Disease 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...

Credit: Chuang Zhao Tiny Dental Calculus Provides Genetic Key Initial attempts to extract DNA from the skull’s bone and teeth proved futile, as the genetic material was too degraded. The breakthrough arrived from fossilized dental calculus—commonly...

that inhabited Earth roughly 150 million years ago. This iconic animal bridges dinosaurian and avian morphologies, featuring teeth, clawed digits, feathered wings, and a plumaged tail. Biomechanical calculations revealed that while Archaeopteryx lacked...

specimens offer a rare glimpse into the postcranial anatomy of a lineage otherwise known primarily from fragmentary skulls, teeth, and finger bones found in sites like Siberia’s Denisova Cave and the Tibetan Plateau. The Denisovan femur and tibia known...

of these feet reflects the animal’s ecological niche, researchers liken them to the diagnostic value of mammalian teeth. By analyzing the structural nuances of the 450-million-year-old feet, the team identified distinct differences between this ancient...

Context Alnashetri was built for speed, sporting long, slender legs designed for traversing sand dunes. With a set of sharp teeth, it likely occupied an ecological niche as an active hunter of small prey, including insects, lizards, snakes, and early...

remains a challenge, though researchers suspect it was likely a fish or perhaps a bottom-dwelling shark with specialized teeth capable of crushing hard biological structures, as reported by the Smithsonian. The nature of the fossil has sparked nuanced...

the challenges of reconstructing ancient ecosystems in Japan, where fossil evidence is typically limited to isolated teeth or fragmented bone rather than complete skeletons. Size Variation in Coastal Ecosystems The new morphological analysis confirms...

Biological Record The investigation traced the virus’s timeline back to the Bronze Age, identifying its presence in sheep teeth recovered from pastoralist settlements in the Eurasian steppe. Samples from sites in modern-day Kazakhstan and Russia, dating...

distinct from its more famous cousin, the American mastodon, characterized by thicker leg bones, unique tusks, and narrower teeth optimized for browsing on woody vegetation rather than grazing. During the Pleistocene epoch, these creatures inhabited a...

their imposing stature, which has fueled imagination for centuries, oarfish are gentle creatures. They lack the specialized teeth of typical predators, subsisting instead on a diet of plankton and small crustaceans. While a typical specimen measures...

were physically distinct, typically ranging between 0.5 and 2.5 meters in length. Characterized by birdlike skulls, small teeth, and highly specialized forelimbs—which featured a singular massive claw on a shortened arm—these animals occupy a unique...

swath of the continent, including samples from Brazil, Colombia, Peru, and Venezuela. By analyzing DNA extracted from bone, teeth, fur, and muscle tissue, the team confirmed four previously proposed species—Leopardus guttulus, Leopardus emiliae,...
