Billion Year Old Seawater

As it was, and as it is, an ocean on Earth (T. Fioreze)

If there is one thing our universe makes a lot of, it is water. This isn’t an immediately obvious property based solely on the universal inventory of stuff. Hydrogen utterly dominates normal matter throughout the cosmos, and despite some 13 billion years of stellar nuclear fusion only a small number of these primordial protons have [...]

Molecular Analysis Supports Controversial Claim for Dinosaur Cells

RALEIGH—Twenty years ago, paleontologist Mary Schweitzer made an astonishing discovery. Peering through a microscope at a slice of dinosaur bone, she spotted what looked for all the world like red blood cells. It seemed utterly impossible—organic remains were not supposed to survive the fossilization process—but test after test indicated that the spherical structures were indeed [...]

Complex Brains Existed 520 Million Years Ago in Cockroach Relative

insect brain evolution 520 million years arthropod fossil

Your everyday cockroach might not seem terribly intelligent. But new fossil evidence from 520 million years ago suggests that this insidious insect might have had some surprisingly smart early ancestors. Cockroaches and other insects belong to a group called the arthropods, which arose some 540 million years ago. A new Chinese fossil is yielding new [...]

Odd Insect Fossils Suggest Early Carnivorous Lifestyle

insect fossil new order

A recently described swarm of fossil insects unearthed from a 100 million-year-old South American formation are a Frankensteinian riot of mismatched parts: lengthy praying mantis-like front legs; long, slim wings like a dragonfly; and wing-vein patterns to match those of modern-day mayflies. So unusual is their form that scientists are cataloguing the creatures into a [...]

30 years After Televised Spat, Rival Anthropologists Agree to Bury the Hand-Ax

Paleoanthropology is a discipline known as much for its feuds as for its findings. Among the best known of these clashes is a longstanding one between two of the field’s most famous scientists, Donald Johanson and Richard Leakey. Both have led expeditions that made such extraordinary fossil discoveries as the 3.2-million-year old "Lucy" skeleton from [...]

New fossil shows “Lucy” to have been steady on her feet

lucy human ancestor foot bone modern walking

At some point in the past five million years or so, our human ancestors traded in an arboreal existence for a dedicated two-legged life on the ground. A patchy fossil record, however, has frustrated researchers hoping to pinpoint the emergence of more modern human upright walking.  Even the gait of the well-studied "Lucy" species, Australopithecus [...]

A whale of a fossil is named in honor of Herman Melville

new fossil of giant sperm whale named for Herman Melville attacking a baleen whale

The large leviathan that was the bane of Ahab’s existence in Herman Melville’s Moby Dick has a new ancient relative that might have lived up to the fictional beast’s monstrosity. Leviathan melvillei, a giant toothed whale, is described in a new paper, published online June 29 in Nature (Scientific American is part of Nature Publishing [...]

Secrets of a Paleoart Rockstar: Julius Csotonyi

Sinocalliopteryx_Csotonyi-m

One of the most popular fields of science with children and adults alike is paleontology. And there’s a very good reason for this. Since the first fossil was recognized and found, it inspired imaginations to envision what the animal was like when it was alive. From the myths of giant cyclops to sinewy dragons, fossils [...]

The great Symbolist draughtsman Max Klinger created this image as one of ten in a narrative series of etchings called, Paraphrase on the Discovery of a Glove, which follows the dreamy travels of a single lost glove. This second-last panel, The Seizure is remarkable in a couple of ways. Symbolists, like their artistic descendants the [...]
