represents the indigestible remains of a prehistoric meal, expelled by a predator near the end of the Cretaceous Period. Experts, including sea lily specialist John Jagt, identified at least two distinct species of crinoids—the biological group that...

routine pre-construction assessment revealed a deep, layered history stretching from the Neolithic era through the medieval period, with the Roman occupation representing the site’s most elaborate phase of use. From Ancient Barrow to Sacred Grounds The...

a rare glimpse into the fauna of the Bayan Gobi Formation, a continental deposit dating back to the Early Cretaceous period. Led by Lida Xing from the China University of Geosciences and the Dinosaur Odyssey Science Museum, the research team identified...

led by civil engineer Raghuvesh Tiwari, tested concrete samples containing 5%, 10%, and 15% biochar. After a 91-day curing period, the results were striking: the mixture with a 10% replacement of cement demonstrated a 21% increase in compressive...

Atacama Large Millimeter/submillimeter Array (ALMA) to monitor the precise movements of these protostars over an eight-year period. This extended timeline allowed the team to map the system’s orbital dynamics with enough precision to resolve its...

this is a difficult standard to uphold, given the significant climatic shifts in the region, most notably the African Humid Period. During that era, significantly higher rainfall would have dramatically altered the weathering rate of the limestone,...

of the autumn equinox to a series of planetary alignments and lunar spectacles, the coming months offer a sustained period of activity for both casual observers and dedicated astronomers. According to The Weather Network, the combination of cooling...

of the diversity and reproductive strategies of dinosaurs during the final millions of years of the Cretaceous period. Holotype of Shixingoolithus qianshanensis oosp.nov. from the Qianshan Basin, Anhui Province, East China. A) Two single dinosaur eggs...

titles have provided researchers with a wealth of data regarding the bureaucratic structure of the late Fifth Dynasty, a period often overshadowed by later eras in the historical record. Colorful wall carvings inside an Old Kingdom tomb at Saqqara,...

which depict the deceased offering food to deities and dining with his wife, suggests the tomb dates to the Ramesside period, specifically between 1292 and 1069 BC. While current assessments identify the owner as an official named Paser, experts are...

revealed a previously unknown species of dinosaur, providing a rare window into the smaller fauna of the Early Cretaceous period. Researchers from the University of Tsukuba suggest the find, which represents the oldest eggshell evidence ever recorded in...

cooling processes that occur in space, rather than the rapid cooling seen in Earth-based smelting. During the late Shang period (roughly 1600 to 1050 BC), regional smiths had mastered sophisticated bronze production, but widespread iron smelting did not...

as it requires absolutely no specialized equipment to identify. Future Trajectory and Shifting Perspectives This period of evening prominence is temporary. As Venus continues its trek along its orbit, it is steadily moving toward an event known as...

reptiles characterized by their modest size and unique evolutionary trajectory during the closing stages of the Cretaceous period. The fossilized remains, which include well-preserved sections of the skull, jaw, vertebrae, and limbs, were recovered from...

discovery confirms that basal alvarezsaurids continued to thrive in South America until the final stages of the Cretaceous period. These theropods were physically distinct, typically ranging between 0.5 and 2.5 meters in length. Characterized by...

uplift, equatorial areas experience subsidence. The rate of this deformation increased significantly during the study period. Between 1997 and 2000, the poles were rising at approximately 0.5 millimeters per year; by 2015, that velocity had doubled to...

societies remained largely intact, despite the significant societal shifts occurring across the Mediterranean during this period. Different laser scans reveal ancient ship carvings on a Kition Kathari temple block. Credit: International Journal of...
