Stratigraphy
Lithology and environment
| Primary lithology: | poorly lithified "volcaniclastic" |
| Includes fossils? | Y |
| Lithology description: These localities are characterized by outcrops of Tertiary to Quaternary volcanic and volcano− sedimentary rocks (INEGI 1992). The latter include un− named Quaternary fluvio−lacustrine deposits consisting of poorly to moderately consolidated clays and silts, which are irregularly intercalated with volcanic gravels of andesitic to mafic composition (Bravo−Cuevas 2002). The fossil material was recovered from these deposits (Fig. 2). | |
| Environment: | fluvial indet. |
Taphonomy
| Modes of preservation: | body |
| Size of fossils: | macrofossils |
Collection methods and comments
