Life in the Valjevo Lake during the late early Miocene, Valjevo Formation. The individual reconstructions aim at visualizing the external meristic and morphometric characters, including the head shape and proportions, as well as dentition: aKlincigobius (slender body and head shape, the latter with depressed dorsal profile; snout inferior, long, and with curved canine teeth). bRhamphogobius (short body with broad head, short snout, few canine teeth anteriorly and predominantly columnar teeth laterally, and beak-like tip of dentary). cToxopyge (moderately slender body shape and head, curved maxilla facilitating wide mouth opening, many canine teeth). d Visualization of the lives of the three gobiid genera in their putative natural habitat: Klincigobius (ambush predator partly hidden in sand), Rhamphogobius (agile small fish hiding in freshwater vegetation and feeding on small crustaceans), and Toxopyge (suck-in predator in ambush position)
