Saber-Toothed Mummy!
A saber-toothed cub died about 35,000 years ago, but its body is amazingly well preserved.

This saber-toothed cub died at least 35,000 years ago, but the ice preserved most of its body.
Saber-toothed cats are best known for their giant canine teeth. But what did they really look like? A newly discovered mummy of a saber-toothed cub is providing some answers.
The cub, which was found in 2020 in Siberia, Russia, died at least 35,000 years ago of unknown causes. It was about three weeks old. The cub’s body was well preserved because it was in a layer of permanently frozen ground called permafrost. Its face, neck, and front legs, as well as part of its torso, are all in excellent condition, and so is its dark brown fur. Amazingly, it still has whiskers and claws.
“It’s a fantastic feeling to see with your own eyes the life appearance of a long-extinct animal,” researcher Alexey V. Lopatin told CNN. “Especially when it comes to such an interesting predator as the saber-toothed cat.”
The cub was of a species called Homotherium latidens. There were several varieties of saber-toothed cats, including Homotherium and Smilodon. They all had enormous upper canine teeth that, for Smilodon, could reach 8 inches (20 centimeters) in length. (Homotherium teeth were closer to 3 inches in length.) Not surprisingly, these big-toothed big cats were carnivores (meat eaters). All varieties of saber-toothed cats were extinct by about 10,000 years ago.

Since saber-toothed cats no longer exist, scientists have had to use fossils to try to figure out what they looked like. But the mummy is helping to paint a clearer picture. For example, scientists are learning the locations of the animal’s muscles. From this, they can learn more about how saber-toothed cats hunted their prey.
Saber-toothed cats are related to today’s big cats, like lions and tigers—but there are many differences. Scientists compared the mummified cub with modern lion cubs and noted some of these distinctions. The saber-toothed cat mummy had darker fur, smaller ears, and a larger mouth than a lion cub. Its paws were wider and rounder.
Paleontologist Jack Tseng, who was not part of the team that studied the mummy, is excited about the possibilities for learning from this mummy. Tseng told CNN that he’s amazed when he thinks about “the treasure trove of information that could come out of this singular discovery.”

Scientists recently concluded that the giant teeth of the saber-toothed cat Homotherium latidens could not be seen when its mouth was closed. This is the opposite of what they previously believed.

Pits Full of Fossils!

Scientists have discovered tons of fossils right in the middle of what’s now Los Angeles, California! That’s because Los Angeles is home to big pools of tar that stopped countless ancient animals in their tracks.
Now called the La Brea Tar Pits, the pools of tar were used for years by humans. American Indians used the tar to help make their canoes waterproof. When Europeans moved to California, they used the tar to put roofs on their homes. Sometimes, people would find animal bones in the tar, but no one knew how old the bones were.
In the early 1900s, scientists discovered that many of the bones weren’t just old but ancient. They belonged to a variety of animals, many of which are now extinct.
Scientists believe these animals became trapped in the tar. Unable to move, the animals attracted predators (like saber-toothed cats), which then also became trapped.
Scientists have found more than one million bones at the La Brea Tar Pits, plus many fossilized plants. And they’re still finding more!
