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 — […]

fossils formation unlocked

Fossils tell amazing stories and inspire them, too — just think of this summer’s “Jurassic World” blockbuster. But because some of the processes that preserve fossils are not well understood, there’s still more information that they could reveal. Now scientists report in ACS’ journal Analytical Chemistry a new way to probe fossils to find out […]

Bunostegos akokanensis: A Pre reptile

A newly published analysis of the bones of Bunostegos akokanensis, a 260-million-year-old pre-reptile, finds that it likely stood upright on all-fours, like a cow or a hippo, making it the earliest known creature to do so. To date all of the known pareiasaurs who roved the supercontinent of Pangea in the Permian era a quarter […]

Coelacanths :Living Fossils

The coelacanth, an elusive deep-sea dweller long thought extinct, had another item added Tuesday to an already-long list of unusual physical traits: an obsolete lung lurking in its abdomen.Similar to the human appendix, the organ was likely rendered defunct by evolution, researchers noted in the journal Nature Communications.Like all fish, today’s coelacanths — referred to […]

‘Lightning Claw’ Dinosaur Fossil

The remains of a “lightning claw” dinosaur was discovered by opal miners in Lightning Ridge, New South Wales. The giant dinosaur was said to have existed during the mid-Cretaceous period in the supercontinent called Gondwana, according to Australian Geographic.  The dinosaur belonged to the megaraptorid group of dinosaurs known primarily in Argentina. It is believed […]

Ariyalur Fossils : Belemnites

Belemnites (Belemnitida) were squid-like animals belonging to the cephalopod class of the mollusc phylum, and therefore related to the ammonites of old as well as to the modern squids, octopuses and nautiluses. Now extinct, their fossils are found in rocks of Jurassic and Cretaceous ages, with a few species hanging on into the early part […]
