Lateral views of USNM 1201 and USNM 2142.

<p><b>A.</b> Left lateral view of USNM 1201, originally named the holotype of <i>Triceratops</i> ‘<i>elatus</i>.’ Note that the ventral extremity of the squamosal (denoted by upper horizontal line) is positioned well above the alveolar process of the maxilla (denoted by lower horizontal line). <b>B.</b> USNM 2412, right lateral view (reversed for direct comparison with USNM 1201 which only preserves the left side of the skull; the right squamosal of USNM 2412 is more elevated than the left). The alveolar process of the maxilla is positioned on the lower horizontal line, allowing for a direct comparison with USNM 1201. Note that the squamosal is not elevated to the extent found in USNM 1201. The position of the ventral extremity above the alveolar process of the maxilla can thus not be used to distinguish ‘<i>Nedoceratops hatcheri’</i> from <i>Triceratops</i>. Scale bars equal 10 cm.
