Аннотация:Burrows of the predatory polychaetes Lepidenteron lewesiensis (Mantell, 1822) are first discoveredin the marine Upper Cretaceous (Upper Coniacian–Lower Santonian) of the Upper Don (Voronezh)Region. Bone remains and scales of bony fish belonging to Clupeocephala indet. were found in the burrows.The discovery of Lepidenteron lewesiensis burrows in the Voronezh Region expands the paleogeographic dis-tribution of this ichnogenus and ichnospecies in the second half of the Cretaceous and supplements ourunderstanding of the Late Cretaceous marine paleoecosystems of this region.
