Evolutionary Biologists Say Recently Discovered Fossil Shows Transition of a Reptile From Life on Land to Life in the Sea

Johns Hopkins Medicine

Using modern research tools on a 155-million-year-old reptile fossil, scientists at Johns Hopkins and the American Museum of Natural History report they have filled in some important clues to the evolution of animals that once roamed land and transitioned to life in the water.

Plesiosaur Flippers Inspire a Steering Mechanism for Swimming Robotic Vehicle

American Physical Society's Division of Fluid Dynamics

Plesiosaurs, who thrived during the early to middle Jurassic Period, used four paddlelike flippers of nearly equal size and musculature to swim. Despite the seemingly subpar engineering, the fossil record reveals that plesiosaurs were widespread and prolific. This inspired a team in the U.K. to explore how swimming with four flippers might be advantageous compared to two. They’ll present their work during the 70th meeting of the Division of Fluid Dynamics, Nov. 19-21, 2017.

Fossil That Fills Missing Evolutionary Link Named After UChicago Professors

University of Chicago

Scientists recently announced the discovery of a fossil that fills a missing evolutionary link—the first known member of the modern bryozoans to grow up into a structure. Called Jablonskipora kidwellae, it is named after UChicago geophysical scientists David Jablonski and Susan Kidwell.

UWM Geologists Uncover Antarctica’s Fossil Forests

University of Wisconsin-Milwaukee

Prehistoric polar forests were built for survival, but were not hardy enough to live in ultra-high concentrations of atmospheric carbon dioxide. A UWM geologist is studying the tree fossil record in Antarctica from a mass extinction 250 million years ago, looking for clues to how greenhouse gases affected plants -- then and now.
