Diamond Valley Lake Local Fauna

CA: Riverside Co


Location of Diamond Valley LakeAge Mid/Late Wisconsin (Springer et al. 2009) Two suites of fossils were present. Radiocarbon dates from the deeper depths of Diamond Valley (but not from Domenigoni Valley) are 41,490 ± 1380 and 41,200 ± 2100 BP. Fossils from shallower depths of Domenigoni and Diamond valleys indicate deposition between about 12.5 and 13.5 ka based on a number of dates. A single specimen of Equus conversidens from a depth of 2166 m gave an electron spin resonance date estimated as 230 ± 60 ka (Springer et al. 2009).

The Diamond Valley Lake Local Fauna consists of fossils from 2646 localities within the Domenigoni and Diamond valleys (Springer et al. 2009) recovered during excavations for Diamond Valley Lake Reservoir.

It's unclear in some cases whether Spring et al. (2009) is using "cf." to include the genus as well as the specific epithet; for example, cf. Sturnella neglecta. I have listed such cases as "cf. gen."

The site is listed in the taxon accounts as Diamond Valley.
