Tardigrade fossil in 16-million-year-old amber a ‘once in a generation’ find

The microscopic «water bear» is as about as rare as they come.

A long, long time ago, a miniscule animal met its end in a sticky trap of tree resin. Sixteen million years later, that tiny tardigrade fossil was discovered in Dominican amber. It’s now something of a science celebrity. Talk about a glow-up.

The fossil tardigrade is remarkable for its rarity and for being a new species and a new genus.

Tardigrades are known as «water bears» due to their appearance when seen under a microscope (here’s what they look like when they walk). They’re nearly invincible, able to survive exposure to space and even being shot out of a gas gun (to a point).

While the fossil micro-animal looked like a modern tardigrade on the outside, researchers were also able to examine its innards. «Of all the currently known and formally named tardigrade amber fossils (three so far, including this Dominican amber fossil), this is the first fossil wherein we were able to visualize its internal structure (i.e. foregut),» Marc Mapalo, a doctoral candidate at Harvard University, told me. Mapalo is lead author of a paper on the find published this week in the journal Proceedings of the Royal Society B.

The tardigrade was so different from known specimens it earned its own genus and the name Paradoryphoribius chronocaribbeus.

«The discovery of a fossil tardigrade is truly a once-in-a-generation event,» said co-author Phil Barden in a New Jersey Institute of Technology statement on Tuesday. Barden’s lab found the fossil.

Spotting a teensy tardigrade that’s half a millimeter long in ancient amber is no easy feat. «At first I thought it was an artifact in the amber— a crack or fissure that just happened to look a lot like a tardigrade,» Barden said. The tiny claws tipped him off to what it really was.

Humans can buy tardigrade plush toys, tardigrade-emblazoned T-shirts and even tardigrade jewelry. «As microorganisms they live on a scale that is difficult to comprehend, yet they have these funny little legs and conspicuous cute faces that seem somehow familiar, like the bears they’re sometimes named after,» Barden said.

While more tardigrade fossils may yet be found in other amber samples, it’s a challenging mission.»You could spend the rest of your life screening through amber and never find one,» Barden said. He considers the discovery to be «enough tardigrade luck for one career.»

Mapalo hopes the find will encourage researchers to take care when studying amber and to keep their eyes peeled for the critters. The fossilized animals can tell us about how tardigrades have changed over time. There’s a lot left to learn about these mighty water bears, both ancient and modern.

You Can Watch an Exclusive Avatar: Fire and Ash Scene on TikTok Right Now

Disney and TikTok partner on an immersive content hub for James Cameron’s latest movie about the alien Na’vi.

If you’re not quite ready to head to the theater to watch Avatar: Fire and Ash, an exclusive scene preview might sell you on the visual spectacle. As part of a new collaboration with the social media giant, Disney is posting snippets of its new movie to its TikTok account.

This scene isn’t part of any trailer and won’t be posted to other social media accounts, making TikTok the only place you can view it — unless you buy a movie ticket. A first look at the new movie’s scenes isn’t the only Avatar-related bonus on the social media platform right now, either. TikTok has partnered with the house of mouse to bring an entire «immersive content hub» to the app.

A special section of TikTok includes quizzes and educational videos that explore the alien world of Pandora shown off in the movies. On TikTok, you can take a personality quiz to find out what Na’vi clan you most closely align with and unlock a special profile picture border to use on your account.

Science and fiction blend together with a series of videos from real doctors who explain the basis for some of Avatar’s world-building. If you want to learn about exoplanets or how realistic the anatomy of the movie’s alien animals is, these videos will feed your brain while still providing entertainment value.

Perhaps the most enticing part of Disney’s latest social media collaboration is the opportunity for fans to win prizes and trips. TikTok creators who make edits with the #TikTokAvatarContest hashtag are entered into a competition to win Avatar merchandise. The biggest winners will be able to take a trip to visual effects studio Wētā Workshop in New Zealand or visit Avatar director James Cameron’s Lightstorm Entertainment Studio in Los Angeles.

Avatar: Fire and Ash is the third installment in director Cameron’s cinematic passion project. While the first Avatar movie was released in 2009, Cameron didn’t release another entry in the franchise until 2022. In total, there is a five-movie arc planned for the indigo alien Na’vi on the moon of Pandora.

The Avatar movies are known for pushing the boundaries of CGI visual effects in cinema. They are also historically big winners at the box office: the original Avatar is the highest-grossing film of all time, earning $2.9 billion across its theatrical releases. Its sequel, Avatar: The Way of Water, is the third-highest-grossing film of all time, trailing Avengers: Endgame. You can stream those movies on Disney Plus.

It remains to be seen whether Avatar: Fire and Ash will financially live up to its predecessors. The film currently has mixed reviews from critics on Rotten Tomatoes.
