The marker is made up of three panels near the sculpture of the Lophorhorthon group. This is the first of three panels.

Lophorhothon atopus
(Loh-FOUR-ah-thon ay-TOH-pus)
“Crested Nose”
Cretaceous Period (65- 144 million years ago)
Southeastern United States

This scene shows a family of Lophorhothon dinosaurs, as they may have looked millions of years ago when they roamed Georgia and the Southeast. Adults grew up to 35 feet and weighed 3 to 4 tons. They typically walked on two legs, but could get down on all four legs to eat and drink.

Lophorhothon belongs to the family of dinosaurs known as Hadrosaurs, commonly called duckbills because of their duck-like snouts. Hadrosaurs were herbivores, and most likely ate a variety of plants including tree foliage and ferns. Their mouths contained hundreds of teeth arranged in overlapping rows, which allowed them to easily clip and grind vegetation.

Lophorhothon has a large prominent nose crest, like many other Hadrosaurs. What was this bony part of the nose, and what purpose did it serve? It is still a scientific

puzzle. Did a larger feature rest on top of the bony nose? Was it covered in brightly colored skin? Male Hadrosaurs may have used a bright crest to attract a mate, just as modern birds do today. Lophorhothon may have used the nose as a type of calling horn.

Lophorhothon may have shared behavior with one of its better known Hadrosaur relatives called Maiasaura peeblesorum. Fossil nests containing juveniles are evidence that Maiasaura cared for their young. The Lophorhothon atopus adults may have cared for their young, too.

Caption: These Lophorhothon atopus fossilized bones have been discovered, enough to allow scientists to make an identification.

Lophorhothon fossils have been discovered in bits and pieces in areas of the Southeast that were covered in a Cretaceous ocean. How did this land animal end up scattered in the salt water depths? Scientists have learned Lophorhothons that died near the ocean were lifted from land by tidal action, carried out to sea, and then nibbled by sharks and other sea life.
