When & Where

Gastonia’s fossils were first discovered in 1989 in Grand County, Utah by the fossil hunter, Robert Gaston. It was then named by James Kirkland in 1998 that was named after Gaston. The remains were retrieved in the same quarry where Utahraptor was found, causing paleontologists to assume that it was hunted by it. 

Size & Weight

Gastonia was about 15 to 20 feet (4.5 to 6 meters) long and around 5 feet tall. It approximately weighs around 1 ton or 1000 kg making it as heavy as Black Rhinoceros. 

Mobility & Diet

This dinosaur is a plant eater that uses its toothless beaks to crush soft plant materials. It is also known to be not aggressive and didn’t prey on other dinosaurs or animals. 

Interesting Points

  • Gastonia had a wicked tail where it had a row of triangular plates with sharp edges. 
  • Paleontologists are still studying if this dinosaur used to have butted heads, since one braincase discovered showed how great it is in absorbing shock and the skull was very thick. Unlike the other Ankylosaurian dinosaurs, Gastonia’s eyes were facing directly forward, which means they might stare at their opponents while knocking noggins.
  • Paleontologists were able to discover 3 different species of Gastonia
  • It is believed that this dinosaur is as long as a train car
  • Gastonia is said to be heavy as Black Rhinoceros
  • Its main predator is the Utahraptor
  • It had a toothless beak that’s used for crushing plant materials
  • Gastonia had a myriad of spikes that run down on its back and even had a tail spike that’s a good defense for its predators
