Developing Saurolophus dino found at ‘Dragon’s Tomb’

Scientists describe a perinatal group of Saurolophus angustirostris, a giant hadrosaur dinosaur, all likely from the same nest, found at “Dragon’s Tomb” in Mongolia, according to a study published October 14, 2015 in the open-access journal PLOS ONE by Leonard Dewaele from Ghent University and the Royal Belgian Institute of Natural Sciences, Belgium and colleagues. […]

Fossilized eggshells reveal how warm blooded dinosaurs were

Scientists have used the fossilized eggshells of dinosaurs to estimate their body temperatures — and have revealed some surprises. Researchers have long debated whether dinosaurs were warm blooded like their living relatives, modern birds. In recent decades, the idea that dinosaurs — especially later, smaller, more bird-like dinosaurs – were warm blooded and active like birds, rather than more sluggish […]

Tropical ants in Europe

Tropical ants in Europe “Imagine I could send an ecologist to Europe back tens of millions of years ago. Then, ask them to look at the ants and to tell me where they think they have landed… They would say South East Asia,” explains Prof. Evan Economo of the Okinawa Institute of Science and Technology […]

125-million-year-old bird discovered

Birds have an enormously long evolutionary history: The earliest of them, the famed Archaeopteryx, lived 150 million years ago in what is today southern Germany. However, whether these early birds were capable of flying — and if so, how well — has remained shrouded in scientific controversy. A new discovery published in the journal Scientific […]

48-million-year-old uteroplacenta found

A 48 million year-old horse-like equoid fetus has been discovered at the Messel pit near Frankfurt, Germany according to a study published October 7, 2015 in the open-access journal PLOS ONE by Jens Lorenz Franzen from Senckenberg Research Institute Frankfurt, Germany, and Naturhistorisches Museum Basel, Switzerland, and colleagues. The authors of this study completed their […]

molecular analysis clarifying dino color claims

The color of dinosaurs is a fascinating topic, and in recent years the discovery of melanosomes — small, pigment-filled sacs — associated with fossilized dinosaur feathers has given rise to all sorts of speculation about our prehistoric pals, from the hue of their plumage to color’s impact on behavior. It all sounds wonderful — but […]

Mammoth fossil unearthed

While digging in his field on Monday, Michigan farmer James Bristle found what he thought was ordinary debris in his field. After digging further, he discovered that what he had found wasn’t a fence post, but bones from a Woolly Mammoth. After the discovery, Bristle contacted the University of Michigan, who arrived to excavate the […]

Odaraia alata: 500 Million Old

A 500-million-year-old fossilized arthropod found in the Burgess Shale, a fossil field in the Canadian Rockies, may provide clues to how heads evolved in early animals. The fossil is a submarine-shaped arthropod, Odaraia alata, of the Middle Cambrian Period. A paper in Current Biology reports that both Odaraia alata, originally found about 100 years ago, […]

More oxygen in the core of Earth

There is more oxygen in the core of Earth than originally thought. Lawrence Livermore geologist Rick Ryerson and international colleagues discovered some new findings about Earth’s core and mantle by considering their geophysical and geochemical signatures together. This research provides insight into the origins of Earth’s formation. Based on the higher oxygen concentration of the […]

Marrellomorph redefine evolutionary timelines

Some of the oldest marine animals on the planet, including armoured worm-like forms and giant, lobster like sea creatures, survived millions of years longer than previously thought, according to a spectacularly preserved fossil formation from southeastern Morocco. The Lower Fezouata formation has been revealing exciting discoveries about life in the Ordovician — around 485 — […]
