The fossils from the Old Rampart area examined previously in 1975 (see report A-75-1) have been restudied for inclusion in a Professional Paper and are listed as follows:
Franziceras cf. rudidium (Buckman) at U.S. Geol. Survey Mesozoic locs. 29737, 29739, 29742. [Note by R.B. Blodgett: species name misspelled in E&R report, should be ruidum]
F. sp. at Mesozoic loc. 29742
F.? sp. at Mesozoic locs. 29740 and 29737.
Psiloceras sp. at Mesozoic loc. 29737.
Amaltheus stokesi (J. Sowerby) at Mesozoic loc. 29340.
Franziceras and Psiloceras occur nearly worldwide in the basal Hettangian at the base of the Jurassic. Amaltheus occurs in the upper Pliensbachian of northwestern Europe and as far south as British Columbia in North America.
The localities listed above are described below. Unless you inform me otherwise the fossil identifications, age determinations and locality descriptions are written herein will be used in a publication. |
