What reading level is The Fauna of the Pottsville Formation of Ohio Below the Lower Mercer Limestone book?
To quickly assess the difficulty of the text, read a short excerpt:
, convexity 6. 5 mm.
74 Remarks. This species of Naiadites has been found at one local- ity in Scioto County where it is not only extremely abundant, but the specimens are often in a remarkable state of preservation, a condi- tion very unusual for the representatives of the genus. The general condition of occurrence of Naiadites in the Pottsville rocks of Ohio is crushed, distorted, or macerated. The species under discussion occurs in nodules of iron ore and is associated with N. Elongata, but ...no other fossils are present. N. Elongata differs in having a shorter hinge line which is equal to less than one-half the length of the shell; also in its rounded posterior margins and its less prominent umbonal ridge. N. Ohionese, however, is very variable and differences exist in the size and prominences of the anterior lobe, the length of the hinge line, and the outline of the posterior portion. Whether these points of difference are due to slight distortion or natural variation among individuals, or whether more than one species is really present, is a matter of question.
