All rights reserved. Illinois-born Stephen Brusatte is one of the stars of modern paleontology. A former National Geographic grantee, he has discovered 10 new dinosaur species. He has also led groundbreaking scientific studies that have rewritten the history of these magnificent creatures which, thanks to Hollywood and countless children stories, haunt our imaginations today like never before. I think you could show a picture of T.
Pachycephalosaurus, genus of large and unusual dinosaurs found as fossils in deposits of North America dating to the Late Cretaceous Epoch (about the high, domelike skull formed by a thick mass of solid bone grown over the tiny brain.
The Field Museum fuels a journey of discovery across time to enable solutions for a brighter future rich in nature and culture. You may know SUE as the hilarious, pun-loving dinosaur turning Twitter into a personal smorgasbord. Or you might treasure that selfie you snapped with this fearsome fossil looming overhead. This specimen has been invaluable to the paleontological community since its discovery. And before settling into the luxurious life of a well-kept Chicago museum attraction, SUE had quite the history!
Dating back to the Cretaceous period—about 67 million years ago—this massive predator lived to the upper end of the life expectancy of a T. How do we know? Dinosaur bones have growth rings, just like trees.
Of the species that have been classified in the upper Morrison Formation of the western US, only three are universally recognized; S. The remains of over 80 individual animals of this genus have been found. Stegosaurus would have lived alongside dinosaurs such as Apatosaurus , Diplodocus , Brachiosaurus , Allosaurus , and Ceratosaurus ; the latter two may have preyed on it.
These were large, heavily built, herbivorous quadrupeds with rounded backs, short fore limbs, long hind limbs, and tails held high in the air. Due to their distinctive combination of broad, upright plates and tail tipped with spikes , Stegosaurus is one of the most recognizable kinds of dinosaurs.

New feathered raptor lived just before the asteroid strike
Bird skulls evolved much more slowly and are far less diverse than those of dinosaurs, a new study suggests. While the earliest birds evolved million years ago, in the Jurassic, previous studies suggest their modern diversity evolved in a burst of evolution after the other dinosaurs died out in the end -Cretaceous mass extinction. However, researchers say diversity is only the tip of the iceberg of broader variation in dinosaurs, the precursor to modern birds.
The team studied the structure of the bird and dinosaur skulls, using high resolution 3D scanning to explore how the bird skull fits into the big picture of dinosaur skull evolution. The skulls of more than species of birds and non-avian dinosaurs were 3D surface and CT scanned to create the biggest dataset of bird and dinosaur skulls to date.

A partial skull, painstakingly reconstructed from more than fragments has revealed that Homo erectus existed at least , years earlier than previously thought. In addition, the fossil remains, excavated from the Drimolen Fossil Hominin site in the Cradle of Humankind, northwest of Johannesburg South Africa , suggest that this hominin evolved in Africa and not in Asia.
The partial H. The skull pieces have been carefully reconstructed and superimposed on the outline of a Homo erectus skull. The sediments represent cave deposits but as the rocks that made up the caves have been eroded away, the breccias in which the fossils are located are exposed. The site is one of the most important in the world for early hominin remains, with more than a hundred individual fossil specimens described to date.

When paleontologist Mary Schweitzer found soft tissue in a Tyrannosaurus rex fossil , her discovery raised an obvious question — how the tissue could have survived so long? The bone was 68 million years old, and conventional wisdom about fossilization is that all soft tissue, from blood to brains , decomposes. Only hard parts, like bones and teeth, can become fossils. But for some people, the discovery raised a different question.
How do scientists know the bones are really 68 million years old? Today’s knowledge of fossil ages comes primarily from radiometric dating , also known as radioactive dating. Radiometric dating relies on the properties of isotopes. These are chemical elements, like carbon or uranium, that are identical except for one key feature — the number of neutrons in their nucleus. Atoms may have an equal number of protons and neutrons.
If, however, there are too many or too few neutrons, the atom is unstable, and it sheds particles until its nucleus reaches a stable state. Think of the nucleus as a pyramid of building blocks. If you try to add extra blocks to the sides pyramid, they may stay put for a while, but they’ll eventually fall away.
