The first dino discovered was a Megalosaurus by William Buckland. Scientists hypothesize that mostly all the dinosaurs were first - all born at the same time.
I found this: "A report of this find was published by R. Brookes in 1763. The first dinosaur to be described scientifically was Megalosaurus in 1824, by William Buckland. Buckland (1784-1856) was a British fossil hunter and clergyman who discovered some Megalosaurus fossils in 1819 and named the reptile in 1824."

Hope this helped!! :D

Have a wonderful lovely happy day :)
