More than 200 million years ago, a shadow traveled across the hot, arid landscape of what’s now the western United States. It belonged to a Late Triassic pterosaur that may have been the biggest of its time. Describing its size, features and home turf, researchers reveal this new Utah pterosaur is full of surprises.

The Peopling of the Americas: Evidence for Multiple Models

By Gemma Tarlach | August 8, 2018 1:00 pm

Exactly how and when the peopling of the Americas took place has long been one of the hottest debates in science. For every new paper that emerges with evidence of an interior or coastal route, it seems another team publishes contradictory conclusions. Authors of a new review of archaeological, geological and paleogenetic research have concluded that both of the two main models are reasonable — and that a couple fringe theories are most definitely not.

Flores Island’s Modern Pygmies And The “Hobbit” Homo Floresiensis

By Gemma Tarlach | August 2, 2018 1:00 pm
Indonesia's Flores Island, once home to the archaic "hobbit" human Homo floresiensis, still has some modern populations of a significantly smaller stature. Researchers sequenced DNA from several of the individuals to determine if they might be descended from the archaic hominin. (Credit: Australian Museum)

From the home of the “hobbit” (and I’m not talking about The Shire): Researchers have sequenced DNA from modern pygmy populations on the Indonesian island of Flores to determine whether they are descended from Homo floresiensis, a famously small-statured archaic human living there as recently as 50,000 years ago.

The Generalist Specialist: Why Homo Sapiens Succeeded

By Gemma Tarlach | July 30, 2018 10:00 am

Being a generalist specialist, a unique niche, is the hallmark of our species, say researchers — and the reason Homo sapiens (left) are still around but other hominins, including Neanderthals (right), are not. (Credit: Wikimedia Commons)

Some animals are jacks of all trades, some masters of one. Homo sapiens, argues a provocative new commentary, are an evolutionary success story because our ancestors pulled off a unique feat: being masterly jacks of all trades. But is this ecological niche, the generalist specialist, the real reason our species is the last hominin standing?

Meet Lingwulong, The “Amazing Dragon”

Lingwulong shenqi, a new dinosaur known from the fossils of multiple individuals, is a Jurassic surprise. It’s significantly older than other dinosaurs of its kind and is the earliest example found in China, challenging conventional ideas about the timing and spread of the four-legged plant-eaters. (Credit: Zhang Zongda)

Lingwulong shenqi, a newly described, 174-million-year-old dinosaur, is more than just another giant herbivore to add to the fossil record. Its age and location are unexpected, and upset notions about dino diversity and distribution during the Jurassic Period.

Scientists Claim They Found Bigfoot (The Brachiosaur, Anyway)

Found: Bigfoot! Or at least a brachiosaur foot that researchers nicknamed Bigfoot. A field researcher poses beside its partial remains in this 1998 photo. Foot bones are in foreground; vertebrae and other bones belong to a different animal. (Credit: Photo courtesy of the KUVP archives)

I don’t know about you, but nothing wakes me up in the morning quite like an announcement from a peer-reviewed journal declaring that paleontologists have found Bigfoot in the Black Hills region of the U.S.

Sooooo…yeah. Not quite. But they are claiming the dinosaur foot they found belonged to the biggest dino ever — which they nicknamed “Bigfoot.” Sneaky clickbait? Sure. But also some interesting science. Read on: The game is afoot.

Neanderthals Really Were All Fired Up

Production of fire was once thought to be a skill exclusive to Homo sapiens, but new research suggests our Neanderthal relatives could light it up as well. (Credit: Wikimedia Commons)

Fire at will! Researchers present evidence that Neanderthals were just as capable of producing fire as early Homo sapiens were, sending another long-held notion of our species’ exceptionalism up in smoke.

I’m not just fanning the flames here: The question of whether our closest evolutionary kin used fire the same way our ancestors did has been a controversial one for decades, and its debate mirrors broader trends in paleoanthropology.

Baby Snake Preserved In Amber Is Unprecedented Find

Snakes alive! Preserved in a piece of amber about the size of a small potato, a tiny snake hatchling — less than two inches long — is unprecedented in the fossil record. At nearly 100 million years old, the baby snake’s remains provide researchers with significant new information about the animals’ development and global distribution. But wait, there’s more…

First Americans: Gault Projectiles Point To Earlier Presence

Without human remains older than about 13,000 years, the best evidence for the earliest peopling of the Americas comes from stone tools such as the Gault projectiles, unique in shape, and other artifacts from a site in Texas. They represent previously unknown First Americans that pre-date Clovis, once thought to be the first indigenous culture in the New World. (Credit: Produced by N Velchoff ©The Gault School of Archaeological Research)

Amid a growing number of finds that challenge the long-held timeline of the peopling of the Americas, researchers get to the point: Artifacts found at a site in Texas, including projectile points of a previously unknown style, are at least 16,000 years old, pre-dating the conventional arrival date of First Americans.

Were Hominins In China 2.1 Million Years Ago?

Nearly a hundred stone tools excavated from multiple layers at a site in China point to hominins — our ancestors and closest kin — being in East Asia about 2.1 million years ago. The find is the oldest evidence of hominins outside of Africa by more than 200,000 years and begs the question: what species made them?
