The specimen was collected in 1858 from the Woodbury Formation in New Jersey, USA, representing the first dinosaur species known from more than isolated teeth to be identified in North America. Using radiometric dating of bivalve shells from the same formation, the sedimentary rocks where the Hadrosaurus fossil was found have been dated at some time between 80.5 and 78.5 million years ago.Gallagher, W.B. (2005). "" Netherlands Journal of Geosciences, 84(3): 241.
