Fun Facts about Meraxes

A huge theropod skeleton was discovered in an approximately 94-million-year-old rock stratum of Argentina’s Huincul Formation in 2012. A team of experts began excavating the remains in 2014. Juan I Canale, Sebastián Apestegua, Pablo A. Gallina, Jonathan Mitchell, Nathan D. Smith, Thomas M. Cullen, Akiko Shinya, Alejandro Haluza, Federico A. Gianechini, and Peter J. Makovicky described the type species Meraxes gigas in 2022.

The fossil is made up of an incomplete skeleton and skull components. The dinosaur was roughly 50 years old when it died, which is very elderly for a primitive theropod. Meraxes’ skull had crests, furrows, lumps, and little horns, according to scientists. The meraxes’ body is eerily similar to that of tyrannosaurs. The skeleton is one of the most complete carcharodontosaur skeletons discovered in the southern hemisphere, according to palaeontologists.

Meraxes was a member of the theropod family Carcharodontosauridae, which also included other titanic dinosaurs such as Giganotosaurus, Mapusaurus, and Carcharodontosaurus. Researchers estimate that Meraxes gigas measured 11 metres in length and weighed approximately 4 tonnes.

The species featured a skull ornamented with crests, bumps, and small horns, and the individual that was unearthed looks to have perished at approximately 50 years of age, which is roughly double the average lifespan of Tyrannosaurus rex. M. gigas roamed the Earth during the Late Cretaceous Epoch, around 20 million years before T. rex, and the dinosaurs are quite distantly related on the evolutionary tree.
