the beginning of the aggressive, flexible portion of the tail, marks also an abrupt .--------:- -------- L FIGuRE 26. Three modern lizards which, save in their diminutive size. are suggestive of the Palaeoscinus of the Cretaceous Period. The "horned toad" to the left is nearest in proportions. The "spiny lizard" in the center and the "Moloch lizard" to the right also have some points of resemblance. The figures are about two.-thirds natural size. Were the little modern lizards as large as a hippopotamus, they would be monsters almost as strange as the long·extinct armored dinosaurs.-After Matthew. change in the character of the plates, which are now sharpedged, pointed and bent backward, the base being el:>bedded in the muscles between the neural spines and the vertc:l-,ral centra. The sharp-edged plates, of which there are three palt·". are followed by four pairs of long spines similarly attached and pointing outward and backward at a decided angle. The longest of these is 2S inches and its present weight 1474 lbs." 79
