Fossils of the Schoharie grit In chapter 7, 123 sjjecies of fossils are listed from this forma- tion. Of these 103 species have been found in the Schoharie. â Fig. 95 Rlilpidomella alsa region, the remainder being from Albany county. Of the total number, 43 pass upward into the Onondaga and sometimes higher, leaving a total of 77 species confined to this horizon. Of these the mollusks are the most striking, particularly the cephalo- pods, of which a total of 43 species are in- cluded in the list, 39 of which have not been recorded from higher horizons. Among the brachiopods the following may be noted : Rhipidomella alsa [fig. 95], distinguished by its long hinge line, more convex brachial valve with de- pression down the center, and bifurcating striae; S t r o p h e o d o n t a p a r v a [fig. 96], characterized in the mold by strong subangular costae, w^hich become grooved and in- creased by intercalation on the lower part; Leptostro- p h i a p e r p 1 a n a [fig. 97]; recognized by its flat sur- face, fine striae and diverging depressed lines in the mold of the beak of the pedicle valve; Strophonella Fig. 96 S11- o p li e o d o n t a p a r V a.
