About 66 million years in the past, an asteroid slammed into Earth and the planet out of the blue went darkish.
The affect and its aftermath have been catastrophic. Tsunamis inundated coastlines, earthquakes rattled the bottom, acid rain poured from the skies and wildfires scorched the terrain. Roughly 75 % of species, together with all nonavian dinosaurs, went extinct.
That day is the middle of “Affect: The Finish of the Age of the Dinosaurs,” a brand new exhibition on the American Museum of Pure Historical past in New York Metropolis. “There’s little doubt — effectively, arguably not less than — that it was the worst day of the final half billion years,” says Roger Benson, the museum’s curator of dinosaur paleobiology.
Guests first step into life earlier than doomsday. Inside a dimly lit corridor, a life-size mannequin of a mosasaur, a marine reptile, assaults a long-necked plesiosaur. Close by, a Triceratops adorned with quills — a controversial speculation primarily based on fossilized pores and skin — tears down a small tree. That diorama, primarily based on fossils from the Hell Creek formation in North Dakota, consists of different animals similar to turtles, birds and a Didelphodon, an extinct predatory mammal harking back to a Tasmanian Satan.
There’s extra to do than take a look at dioramas. One interactive show quizzes guests on their every day habits to search out out what Cretaceous critter they’re most like. One other performs sounds of sure animals, together with Beelzebufo, a big predatory frog.
Then, affect.
A 6-minute movie in a small theater describes, in excessive element, the destruction wrought by a Mount Everest–sized asteroid crashing into Earth with the pressure of 10 billion atomic bombs. The asteroid immediately vaporized in a blast zone hotter than the floor of the solar. Its collision despatched trillions of tons of rocks into the sky, blocking most daylight for a yr and a half. Many vegetation, and the animals who ate them, died. Right here, the exhibition’s dim lighting feels deliberate — the room’s darkness makes an already grim matter really feel weightier.
Within the subsequent room, the as soon as thriving Triceratops is now a pile of bones and guests can scent the wildfires. Spotlights draw consideration to shows describing how researchers have constructed the case that an asteroid triggered the mass extinction occasion, together with the invention of the Chicxulub crater off the coast of Mexico. A big globe exhibits the a whole bunch of spots the place scientists have discovered iridium, a uncommon steel and an indication of extraterrestrial affect.
Lacking is point out of one other speculation: volcanism. That’s as a result of the broad scientific consensus is that the asteroid affect was largely accountable, says Denton Ebel, a curator within the museum’s division of Earth and Planetary Sciences. “We don’t want volcanoes. The affect alone explains it,” Ebel says. “Explains the timing, explains the knife edge in historical past that’s recorded within the rock report.”
The asteroid’s destruction made means for brand new life. Throughout the corridor, guests learn the way traits similar to the flexibility to interrupt open nuts helped some animals survive within the aftermath and the way rainforests crammed emptied landscapes. They will additionally discover out whether or not their Cretaceous creature from the sooner quiz lived or died. Because the world recovered, an Age of Mammals started that persists at the moment.
There’s a small probability that one other large asteroid affect may threaten Earth. However the exhibit notes that with at the moment’s know-how, we might see it coming and hopefully stop one other devastating asteroid affect. An interactive show permits guests to apply themselves, redirecting an asteroid’s path with lasers or with a probe, akin to NASA’s DART mission.
For individuals who could fear about an impending apocalypse, “Affect: The Finish of the Age of the Dinosaurs” is a reminder {that a} thriving world thrown into chaos can finally thrive once more.
