Left upper first molar discovered by K. A. Prufrock in matrix collected by John Storer and crew, RSM P3450.1466 (fig. 2A, 2E) .</p><p>Horizon and type locality. Interbedded conglomerate and coarse sandstone of Uintan middle Eocene age, Swift Current Creek locality, southwestern Saskatchewan, Canada (Russell, 1965a, 1965b, 1972; Storer, 1978, 1996).</p><p>Diagnosis. Approximately 30% smaller in linear dimensions than Trogolemur leonardi; buccal notch much shallower; greater development of lingual cingulum. Differs from Trogolemur myodes in M1 being wider relative to length, more pronounced lingual cingulum, much shallower buccal notch. Differs from Trogolemur amplior in being considerably smaller. Differs from Trogolemur myodes in m3 having much more taper distally, with long and narrow hypoconulid lobe. Differs from Trogolemur fragilis in having a less distinct paraconid on m3 that sits closer to the metaconid, slightly longer and narrower hypoconulid lobe.</p><p>Etymology. ‘storeri’ named for John E. Storer who described the first primates from the Swift Current Creek locality and in honor of his extensive contributions to Canadian paleontology.</p><p>Hypodigm. Lm3, RSM P3450.1467; Rm3, RSM P3450.1468.</p><p>Summary of Changes</p><p>The following list summarizes suggested changes to the record for the genus Trogolemur . • Trogolemur myodes USNM 417396 is an M1, not an M2. • Trogolemur leonardi RSM P 1899.1014 and RSM P1899.1016 are M3s, not M2s. • Trogolemur leonardi RSM P 1899.1007 is an M2, not an M1. • Trogolemur leonardi RSM P 1899.1002, RSM P1899.1003, and RSM P1899.1004, all identified as m1 or m2, are likely m1s.</p><p>New records of Trogolemur include a left M1 (RSM P3450.1466), a left m3 (RSM P3450.1467), and a right m3 (RSM P3450.1468). These are described as a new species, Trogolemur storeri . With very little morphological difference between Trogolemur storeri and Trogolemur leonardi apart from size, and with little geographic separation, it seems likely that the former is a phyletic antecedent to the latter.</p><p>New Discoveries – Walshina</p><p>An upper molar resembling Trogolemur leonardi, but approximately 50% larger in linear dimensions, was discovered in the SCC matrix (Figure 5). Slight erosion along the buccal and distal margins has altered the outline of the tooth. Nevertheless, this tooth (RSM P3450.1469) is recognizable as a primate right M1 (or possibly M2). The tooth has a broad basin distal to the protocone; this is distinctive of trogolemurin omomyoids. It greatly resembles CM 15635 (LM1) from the Uintan Badwater Creek, Wyoming. That tooth was originally described as Phenacolemur mcgrewi by Peter Robinson, then allocated to Ignacius by Bown and Rose (Robinson, 1968; Bown and Rose, 1976). Subsequent analysis by López-Torres and colleagues has shifted this material from the Paromomyidae (Plesiadapiformes) to the Trogolemurini ( Omomyidae), renaming the relevant material as Walshina mcgrewi (López-Torres, et al., 2018). We provisionally refer the new tooth to Walshina mcgrewi .</p><p>Given the rarity of primate material at SCC, it is interesting that there are two known species of trogolemurin omomyid at this locality. Thus, diversity of trogolemurins is slightly higher here than in contemporaneous faunas in Wyoming or southern California. Despite the enormous geographic separation, trogolemurins existed simultaneously in all these places. This speaks to the similarity in climate across much of North America in the middle Eocene, and/or to the adaptability of these tiny primates.</p></div>	https://treatment.plazi.org/id/03B387CDFFCA7F34FC72FBC115C8549F	Public Domain	No known copyright restrictions apply.

Saskomomys lindsayorum, new species . Figure 10. Tables 2 and 3.</p><p>Diagnosis. Differs from Omomys in being smaller in occlusal area of all compared teeth and in the following: p4 with indistinct metaconid, crest emitting from protoconid buccally oriented, linguallyseated paraconid, and short talonid that rises quite dorsally at its distal end; m1 and m2 narrower; m3 broader, with more rounded cusps, with paraconid located centrally; M1 less well-developed hypocone shelf; M2 more convex mesial margin and deeper notch at distal margin; M3 less triangular (i.e., more extensive hypocone shelf), relatively less extensive expansion of the base of the protocone lingually, lingual cingulum continuous or nearly so. Differs from Chumashius in having no distinct metaconid on p4, crest running from protoconid runs buccally rather than distobuccally, less lingually projecting paraconid; m1 and m2 narrower, less well-developed buccal cingulid; m3 hypoconulid lobe more isolated (i.e., constricted at its mesial end), trigonid longer at lingual side and more rounded mesially; M2 narrower (especially at protocone), greater extent of hypocone, more distinct conules, more distinct buccal cingulum. Differs from Dyseolemur in having less basal inflation and crenulation on the lower molars and in lacking a metastylid and the fovea separating the metastylid from the metaconid; m3 has more isolated hypoconulid lobe; M1 and M2 have smaller hypocone, conules, and buccal cingulum, with less-distinct crests emitting from the conules lingually; M3 has less-distinct buccal cingulum and is more triangular in outline (narrower at protocone than at buccal cusps). Differs from Ekwiiyemakius in having a shorter and broader p3 and m3; more constriction mesial to the hypoconulid lobe on m3; M1 buccal notch is more pronounced (deeper and narrower); M1 and M2 trigon basin and hypocone shelf are broader; M3 is longer (mesiodistal dimension).</p><p>aSee also measurements in Storer 1984 and Storer 1990.</p><p>Etymology. Prefix ‘ Sask– ’ in reference to the distribution of the taxon in the province of Saskatchewan. Suffix ‘– omomys ’ (Greek, “shoulder-mouse”) refers to omomyoid primates generally.</p></div>	https://treatment.plazi.org/id/03B387CDFFC67F3FFC4AF8CC14DA538C	Public Domain	No known copyright restrictions apply.
