These dinosaurs had wings but couldn’t fly

feather fossil Anchiornis Dinosauria bird

Some feathered dinosaurs may have briefly taken to the skies—only to give it up later. By studying rare fossils with preserved feathers, researchers uncovered a surprising clue hidden in molting patterns, revealing that Anchiornis likely couldn’t fly at all. Instead of the neat, symmetrical feather replacement seen in flying birds, these dinosaurs showed a messy, irregular molt—something only flightless animals exhibit.

400 million-year-old fish fossils reveal how life began moving onto land

Australia China fossil formation skull

Scientists have uncovered new clues about some of Earth’s earliest fish, shedding light on the ancient origins of vertebrates that eventually moved onto land. By reanalyzing mysterious fossils from Australia’s famed Gogo Formation and studying a newly reconstructed 410-million-year-old lungfish skull from China, researchers are revealing how these primitive creatures evolved.

This 2-pound dinosaur is rewriting what scientists know about evolution

fossil Alnashetri Alvarezsauria Dinosauria bird evolution skeleton

A nearly complete dinosaur skeleton discovered in Patagonia is helping scientists crack the mystery of alvarezsaurs, a bizarre group of bird-like dinosaurs. The fossil of Alnashetri cerropoliciensis reveals that these animals became tiny before developing their later specialized features, such as stubby arms and ant-eating adaptations. Weighing under two pounds, the dinosaur is one of the smallest known from South America.

Lost fossils reveal sea monsters that took over after Earth’s greatest extinction

predator Australia Madagascar fossil extinction

A lost cache of 250-million-year-old fossils from Australia has rewritten part of the story of life after Earth’s worst mass extinction. Instead of a single marine amphibian species, researchers uncovered evidence of a surprisingly diverse community of early ocean predators. One of these creatures had relatives stretching from the Arctic to Madagascar, showing that some of the first sea-going tetrapods spread across the globe with remarkable speed.

190-million-year-old “Sword Dragon” fossil rewrites ichthyosaur history

United Kingdom Jurassic fossil Ichthyosauria evolution skeleton

A newly identified ichthyosaur from the UK’s Jurassic Coast is rewriting part of the prehistoric playbook. Nicknamed the “Sword Dragon of Dorset,” the three-meter-long marine reptile lived during a poorly understood window of evolution when major ichthyosaur groups were disappearing and new ones emerging. Its beautifully preserved skeleton — complete with a blade-like snout and possible last meal — helps pinpoint when this dramatic transition occurred.
