Earth turned faster at the end of the time of the dinosaurs than it does today, rotating 372 times a year, compared to the current 365, according to a new study of fossil mollusk shells from the late Cretaceous. This means a day lasted only 23 and a half hours, according to the new study in AGU's journal Paleoceanography and Paleoclimatology.

Virginia Tech paleontologists have made a remarkable discovery in China: 1 billion-year-old micro-fossils of green seaweeds that could be related to the ancestor of the earliest land plants and trees that first developed 450 million years ago.

The eyes of the extinct sea scorpion Jaekelopterus rhenaniae have the same structure as the eyes of modern horseshoe crabs (Limulidae). The compound eyes of the giant predator exhibited lens cylinders and concentrically organized sensory cells enclosing the end of a highly specialized cell.

The search for evidence of life on Mars could be helped by fresh insights into ancient rocks on Earth. Research which suggests that structures previously thought to be fossils may, in fact, be mineral deposits could save future Mars missions valuable time and resources.

Stromatolites are complex microbial mats that form lithified layers and ancient forms are the oldest evidence of life on earth, dating back over 3.4 billion years. Their emergence aligns with the oxygenation of the Earth's atmosphere and insight into these ancient structures would shed light on the earliest days of Earth.

Though our understanding of the anatomy of the earliest animals is growing ever more precise, we know next to nothing about their behaviour.

A clutch of marine fossil specimens unearthed in northern Portugal that lived between 470 and 459 million years ago is filling a gap in understanding evolution during the Middle Ordovician period.

Newly discovered fossilized tracks suggest multicellular life could be 1.5 billion years older than previously thought, according to a new study by an international team of researchers including scientists at the University of Alberta.

All over the world, spectacular fossils have frequently been found preserved inside solid, roughly spherical rocks called "concretions."

Take a good look at these photos: They show you 1.6 billion years old fossilized oxygen bubbles, created by tiny microbes in what was once a shallow sea somewhere on young Earth.
