	PTERICHTHYODES (Site not responding. Last check: 2007-10-13)
		Pterichthyodes sont un genre des poissons de placoderm de la période dévonienne, maintenant tout éteint.
		Les pterichthyodes ont eu fortement les chefs blindés et les corps avant, alors que leurs extrémités de queue étaient découvertes.
		L'aspect des pterichthyodes est suffisamment réminiscent d'un animal moderne qu'ils sont un de la quelque espèce éteinte pour avoir un nom populaire : "scorpions de mer".

	PTERICHTHYODES (Site not responding. Last check: 2007-10-13)
		Pterichthyodes sind eine Klasse der placoderm Fische von der Devonianischen Periode, jetzt ganz ausgestorben.
		Die pterichthyodes hatten schwer gepanzerte Köpfe und vordere Körper, wann ihre Endstückenden freilegt wurden.
		Die pterichthyodes werden leicht von anderen placoderms durch ihr ungerades Flügel-wie Anhang unterschieden, in dem Flossen auf einem modernen Fisch gefunden würden -- ausschließlich sprechend, sind diese nicht Flossen, wie wir normalerweise an sie denken, die in einer anderen Gruppe Fischen das Actinopterygii entwickelten.

	Discover Hugh Miller -
		At the time, these fossils were among the very oldest vertebrate fossils ever discovered and they figured prominently in Agassiz's epochmaking work, "Fossil Fishes of the Old Red Sandstone".
		Several of them (including Pterichthyodes milleri and Coccosteus milleri) bear Miller's name down to the present day.
		His significance in this and other respects may be denied by Mr Mitchell, but it is frankly acknowledged by such authorities as Dr Mike Taylor, Curator of Vertebrate Fossils at Edinburgh's Royal Museum.

		The placoderms appear all over the world, but in time they were almost wholly restricted to the Devonian period the only major fish group to have so short a span.
		The acanthodians may have fed on plankton and small animals, while they themselves used their impressive arrays of spines to discourage larger predators.
		The mediumsized unarmored fishes were fed on by Cheirolepis and Coccocteus, which have been found with acanthodians and Dipterus in their stomachs.

		Weird they appear but adapted to the conditions applying millions of years ago.
		The Pterichthyodes had its head and shoulders encased in boxes of bone with its eyes and nostrils on the top of its head.
		Dipterus was a lungfish, which can survive out of the water - there are still three species of lungfish alive today.

		It is often referred to as 'Hugh Miller's Fish', although when he first found the fossil he thought it might have been a small turtle as the tail portion of the fish was missing.
		Fossils of Pterichthyodes have been found of varying sizes, which suggest that this fish bred in the lake and spent its whole life there.
		This is in contrast to another armoured fish called Coccosteus.

		It seems that this episode, which fascinated the scientific public over a century ago, is due for a reassessment in the light of current knowledge especially since a new element is found at the well-known scene, radioactivity.
		"Anomalous high radioactivity has been detected in Homosteus, a fish from the same Old Red Sandstone beds in which Pterichthyodes occur," writes Hans Kloosterman [11].
		Latter-day uniformitarians tend to explain the radioactive anomalies by differential absorption of radioactive elements posterior to deposition.
