    Speckled dino spurs debate about ancient animals’ colors

    Structures found in fossil dinosaur skin may give clues to the creatures’ colors and how they lived. But not all scientists agree on how to interpret what they see.

  3. Fossils

    Dino brain found ‘pickled’ in boggy swamp

    Scientists claim to have identified the first fossil brain tissue from a dinosaur.

  4. Fossils

    Mini pterosaur from the age of flying giants

    Not all pterosaurs flying the Cretaceous skies had a wingspan as wide as a school bus is long. Some, new fossils show, were smaller than modern eagles.

  5. Fossils

    These may be the oldest fossils on Earth

    Some mini mounds in Greenland may just be the earliest evidence of life on Earth, deposited a mere 800,000 years after our planet first formed.

  6. Fossils

    Parasites wormed their way into dino’s gut

    Tiny burrows crisscross the stomach of a 77-million-year-old dinosaur fossil. These may be tracks left behind by slimy parasitic worms.

    Identifying ancient trees from their amber

    A Swedish teen’s analyses of a sample of amber may have uncovered a previously unknown type of ancient tree.

  8. Fossils

    Baby titanosaur was a mini version of its parents

    Fossils show that baby titanosaurs looked like mom and dad. They may have been active and independent from a young age.

    How to tell if a T. rex is expecting

    A chemical test of tyrannosaur bone can determine whether the dino was pregnant — and therefore a female.

    Neandertal toe contains human DNA

    DNA from a 50,000-year-old Neandertal woman’s toe bone shows humans left a mark on the ancient species — and much earlier than scientists had thought.
