A diagram of the dromaeosaurid dinosaur Pyroraptor olympius with selected fossil elements that can be reliably scaled using measurements given by Allain & Taquet (2000) to produce a realistic estimate of the taxon's size and proportions in life. This silhouette is based on the supposition of the missing elements of Pyroraptor's skeleton having fairly generalized dromaeosaurid proportions.

A legendary fossil is forcing scientists to rethink human origins
South Africa fossil human origin new species skeleton
One of the most complete human ancestor fossils ever found may belong to an entirely new species, according to an international research team. The famous “Little Foot” skeleton from South Africa has long been debated, but new analysis suggests it doesn’t truly match any known Australopithecus species. Instead, researchers say its unique mix of features points to a previously unidentified human relative, reshaping ideas about early human diversity.

bone pelvis Romania fossil Dinosauria Titanosauria skeleton
Scientists exploring Romania’s Hațeg Basin have discovered one of the densest dinosaur fossil sites ever found, with bones lying almost on top of each other. The K2 site preserves thousands of remains from a prehistoric flood-fed lake that acted like a natural bone trap 72 million years ago. Alongside common local dinosaurs, researchers uncovered the first well-preserved titanosaur skeletons ever found in the region. The site reveals how ancient European dinosaur ecosystems formed and evolved in

Israel fossil dating discovery Homo sapiens skeleton
Scientists have uncovered the world s earliest fossil showing both Neanderthal and Homo sapiens features: a five-year-old child from Israel s Skhul Cave dating back 140,000 years. This discovery pushes back the timeline of human interbreeding, proving that Neanderthals and modern humans were already mixing long before Europe s later encounters.
