A majority of living mammals today are nocturnal—and conventional wisdom tells us that this transition to nocturnality occurred as mammals evolved from their early mammal ancestors, synapsids, about 200 million years ago. It’s largely assumed that those synapsids were diurnal—active mostly during the daytime—but The Field Museum’s Kenneth Angielczyk, Associate Curator of Paleomammalogy and co-author Lars Schmitz, Assistant Professor of Biology, Keck Science Department, Claremont McKenna, Pitzer and Scripps Colleges, wanted to put it to the test.

Wherein we take an adventure into the deep oceans of history in pursuit of fossilized sharks. Shout-out to Bill Simpson for his help in the production of this video and lending us the fossilized shark specimens for the shoot! We want to thank Ray Troll (http://www.trollart.com/) for generously allowing us to incorporate his incredible illustrations in this video! Read more about Fossil Sharks

The citizen science project, called Project MERCURRI, is designed to compare microbes from different environments on Earth both to each other and to those found on the International Space Station. All together, 48 microbial species were selected to blast into orbit aboard the SpaceX Falcon 9 shuttle to the International Space Station for research later this month.

Everyone knows that Tyrannosaurus rex was the biggest and baddest thing around during the age of the dinosaurs. But what else was out there? What was the biggest thing before the T. rex? Scientists at The Field Museum and collaborators have uncovered the bones of another large predator in the Cedar Mountain Formation in Utah – one that would have filled the role as top predator of its time and kept T. rex’s ancestors in check!
