This view is consistent with observations of lungfish dental anatomy, including Tomes (1882), Peyer (1925), Bemis (1984), and Smith & Krupina (2001), all of whom noted the sustained growth and redeposition of dental plates in Dipnoi
Albeit there are those latterday scientists who would tend instead to award the ancestral palm to the lung-fish (Dipnoi

Indeed, these three copies of Aqp2 are thought to be basal forms of the triad of Aqps (Aqp2, -5, and -6) otherwise found in land animals (Dipnoi
, lungfish also have single copies of Aqp2; Finn et al., 2014).
The North American fossil record of Cretaceous Dipnoi
is scant, with few reports from the Cenomanian other than Ceratodus gustasoni from the Dakota Formation of southern Utah (Kirkland 1987).
