Paleontologists Uncover First Evidence of a Multi-Species Dinosaur Herd

Paleontologists have uncovered footprints that are 76 million years old, belonging to a dominant group of Ceratopsian dinosaurs, in Dinosaur Provincial Park, Alberta, Canada. This remarkable finding is the first indication of herd behavior among mixed dinosaur species, reminiscent of how modern wildebeests and zebras flock together on the African savannas.

Dinosaur Provincial Park, located in southern Alberta, Canada, is one of the premier regions in the world for studying late Cretaceous terrestrial ecosystems.

The park yields hundreds of dinosaur skeletal remains and a vast array of bones and teeth, making it a prime location for exploring dinosaur evolution, behavior, biological introduction, and paleoecology.

Despite the wealth of skeletal remains, dinosaur footprints and trackways are surprisingly uncommon.

“In 2024, we discovered a new track site, a skyline track site containing ‘typical’ natural mold tracks that had not been identified in the park before,” stated Dr. Phil Bell and his colleagues at the University of New England.

At this site, paleontologists uncovered 13 Seratopsia (horned dinosaurs) tracks, showing at least five animals walking side by side, along with an ankylosaurus (armored dinosaur) that might have been walking among them.

They were also intrigued to find two large Tyrannosaurus tracks alongside the group. Additionally, a footprint from a smaller meat-eating dinosaur was also discovered.

“I have been collecting dinosaur bones in Dinosaur Provincial Park for nearly two decades, but I had never given much thought to footprints,” remarked Dr. Bell.

“The edge of this rock had a mud-like appearance that caught between my toes, which immediately intrigued me.”

“The Tyrannosaurus tracks give the impression that they are truly observing the herd.”

“It was thrilling to see them walking in the footprints of dinosaurs 76 million years after they went extinct,” said Dr. Brian Pickles from Reading College.

“Using innovative search techniques, we were able to locate several additional track sites throughout the park’s diverse terrain. We will provide further details on how these captivating creatures interacted and behaved in their ecosystems.”

“This discovery highlights the vast amount left to uncover in dinosaur paleontology,” noted Dr. Caleb Brown, PhD, from the Royal Tyrrell Museum of Paleontology.

“Dinosaur Park boasts one of the world’s most comprehensive dinosaur collections and studies, with over a century of dedicated research. Only now are we beginning to fully explore the potential of dinosaur trackways.”

The findings are published in a paper in the journal PLOS 1.

Interview: Will Whitney Wolfe Herd Make Us Fall in Love with Dating Apps Again?

It was Andrei Andrev, the head of Badoo and co-creator of Bumble. After Bumble was involved, you faced another workplace scandal. In 2019, Forbes published a survey accusing Badoo’s London headquarters of fostering a toxic, sexist work environment. He denied these allegations, but shortly after the article’s release, he sold his majority stake. It’s remarkable that you had to navigate a second high-profile case of suspected misconduct from a man in your professional life. How do you handle that now?
The reality is quite frightening. It’s the worst-case scenario. I felt deeply concerned for anyone who experienced it. I was unaware of any such allegations. Many assumed, “Whitney knows everything and is covering for him.” The truth is, I was busy managing Bumble as a standalone business in Austin. It’s not like I was present at [Badoo’s London]. I was courageously working in the office every day and interacting with those individuals. When Forbes called me, I was taken aback. It was vital for Andrei to be transparent about my personal interactions with him. Honestly, I never witnessed anything to that extent. However, I never doubted women’s accounts or anyone else’s experiences, and I communicated that. I believe these allegations surfaced years prior and were not current.

There have been numerous allegations from different periods. Correct. But I think most of this article addresses the earlier ones. I’m not trying to distance myself from anything; that’s not my intention. Reflecting on the early 2010s, we’ve all seen the images of WeWork and Uber. When you envision tech companies in 2012, do you picture a progressive office environment? I doubt it. What insights can you draw from that time? Perhaps I was merely in one specific situation, or it was a broader theme reflective of the prevalent tech culture back then.

That period was marked by significant technological optimism. Countless apps emerged, backed by incomprehensible funding, promising to tackle numerous global issues. Did you believe that back then? I certainly did. Having access to an app that allowed you to see people nearby and connect with them was revolutionary. Without such an interface, dating someone you’d never met before felt truly transformative. I could even summon an Uber black car. We were living in a remarkable era—if Gen Z is listening now, they might think, “What were these people doing? Were they living in the dark ages?” [Laughs]

Listen, I vividly recall the era before smartphones. You know where I’m leading with this. The leap in efficiency and convenience was astounding. It was hard to believe we were at the forefront of such a transformation. Achieving that level of critical mass twice is incredibly challenging; it’s often understated. Many people don’t grasp how difficult it is; they might think, “She’s just lucky, wearing yellow, and she’s blonde.”

In the subsequent Bumble phase, you experienced substantial growth during the pandemic as everyone turned to the app. It was a pivotal moment. Released in 2021, it echoed loudly, yet user growth began to taper off the following year. What do you believe contributed to that? In my opinion, the early years of running this company were defined by a quantitative approach. Phone manufacturers reached out to us early on, eager to feature our brand. They proposed pre-installing our app on every phone so that it showed up on users’ home screens, resulting in millions of downloads. I was grateful, but many questioned my approach, claiming it was the wrong way to grow. This isn’t a social network; it’s a two-sided market where one person needs to connect with someone similar. Flooding the system won’t help—just as you wouldn’t want to meet everyone on the streets of New York City, why would anyone want to do that in an app? It’s more than just a scrolling content platform. Growth skyrocketed during the pandemic and additional phases, which was welcomed as a transformational era.

Mark Aitken Captures Collie’s Struggle to Herd Lambs in Stunning Mobile Phone Photos

debtMark Aitken has been working on a photo series in Lapland for the past two years. The Presence of Absence“The work explores the delicate, sometimes eerie, boundary between life and death experienced by people living in this extreme climate and landscape,” he says.

Aitken, who was born in New Zealand, grew up in South Africa and has lived in London for many years, took the photo on a sheep farm this spring. “Kukkola is a small village on the Finnish-Lapland border on the Tornio River close to Sweden. The farm has been running for 20 years and this lamb is one of around 100 born in March and April,” Aitken says.

The lamb doesn’t have a name, but the inquisitive collie does: “He’s a lively young male called Possu, which means piglet. I saw the two animals interacting when I went into the barn to find Jaana, one of the farm owners, and arrange a time to take her portrait.”

Aitken usually shoots on 35mm film and likes to take his time preparing to take a photograph, especially when working with people. “When the right atmosphere, light and mood is achieved, I press the shutter. I like this discipline. This process also applies to printing in the darkroom. Only then does the memory of that moment become associated with the photograph.”

That day, he didn’t have his camera with him, but he did have his iPhone SE, and before his eyes the theme of his series was playing out in a whole new way: “I was amazed and intrigued by the inter-species relationships. The possu were trying to herd the lambs, but they were failing. The lambs hadn’t yet learned fear.”
