Iguanodon was the first dinosaur to be named. Around 1840 a man named Gideon Mantell found a large tooth by the side of the road. It looked like the tooth of an iguana but it was much larger. They were then able to match the tooth with the rest of the skeleton that was found. Iguanodon means "iguana tooth".

Mary Ann Mantel discovered, or was believed to find the first dinosaur fossil in the 1800s. She found a tooth in apile of gravel by the side of the road, while her husband was on a house call. Her husband studied the tooth and was later found out it belonged to a dinosaur, or back then a giant herbivorous reptile.
The longest dinosaur is believed to be Argentinasaurus, which could grow to 110 feet.
The single biggest tooth? Or the genus of dinosaur that would likely have had the biggest teeth? If the latter, probably Carcharodontosaurus or Giganotosaurus.
Dinosaur fossils have been found throughout human history, but they have never been called dinosaurs or fossils. People thought they were the bones of dragons. The true investigation of dinosaurs began around 1840 when a woman found a large tooth in the ground. It was the tooth of an Iguanodon ("iguana tooth")
The dinosaur that lived the longest was the Brachiosaurus, which lived around 150 million years ago during the Jurassic period.
Diplodocus had the longest whip-like tail ever.
