Animals of the Past
*C
N
Prior to the emergence of paleontology and comparative anatomy as scientific
disciplines at the end of the 18th century, it was generally known that there were
species of animals that had disappeared completely. The term "extinction" originally
applied to the extinguishing of fires or erasing of one's debt. It was not until 1784
that the term extinction was used to denote the complete eradication of a species of
living being. In 1901, Frederic A. Lucas penned an overview of vertebrate animals
whose only evidence of being remained in fossil records. The book focuses
primarily on vertebrate animals, from fish to mammals.
