Typical in dyrosaurids is a single nasal element with a characteristic collection of small pits and a constant width until it widens to contact the lacrimal bones, then tapering off for a short distance until it meets the boundary of the frontals and prefrontals [REF].
While both are species in the Dyrosaurus clade, D. maghribensis and D. phosphaticus have some difference, one of them being the shape and style of their osteoderm.
