Lophorhothon

Name: Lophorhothon.
Phonetic: Lo-for-rho-fon.‬
Named By: W.‭ ‬Langston‭ ‬-‭ ‬1960.
Classification: Chordata,‭ ‬Reptilia,‭ ‬Dinosauria,‭ ‬Ornithischia,‭ ‬Ornithopoda,‭ ‬Hadrosauroidea‭?
Species: L.‭ ‬atopus‭ (‬type‭)‬.
Diet: Herbivore.
Size: Holotype roughly estimated at about‭ ‬4.5‭ ‬meters.

Time period: Campanian of the Cretaceous.
Fossil representation: Partial remains.

       Lophorhothon was first discovered in the US state of Alabama in the Mooreville Chalk Formation.‭ ‬During the Cretaceous,‭ ‬this area was known as a region of Appalachia‭ (‬the eastern landmass of North America at the time separated from Laramidia in the West‭)‬,‭ ‬and what is significant about this is that when Lophorhothon was described it was thought to be a hadrosaurid dinosaur,‭ ‬and was the first such dinosaur of its kind to be discovered in Appalachia.‭ ‬Since this time other researchers have preferred to class it as an iguanodont,‭ ‬and occasionally a hadrosauroid‭ (‬close to but not quite a hadrosaurid‭)‬.‭ ‬In‭ ‬2016‭ ‬a new genus from the same Mooreville Chalk Formation as the holotype individual of Lophorhothon was named as‭ ‬Eotrachodon,‭ ‬and this is identified as a full hadrosaurid dinosaur.‭ ‬Regardless of whether Lophorhothon becomes known as a full hadrosaurid again or not,‭ ‬we at least now are certain that hadrosaurid dinosaurs,‭ ‬and not just closely related forms,‭ ‬were at least present in Appalachia.
