Recently Mori et al. (2016) published a paper describing a new tax- on of hadrosaurid dinosaur from the Upper Cretaceous Prince Creek Formation of the North Slope Alaska, a rock unit that has recently proven to be a productive source of scientific insights into the work- ings of an ancient Arctic terrestrial ecosystem (Fiorillo and Gangloff 2001; Gangloff et al. 2005; Fiorillo et al. 2009, 2010; Gangloff and Fiorillo 2010; Flaig et al. 2011, 2013, 2014; Fiorillo and Tykoski 2012, 2014). Although thorough testing of the systematics of this proposed taxon will occur over the next few years, one statement in the Mori et al. (2016) paper warrants comment now
