No. Date. 



vesiciilaris Lam.; Inoceramus fragilis H. & M. ; Pinna petrina 

 White; Rostellites mnJ)igua Stauton ; Buchiceras swallovi Shu- 

 mard ; Sphcnodisciis lenticulare Oweu ; Placcnticeras placenta 

 DeKay; Placcnticeras costata H. & J.; Pholadomija f<iihvcntri- 

 cosa; ScapMtcs nodosus M. & H. ; Scaphites sp. [The descrip- 

 tion of locality is vague. The Scaphites probably are from 

 near the middle of the Maucos shale.] 



The upper part of the "Prieta series" contains marine shells 

 said to be of Fox Hills age and fossil plants "not identifiable 

 with familiar Laramie species." The following fossils were 

 collected from these coal-bearing rocks in the Rio Puerco, 

 Hagan, and Tijeras fields : Ostrea prudentia White ; Ostrea 

 franMini Coquand ? ; E.rof/ijra tcxana Roemer; Exogyra win- 

 chelli White; Mactra pulcliella H. & J.; Tellina (1) pcrlata 

 H. & J.; Tellina equilateralis Meek; Idonarca (1) deprcssa 

 White; Cardium pauperculum Meek; Gardiutn sp. ; Legumen 

 (?) oppressum Conrad; Chcnniitzia coalvillcnsis Meek; Gyrodes 

 deprcssa Meek; Pyropsis hairdi M. & H. ; Rostellites dalli Stan- 

 ton; Valutomorpha (1) nova-mexicana H. & J.; Harpa (1) oc- 

 cidentalis H. & J.; Baculites aspcr Morton; shark's teeth; plants. 

 (P. 17) Tertiary beds "with remains of vertebrates which we 

 presume to be representatives of lower Tertiary strata" lie 

 stratigraphically above the coal-bearing rocks on the Rio Puerco.

This paper supplements to some extent the information given 

 in the description of the Albuquerque sheet (p. 338). A section 

 measured east of Prieta Mesa is given, in which the Cephalopod 

 zone is placed only about 100 feet above the Trcs Mermanos 

 sandstone (this Cephalopod zone seems to be the Concretion 

 zone of Herrick and Johnson). The coal-bearing sandstones 

 and shales (Mesaverde) are about L600 feet thick and are 

 overlain by Tertiary.

New Mexico. Int. Mg. Cong., 4th session, Proc, pp. 61-G4. 1901. 

 (P. 64) Attention is called to the fact that some of the New 

 Mexico coal-bearing rocks formerly supposed to be Laramie 

 contain Ostrea glatra and are overlain by marine Cretaceous 

 beds "with fossils like those of the upper Fox Hills group."
