The London Archaeopteryx was discovered in 1861.    In 1877 a second and even better preserved specimen was found in the same limestone in Solnhofn, Bavaria.   This second specimen had a head which also included a full set of reptilian teeth, thus greatly strengthening Huxleys claim that Archaeopteryx was the missing link between dinosaurs and birds.

This specimen was sold to the Humboldt Museum in Berlin.
