This Dinosaur Found in Chile Had a Battle Ax for a Tail (Published 2021)
It’s not every day you find a dinosaur that defended itself from predators with a completely unique weapon. In a study published Wednesday in Nature, Chilean researchers announced the discovery of a new species of ankylosaur, a family of dinosaurs known for their heavy armor, from subantarctic Chile. The animal, which they named Stegouros elengassen, offers new clues about where these tank-like di
Over 200 Million Years Ago, Nature Called. It Was Full of Beetles. (Published 2021)
A 3-D model shows the insides of a coprolite, which preserved beetles and other material from a dinosaur ancestor’s gut. Video by Qvarnström et al.CreditCredit... Imagine a bunch of beetles minding their own business on an algae-covered rock. All of a sudden, they get hoovered up whole into the beak of a slim, long-necked dinosaur ancestor. R.I.P. — but on the bright side, through a complex combin
How the Largest Animals That Could Ever Fly Supported Giraffe-Like Necks (Published 2021)
If you were to gaze skyward in the late Cretaceous, you might catch a glimpse of surreal flying giants with wingspans that rival small planes. This supersized group of pterosaurs, known as azhdarchids, included species that measured 33 feet between wingtips, which made them the largest animals that ever took to the air. The extreme dimensions of azhdarchids raise tantalizing questions, such as how
Was This Dinosaur More Subaquatic Killer or Giant Wading Bird? (Published 2021)
Ninety-nine million years ago, a 55-foot dinosaur stalked the river deltas of North Africa. A sail on its back towered over the water as its crocodile-like jaws and curved claws made short work of car-size fish. This was Spinosaurus, discovered in 1915. Paleontologists have since debated how this creature lived. Did it prowl through currents in pursuit of prey, as recent research has suggested, or
Finally in 3-D: A Dinosaur’s All-Purpose Orifice (Published 2021)
The world’s oldest known all-purpose orifice sits in a fossil display case in the Senckenberg Natural History Museum in Frankfurt, Germany, so close to the glass that enshrines it that you can “put your face up to it, like this,” said Jakob Vinther, a paleontologist at the University of Bristol in England, holding his hand a couple inches from his nose. It belongs to a Psittacosaurus, a beaked, do
250 Million Years Ago, They Hibernated at the Bottom of the World (Published 2020)

Though its name means “shovel lizard,” it was more closely related to mammals.Credit...Crystal Shin How to tell if something that died 250 million years ago hibernated when it was alive? After all, hibernation — a state of reduced metabolism — is a good strategy for making it through long, harsh winters when food can be scarce. Biologist
Making Sense of ‘One of the Most Baffling Animals That Ever Lived’ (Published 2020)
An artist’s rendering of the Triassic Era aquatic reptile Tanystropheus. Its nine-foot neck contained only 13 vertebrae.Credit...Emma Finley-Jacob Nearly 250 million years ago, a very odd reptile patrolled the shorelines and coves of the Triassic Alps. Called Tanystropheus, it had a toothy head and a body echoing that of modern monitor lizards. But between them stretched a horizontal, giraffe-like
A Strange Dinosaur May Have Swum the Rivers of Africa (Published 2020)
An artist’s illustration of what Spinosaurus, one of the largest predatory dinosaurs yet found, may have looked like. A large, powerful tail may have been used for swimming.Credit...Davide Bonadonna An enigmatic predatory dinosaur that lived in northern Africa about 95 million years ago possessed a long, powerful tail that may have propelled it through water, new fossils suggest. If true, this bea
When Crocodiles Once Dived Like Dolphins and Whales (Published 2020)
An artist’s rendering of Cricosaurus suevicus, a Jurassic relative of modern crocodiles called thalattosuchians.Credit...Dmitry Bogdanov Some 400 million years ago, animals emerged from the ocean for the first time and began to thrive on land. But after eons of evolutionary experimentation, some lineages peaced out of the terrestrial world and embraced a full-time life at sea again. While whales a
An Elephant-Size Relative of Mammals That Grazed Alongside Dinosaurs (Published 2019)
An artist's reconstruction of Lisowicia bojani, a new species of dicynodont found in a clay pit in Poland.Credit...Karolina Suchan-Okulska You can call it a Triassic titan. Or a pre-Jurassic juggernaut. Just don’t call it a dinosaur. Despite its appearance, this burly behemoth was a completely different prehistoric beast: a dicynodont. Early relatives to present-day mammals, dicynodonts dominated
