Two of the fossils sampled for the study with the fossil melanosomes found in each fossil (scanning electron microscope images). Scaniacypselus to the left and Primotrogon to the right. Melanosome shape varies in the different samples, and is indicative of color. The sample furthest to the left was predicted to be iridescent.

Future climate analogs for the years 2020, 2050, 2100 and 2200 according to three well-established models. If greenhouse gas emissions are not curbed, the study says, the climate will continue to warm until it begins to resemble the Eocene in 2100. Credit: Courtesy of the authors

Transportable Array station P19K is one of the closest stations to the Iniskin earthquake origin. Solar panels power the station, and the seismometer is buried in a specially drilled borehole to insulate it from surface noise. Photo taken in 2017 during a service site visit by Incorporated Research Institutions for Seismology (IRIS). IRIS manages the Transportable Array station installation and maintenance.

This illustration shows the percentage of marine animals that went extinct at the end of the Permian era by latitude, from the model (black line) and from the fossil record (blue dots). A greater percentage of marine animals survived in the tropics than at the poles. The color of the water shows the temperature change, with red being most severe warming and yellow less warming. At the top is the supercontinent Pangaea, with massive volcanic eruptions emitting carbon dioxide. The images below the line represent some of the 96 percent of marine species that died during the event.
