FIGURE 2 in Systematics of the Lower Ordovician pliomerid trilobite Hintzeia, with species from the Great Basin, western USA

FIGURE 2. Section of stratigraphic column of Section G (see Adrain et al. [2009] for full columns of sections G and H) showing occurrence of species of Hintzeia in the Psalikilus spinosum and Hintzeia celsaora zones of the Tulean. This part of Section G is a succession of thin beds of intraclastic rudstone ("flat pebble conglomerate") and covered slopes. Note that the lithological symbol appears to the right of the beds because it is too large to fit inside them. Original sampling horizons of Hintze (1951, 1953) are indicated at the corresponding metreage of our (2009) remeasurement.
