Armoured fish ['Placodermi'] Size:XS: 25 x 20cm 18th June 1988Sketches of two types of extinct armoured fossil fish from the class Placodermi, active from the Silurian to Devonian periods. Side views of one whole fish and one head study, as if in life. Found loosely inserted in Recherches sur les poisons fosssiles tome 1, by Louis Agassiz (Neuchatel, 1833 1843), pp. 36 37. Agassiz's work was the first significant survey of fossil ichthyology and these rough sketches were probably made by someone using the book
