These strange layers of fossils suggest that recurring drought was a big problem for the animals, which were members of the genus Lystrosaurus, meaning "shovel lizard" in ancient Greek. Lystrosaurs were rare survivors of the Permian-Triassic mass extinction, a period of runaway climate change 252 million years ago that killed an estimated 70% of land vertebrates and 96% of marine animals.

ADVERTISEMENT: History & Archaeology Cryptic 4,000-year-old writing system may finally be deciphered (Photo courtesy of the Metropolitan Museum of Art) A mysterious ancient writing system called Linear Elamite, used between about 2300 B.C. and 1800 B.C. in what is now southern Iran, might have finally been deciphered, although some experts are skeptical about the findings. What's more, it's unclear whether all the artifacts used to decipher the writings were legally acquired.

At the north end of Louisiana State University's (LSU) campus sit two grassy mounds, rising in a gentle slope to a height of about 20 feet (6 meters). The mounds are just two of more than 800 similar human-made mounds in Louisiana, built by Indigenous Americans. Although researchers knew they were old, a new study has determined just how old these ancient structures are.

NASA had mostly fueled its first Space Launch System (SLS) megarocket to launch the Artemis 1 moon mission on Monday when launch controllers were unable to chill one of the four main engines to the temperatures needed to handle its super-cold propellant. The issue stalled plans to launch the SLS rocket and its uncrewed Orion spacecraft on an ambitious 42-day test flight around the moon. Liftoff was scheduled for 8:33 a.m. EDT (1233 GMT).

This mission, named Artemis 1, is the first of three planned Artemis missions that will culminate in 2025 with astronauts setting foot on the moon for the first time in 50 years, and will include the first woman and person of color ever to do so.
