What is *Labocania aguillonae*, and when did it live?
The newly discovered species, *Labocania aguillonae*, is a tyrannosaur that lived in what is now Coahuila, Mexico, approximately 72.5 million years ago during the Campanian age of the Cretaceous period.
Where was the research on *Labocania aguillonae* published, and which institutions were involved?
The research on *Labocania aguillonae* was published in September in the journal MDPI Fossil Studies and involved a team of researchers from the Museo del Desierto and the University of Bath.
What does the discovery of *Labocania aguillonae* suggest about tyrannosaur diversity in North America?
The discovery of *Labocania aguillonae* suggests a greater diversity of tyrannosaur species in the southern part of North America than previously understood, contrasting with the species known from more northern regions like Canada and the United States.
Where were the fossils of *Labocania aguillonae* found, and how long were they in storage before being studied?
The fossils of *Labocania aguillonae* were initially discovered in 2000 but remained in storage at the Museo del Desierto in Saltillo, Mexico for over two decades before being identified as a new species.
What are some physical characteristics of *Labocania aguillonae*, and how do they differ from the *Tyrannosaurus rex*?
*Labocania aguillonae* was a relatively lightly built tyrannosaur, possessing long legs suggesting speed and large eyes, potentially for hunting in low-light conditions. Unlike the *Tyrannosaurus rex*, its skull was shorter and broader.
