It is a sister species to the famous Tyrannosaurus rex.
Newly discovered Tyrannosaur species
Tyrannosaurus mcraeensis lived between 71 and 73 million years ago in New Mexico, USA.
A new species of giant tyrannosaur has been discovered in New Mexico, USA. The dinosaur, named Tyrannosaurus mcraeensis, lived between 71 and 73 million years ago and is a sister species to the famous Tyrannosaurus rex. While both dinosaurs were large predators, they had subtle differences in their skull bones that allowed scientists to distinguish them from each other. The discovery of this new species sheds light on the evolutionary history of tyrannosaurs and suggests that they may have originated in North America before spreading to Asia.
Tyrannosaurus mcraeensis is a newly discovered subspecies of tyrannosaur that is older and more primitive than its better-known cousin, but just as large.
The study identifies Tyrannosaurus mcraeensis in New Mexico which shows that Tyrannosaurus was in North America millions of years before paleontologists previously thought.
Towards the very end of the Cretaceous Period, giant horned dinosaurs created a food source that could support giant tyrannosaur spread north.
Dinosaurs may have evolved to larger sizes in the south due to reasons unknown.

The article contains a statement that Tyrannosaurus rex first arrived in North America around 66 million years ago. However, the discovery of Tyrannosaurus mcraeensis suggests that it was actually present on the continent millions of years before this.
]Tyrannosaurus likely originated in southern North America then later expanded into much of the western portion of the continent.
Tyrannosaurus mcraeensis was discovered in New Mexico which shows that Tyrannosaurus was in North America millions of years before paleontologists previously thought.
The differences between Tyrannosaurus mcraeensis and other tyrannosaurs are subtle due to evolution slowly causing mutations to build up over millions of years.
T. rex suddenly appeared in North America around 66 million years ago, but with no close relatives in North America, how it arrived and evolved on the continent remains a mystery.
Accuracy
Tyrannosaurus mcraeensis had a more slender jaw than what is normally seen in a T. rex
Unlike T. rex, Tyrannosaurus mcraeensis didn't have a prominent ridge over its eyes.
Deception
(30%)
The article is deceptive in several ways. Firstly, the author claims that Tyrannosaurus mcraeensis was discovered decades before it officially got its scientific name. However, this statement contradicts the fact that no one knew what species of dinosaur they were dealing with until 2013 when Sebastian G. Dalman suggested it might be something different.

Fallacies
(85%)
The article contains an informal fallacy called 'appeals to authority'. The author claims that the robust jaw of T. rex meant it could do whatever it wanted and had less bite force than Tyrannosaurus mcraeensis. This is not supported by scientific evidence, as there are no studies or experiments mentioned in the article to back up this claim.
The lower jaw in a Tyrannosaurus rex is actually quite robust.
Bias
(85%)
The article contains a statement that Tyrannosaurus mcraeensis was originally categorized as T. rex due to the size of its specimens. However, this is not entirely accurate as there were two big differences between T. rex and T. mcraeensis: The lower jaw in a Tyrannosaurus rex is actually quite robust while our jaw was obviously big and toothy but slender than what we normally see in a Tyrannosaurus rex, which means that it would have less bite force. Additionally, unlike T. rex, T. mcraeensis didn't have a prominent ridge over its eyes.

The author has a conflict of interest on the topic of Tyrannosaurus rex as they are reporting for New Mexico Museum of Natural History & Science which is involved in paleontology research and has an exhibit related to T. rex.
A new study has identified a previously misclassified dinosaur skull as belonging to a new species called Tyrannosaurus mcraeensis
`T. mcraeensis` is a cousin of the well-known `T. rexa and may have been even larger in size
Tyrannosaurus mcraeensis dates back to between 71 and 73 million years ago, making it up to 7 million years older than `T. rexa
The skull of `T. mcraeensisa has distinct differences in structure compared to that of j T. rex
Until now, many fossils within the tyrannosaur lineage have been discovered in modern-day Mongolia and China, but this discovery suggests that tyrannosaurs actually originated in North America and later spread to Asia
Tyrannosaurus mcraeensis is likely to have rivaled j T. rexa in size with the possibility of even larger specimens existing

Deception
(50%)
The article is deceptive in several ways. Firstly, the title of the article claims that a skull found in New Mexico is a cousin of T. rex and even bigger than it was previously thought to be. However, this claim turns out to be false as the study reveals that this newfound predator species belongs to a different species altogether and rivals T. rex in size.
The title of the article claims that a skull found in New Mexico is a cousin of T. rex and even bigger than it was previously thought to be.
Fallacies
(85%)
The article contains an appeal to authority fallacy by citing the American Museum of Natural History as a source for information about T. rex's size. The author also uses inflammatory rhetoric when describing Tyrannosaurus mcraeensis as 'even larger than the previously-crowned apex predator'. Additionally, there is an example of a dichotomous depiction in the sentence 'T. rex may not be the king of dinosaurs after all.' The author presents two options: T. rex being the king or it not being so.
The American Museum of Natural History claims that T. rex was 12 feet tall and 40 feet long.
Bias
(85%)
The article reports that a skull found in New Mexico is not T. rex but rather a different species of predator called Tyrannosaurus mcraeensis. The author uses quotes from experts to support their claim and provides evidence such as the age of the fossil and differences in its structure compared to T. rex.
Tyrannosaurus mcraeensis rivaled T. rex in size.

Tyrannosaurus mcraeensis lived between 71 and 73 million years ago, or between 5 and 7 million years before T. rex.
The newly-identified species has multiple subtle differences in the shape of, and joins between, the skull bones compared to T. rex.
Accuracy
The differences between Tyrannosaurus mcraeensis and other tyrannosaurs are subtle due to evolution slowly causing mutations to build up over millions of years.
Deception
(50%)
The article is deceptive in several ways. Firstly, the author claims that Tyrannosaurus mcraeensis was a sister species of Tyrannosaurus rex when it is not clear if they are related or not. Secondly, the author states that tyrannosaurid dinosaurs originated on Laramidia but does not provide any evidence to support this claim. Thirdly, the author claims that Tyrannosaurus mcraeensis lived between 71 and 73 million years ago when it is actually estimated to have lived around 5-7 million years before T. rex.
The article states that 'Tyrannosaurid dinosaurs originated on Laramidia' but does not provide any evidence to support this claim.
Fallacies
(75%)
The article contains several fallacies. The author uses an appeal to authority by citing Dr. Sebastian Dalman from the New Mexico Museum of Natural History and Science as a source for information about Tyrannosaurus mcraeensis. However, this does not necessarily mean that his statements are accurate or reliable.
The discovery of Tyrannosaurus mcraeensis suggests that tyrannosaurid dinosaurs originated on Laramidia.
Bias
(85%)
The article contains a few examples of religious bias. The author mentions that tyrannosaurid dinosaurs were the dominant predators in North America and Asia during the Late Cretaceous epoch, which implies that they had some sort of divine or supernatural power over these regions. Additionally, the authors suggest that Tyrannosaurus mcraeensis may have originated in southern Laramidia, an island continent that existed between 100 and 66 million years ago and stretched from modern-day Alaska to Mexico. This implies a religious or spiritual connection to this region.
