a sandstone layer nicknamed “Tim’s Confession,” which yielded nearly a thousand fragments of upper and lower jaws bearing teeth. The creature belongs to the omomyids, an extinct lineage of true primates that occupied a position near the base of later...

and they’ve been a great help to us.” Recovering such minute remains is challenging; for many ancient primates, only teeth and jaw fragments endure the ravages of deep time. “Identifying ancient primate fossils in the field typically requires hunting...

Tainrakuasuchus bellator was modest in size for its era. Its anatomy featured a long neck, a slender jaw lined with sharp teeth, and a back shielded by bony plates known as osteoderms—structures also present in contemporary crocodiles, indicating an...

on the frontal bone, classified as Nihilichnus hastarius. Its dimensions and structural characteristics align with the teeth of Purussaurus neivensis, the most formidable crocodyliform within the La Venta fossil record. Biomechanical modeling of the...

Girl research. © Science Advances Despite the passage of time, the grave held fragile biological remnants, including hair, teeth, fingernails, and even traces of brain tissue. A cowskin hide lining the coffin provided a distinct impression of her body,...

pairs of shoes and clothing positioned as if a person had collapsed within them, there has never been a trace of bones, teeth, or other biological remains. Even as advanced submersibles have maneuvered through the vessel’s interior, the wreck remains...

the woman was roughly 48 years old at the time of her passing, with physical indicators of age present in her joints and teeth. Although her arms were positioned at her sides—a posture usually reserved for royalty—the study confirmed she was not a...

Y. yangyuanensis had forelimbs that were roughly one-third shorter than its hind limbs. This morphology, paired with slender teeth and a lightweight skull, points to a predator well-adapted for running rather than soaring. Comparisons with 377 living...

preserved in tooth enamel. The analysis targeted amelogenin Y, a protein exclusive to the male Y chromosome, by examining 23 teeth from a minimum of 20 distinct individuals. The test returned no trace of the protein. The Cell paper reporting the work...

context adds weight to the idea that some spinosaurids hunted in freshwater systems instead of roaming open oceans. The teeth of S. mirabilis interlock like puzzle pieces, with upper and lower rows sliding past each other. This arrangement is ideal for...

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 civilization. The...

only partial lower jaws, the specimens yielded a wealth of information. Researchers employed micro‑CT scanning to render the teeth in three dimensions and then compared them with a broad sample of extinct and living marsupials. The study, published in...

and reproductive anatomy. Compared with E. tripunctata, the new crab possesses a flatter carapace, sharper triangular teeth along the front edge, and a pronounced notch and groove on the frontal region. Additional raised ridges on the shell are absent...

canid Mesocyon coryphaeus is bridging a 150‑year knowledge gap that previously relied almost entirely on isolated skulls and teeth. Named by paleontologist E. D. Cope in 1879, the specimen now offers a rare glimpse into the animal’s full anatomy,...

to the study published in Palaeontologia Electronica, the animal possessed a slender, high‑crowned skull and finely ridged teeth, traits that imply a diet of small bony fish. Its integument appears to have been smooth, consistent with other members of...

of 11th-century ‘Conquest Man’ ©Liverpool John Moores University The findings suggest a life defined by mobility. While his teeth display strontium levels consistent with the local Barton environment, oxygen isotope data hint that he spent his formative...

Genetic analysis ultimately confirmed that the specimen was unique. Scientists believe Lielaphis slashi uses specialized teeth at the back of its mouth to consume small lizards and eggs, posing no threat to humans. Conservation in a Changing Landscape...

against ship rigging—which caused catastrophic trauma when turned against infantry. Advanced analysis of the soldiers’ teeth has allowed researchers to trace the origins of these men to a concentrated 30-mile region in northwestern Europe. The ongoing...

remnants indicate a much heavier, more muscular build than its modern counterparts. It was equipped with sharp, powerful teeth and a set of distinctive, fang-like tusks on the roof of its mouth, adaptations that likely made it an efficient hunter of...

to thrive in a variety of environments. Her adaptations allowed her to exploit both terrestrial and arboreal resources. Her teeth and jaw structure suggest a diet that included fruits, nuts, seeds, and possibly small animals. This omnivorous diet,...
