Richard Lydekker (25 July 1849 – 16 April 1915) was a British naturalist, geologist and writer of numerous books on natural history. He was known for his contributions to zoology, paleontology, and biogeography. He worked extensively in cataloging fossil vertebrates and describing new species, particularly from India, where he spent several years studying the region's prehistoric fauna.
Lydekker was a key figure in the field of vertebrate paleontology, authoring numerous scientific papers and books that helped classify extinct and extant species.
Biography
Richard Lydekker was born at Tavistock Square in London. His father was Gerard Wolfe Lydekker, a barrister-at-law with Dutch ancestry. The family moved to Harpenden Lodge soon after Richard's birth. He was educated at Trinity College, Cambridge, where he took a first-class in the Natural Science tripos (1872). In 1874 he joined the Geological Survey of India and made studies of the vertebrate palaeontology of northern India (especially Kashmir). He remained in this post until the death of his father in 1881. His main work in India was on the Siwalik palaeofauna; it was published in Palaeontologia Indica. He was responsible for the cataloguing of the fossil mammals, reptiles, and birds in the Natural History Museum (10 vols., 1891), where he worked in an honorary capacity for the rest of his life.
He named a variety of taxa, including the golden-bellied mangabey; as a taxon authority, he is named simply as "Lydekker".
Biogeography
He was influential in the science of biogeography. In 1896, he delineated the biogeographical boundary through Indonesia, known as Lydekker's Line, that separates Wallacea on the west from Australia-New Guinea on the east. It follows the edge of the Sahul Shelf, an area from New Guinea to Australia of shallow water with the Aru Islands on its edge. Along with Wallace's Line and others, it indicates the definite effect of geology on the biogeography of the region, something not seen so clearly in other parts of the world.
