Taxonomic list comments:identical to list 6 of Williamson 1996 several records are omitted by Williamson and Lucas 1993 it appears that there are also Torrejonian strata in Gallegos Canyon ("Chico Springs"), represented in AMNH collections; some i.d.s separated out as a second list (see) multiple localities from a single 1 m thick black sandstone; virtually every specimen is from a different UNM locality section is entirely reversed, hard to correlate to paleomag time scale as base should encompass 29N; possibility that the entire section represents 29R is not discussed |
