How did a relative of the red panda end up in North America? What can this tell us about how long ago – and how many times – North America was connected to Europe and Asia?

There's a group trying to save the functionally extinct northern white rhino using in vitro fertilization. But the ethics around using assisted reproductive technologies to save endangered animals are far from simple.

Throughout the Pleistocene Epoch, the range of the woolly rhino grew and shrank in sync with global climate. So what caused the climate -- and the range of the woolly rhino -- to cycle back and forth between such extremes?

It arose from rhino ancestors that were a lot smaller, but Paraceratherium would take a different evolutionary path. Believe it or not, it actually became so big that it probably got close to what scientists think might be the actual...

Despite the name, we don’t know where the so-called “hell pigs” belong in the mammalian family tree. They walked on hooves, like pigs do, but had longer legs, almost like deer. They had hunched backs, a bit like rhinos or bison. But as...

We all know ducks quack, dogs bark, and birds chirp, but that barely scratches the surface of all the amazing ways animals have devised to talk to each other!

One of the most dynamic, transformative, and potentially dangerous features in North America is also responsible for some of the continent's most amazing fossil deposits. It's a supervolcano we now call Yellowstone.

What has tough skin, a tiny tail, and a big horn on its nose? A rhino! Join Jessi and Squeaks and learn all about these super cool, super strong animals!

Two extinct relatives of horses and rhinos are closely related to each other but have strikingly different body plans. How did two of the same kind of animal, living in the same place, end up looking so different?

At least one entire class of dinosaurs seems to have had feathers, including velociraptors, and probably T. rex. Find out how we know, and how we even know what color some of them were!

Unicorns may not exist on this planet, but Earth does have plenty of one-horned creatures that are just as remarkable, if not quite as majestic.

Should We Let Pandas Go Extinct?

In the savannahs of Kenya, two female northern white rhinos, Nájin and Fatu, munch contentedly on grass. They are the last two known northern white rhinos left on Earth. Their species is functionally extinct— without a male, they can't...

Save the Vaquita Day is the first Saturday after the 4th of July, and it serves as a reminder that preventing extinctions means acting early.

We know how to clone animals, so why aren't we saving endangered species by cloning their populations?

Scientists have found that the fertility rate of captive rhinos is being compromised. What they're doing to fix it.

This newborn rhino doesn't know it yet, but its existence is very important. Yair Ben-Dor has more.

Follow along with a rhino keeper as she takes you on a tour of a one-of-a-kind, 1,800-acre exhibit recreating the African and Asian savannas.

Every rhino calf born is important to the population.

Most diets that are fed to rhinos at zoos are associated with low fertility. Here's how scientists are fixing that.

Her birth is significant due to the southern white rhino's endangered status.
