The characteristics developing independently in unrelated groups of dinosaurs provides support for that hypothesis, the scientists wrote. Witton) Tyrannosaurus rex might not have been puckering up for a good ol' snog, but the dinosaur 's teeth were not exposed like a 'gator's instead, they protected behind a pair of lizardy lips. The researchers also argued that the small size of the arms could be directly related to their massive skulls, as the evolutionary process counterbalances one with the other. rex, lips and all, swallowing a hapless juvenile Edmontosaurus. Canale believed that Meraxes might have used their arms to set themselves straight after falling down or to hold a partner during mating. Juan Ignacio Canale, one of the Argentine researchers who found the fossils, told New Scientist that “those proportionally tiny arms had some sort of function.” Canale said that researchers found that Meraxes’ arm muscles were well developed, suggesting they were used. Scientists have various ideas as to why this happened. But the discovery of the similar characteristics in an unrelated species millions of years apart shows that both creatures evolved independently to embody the same physical trait. Previously, predators of that size with large heads, long legs, and small arms had mostly been attributed to the same group as the Tyrannosaurus. rex, the researchers contend that it comes from a different group of dinosaurs called the Carcharodontosauridae which lived around 20 million years before, during the Early Cretaceous period. Two years ago, a triceratops skeleton that the Guinness World Records declared as the world's biggest, known as "Big John," was sold for 6.6 million euros ($7.2 million) to a private collector at a Paris auction.Although Meraxes looks similar to a T. rex skeletons that were auctioned off, according to Koller: Chicago's Field Museum of Natural History bought "Sue" for $8.4 million over a quarter-century ago, and "Stan" sold for nearly $32 million three years ago. The two areas the bones for Trinity came from were also the source of other T. A picture of "Trinity" is seen during sale of the skeleton of the Tyrannosaurus-Rex (T-Rex) by Koller auction house in Zurich, on April 18, 2023. Hollywood movies such as the blockbuster "Jurassic Park" franchise have added to the public fascination with the carnivorous creature.

"But here we have truly original Tyrannosaurus skull bones that all originate from the same specimen." Created using popular Dinosaur Name Tyrranosaurus Rex is the king of dinosaurs. In fact, most dinosaurs are found without their skulls," Nils Knoetschke, a scientific adviser who was quoted in the auction catalog. "When dinosaurs died in the Jurassic or Cretaceous periods, they often lost their heads during deposition (of the remains into rocks). Witton) Tyrannosaurus rex might not have been puckering up for a good ol snog, but the dinosaur s teeth were not exposed like a gators instead, they protected behind a pair of lizardy lips. The auction house said the skull was particularly rare and also remarkably well-preserved. rex, lips and all, swallowing a hapless juvenile Edmontosaurus. Koller said "original bone material" comprises more than half of the restored fossil. rex display heats up debate over auctions of dinosaur skeletons: "Harmful to science" rex's ferocious image may have just taken a hit rex, dubbed "Trinity," was built from specimens retrieved from three sites in the Hell Creek and Lance Creek formations of Montana and Wyoming between 20. The skeleton of a Tyrannosaurus rex is seen in the Dinosaur Gallery of the Royal Belgium Institute of Natural Sciences on Apin Brussels, Belgium. Green did not identify the buyer, but said it was a "European private collector." Including the "buyer's premium" and fees, the sale came to 5.5 million Swiss francs (about $6.1 million), Koller said. Dinosaur skin is rarely preserved, and what we get is usually patchy and incomplete. rex, are incomplete, consisting primarily of bones. The Tyrannosaurus Rex is a Theropod apart of the Tyrannosauridae. I hope it's going to be shown somewhere in public." Witton) Most of the dinosaur fossils we've retrieved, including the theropod group that includes T. Tyrannosaurus Rex, also referred to as trex or rex, is a Large, Carnivorous Dinosaur.
