Scientists who have been studying the fossil of a previously unknown species of horned dinosaur in northwest New Mexico have discovered a new species that they believe is a primitive ancestor of the Triceratops and its kin. The scientists believe the fossils are from the late Cretaceous period, about 66 million years ago, and that the new species has 3 large spikes on its head and a bony frill that protected its neck. The discovery of the new species has been published in the journal Nature. The new species is called Triceratops horridus, and it was discovered by a team of paleontologists. Bisticeratops froeseorum, a new species of horned dinosaur, has been discovered in New Mexico.

A brief history of dinosaurs
Dinosaurs were a successful group of animals that appeared between 240 million and 230 million years ago and came to govern the globe until around 66 million years ago, when a massive asteroid collided with Earth. Dinosaurs grew from a group of largely dog- and horse-sized species to the most massive beasts that ever existed on land during this time period. Dinosaurs were the dominating species on Earth for almost 150 million years, causing the extinction of countless other species.
During this time, they grew from a small group of species into an enormous array of species with a varied range of body sizes and shapes. Dinosaurs spread across every continent on Earth, with the exception of Antarctica, and inhabited many different environments. Dinosaurs were the rulers of the Earth, and no animal was able to compete with them. Dinosaurs came to be at the top of the food chain.
They were active during the day and night, and they were able to see in color, which allowed them to see better than any other living animal. Many different types of dinosaurs evolved, each one with its own unique set of adaptations. Dinosaurs were able to run faster than any other animal, and they were able to use. Dinosaurs were able to use their teeth to crush their food. Dinosaurs were able to climb trees and use their tails to pull themselves up.

The discovery of the new species of dinosaur
The specimen was discovered in the Upper Cretaceous strata of New Mexico’s San Juan Basin in 1975. When researchers discovered bone jutting out of the earth, it was linked to a virtually intact cranium. After decades of cleaning and examination at the New Mexico Museum of Natural History, the skull was identified as belonging to a previously undiscovered species. In fact, the specimen became the centerpiece of the museum’s permanent collection.
“Further analysis into specimens that exist in museum collections, along with fresh specimen collecting and research, will help us to better understand these dinosaurs to an even greater degree,” said Dr. Steven Jasinski, a professor at Harrisburg University of Science and Technology, in a statement.
Tyrannosaurus rex and other tyrannosaurids mostly preyed on the gentle giants, according to a hypothesis supported by evidence found on the Bisticeratops’ skull. Several bite marks were found on different regions of the head, including the upper jaws, cheek, and frill, and are likely to have been produced by a tyrannosaurid due to their placement and size. The Bisticeratops was a large herbivore.
How the finding of this new dinosaur has changed paleontology
“While just the skull of Bisticeratops was found,” Jasinski said in a news, “this fossil provides us a lot of information about horned dinosaurs in a period and location that was unique. “While other ceratopsids are known from older strata in this region, Bisticeratops may show us the next step in the evolution of these horned dinosaurs in this region and fills in a gap leading to the last ceratopsid dinosaurs in this region before their extinction at the end-Cretaceous mass extinction,” the researchers write.
What is a horned dinosaur?
Paleontologists have discovered a new dinosaur in the southwest United States. Crittendenceratops krzyzanowskii is a new ceratopsid (horned) dinosaur, approximately six feet in length, discovered in southern Arizona rocks 73 million years old (Late Cretaceous). It is one of Arizona’s few dinosaur names, and it is significant because it helps fill in the gap in our knowledge of ceratopsid evolution.
What dinosaurs lived in New Mexico?
New Mexico had a generally arid environment during the Jurassic period, and it was home to many dinosaurs, including Allosaurus, Stegosaurus, and the massive long-necked sauropods. During the Cretaceous period, seawater blanketed eastern New Mexico, while dinosaurs, especially tyrannosaurs, dominated on land. The Cretaceous period ended with the extinction of the dinosaurs, and the end-Cretaceous period began with the extinction of the tyrannosaurs
