Tyrannosaurus rex Skull on Display at BYU Museum of Paleontology

A cast of #Tyrannosaurus rex AMNH 5027, “Dali,” on display at the Brigham Young University Museum of Paleontology in Provo, Utah. #Trex has a big mouth, one that is all the larger standing next to it! In this room is a #Carcharodontosaurus composite skull and though the latter is longer, it is far more gracile. The #tyrannosaur is chunky and robust. Both are giant, the Carch would invoke as much fear as the T. rex to its lunch. Seeing them so close, one can see how they pursued different prey with different styles of bite. If #Tyrannosaurus ate like herons and cormorants, how heavy of an animal could it flip into the air and consume in one gulp? A 200 lb biped? I dub this skull Dali because it reminds me of my favorite Salvador Dali painting, Persistence of Memory, the one with the melting clock. 5027, though, needs no nickname. I’d suggest that number is retired by the ICZN :-). If you look at the other side of this T. rex skull you will see it is very different in shape (thus Dali) thanks to postmortem deformation that happened sometime in the last 66 million years :-). Deformation is one of the banes of paleo, happily we get to see a non-crushed side, too. This Late #Cretaceous #dinosaur is the most famous of all #dinosaurs, and deservedly so. It encapsulates everything the general public loves: size, power, savagery, ferociousness. With huge teeth and a giant skull with the ability to bite through seemingly any prey, instant love! It has #heterodont dentition, the premaxillary teeth being quite different in morphology from the rest of the teeth, those “killer bananas” or “railroad spikes” for which it is recognized. Why I know not. The holes in the jaw are for nerve endings and blood vessels. Did it have lips? Check out our YouTube page for videos on that very topic. I am staying out of this one, other than to say the lip study uses research that includes exactly 1 #tyrannosaurid tooth. I’d feel vastly more comfortable if they had used a few teeth, one from a rex would have been great, as all other #theropods replace their teeth very fast. Seems easy enough for someone to test, there is a paper waiting m there :-). #FossilCrates
