Ctenogobius aff. boleosoma View in CoL ( Jordan & Gilbert, 1882)

Figure 42d–e View Fig

Material 2 specimens Gelasian , Moin FM , Atlantic Costa Rica, PPP 1772 ( NMB P15820-21 View Materials ) .

Discussion Two otoliths found in the Moin FM of Costa Rica resemble extant otoliths of C. boleosoma ( Fig. 42a–c View Fig ) but differ slightly in showing a deepened sulcus (vs shallow). Tey also do not show the widened pre- and postdorsal margins of the otolith, which appears to be typical for some Ctenogobius species. Terefore, and because of the inconspicuous overall appearance the fossil otoliths are only tentatively assigned to C. boleosoma .
