Despite Earth's most devastating mass extinction wiping out over 80% of marine life and half of land species, a group of early reptiles called archosauromorphs not only survived but thrived, venturing across the supposedly lifeless tropics to eventually evolve into the dinosaurs and crocodiles we know today. Armed with a groundbreaking model dubbed TARDIS, researchers have reconstructed their ancient dispersal routes, revealing how these resilient reptiles conquered a hostile, post-apocalyptic Earth.
Imagine a crocodile built like a greyhound -- that's a sebecid. Standing tall, with some species reaching 20 feet in length, they dominated South American landscapes after the extinction of dinosaurs until about 11 million years ago. Or at least, that's what paleontologists thought. A new study shows the Caribbean Islands were a refuge for the last sebecid populations at least 5 million years after they went extinct everywhere else.
The idea that dinosaurs were already in decline before an asteroid wiped most of them out 66 million years ago may be explained by a worsening fossil record from that time rather than a genuine dwindling of dinosaur species, suggests a new study.
The Arctic landscape during the Cretaceous Period may have been dominated by the dinosaurs, but the rivers and streams held something more familiar. Alaska's fresh waters 73 million years ago were teeming with the ancient relatives of today's salmon, pike and other northern fish. A new article has named three new species of fish from that time period, including a salmonid, dubbed Sivulliusalmo alaskensis.
A new study is reshaping how scientists date dinosaur fossils in Alberta's Dinosaur Provincial Park (DPP). Using advanced drone-assisted 3D mapping, researchers have uncovered significant variations in a key geological marker, challenging long-standing methods of determining the ages of dinosaur fossils.
A newly discovered, raccoon-sized armored monstersaurian from the Grand Staircase-Escalante National Monument in Southern Utah, United States, reveals a surprising diversity of large lizards at the pinnacle of the age of dinosaurs.
Yale University ecologists reveal a lizard lineage that rode out the dinosaur-killing asteroid event with unexpected evolutionary survival traits. Night lizards (family Xantusiidae) survived the Cretaceous–Paleogene (K-Pg) mass extinction event 66 million years ago (formerly known as the K-T extinction) despite having small broods and occupying limited ranges, a departure from the theory of how other species are thought to have persisted in the aftermath of the event.
Astronomers have discovered a galaxy that has been "frozen in time" for billions of years. Like a celestial dinosaur fossil, this galaxy could reveal the secrets of cosmic evolution.
A university student on a fossil-hunting field trip in Dorset made a stunning discovery: a 145-million-year-old jawbone belonging to a previously unknown mammal species with razor-like teeth. With the help of CT scanning, 3D printing, and expert analysis, the fossil was revealed to be Novaculadon mirabilis, a multituberculate that lived alongside dinosaurs. This is the first find of its kind from the area in over a century, and the fossil’s preservation and sharp-toothed structure are offering new insights into early mammal evolution — all thanks to a beach walk and a sharp eye.
