A team of paleontologists discovered a new dinosaur species. This is a tyrannosaurine and a cousin of the famous Tyrannosaurus rex, which lived in the Late Cretaceous epoch. The researchers named it Daspletosaurus horneri and it is also known as Horner’s frightful lizard.
The newly discovered dinosaur species probably lived in what is now Montana some 75.2 million to 74.4 million years ago. They were part of a giant predatory dinosaurs group and related to tyrannosaurs. This species lived during the Late Cretaceous in both North America and Asia.
The Newly Discovered Dinosaur Species Had The Following Properties
A Daspletosaurus horneri must have had a body length of about 29.5 feet at a height of around 7.2 feet. It probably had a wide snout and small orbital horns. It may have also had slit-like pneumatic openings placed inside of its lacrimal bone.
It probably had a large horn behind its eye, which would have also been elevated beyond the respective side of its head. Research indicates that this featured a keratin covering.
The Daspletosaurus horneri probably preyed on ceratopsians or horned dinosaurs as well as hadrosaurs or crested duckbill dinosaurs. Also, it may have hunted pachycephalosaurs or dome-headed dinosaurs or theropods, or a smaller species of carnivorous dinosaurs.
A research team took a closer look at the new dinosaur species. They worked with well-preserved fossils, including the skeleton and skull of an adult specimen. Study results were released in a paper in the Scientific Reports journal.
“Daspletosaurus horneri was the youngest, and last, of its lineage that lived after its closest relative, Daspletosaurus torosus, which is found in Alberta, Canada.”
This is according to the study’s lead researcher, Dr. Thomas Carr from the Carthage College. By adding a new species to the tyrannosaur family tree, the researchers also gained new knowledge on their appearance and evolution.
