Orthoceras parallelum Rome, Mammal, pl.511. Fig.712, May be same thing as my Large Cymatostata, and as parallelum of Hall if several folds + small mid ridge are due to crushing, shows tendency toward rhythmic folds. Pl. 82 fig. 74, parallelum is a much better specimen than a figure suggests - Cymatostata marked vertically as so to be more convinicing. Palaezoic, Mordidysus aurantius Pl. 82 fig. 3 c. (Bradman) Like any Cummings from Channel, no sharp midline ridge; Mordidysus curtus, Girty. pl. 81 fig. 4, Dactyrodonta like those I collected. No natural ridge. (45) Mordidysus curtus, pl. 82 fig. 2 a Girvine = Small Oterinea dermis fairly well. at any rate it looks like Oterinea to me at break slices and as much of structure as one left. And then to make the striae go obliquely forward as well as upward, and return to central ridge they go vertically upward. Diphyspira athreniata. sharp, angularity relations but no detail in fig 2 a, pl. 83. I think fairly. Olenus music (Clothospira) outcrop pl. 83 fig. 3 d = genuine. fig 3 c with inferior angula tilt with slight bend on the inside of greatest lateral extension of shell = partially genuine but needed to watch. Notice angulation half way down inner slope of last whorl, Camarospora petelloformis good like mine with median angularity trim. Palaezoic, Byssinoclae.
