Strange sea-dwelling reptile fossil hints at rapid evolution after mass extinction

Two hundred and fifty million years ago, life on earth was in a tail-spin—climate change, volcanic eruptions, and rising sea levels contributed to a mass extinction that makes the death of the dinosaurs look like child’s play. Marine life got hit hardest—96% of all marine species went extinct. For a long time, scientists believed that the early marine reptiles that came about after the mass extinction evolved slowly, but the recent discovery of a strange new fossil brings that view into question.

“Hammerhead” creature was world’s first plant-eating marine reptile

In 2014, scientists discovered a bizarre fossil—a crocodile-sized sea-dwelling reptile that lived 242 million years ago in what today is southern China. Its head was poorly preserved, but it seemed to have a flamingo-like beak. But in a paper published today in Science Advances, paleontologists reveal what was really going on—that “beak” is actually part of a hammerhead-shaped jaw apparatus, which it used to feed on plants on the ocean floor. It’s the earliest known example of an herbivorous marine reptile.

How to Beat Extinction: Live Fast, Die Young

When you don’t know if you have much of a future, you focus more on the now—there’s no point in biding your time and waiting when you could die any day. It seems that evolution follows this rule too—a recent study published by Field Museum scientists in Scientific Reports reveals that for Lystrosaurus (pygmy hippo-sized mammal relatives that lived with the dinosaurs), when the going got tough, the tough got busy.

Nesting: How Scientific Collections Helped Reveal an Artist’s Inspiration

The Field Museum is home to 30 million specimens that get sent around the world—most of the time, they’re used for scientific research, but this time, they wound up in an art museum right here in Chicago. The Art Institute of Chicago has a new exhibition featuring Van Gogh’s paintings of bedrooms that explores his artistic influences and the concept of home. His fascination with homes included a collection of birds’ nests that became the subject matter of several of his paintings.

Saving a River from Poison

The Putumayo River is home to some of the purest water in the Amazon basin—but maybe not for long. The huge Amazon tributary forms the border between Colombia and Peru, draining from giant Amazonian forests, orchid-covered peatlands, and, most presciently, soil bearing traces of gold. But mining that gold has the unfortunate side-effect of poisoning the water with mercury.

“Fire Frogs” and Eel-like Amphibians: Meet The Field’s Newest Fossil Discoveries

Two hundred and seventy-eight million years ago, the world was a different place. Not only were the landmasses merged into the supercontinent of Pangaea, but the land was home to ancient animals unlike anything alive today. But until now, very little information was available about what animals were present in the southern tropics.
