Cryptochiton stelleri also has a fossil record that extends as far back as, at least, 120,000 years. For over 35 years, I and my paleontology students have been visiting a 47,000 year-old, emergent marine-terrace locality near Goleta, west of Santa Barbara, southern California. During that time, we have found only three plates of C. stelleri. To my knowledge, no one has reported before that this chiton occurs in these particular marine-terrace deposits. One of the best preserved valves (width 5.3 cm) is shown below.
