Stratigraphy
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: From Pleistocene marine terrace. Terrace is exposed about 15 ft above sea level. It is cut into fossiliferous sandstone of the Pliocene Purisima Formation. Radiocardbon dates from bivalve shells in this area yielded dates older than 39,000 years | |||||
Lithology and environment
| Primary lithology: | poorly lithified sandstone |
| Includes fossils? | Y |
| Lithology description: Original sand deposits are preserved at locality M1691 as pockets underneath and between large, rather flat boulders of calcareous sandstone - probably concretions weathering out of the underlying Purism Formation. | |
| Environment: | coastal indet. |
| Glacial or sequence phase: | transgressive |
| Geology comments: A Pleistocene terrace shellbed, hence transgressive. | |
Taphonomy
| Modes of preservation: | body |
| Size of fossils: | macrofossils |
| Articulated whole bodies: | some |
| Temporal resolution: | time-averaged |
| Spatial resolution: | parautochthonous |
Collection methods and comments
| Collection excludes: | some microfossils |
| Collection methods: | bulk,selective quarrying,sieve,field collection |
| Reason for describing collection: | paleoecologic analysis |
| Museum repositories: | UCMP,USNM |
| Collection method comments: Figured specimens at USNM, unfigured specimens likely at UCMP (transferred from USGS Menlo Park). | |
| Taxonomic list comments:Detailed and representative for macrofossil taxa | |
