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.

A giant blade-crested spinosaurus, the “hell heron,” discovered in the Sahara

crest predator Niger fossil Dinosauria Spinosauria

Deep in the heart of the Sahara, scientists have uncovered Spinosaurus mirabilis — a spectacular new predator crowned with a massive, scimitar-shaped crest that may once have blazed with color under the desert sun. Discovered in remote inland river deposits in Niger, the fossil rewrites what we thought we knew about spinosaur dinosaurs, suggesting they weren’t fully aquatic hunters but powerful waders stalking fish in forested waterways hundreds of miles from the sea.

Triceratops had a giant nose that may have cooled its massive head

fossil Triceratops CT-scan skull

Triceratops’ massive head may have been doing more than just showing off those famous horns. Using CT scans and 3D reconstructions of fossil skulls, researchers uncovered a surprisingly complex nasal system hidden inside its enormous snout. Instead of being just a supersized nose for smelling, it likely housed intricate networks of nerves and blood vessels—and even special structures that helped regulate heat and moisture.
