offers a window into the symbolic life of the Magdalenian people. Among the collection are ornate pendants crafted from the bones of deer, horses, and bison. Most striking is a rare aurochs bone featuring delicate engravings of both an aurochs and a...

to achieve powered flight, coexisting with dinosaurs. Some species boasted wingspans of up to 12 meters, and their hollow bones—resembling those of modern birds—may increase the likelihood of exceptional preservation when conditions are favorable. The...

are lodged in rabbits in sockets or alveoli so it is called thecodont dentition. But in frogs, teeth are fused with the jaw bones. The teeth found in the rabbit are situated only on the edges of the jaws, while the vomerine teeth are absent. Teeth found...

of the Eurasian cave lion, a species that disappeared roughly 14,000 years ago. A study published in PLOS ONE details bones bearing clear marks of human modification. These findings suggest that humans were actively hunting these apex predators,...

at distinct moments: the older layer formed about 1.55 million years ago, and a later one around one million years ago. The bones sandwiched between these horizons thus fall within that intervening interval, offering the first substantial fossil...

point for cultural exchange. Hidden Himalayan Lineage Unearthed Through Genomic Analysis To determine the age of the bones, the scientists first applied radiocarbon dating. They then isolated DNA from the bones and associated tissue, comparing the...

caused by free radicals. It is also essential for the synthesis of collagen, a protein that provides structure to the skin, bones, and connective tissues. Additionally, vitamin C plays a crucial role in the absorption of iron, a mineral necessary for...

the sheer scale of the fossils, which required heavy machinery like forklifts for extraction, and the fragile state of the bones. Paleontologist and co-author Scott Hocknull emphasized the intensity of the work, noting that the team had to meticulously...

require careful preparation as the surrounding sandstone is painstakingly removed. The articulated nature of the remaining bones hints at rapid burial, a scenario that can favor soft‑tissue preservation, prompting researchers to monitor each removal...

A 90-million-year-old fossil discovered in Fukushima, Japan, reveals that diverse iguanodontian dinosaurs once thrived in Late Cretaceous coastal ecosystems. A fossilized bone unearthed in 1999 and left largely unexamined for over two decades has...

wolves, and mammoths, it also preserves a suite of smaller organisms that often escape attention. Amphibians, whose delicate bones seldom fossilize, provide a unique window into ancient climate and vegetation patterns because they remain tightly linked...

a startling cause for the collapse of its great cities. Excavations in a trench at Bhirrana, Haryana, have yielded animal bones and teeth that record five millennia of climate change, prompting a major revision of the timeline for the Indus Valley...

Profiles The study, appearing in the International Journal of Osteoarchaeology, documents how these children’s teeth and bones bear lesions traditionally linked to treponemal disease. Historically, such congenital markers have been interpreted as strong...

New forensic analysis of bones found on a remote Pacific island is reigniting the mystery of what truly happened to Amelia Earhart after her 1937 flight. A specialized team of 17 researchers, supported by Purdue University and the Archaeological Legacy...

Variations of leukocyte count occur in many infectious, hematologic, inflammatory, and neoplastic diseases. Variations of leukocyte count occur in many infectious, hematologic, inflammatory, and neoplastic diseases. Therefore, laboratory evaluation of...

Reticulocytes are young or juvenile red cells released from the bone marrow into the bloodstream and that contain remnants of ribonucleic acid (RNA) and ribosomes but no nucleus. Reticulocytes are young or juvenile red cells released from the bone...

A lone Thai dinosaur fossil, found without the usual bone pile, uncovers a previously unidentified feature, reshaping our understanding. Researchers have announced a new sauropod species from northeastern Thailand, naming it Uragasaurus kalasinensis....

Contexts Archaeologists identified two distinct zones spaced roughly 30 metres apart. One zone contained human and animal bones, while the other held a small assemblage of Maya ceramic vessels. The findings have given rise to the Cenote Yaakun Research...
