Helicoprion For Over 100 Years, The Spiral Tooth Fossils Of Helicoprion Have Baffled Everyone Who Tried

Helicoprion For over 100 years, the spiral tooth fossils of Helicoprion have baffled everyone who tried to figure them out, and more theories were proposed than you can believe (see top of picture). In the last year, some CT scans done by Leif Tapanila at Idaho State and coauthors have finally nailed down the location of the tooth-whirl: in the throat! The best idea of its purpose is ratcheting its catch down the throat. You can see the current, accepted reproduction at the bottom of the picture (by great Paleo-artist Ray Troll). -MrA Fossil image source: https://en.wikipedia.org/wiki/Helicoprion#/media/File:Spirale_dentaire_d%27helicoprion.jpg

10 Ways to BBQ on an Alien World

There are over 3,700 planets in our galaxy. Many of them orbit stars outside our solar system, these are known as exoplanets. Spend a summer weekend barbecuing it up on any of these alien worlds.

(WARNING: Don’t try any of this on Earth—except the last one.)

1. Lava World

Janssen aka 55 Cancri e

10 Ways To BBQ On An Alien World

Hang your steak on a fishing pole and dangle your meat over the boiling pools of lava on this possible magma world. Try two to three minutes on each side to get an ashy feast of deliciousness.

2. Hot Jupiter

Dimidium aka 51 Pegasi b

10 Ways To BBQ On An Alien World

Set your grill to 1800 degrees Fahrenheit (982 degrees Celsius) or hop onto the first exoplanet discovered and get a perfect char on your hot dogs. By the time your dogs are done, it’ll be New Year’s Eve, because a year on this planet is only four days long.

3. Super Earth

HD 40307 g

10 Ways To BBQ On An Alien World

Super air fry your duck on this Super Earth, as you skydive in the intense gravity of a planet twice as massive as Earth. Why are you air frying a duck? We don’t know. Why are you skydiving on an exoplanet? We’re not judging.

4. Lightning Neptune

HAT-P-11b

10 Ways To BBQ On An Alien World

I’ve got steaks, they’re multiplying/and I’m looooosing control. Cause the power this planet is supplying/is electrifying!

Sear your tuna to perfection in the lightning strikes that could flash across the stormy skies of this Neptune-like planet named HAT-P-11b.

5. Red Earth

Kepler-186f

10 Ways To BBQ On An Alien World

Tired of all that meat? Try a multi-colored salad with the vibrant plants that could grow under the red sun of this Earth-sized planet. But it could also be a lifeless rock, so BYOB (bring your own barbecue).

6. Inferno World

Kepler-70b

10 Ways To BBQ On An Alien World

Don’t take too long to prep your vegetables for the grill! The hottest planet on record will flash-incinerate your veggies in seconds!

7. Egg-shaped

WASP-12b

10 Ways To BBQ On An Alien World

Picture this: You are pressure cooking your chicken on a hot gas giant in the shape of an egg. And you’re under pressure to cook fast, because this gas giant is being pulled apart by its nearby star.

8. Two suns

Kepler-16b

10 Ways To BBQ On An Alien World

Evenly cook your ribs in a dual convection oven under the dual stars of this “Tatooine.” Kick back and watch your two shadows grow in the fading light of a double sunset.

9. Takeout

Venus

10 Ways To BBQ On An Alien World

Order in for a staycation in our own solar system. The smell of rotten eggs rising from the clouds of sulfuric acid and choking carbon dioxide will put you off cooking, so get that meal to go.

10. Take a Breath

Earth

10 Ways To BBQ On An Alien World

Sometimes the best vacations are the ones you take at home. Flip your burgers on the only planet where you can breathe the atmosphere.

Grill us on Twitter and tell us how bad our jokes are.

The Ammonoids The Ammonoids Are A Subclass Of Cephalopods That Inhabited The Oceans From The Devonian

The Ammonoids The Ammonoids are a subclass of cephalopods that inhabited the oceans from the Devonian some 416 million years ago until they went extinct some 65 million years ago. The species evolved and dispersed rapidly around the world and so are some of the best guide fossils for dating the strata in which they are found.

Okay, the title of The Atlantic’s article might be a little click-bait-y. But the discovery is truly remarkable. A new bone has been analyzed from the already-famous cave in Russia, and it belonged to, per DNA analysis, the daughter of a Neanderthal mother and a Denisovan father.
