The ‘one who causes fear’ – new meat-eating dinosaur discovered

by

Research published in the peer-reviewed Journal of Vertebrate Paleontology describes a newly discovered species of dinosaur – named the ‘one who causes fear’, or Llukalkan aliocranianus.

Around 80 million years ago as tyrannosaurs ruled the Northern Hemisphere, this lookalike was one of 10 currently known species of abelisaurids flourishing in the southern continents.

A fearsome killer, Llukalkan was “likely among the top predators” throughout Patagonia, now in Argentina, during the Late Cretaceous due to its formidable size (up to five meters long), extremely powerful bite, very sharp teeth, huge claws in their feet and their keen sense of smell.

World’s first dinosaur preserved sitting on nest of eggs with fossilized babies

by

The fossil in question is that of an oviraptorosaur, a group of bird-like theropod dinosaurs that thrived during the Cretaceous Period, the third and final time period of the Mesozoic Era (commonly known as the ‘Age of Dinosaurs’) that extended from 145 to 66 million years ago.

The new specimen was recovered from uppermost Cretaceous-aged rocks, some 70 million years old, in Ganzhou City in southern China’s Jiangxi Province.

“Dinosaurs preserved on their nests are rare, and so are fossil embryos. This is the first time a non-avian dinosaur has been found, sitting on a nest of eggs that preserve embryos, in a single spectacular specimen,” explains Dr. Shundong Bi.

Fermented wool is the answer to why colors of Iron Age rug are so vivid

by

The Pazyryk carpet is the world’s oldest example of a knotted-pile carpet and is kept at the State Hermitage Museum in St Petersburg, Russia.

The carpet, which was made out of new wool at around 400 BC, is one of the most exciting examples of central Asian craftsmanship from the Iron Age.

Ever since the carpet was discovered in 1947 by Russian archaeologists in a kurgan tomb in the Altai mountains, experts in traditional dyeing techniques have been puzzled by the vivid red, yellow and blue colours of the carpet, which lay buried in extreme conditions for almost two thousand five hundred years.

New technology allows scientists first glimpse of intricate details of Little Foot’s life

by

In June 2019, an international team brought the complete skull of the 3.67-million-year-old Little Foot Australopithecus skeleton, from South Africa to the UK and achieved unprecedented imaging resolution of its bony structures and dentition in an X-ray synchrotron-based investigation at the UK’s national synchrotron, Diamond Light Source. The X-ray work is highlighted in a new paper in e-Life, published today (2nd March 2021) focusing on the inner craniodental features of Little Foot.

Little Foot is the nickname given to a nearly complete Australopithecus fossil skeleton found in 1994-1998 in the cave system of Sterkfontein, South Africa.

The remarkable completeness and great age of the Little Foot skeleton makes it a crucially important specimen in human origins research and a prime candidate for exploring human evolution through high-resolution virtual analysis.

To recover the smallest possible details from a fairly large and very fragile fossil, the team decided to image the skull using synchrotron X-ray micro computed tomography at the I12 beamline at Diamond, revealing new information about human evolution and origins. This paper outlines preliminary results of the X-ray synchrotron-based investigation of the dentition and bones of the skull (i.e., cranial vault and mandible).

CT scans of Egyptian mummy reveal new details about the death of a pivotal pharaoh

by

Modern medical technology is helping scholars tell a more nuanced story about the fate of an ancient king whose violent death indirectly led to the reunification of Egypt in the 16th century BC. The research was published in Frontiers in Medicine.

Pharaoh Seqenenre-Taa-II, the Brave, briefly ruled over Southern Egypt during the country’s occupation by the Hyksos, a foriegn dynasty that held power across the kingdom for about a century (c. 1650-1550 BCE).

In his attempt to oust the Hyskos, Seqenenre-Taa-II was killed. Scholars have debated the exact nature of the pharaoh’s death since his mummy was first discovered and studied in the 1880s. [Read more…] about CT scans of Egyptian mummy reveal new details about the death of a pivotal pharaoh
