The World’s Largest Collection of Fossilized Poop Opens in Florida

The South Florida Museum unveiled, perhaps, its greatest gift to the world last weekend. On October 3, the museum opened an exhibit of the world’s largest collection of fossilized deuces. 

The 1277 prehistoric turds, called coprolites, were verified by officials from the Guinness Book of World Records in August. (More than 30 other samples could not be authenticated as feces, and had to be thrown away.) The “Amazing Coprolite Collection” is on loan for the year from Jacksonville resident George Frandsen, who runs the Poozeum, an online exhibit of some incredibly well-preserved stools.

The collection includes dumps from species who lived in 15 states and eight countries. It may sound like a bizarre tourist attraction, but coprolite specimens are actually valuable for paleontologists. Poop doesn’t often survive millennia, and it can provide important data about what prehistoric species ate (and what kinds of infestations they had). Sometimes bones, scales, and teeth from the digested prey survive within the coprolite, too. The nuggets of ancient waste products in the archive come from crocodile-like species, fish, frogs, and more.

The largest poop stone of the bunch, from a prehistoric crocodile, is nicknamed “Precious,” as in Gollum’s favorite accessory in Lord of the Rings. That’s the puppy-sized turd pictured in the top image above. A national treasure!

10 Surprising Ways Senses Shape Perception
The American Museum of Natural History
The American Museum of Natural History

Every bit of information we know about the world we gathered with one of our five senses. But even with perfect pitch or 20/20 vision, our perceptions don’t always reflect an accurate picture of our surroundings. Our brain is constantly filling in gaps and taking shortcuts, which can result in some pretty wild illusions.

That’s the subject of “Our Senses: An Immersive Experience,” a new exhibition at the American Museum of Natural History in New York City. Mental Floss recently took a tour of the sensory funhouse to learn more about how the brain and the senses interact.

1. LIGHTING REVEALS HIDDEN IMAGES.

Under normal lighting, the walls of the first room of “Our Senses” look like abstract art. But when the lights change color, hidden illustrations are revealed. The three lights—blue, red, and green—used in the room activate the three cone cells in our eyes, and each color highlights a different set of animal illustrations, giving the viewers the impression of switching between three separate rooms while standing still.

2. CERTAIN SOUNDS TAKE PRIORITY ...

We can “hear” many different sounds at once, but we can only listen to a couple at a time. The AMNH exhibit demonstrates this with an audio collage of competing recordings. Our ears automatically pick out noises we’re conditioned to react to, like an ambulance siren or a baby’s cry. Other sounds, like individual voices and musical instruments, require more effort to detect.

3. ... AS DO CERTAIN IMAGES.

When looking at a painting, most people’s eyes are drawn to the same spots. The first things we look for in an image are human faces. So after staring at an artwork for five seconds, you may be able to say how many people are in it and what they look like, but would likely come up short when asked to list the inanimate object in the scene.

4. PAST IMAGES AFFECT PRESENT PERCEPTION.

Our senses often are more suggestible than we would like. Check out the video above. After seeing the first sequence of animal drawings, do you see a rat or a man’s face in the last image? The answer is likely a rat. Now watch the next round—after being shown pictures of faces, you might see a man’s face instead even though the final image hasn’t changed.

5. COLOR INFLUENCES TASTE ...

Every cooking show you’ve watched is right—presentation really is important. One look at something can dictate your expectations for how it should taste. Researchers have found that we perceive red food and drinks to taste sweeter and green food and drinks to taste less sweet regardless of chemical composition. Even the color of the cup we drink from can influence our perception of taste.

6. ... AND SO DOES SOUND

Sight isn’t the only sense that plays a part in how we taste. According to one study, listening to crunching noises while snacking on chips makes them taste fresher. Remember that trick before tossing out a bag of stale junk food.

7. BEING HYPER-FOCUSED HAS DRAWBACKS.

Have you ever been so focused on something that the world around you seemed to disappear? If you can’t recall the feeling, watch the video above. The instructions say to keep track of every time a ball is passed. If you’re totally absorbed, you may not notice anything peculiar, but watch it a second time without paying attention to anything in particular and you’ll see a person in a gorilla suit walk into the middle of the screen. The phenomenon that allows us to tune out big details like this is called selective attention. If you devote all your mental energy to one task, your brain puts up blinders that block out irrelevant information without you realizing it.

8. THINGS GET WEIRD WHEN SENSES CONTRADICT EACH OTHER.

The most mind-bending room in the "Our Senses" exhibit is practically empty. The illusion comes from the black grid pattern painted onto the white wall in such a way that straight planes appear to curve. The shapes tell our eyes we’re walking on uneven ground while our inner ear tells us the floor is stable. It’s like getting seasick in reverse: This conflicting sensory information can make us feel dizzy and even nauseous.

9. WE SEE SHADOWS THAT AREN’T THERE.

If our brains didn’t know how to adjust for lighting, we’d see every shadow as part of the object it falls on. But we can recognize that the half of a street that’s covered in shade isn’t actually darker in color than the half that sits in the sun. It’s a pretty useful adaptation—except when it’s hijacked for optical illusions. Look at the image above: The squares marked A and B are actually the same shade of gray. Because the pillar appears to cast a shadow over square B, our brain assumes it’s really lighter in color than what we’re shown.

10. WE SEE FACES EVERYWHERE.

The human brain is really good at recognizing human faces—so good it can make us see things that aren’t there. This is apparent in the Einstein hollow head illusion. When looking at the mold of Albert Einstein’s face straight on, the features appear to pop out rather than sink in. Our brain knows we’re looking at something similar to a human face, and it knows what human faces are shaped like, so it automatically corrects the image that it’s given.

A Secret Room Full of Michelangelo's Sketches Will Soon Open in Florence

Parents all over the world have chastised their children for drawing on the walls. But when you're Michelangelo, you've got some leeway. According to The Local, the Medici Chapels, part of the Bargello museum in Florence, Italy, has announced that it plans to open a largely unseen room full of the artist's sketches to the public by 2020.

Roughly 40 years ago, curators of the chapels at the Basilica di San Lorenzo had a very Dan Brown moment when they discovered a trap door in a wardrobe leading to an underground room that appeared to have works from Michelangelo covering its walls. The tiny retreat is thought to be a place where the artist hid out in 1530 after upsetting the Medicis—his patrons—by joining a revolt against their control of Florence. While in self-imposed exile for several months, he apparently spent his time drawing on whatever surfaces were available.

Museum officials previously believed the room and the charcoal drawings were too fragile to risk visitors, but have since had a change of heart, leading to their plan to renovate the building and create new attractions. While not all of the work is thought to be attributable to the famed artist, there's enough of it in the subterranean chamber—including drawings of Jesus and even recreations of portions of the Sistine Chapel—to make a trip worthwhile.
