Cretaceous

Case & Cappetta 1997 erected Anomotodon toddi for smooth-crowned teeth from the Late Maastrichtian of Texas. They deemed these teeth to be distinguished from other members of the genus by the smooth (unfolded, non striated) lingual crown surface. They went on to note that Welton & Farish (1993: 114, figs. 2-5) included this tooth-design as Paranomotodon. A similar Maastrichtian tooth was previously included on this website as A. plicatus (Fig. ).

Paleogene

When found in Mid-Atlantic exposures, the feature of these teeth, that most stands out, is its (usually) smooth, narrow cusp and the absence of lateral cusplets. Trying to make positional sense of variations of this simple design, the expertise of Steve Cunningham was employed. He tendered opinions as reflected in Figure .

In addition to A. novus, the Potapaco Bed B sediments of the Nanjemoy yield a second Anomotodon tooth-design, first recognized as such by Cunningham and Ward (pers. com. 1999). These teeth compare very well with those ascribed to A. sheppeyensis. Kent (1999) reported A. novus only from this fauna.

Case 1980 erected Anomotodon cravenensis for specimens recovered from the Trent Marl in North Carolina. These sediments were originally thought to be Miocene in age but have been subsequently moved to the Oligocene. A single example is known to the author recovered from Lee Creek tailings -- likely upper Pungo River. Because of its apparent rarity, this specimen may have been reworked into these Miocene sediments. Purdy et al (2001) made no reference to this taxon when describing this fauna.
