A T. rex tooth crown was once found embedded in the backbone of a hadrosaurid, or duck-billed dinosaur. Because this dental fragment is surrounded by re-healed bone material, we know the herbivore was alive when the tooth's owner attacked it. Moreover, it survived the encounter. Frequently...

Tyrannosaurus rexhas always been recognized as fearsome—theNew York Timeslabeled it the “prize fighter of antiquity” when the first mountedT. rexbones were displayed in 1906—but thanks to two British researchers, it’s now clear that the giant carnivore bit harder than experts had thought. ...

To put that into perspective, there have only been around 50 major specimens of the Tyrannosaurus found, with only a few being a complete fossil of the dinosaur. It’s no small wonder the Tyrannosaurus Rex was such a good hunter.
T. rexwas constantly losing and growing new teeth, so it's not uncommon to find the tyrant's teeth at fossil sites in western North America. According to a2017 paper, theT. rexSue had a bite force of up to 34,520 newtons. When looking at the pressure exerted by a single tooth, the...
I saw a Juvenile Tyrannosaurus rex tooth (or Nanotyrannus) with really good price.. Seller told that this is from Hell Creek formation, Garfield County, Montana. I can't find any oddity or fabrication... but I want to hear everyone's opinion since the price is too good to be true. ...
T-RexBite Force T rexis estimated to have had the strongest bite force of any land animal, living or extinct. One study (source) found that a singleT rextooth positioned at the back of the jaw could exert a bite force of 35,000 to 57,000 Newtons... that’s over twice the bite for...
Barnum excavating the first T-Rex Data pertaining toT. rexhas grown exponentially over the last 35 years, but the fruits of scientific inquiry in this field will always be limited by exceedingly low rates of fossil preservation. According to Charles Marshall, director of the University of Californ...
you might be making the logical leap that this fossil find is then linked to the hotbed of furious controversy that still leaves palaeontology in crisis almost 100 years after Lambe suggested it for the tyrannosaurGorgosaurus. If the hadrosaur survived an attack from aT. rex, thenT. rexwas a...
