Example: "The geologist collected a hand sample of the rock to study its mineral composition."
Alternatives: "a physical sample" or "a representative sample".
The fossil humeral remains are specifically attributed to Icaops aenae because of the depositional association of the humeral fragment QM F30573 with I. aenae craniodental remains (QM F30584, a left dentary containing m2 and m3, and QM F30575, an M1) preserved less than 15 cm away in a hand-sample of limestone collected from Wayne's Wok Site in which the dentary was partially exposed.

These subjects (within gender with handshake) shifted in right shaking hand sampling from an expected −5.39 ± 15.29 s (expected = change following no-handshake greet) to 2.14 ± 8.1 s (change following handshake greet), that is, a 135.99% increase.
These subjects (across gender with handshake) shifted in left non-shaking hand sampling from an expected −7.95 ± 28.33 s (expected = change following no-handshake greet) to 2.91 ± 11.84 s (change following handshake greet), that is, a 139.24% increase.
