Extraordinary fossils solve a 500-million-year mystery: Bryozoans were there at the dawn of animal life

Extraordinary fossils solve a 500-million-year mystery: Bryozoans were there at the dawn of animal life Stephanie Baum Scientific Editor Robert Egan Associate Editor Bryozoans are tiny, filter-feeding colonial invertebrates that thrive in the world's oceans today, yet for decades their origins presented a puzzling gap in the fossil record. While nearly every other major animal group made its first appearance during the Cambrian explosion roughly 530 million years ago, the bryozoan fossil...

Fossil fishes buried in the desert reveal a missing chapter in marine history

Fossil fishes buried in the desert reveal a missing chapter in marine history Gaby Clark Scientific Editor Andrew Zinin Lead Editor When an asteroid struck Earth about 66 million years ago, it ended the age of dinosaurs and transformed life across the planet. The effects of that catastrophe are visible in the fossil record on land, but scientists know far less about what happened to fishes in the seas during the first few million years after the extinction. Like many people during the...

A lack of sex held back life's diversity for millions of years, fossil study finds

A lack of sex held back life's diversity for millions of years, fossil study finds Sadie Harley Scientific Editor Robert Egan Associate Editor The way that Earth's first animals reproduced held back life's diversity for millions of years, until stress and competition led to the development of sexual reproduction, which in turn accelerated the pace of evolution. Researchers from the University of Cambridge studied fossils from the oldest-known animals on Earth, dating from 574 million years...

Why dirty farm plastic matters: Cleaner mulch film could cut landfill waste and fossil fuel use

Why dirty farm plastic matters: Cleaner mulch film could cut landfill waste and fossil fuel use Sadie Harley Scientific Editor Andrew Zinin Lead Editor Nearly a billion pounds of plastic film mulch is used in American agriculture each year, and most of it is dumped into landfills. New research from Washington State University shows that recycling could be a feasible alternative, reducing reliance on fossil fuels and keeping plastics out of the waste stream. The researchers recycled plastic...
