Ankylosaurids are a family of steel-skinned herbivorous dinosaurs that lived during the Cretaceous period, between 100 and 66 million years ago. After being studied for 10 years, experts believe that the dinosaurs they found in Utah were the latest in their kind.
By experts, this dinosaur was named Akainacephalus johnsoni and is believed to be 76 million years old. The name was taken from Greek which is a combination of two words.

"Akaina" which means thorn and "cephalus" which means head. When combined, the meaning is the same as a thorny head. Giant Fossils First Answer Most ankylosaurs found in North America have fine bones as head protectors.
This is what convinced experts that the fossil they found in Utah was a new type of ankylosaurus. Unlike North American ankylosaurus, the research team revealed A. johnsoni was more like ankylosaurus from Asia, such as Saichania and Tarchia.
"The most sensible hypothesis is that ankylosaurus from Utah has relatives elsewhere, and we were very surprised to find that A. johnsoni was closely related to Asian dinosaurs," Randall Irmis from the Natural History Museum of Utah, told Science Alert on Friday (20 / 7/2018).

In a report published in the journal PeerJ on Thursday (07/19/2018), researchers suspect there was a migration of dinosaurs from Asia to America in the late Cretaceous period. When the sea level recedes, A. johnsoni and a close relative of Nodocephalosaurus travel the land and arrive in America.
"This (actually) is not the first ankylosaurus of the Cretaceous period found in Utah. Thanks to the findings of this special creature, the evidence of the northern and southern regions of Laramidia used during the Campanian period was getting stronger, "said the lead author of this study, Jelle Wiersma.

This is what the expert says. The finding of the A. johnsoni skeleton is the most complete of the late Cretaceous periods in the area. These findings include a complete skull, a number of vertebral bones, a complete tail and also several front and back legs. "This is very interesting and important for the science of paleontology that we can read so much information from the fossil record, allowing us to better understand extinct organisms and parts of their ecosystem," Wiersma explained.
