I thought this might have been deer hair at first, but it seemed more like some sort of shell when I flipped it (the white part). But I couldn't tell what they might have belonged to. Most of the nearby trees were oak.

Chlorogalum pomeridianum, the wavy-leafed soap plant, California soaproot, or Amole, is the most common and most widely distributed of the soap plants, soaproots or amoles, which make up the genus Chlorogalum of flowering plants. It is occasionally known as the "wild potato", but given the plant's lack of either resemblance or relationship to the potato, this name is not recommended.
