Astrodon is an extinct genus of large herbivorous dinosaurs that lived during the Early Cretaceous period, about 112 to 97 million years ago. It was a member of the Sauropod family, which includes some of the largest land animals ever. Astrodon had a long neck, large body, and a bulky tail. It walked on four thick, column-like legs and had small arms with four fingers. Its head had small, peg-like teeth that were used to strip leaves and branches from trees. Its skin was covered in small, bony plates, similar to those of an armadillo. Astrodon was likely a browser of low-lying foliage, using its teeth to strip branches and leaves from trees. Its size likely offered it some protection from predators, as well as providing it with a good vantage point to survey its environment.

Astrodon is a genus of herbivorous dinosaurs that lived during the Early Cretaceous period, around 125 to 112 million years ago.
The type species, A. johnstoni, was first discovered in Maryland in 1858 and is the only species of Astrodon known to science. The other species, A. montanensis, was discovered in Montana in 1873 but never formally described.
Astrodon is a member of the family Hadrosauridae, which also includes such dinosaurs as Edmontosaurus and Saurolophus. Astrodon is most closely related to the genus Gryposaurus, which is also found in North America during the same time period.
Astrodon was a large quadrupedal herbivore with a long neck and a relatively short tail. It had a wide, flattened head and a wide muzzle, with a shorter snout than its close relatives. Its teeth were adapted for grinding plant material, and its beak was likely used for cropping vegetation.
Astrodon was a typical hadrosaurid, meaning it was part of an evolutionary trend that saw the development of larger and more complex body forms. Its size and shape indicate that it was well-adapted for life in open, flat environments and was likely an excellent runner.
Astrodon is the only known species in its genus, its close relatives include Gryposaurus and Edmontosaurus. These genera are thought to have evolved from a common ancestor, showing the evolutionary relationship between them.
Astrodon is also thought to have had a close relationship with Saurolophus, another hadrosaurid found in North America.
The Astrodon dinosaur is a genus of large herbivorous sauropod dinosaurs that lived in what is now North America during the mid to late Cretaceous period (about 95 to 65 million years ago). Astrodon was a long-necked, quadrupedal dinosaur that grew to an estimated length of up to 40 feet (12 meters) and weighed up to 12 tons.
Astrodon was an important part of the North American dinosaur fauna during the Cretaceous period and likely played an important role in the food webs of that time. However, like many other dinosaurs, Astrodon eventually went extinct during the mass extinction event at the end of the Cretaceous period.
The cause of the mass extinction at the end of the Cretaceous period is still a matter of debate, but the most widely accepted theory is that a large asteroid or comet impacted the Earth and caused global climate change that wiped out many species, including the Astrodon. Other factors that may have contributed to the extinction of the Astrodon and other dinosaurs include volcanic activity, sea level changes, and changes in the atmosphere. Regardless of the cause, the extinction of the Astrodon and other dinosaurs marks a major shift in the Earth's history, as it paved the way for the rise of mammals and ultimately the emergence of humans.
