Lokiceratops rangiformis made its home in parts of what's now northern Montana and is thought to have the largest frill horns ever seen among its kind to date. A reconstruction of Lokiceratops surprised by a crocodilian in the 78-million-year-old swamps of northern Montana, USA.

Researchers have unearthed a new armored dinosaur in Utah, a new species of ankylosaur, known as Akainacephalus johnsoni. The catch? It lived on the lost continent known as Laramidia. A. johnsoni, a member of the ankylosaurid family, lived 76 million years ago in what is now southern Utah, but was once a land mass known as Laramidia, an island continent that split North America in two. Eventually, the sea shrank and the two parts combined to form what is now known as North America. ..." Measuring between 13 and 16 feet in length and 3.5 feet tall, Akainacephalus jonhnsoni is...

The Tyrannosaurus rex may be among the most well-known and terrifying dinosaurs to walk the Earth, but a newly discovered relative may have been even scarier. Dynamoterror dynastes, a variant of T. rex, was discovered in New Mexico in 2012 by a team of researchers, led by  Western Science Center paleontologist Andrew McDonald. It has a slightly different bone structure compared to its successor cousin. "Despite fragmentation of much of the axial and appendicular skeleton prior to discovery, the frontals, a metacarpal, and two pedal phalanges are well-preserved," the study's abstract reads. "The frontals exhibit an unambiguous autapomorphy and a second potential...
