Richard Owen was a British biologist and paleontologist, best known for his work in comparative anatomy. He was born on July 20, 1804, and played a significant role in the establishment of the Natural History Museum in London. Owen is credited with coining the term “dinosaur,” which means “terrible lizard,” to describe a group of large prehistoric reptiles. Owen's research contributed to the understanding of extinct species, including the Moa and the Dodo. He was also instrumental in the study of fossils and the development of evolutionary theory, although he had differing views from Charles Darwin. Owen passed away on December 18, 1892.
