Stenotatus Ameghino

The genus is very like Prozaedius but differs in having thicker and wider movable plates, in having more rows of plates in the pelvic buckler (11), and in details throughout the skeleton. We found no representatives of the genus, but Ameghino has described a species (no figure), S. (Prodasypus) ornatus[22] based on isolated plates. A movable plate measures 18 mm. long by 6-7 mm. wide, while a fixed plate measures 9 mm. long, by 6-7 mm. wide.
