re: Paleontological resources for the Midland Plaza Project (7178)
Dear Stephen:
I have conducted a thorough search of our paleontology collection records for the locality and specimen
data for proposed development at the Saint Agnes Medical Center Campus and Emergency Department
Optimization Project, area as outlined on the portion of the Fontana USGS topographic quadrangle map
that you sent to me via e-mail on June 6, 2022. We do not have any fossil localities that lie directly within
the proposed project area, but we do have fossil localities in the area from the same sedimentary deposits
that occur in the proposed project area, either at the surface or at depth.
The following table shows the closest known localities in the collection of the Natural History
Museum of Los Angeles County (NHMLA).

This records search covers only the records of the NHMLA. It is not intended as a
paleontological assessment of the project area for the purposes of CEQA or NEPA. Potentially
fossil-bearing units are present in the project area, either at the surface or in the subsurface. As
such, NHMLA recommends that a full paleontological assessment of the project area be
conducted by a paleontologist meeting Bureau of Land Management or Society of Vertebrate
Paleontology standards.
Sincerely,
Alyssa Bell, Ph.D.
