Remains of embryos entombed in their fish mothers' wombs for 380 million years have been found in fossils from an ancient rock outcrop in Western Australia. The finding is a big deal because it ...

Researchers in Australia have uncovered the oldest record of live birth — viviparity — in any vertebrate (see page 650). The discovery of embryos in fossils of placoderms (ancient, armoured, jawed ...

The placoderms were a diverse group of ancient armoured fishes and it’s widely believed that they are ancestral to virtually all vertebrates alive today, including humans. Placoderms dominated aquatic ...

An international team of scientists has described a rare fossil site that is believed to be among the earliest evidence of different fish species using a common nursery — much like ones utilized by ...

Sex is an ancient tradition. It’s older than today’s continents, older than dinosaurs, older than trees, dating back to a time when vertebrate life thrived in the seas but had not yet ventured onto ...

When an Australian scientist uncovered an ancient-looking placoderm skull in the 1960s, he thought he'd cracked the code on an evolutionary mystery. This so-called 'platypus fish,' scientists had ...
