Newly found dinosaur fossils shed light on toothless, two-fingered species

Here’s a look at what the Oksoko avarsan dinosaurs might have looked like way back when.

Newly discovered fossils of a toothless, parrot-like dinosaur species that lived more than 68 million years ago reveal a creature with two fingers on each forearm. That’s one less digit than its close dino relatives had. 

The fossils imply that the dinosaurs may have evolved forelimb adaptations that enabled them to spread during the Late Cretaceous Period, researchers say in a new study published Wednesday in The Royal Society Open Science journal. Paleontologists from the University of Edinburgh found a number of complete skeletons of the new species during a dig in Mongolia’s Gobi Desert. 

The feathered, omnivorous Oksoko avarsan grew to around 6.5 feet (2 meters) long. In addition to two functional digits on each

Toothless, parrot-like dinosaur thrived 69 million years ago, study finds

Multiple skeletons of the Oksoko avarsan, a feathered omnivorous dinosaur that grew to 2 meters in length, were dug up in the Gobi Desert in Mongolia by researchers from the University of Edinburgh, according to a news statement published Tuesday.

It had a large, toothless beak like modern-day parrots and just two digits on each forearm — one less than its close relatives.

It’s the first time scientists have seen evidence of digit loss among oviraptors, a family of three-fingered dinosaurs.

Evolving to have fewer digits suggests they could also “alter their diets and lifestyles, and enabled them to diversify and multiply,” according to the statement.

The “very complete” juvenile skeletons were found resting together, showing that young Oksoko avarsan roamed in groups, said paleontologist Gregory Funston, a post-doctoral researcher at the University of Edinburgh who led the study.

“But more importantly, its two-fingered hand prompted us to look at

First Fossil Feather Ever Found Belonged to This Dinosaur

The feather looks like any feather you might find on the ground. But it’s not. It’s about 150 million years old, and it fluttered to the ground back when the dinosaurs roamed what is today called Bavaria. It’s entombed in limestone, and, when paleontologists unearthed it in 1861, it became the first fossil feather ever discovered.

Many paleontologists think the feather came from archaeopteryx lithographica, a creature that, with its feathered wings and sharp-toothed mouth, bears features of both dinosaurs and birds, making it a herald of the evolutionary transition between the two groups.

But that first-known fossil feather isn’t attached to an archaeopteryx skeleton, and so for more than a century, not all scientists have agreed on the identity of the feather’s owner.

“There’s been this debate, even when the feather was found: Does this isolated feather belong to the same animal as these skeletal specimens of archaeopteryx?” said

Latest TSMC 7nm Data Proves Intel And Other Dinosaur Chipmakers Aren’t Even Close To Dying Yet. A Strong Base Of Revenues For TSMC (NYSE:TSM)

Where new school techies and old school dinosaur investors clash heads is on historical versus future success. No story is better represented by that than the still-smoldering battlefield between armchair investors about Intel (INTC) and AMD (AMD). I don’t need to educate most anyone about the scathing response by Wall Street to Intel’s production delay into 7nm. We don’t need a dissection of the stock chart for AMD to comprehend that they are currently priced to rob Intel of massive market share in processors.

I won’t take a stand on that hairy debate, or on other similar discussions that really illustrate the growing divide between “growth” and “value”, though the same nuts and bolts concept I provide with this analysis on TSMC’s (TSM) recent results can be applied to other hardware debates (and maybe one I can elaborate on if there’s enough interest):
