Pseudoangustidontus (meaning "false Angustidontus") is a genus of hurdiid (peytoiid) radiodont from the Lower Ordovician of Morocco.[2][3] This genus is known from two described species, P. duplospineus and P. izidigua, with some specimens that are hard to determine which species to belong to.[1] This animal is only known from the Fezouata Formation, a fossil site in Morocco that is of Lagerstätte status, meaning that the fossils from this site are exceptionally preserved.[4] Because of its partial remains, its classification was debated, but with more complete fossils it is identified as radiodont frontal appendage.[1]
