Scientific Facts About Apatosaurus

  • Othniel Charles Marsh first described the Apatosaurus in 1877 and gave it the scientific name Apatosaurus ajax.
  • Paleontologists believe the Apatosaurus had to eat about 800 pounds of food a day to meet their energy demands.
  • There are two recognized species of Apatosaurus, the Apatosaurus ajax (type species) and the Apatosaurus louisae.
  • It’s believe the Apatosaurus would sometimes swallow food whole and have to swallow rocks to aid their digestion.
  • Apatosaurus was a herbivore. Its diet was based on low-lying plants and potentially on the soft leaves from the tall trees.
  • Apatosaurus had chisel-like teeth, but it didn't use them for chewing. Instead, it consumed stones along with plants to facilitate grinding of food in the stomach.
  • Based on the footprint found in 2008, scientists concluded that hatchlings and young apatosauruses were able to run on the hind legs to keep the pace with the rest of the herd and escape from the predators.
  • Apatosaurus had very thick neck which was relatively "light" thanks to the system of air sacs in it. Flexibility and actual position of Apatosaurus neck (parallel to the ground or upright?) are still a mystery.
  • An adult Apatosaurus probably didn’t have to worry about predators due to its large size. Only a group of large apex predators, like an Allosaurs hunting group, could attempt to takedown a full-grown Apatosaurus.
  • Name "Apatosaurus" is reserved for the scientific community. It means "deceptive lizard" and it refers to the morphological similarities with aquatic reptile called Mosasaurus and false assumption that Apatosaurus was partially aquatic creature.
  • Apatosaurus had very small head (compared to the rest of the body), long, wide neck and 50-feet-long, whip-like tail. It had sturdy legs with a single claw on the front feet and three claws on the hind feet. Its front legs were slightly shorter than hind legs.
  • Due to large amount of swallowed food, Apatosaurus was producing huge amount of methane (greenhouse gas) each day. With approximately 520 million tons of methane produced each year, Apatosaurus and other herbivorous dinosaurs had significant effect on the global climate.
  • In 1997, two paleontologists published a research report stating the Apatosaurus tail would have resembled a bullwhip. They theorized an Apatosaurus could whip its tail and create a whip like cracking sound that could surpass 200 decibels. That is comparable to the decibels produced when a cannon is fired.
  • Shortly after discovery of Apatosaurus, archaeologists have found set of very large bones and officially named this "newly-discovered" species of dinosaur as "Brontosaurus". After thorough investigation of bones, it was discovered that Brontosaurus is actually adult Apatosaurus.
