Scientists say it's "almost certain" that debris from the Chicxulub asteroid that led to the mass extinction of the dinosaurs can be found on the moon.

It has been proved by many researches that asteroids are responsible for the extinction of dinosaurs from the Earth. But, another new information related to this, has come to the fore. Recently released conclusions of a research has said that "about 66 million years ago a 10-kilometer asteroid hit the Earth, causing such a severe earthquake that the Earth was shaking for several months". About 1023 joules of energy was emitted from that earthquake. That's mean, this energy was more than 50 thousand times the energy released by the 9.1 magnitude earthquake in Sumatra in 2004.

“A new space-based surveyor that will help catalog millions of near-Earth objects is now ready for budgeting and building after passing a rigorous technical review.

This year NASA completed its first-ever mission organized entirely for the purpose of planetary defense, when the DART probe slammed into an asteroid to see if it could be redirected away from a potential collision course with Earth.

Now, the NEO Surveyor mission will discover and characterize at least 90% of the near-Earth objects more than 140 meters (460 feet) across that come within 30 million miles of our planet’s orbit.

These objects are capable of causing significant regional harm, while history has shown that larger ones can be catastrophic. Humanity has gotten lucky thus far, but slow-growing wisdom has seen NASA create a Planetary Defense Coordination Office for the purpose of learning how to protect Earth from such events...

“Ground-based telescopes remain essential for us to continually watch the skies, but a space-based infrared observatory is the ultimate high ground that will enable NASA’s planetary defense strategy.”

Sitting around 1 million miles from Earth at the First LaGrange Point, NEO Surveyor will view the solar system in the infrared spectrum of light, lightwaves that are blocked by Earth’s atmosphere and therefore invisible for ground-based telescopes...

The launch date is currently proposed for June 2028.” -via Good News Network, 12/23/22

Dinofact #20

The most supported theory of the cause of the Cretaceous-Paleogene Extinction Event is the bolide impact hypothesis, which states that most the dinosaurs (excepting aves, modern-day birds) were extincted by a meteor impact. This theory, proposed by Walter Alvarez, Luis Alvarez, and colleagues in 1980, is supported by increased iridium deposits worldwide and the Cretaceous-Paleogene boundary, as well as shocked quartz, also found worldwide. In 1991, a massive crater measuring 180 km (110 mi) wide was discovered in the Yucatán Peninsula of southeastern Mexico. Evidence suggests that an extraterrestrial projectile approximately 5 to 15 kilometers (3 to 9+1⁄2 miles) wide impacted the site 66 million years ago, causing a chain of tsunamis, earthquakes, wildfires, and other disasters, that led to an "impact winter", leading to the extinction of all dinosaurs except for grain-eating birds.

text from porter robinson's "goodbye to a world"

every single animal in this comic is extinct. it's not too late for the ones that are left.

edit: thanks @mudcrabmassacre for the correction, smilodon fatalis did not in fact go extinct in 1023 AD. the actual prediction is around 10,000 years ago - I think i may have missed a zero or two.

so the Spouse and I like to have a lot of verbal discussions about the universe where the asteroid didn't hit. mainly spec evo stuff. what would evolve into what, that kind of thing. we know we're not alone in that.

we maintain that humans evolved alongside some pretty terrifying mammalian megafauna, so why not dinosaurian? so what would a realistic sapient ape in a dinosaur world be?

it's taken some thinking, but:

wookies.

we'd be wookies.

no need to leave the trees, the grass would be very unsafe if it evolved the same

no need to leave the trees, we remain furry

we could build tree houses and other structures, in the trees, to stay out of the range of predators

that's. just wookies. that's just the wookies.

the Lascaux cave art pins are now live at greerstothers.shop

I’ve loved these for ages, because of how they show the colourations of extinct animals! that’s something that is so hard to preserve through fossils, but now we know that prehistoric horses had Przewalski-esque coats, that giant elk had these dark shoulder humps, and that cave lions were tawny with dorsal stripes

#the book I did (kaleidoscope of dinosaurs) is all about the colourations of extinct animals #and there's a 2-page spread about French cave paintings

[ The skull is mounted on a custom steel armature, which allows for it to be seen all the way around. ]

"After seven years of work, the best preserved and most complete triceratops skull coming from Canada — also known as the "Calli" specimen — is on display for the first time since being found in 2014 at the Royal Tyrrell Museum in Drumheller, Alta. A museum news release calls the specimen "unique" because of where it was discovered, the age of the rock around it, and how well it was preserved. Following the floods that tore through Alberta about 10 years ago, the Royal Tyrrell staff were engaged in flood mitigation paleontology work when the triceratops skull was discovered in 2014. Triceratops fossils are rare in Canada. This skull was found in the foothills of southwestern Alberta — an area where dinosaur fossils in general are uncommon — and nicknamed "Calli" after Callum Creek, the stream where it was discovered. Transported via helicopter in giant, heavy chunks, the skull and most of the jaw pieces were extracted over the course of a month in 2015. The rest of the triceratops' skeleton was not found. Roaming the earth roughly 68 to 69 million years ago, the museum says this skull was buried in stages, evident by the fossilization process. "Paleontologists know this because the specimen was found in different rock layers, and the poorly preserved horn tips suggest they were exposed to additional weathering and erosion," reads a museum blog about the triceratops skull. "The rest of the skeleton likely washed away," noting that the lower jaws were found downstream. From 2016 to 2023, Royal Tyrrell technician Ian Macdonald spent over 6,500 hours preparing this fossil, removing over 815 kilograms of rock that encased the skull. This triceratops skull is the largest skull ever prepared at the museum and its third largest on display."
