In Diracodon, Stegosaurus, and Dacenlurus (Omosaiirus)we know that the end of the tail was protected by a double rowof spines, while the anterior caudals and all the other vertebrsesupported one median row of high plates, which in consequenceof their abrupt posterior margin were pointed somewhat backwardsand formed an acute dorsal Fig. 6.—One pair of dermal caudal plates of Polacanthtis (preserved united inmatrix), side view. The probably complex armour of the Ceratopsidse is altogetherunknown, and the same is true for AcantJiopholis and Scelidosaurus, ITylcBosmirits is the only European armouredOrthopodous Dinosaur in which the armour is still partly m situ, andthough somewhat disturbed, one can notice that this Dinosaurpossessed at least two rows of lofty spines which, beginning directlybehind the head, inciease rapidly in height and attain their maximumdevelopment and sharpness in the scapular region. This remindsone to a certain degree of the armour of the Iguana lumbar region of Hylceosaurus is nearly unknown, and in thetail only button-like ossifications seem present. Turning back to Folacautlins, the piece figured by Ilulke andfragments which I succeeded in uniting prove that some of the roof-like plates and button-like pieces belong to th
