The advent of the darwinian theory of evolution by natural selection in 1859 and subsequent studies of phylogeny based on the fossil record by haeckel, huxley, cope, marsh, and others did not lead to any real discussion of mass extinctions, nor of the extinction of the dinosaurs in particular, as issues worthy of explanation.
