Klaus Jürgen Müller (born 6 February 1923 in Berlin, died 12 March 2010 in Bonn) was a German paleontologist.
In 1956, he described the Devonian conodont genus Palmatolepis.[1]
In 1959, he described the Cambrian conodont genera Furnishina, Hertzina and Westergaardodina, and the conodont family Westergaardodinidae.[2]
In 1962, he described the conodont order Paraconodontida.[3]
In 2003, he was awarded the Pander medal by the Pander Society, an informal organisation founded in 1967 for the promotion of the study of conodont palaeontology.
The conodont genus name Muellerilepis Bardashev & Bardasheva (2013) is a tribute to K.J.Müller. It is replacement generic name for Muellerina Bardashev et Bardasheva, 2012,[4] which is a preoccupied name.
