Tyrannosaurus rex XXL - Fossil skeleton - 45 cm (No reserve price)

A highly detailed replica of a Tyrannosaurus rex skeleton. Class: Carnivore Fossil dimensions: length 45 cm. Height 17 cm. Sue Hendrickson, an amateur paleontologist, discovered the largest and most complete Tyrannosaurus skeleton (about 85%) in the Hell Creek Formation on August 12, 1990. It includes the base and the stand. SHIPPING GUARANTEE: Well packaged and insured, with tracking Tyranno (named), fierce and relentless like all top predators on the food chain. And even very intelligent. A study changes the image that novels and films have often given of Tyrannosaurus rex, which 65 million years ago had no rivals among carnivores. Now some researchers say that the T-rex’s cerebral cortex had a neuron density comparable to that of a baboon, and this would have allowed it to live up to 40 years, learn to use tools, and pass on its knowledge to its offspring. This is stated by a controversial study by neuroscientist Suzana Herculano-Houzel of Vanderbilt University (USA), who reached this estimate by evaluating the brains of modern birds (dinosaur descendants) and relating them to the skull size of the tyrannosaur.
