What reading level is Osteology of Pteranodon book?
To quickly assess the difficulty of the text, read a short excerpt:
In the second dorsal, however, the capitular processes are given off from the centrum at a slightly higher level. The third centrum is united to the second without the aid of exapophyses. The slender anchylosed rib which it supports is still of the double-headed form, but the capitulum is situated so high up on the centrum that the foramen enclosed by the two branches of the rib is greatly reduced in size. The centra of the five succeeding vertebrae, the fourth, fifth, sixth, seventh, and eight...h of the notarium, progressively diminish in breadth until they become nearly circular in section, being constricted in the middle and expanded at the ends. Toward the end of the series, the fusion of the centra is possibly a little less complete, and in one specimen, No. 2699, the fifth and sixth vertebras were found slightly displaced, the exposed ends showing anteriorly a cup and posteriorly a reciprocal convex articular surface. The zygapophyses, too, which are completely fused anteriorly, appear less thoroughly united toward the rear end of the notarium.
