When American start using the word dinosaur?

The Word "dinosaur" was first coined in 1842 by the British paleontologist Richard Owen, who used it to describe a distinct group of large, extinct reptiles. The term comes from the Greek Words "deinos," meaning "terrible," and "sauros," meaning "lizard." In the United States, the term began to gain popularity in the mid-to-late 19th century as fossil discoveries increased and public interest in Paleontology grew. By the early 20th century, "dinosaur" had become a common term in American culture, often associated with children’s education and popular media.
