This Embryology category shows media and pages related to the historic human embryo Klb. An early human embryo from the normal series of Keibel and Else. No. 3 in the Keibel and Elze Normentafel (1908), modelled by Kroemer (1903) and a partial set of tracings made by H. M. Evans is in the Carnegie Collection No. Template:CE5463.
