What reading level is Republication of Conrads Fossil Shells of the Tertiary Formations of North Amer book?
To quickly assess the difficulty of the text, read a short excerpt:
) Calyptrea trochiformis, (Lam. ) Pyrula tricarinata, (Lam. ) Acicula trigona, (Lam. ) Cytherea erycinoides, (Lam. ) C. Subery- cinoides, (Desh. ) Corbis lamellosa, (Lam. ) Cardita planicosta, (Blain. ) Fistulana elongata. (Desh. ) 8. A mass of Ostrea selheformis, about three feet in thickness, in sand cemented by carbonate of lime. As this oyster also oc- curs in the newer Cretaceous strata, at first I supposed the present to be of the same age . As the latter deposit, but a subsequent ex- ami...nation of the inferior stratum convinced me to the contrary, as I found it characterized by Eocene fossils exclusively. Large specimens of the Ostrea generally have a water worn appearance, and occur mostly in single valves ; the young which are vastly abundant are also disunited, but invariably uninjured and unworn. Fragments of this rock form a talus at the base of the escarpment.
4. A dark colored marl, seventy feet in thickness, in which the same Ostrea occurs, but smaller and less abundant than above.
