Figure 2.

Composite stratigraphic column of the Kaiparowits Formation, with stratigraphic positions of localities of described material marked by stars (blue star: The Blues field area; red star: Fossil Ridge field area). Vertical red line indicates the stratigraphic uncertainty range for these localities. Yellow star indicates the position of the Parasaniwa cynochoros [32] type locality. Black horizontal arrows indicate stratigraphic position of radiometrically dated bentonite layers, indicated in purple. Stratigraphic column modified from Roberts [49], Beveridge et al. [53] and Ramezani et al. [62].
