The days of a monophyletic Placodermi 'order' are long since gone. Nowadays they are a paraohyketic assemvlage of stem eugnathostomes. And I wonder if some derived placoderms, might actually be crown group members. Though I am no expert.

#Placoderms (from Ancient Greek πλάξ [plax, plakos] 'plate' and δέρμα [derma] 'skin')[1] are vertebrate animals of the class Placodermi, an extinct group of prehistoric fish known from Paleozoic fossils during the Silurian and the #Devonianperiods.
