It pays to dig deeply into museum collections, as this release from Ludwig-Maximilians University proves: A long forgotten fossil skull in the collections of the Natural History Museum in London has now provided crucial clues to the early stages of ...

The skull of Proceratosaurus, a relative of T. rex that lived about 170 million years ago, was tipped with a nose horn. Researchers have not determined the function of that horn.

Spanning just 10 feet in length and sporting a tiny horn on its nose, a newly identified dinosaur has been identified as the oldest known relative of the fierce meat-eater Tyrannosaurus rex.

One of the Tyrannosaurus rex's direct ancestors was little more than a pint-sized reptile, according to an international team of researchers. A recently rediscovered dinosaur skull shows part of the T. rex's evolution.

Tyrannosaurus rex and its relatives were North America's dominant predators in the late Cretaceous period, about 99 million to 65 million years ago, but a new analysis of a toothy fossil skull suggests that the early history of this group includes smaller meat-eating ancestors that date as far back as 170 million years ago.

Washington, November 5 : With the help of an ultramodern imaging technique, a team of scientists has recognized a long forgotten fossil skull in the collections of the Natural History Museum in London, as belonging to the oldest known relative of the Tyrannosauridae.

Spanning just 10 feet in length and sporting a tiny horn on its nose, a newly identified dinosaur has become the oldest known relative of the fierce meat-eater, Tyrannosaurus rex. The discovery suggests such tyrannosaurs were quite petite before they evolved into giant killing machines just before their demise.

Scientists have uncovered new clues about the early stages of the Tyrannosaurus rex’s beginnings. A team of British and German researchers studied a fossil held at London’s Natural History Museum.

( Ludwig-Maximilians-Universität München ) A long forgotten fossil skull in the collections of the Natural History Museum in London has now provided crucial clues to the early stages of the lengthy evolutionary history of Tyrannosaurus rex and related large carnivorous dinosaurs.

(PhysOrg.com) -- Remains of the oldest-known relative of T.rex have been identified, more than 100 years after being pulled out of a Gloucestershire reservoir, according to research published in the Zoological Journal of the Linnean Society today.
