On the small island of Denman, located off the coast of British Columbia, paleontologists have just discovered a caudal vertebra—nearly 80 million years old—embedded in sedimentary rock. And it didn’t belong to just anyone! In the journal Facets, Victoria M. Arbour, Timon S. Bullard, and David C. Evans reveal that this bone belongs to an ornithomimosaur—a theropod (two-legged) dinosaur known for its speed and a morphology closely resembling that of our modern-day ostrich.

For the first time, this fossil provides proof that these “bird-mimic lizards”—the literal translation of their Latin name—once roamed the Pacific coasts of North America during the Cretaceous period.

Brought to Light After More Than Two Decades
Although these dinosaurs belonged to the theropod family—the same family as some of the era’s largest predators (such as Tyrannosaurus and Velociraptor)—their appearance was vastly different from that of their sharp-toothed cousins. However, they possessed two long, feathered legs, an equally feathered long neck, a toothless beak, and a slender body—features the researchers have depicted as being covered in feathers. Some species, such as Gallimimus or Ornithomimus, could exceed 7 meters in length. Moreover, scientists believe they were omnivorous and ranked among the fastest dinosaurs of their time. Their estimated top speed was 60 kilometers per hour.

The fossil under study consists of a tail vertebra from a specimen that lived during the Late Cretaceous period, approximately 75 to 80 million years ago. This treasure was discovered in August 1999 within marine sediments that formed in the area of ​​the present-day Cedar District—on Denman Island in western Canada—before subsequently falling into obscurity.

A Carcass That May Have Floated There?
Paleontologist David Evans and his team point out that this represents, to date, the “second known example of a dinosaur fossil found in the Nanaimo region”—and, more importantly, the first to be recovered from Canadian rock outcrops in the area. But how did the bone of this terrestrial animal end up lodged in such a spot? The report’s authors suggest that the carcass of this ornithomimosaur may have been swept away by the sea or scavengers. It may have disarticulated offshore.

According to them, this dinosaur “probably” lived on the western flank of ancient North America, at a latitude comparable to that of other regions on the eastern side of the continent—areas known to have supported a rich fauna. On the Pacific coast, traces of dinosaur activity remain extremely rare. However, this does not mean that they did not inhabit the region. Paleontologists are convinced that the mountain ranges in this zone isolated certain populations for millions of years.

The Botswana government says the huge 2,492-carat diamond is the second-biggest ever discovered in a mine. It’s the biggest diamond found since 1905.

The as-yet-unnamed diamond was presented to the world at the office of Botswana President Mokgweetsi Masisi. It weighs approximately half a kilogram and Masisi was one of the first to get to hold it.

“It is overwhelming,” Masisi said. “I am lucky to have seen it in my time.” He gasped and said “wow” before calling senior government officials over to take a closer look.

Officials said it was too early to value the stone or decide how it would be sold. Another smaller diamond from the same mine in Botswana was sold for $63 million in 2016. This set a record for a rough gem.

“This is history in the making,” said Naseem Lahri, Botswana managing director for Lucara Diamond Corp., the Canadian mining company that found the diamond. “I am very proud. It is a product of Botswana.”

Lucara said in a statement Wednesday that it recovered the “exceptional” rough diamond from its Karowe Mine in central Botswana. Lucara said it was a “high-quality” stone and was found intact. It was located using X-ray technology designed to find large, high-value diamonds.

“We are ecstatic about the recovery of this extraordinary 2,492-carat diamond,” Lucara President and CEO William Lamb said in a statement.

The weight would make it the largest diamond found in 119 years. It would also make it the second-largest ever dug out of a mine after the Cullinan Diamond that was discovered in South Africa in 1905. The famous Cullinan was 3,106 carats and was cut into gems. Some of these form part of the British Crown Jewels.

Scientists may have finally solved the riddle of Tyrannosaurus rex’s small arms. These arms have always stood out as the oddest feature in the mightiest of dinosaurs and are frequently discussed in context with Tyrannosaurus tiny arms fossil dinosaur discoveries. As a result, they have prompted jokes and a century-plus debate on their purpose and evolutionary history.

At about 3 feet long, the arms of T. rex were less than a third of the length of the dinosaur’s legs. Notably, they looked disproportionate in a body that could span more than 40 feet in larger adults. Interestingly, many Tyrannosaurus tiny arms fossil dinosaur specimens show this dramatic size contrast.

T. rex was one of many meat-eating dinosaurs with puny arms. Over the years, scientists have come up with theories for the forelimbs’ function, including holding or pinning down prey and impressing potential mates during courtship. More recent studies have suggested that the arms became smaller to reduce the risk of being bitten during feeding frenzies. Meanwhile, a longstanding theory is that they are simply vestigial — they had no practical purpose and therefore shrank. But a consensus is lacking. Therefore, the Tyrannosaurus tiny arms fossil dinosaur question still intrigues paleontologists today.

Now, a new study published May 20 in the journal Proceedings of the Royal Society B aims to settle the debate once and for all. The study analyzed 85 species of dinosaurs and concluded that tiny arms were an evolutionary trade-off. In particular, another body part became ever larger and took up resources — the skull.

“If you’re a dinosaur with a very strongly put together skull, chances are you’re going to have very small forelimbs,” said Charlie Roger Scherer, a doctoral student in the department of Earth sciences at University College London and the study’s lead author. “And it doesn’t really matter how big you are — you could be 1 ton in weight, or 10 tons in weight. If you have a strong skull, you’re going to have relatively small arms.” As a result, the Tyrannosaurus tiny arms fossil dinosaur mystery is closely connected to skull strength and functionality.

The reason is that “evolution doesn’t like to have everything all at once,” as Scherer put it, because it tends to prioritize one thing over another. “If you want to focus on using your head to bring down large prey, you don’t really want to be putting much effort in keeping your arms long and with claws, because you’re probably not really going to need that, so evolution kind of says, ‘We don’t need the arms anymore, so let’s shrink them down and put more energy into keeping the skull strong and using that as the primary weapon.’”

Previous research already suggested a link between shrinking forelimbs and growing skulls in carnivorous dinosaurs. However, the new study is the first, according to Scherer, to identify this trend in five different groups of dinosaurs and add statistical support to the theory.
