The first vertebrates to walk the Earth emerged from the sea almost 20 million years earlier than previously thought, say scientists who have discovered footprints from an 8-foot-long (2.4-meter-long) prehistoric creature.
Dozens of the 395-million-year-old fossil footprints were recently discovered on a former marine tidal flat or lagoon in southeastern Poland.

Just like modern-day starlings, some ancient birds had glossy black feathers with a metallic, glimmering sheen, scientists report in a new study.
The discovery is based on 40-million-year-old fossils of an unidentified bird species that were stored at the Senckenburg Museum in Frankfurt, Germany for up to 30 years. The fossils represent the first evidence of ancient iridescence in feathers.

An ancient fossil crocodile coated in armadillo-like body armor was unveiled yesterday at an environmental museum in Brazil.
Dubbed Armadillosuchus arrudai, the newly described species of crocodile roamed the arid interior of Brazil about 90 million years ago, during the late Cretaceous period, scientists said.

The fossil hand of a long-necked, ostrich-like dinosaur recently found in China may help solve the mystery of how bird wings evolved from dinosaur limbs, according to a new study.
The ancient digits belonged to a 159-million-year-old theropod dinosaur dubbed Limusaurus inextricabilis. Theropods are two-legged dinos thought to have given rise to modern birds.

The fossilized leg of an 80-million-year-old duck-billed dinosaur has yielded the oldest known proteins preserved in soft tissue—including blood vessels and other connective tissue as well as perhaps blood cell proteins—a new study says.
The research was led by the team behind the controversial 2007 discovery of protein from similar soft tissues in 68-million-year-old Tyrannosaurus rex bones.
“It was not a one-hit wonder,” said John Asara of Harvard Medical School, who led the protein-sequence analysis.

Fossils help scientists peel back the layers of time to reveal stories of life from eras long past. Sometimes the story goes in an unforeseen direction; other fossils have a “wow” factor simply because they were discovered at all. Check out eight surprising fossil finds.

Digital x-ray images of a “bizarre” 300 million-year-old shark relative have revealed the oldest known fossilized brain, researchers announced yesterday.
The unusual discovery raises hopes that scientists will find other ancient brains and use them to study how gray matter has evolved, said John Maisey, a paleontologist at the American Museum of Natural History in New York.
