	Placodermi - Wikipedia, the free encyclopedia
		The Placodermi are armoured prehistoric fishes known from fossils dating from the late Silurian to the end of the Devonian Period.
		Their head and thorax were covered by articulated armoured plates and the rest of the body was scaled or naked.

		Placodermi is the name of a class of jawed fish that disappeared during the Devonian Period (between 408 and 360 million years ago).
		This class is regarded in the imaginary evolutionary family tree as the ancestor of all jawed vertebrates.
		This represents a new dilemma for the theory of evolution, because it appears that an organ as complex as the tooth emerged in a period far older than evolutionists had hitherto believed.

		A pelvic clasper may, however, be present in the fossil Placodermi.
		The Placodermi are characterized by a dermal armor consisting of a head armor and a thoracic armor.
		Placoderms have long been regarded as the sister-group of chondrichthyans, with which they share an eye-stalk (a small cartilage linking the eyeball to the braincase) and possibly a pelvic clasper.

		Placoderms were early jawed fish that lived in the Silurian and Devonain (439-362 Mya).
		The name placoderm means 'plated skin' and refers to the dermal armour of large plates that covered the head and trunk region of the majority of the taxa in the Class Placodermi.
		Although placoderms have been recorded from the Silurian of China, they do not become widespread until the Devonian, when they briefly became one of the most successful groups of fishes before their extincion in the end Devonian mass extinctinon event.

		The Placodermi (Placo-, scale; -dermi, skin) is a totally extinct group that flourished during the Devonian* period. However these fish did have paired fins and a heterocercal tail which suggests that they could swim quite efficiently.
		The extinct armored fishes known as placoderms make up what is considered to be the earliest branch of the gnathostome family tree -- the earliest branch of the jawed fishes.
