Just one of the many reasons why I love geology – paleontologists have unearthed extraordinarily preserved fossils of a 520-million-year-old sea creature, one of the oldest animal fossils ever found. The animal in case is an arthropod called a fuxhianhuiid – you may remember him from this post, in which I described a lovely book […]
Evidence of drowned remnants of an ancient microcontinent have been found in sand grains from the beaches of a small Indian Ocean island, according to a new research. Zircons and volcanoes This evidence was found in Mauritius, a volcanic island 900 kilometres east of Madagascar which serves as an exotic destination for many tourists. Basaltic […]
The longest creatures to ever walk the Earth were the long-necked, long-tailed dinosaurs known as the sauropods. But why did these huge vegetarians grow such huge necks, reaching up to 15 meters? That’s six times longer than that of the current world-record holder, the giraffe. “They were really stupidly, absurdly oversized,” said researcher Michael […]
According to a new study, the generally accepted theory on lunar formation may have to be reexamined. A relatively recent study has found water in the Moon’s original crust, which means that water found in those rocks didn’t come from an outside source, but was already there when the Moon was formed – something impossible, […]
The recent historical flyby of 2012 D14 – the largest asteroid ever to pass this close to Earth in recorded space observational history – as well as the modest in size, but monumental in punch meteorite that exploded over Russia caused an whole frenzy around them on the web. Thing is, meteorites and asteroids have […]
Paleontologists have found evidence of animal life dating back at least 635 million years. Those animals acted much like today’s sponges, stuck in the sea floor, filtering water particles for useful nutrients in the sea. But just over 100 million years later, during the Cambrian explosion, life really started to pump its engines. All sorts […]
The massive, global risk that global warming poses has once again been highlighted by researchers – this time, by geologists studying fossil records. It’s good to learn from your mistakes, but it’s even better to prevent than treat, and learn from the past (even though it’s not your past) – and paleontology is really good […]
Paleontologists have long believed that complex organic molecules couldn’t survive fossilization; but to contradict this long standing belief, some 350-million-year-old remains of aquatic sea creatures uncovered in Ohio, feature exactly that type of molecules. The animals i n case are called crinoids, but are probably better known today as “sea lilies”; they are absolutely […]
While the world was asleep, a few days ago North Korea made its latest nuclear test, the third that we know of. This has prompted intense international pressure on the North Korean regime, as you might imagine, what’s interesting, rather frightening actually, is that seismic activity shows the nukes are getting ever bigger. Pyongyang said […]
A massive earthquake struck Wednesday east of Kira Kira in the Solomon Islands, with several already confirmed victims and injuries. “At 12 minutes past midday, a 7.9 earthquake in the Santa Cruz Islands (near the Solomon Islands) occurred. A shallow event.” He said. “The nearest part from our location estimate is an island called Ndeni, […]
The (still debated) asteroid that slammed into the Earth 65 million years ago and played a crucial role in wiping dinosaurs out, may have actually been a binary system- 2 asteroids engaged in an orbit around each other. Double trouble The surprising claim comes from analyzing the proportion of asteroid craters on Earth that were […]
Ridges of Martian impact craters could be fossils of cracks in the Martian surface, formed by minerals deposited by flowing water, according to a new research. The findings, accepted for publication in Geophysical Research Letters, one of the most prestigious journals in the field, could explain a mysterious network of ridges that vein across the […]
If you think intestinal parasites are a recent problem, you’d better think again. Ancient tapeworm eggs found in 270-million-year-old shark poop suggests these parasites may have plagued animals for much longer than previously believed. Tapeworm are nasty parasites that clink to the walls of the intestines of virtually all vertebrates (animals that have a backbone); […]
A historic expedition that took over 10 years of planning and 3 years of preparation, a national effort from both researchers and students, finally concluded today. The team from Montana State University managed to drill into a lake that has been frozen for hundreds of thousands of years. After hauling equipment hundreds of miles across […]
The general classification splits volcanic eruptions in two: explosive or effusive. An explosive eruption is, well, explosive and violent (think Mount Helens), while an effusive eruption is associated with lava flows (think Hawaii). However, in a new study conducted by New Zealand and UK researchers described another, new type of eruption. Inside volcanoes, magma often […]
The cold, lifeless Vesta asteroid might be a lot more like our planet than astronomers believed – having a very active life in the early stages of the solar system evolution, a study of a Saharan meteorite shows. The planet that wasn’t Vesta might host a magmatic layer under its rocky exterior, allowing minerals to […]
The first sample from underground Mars will come from a rockbed that showcases unexpected mineral veins of gypsum. A Martian candy store Astronomers and geologists are now in the equivalent of a Martian candy store of scientific objectives: the lowest point of Gale crater, called Yellowknife Bay is literally teeming with minerals that could only […]
It should be no surprise for anybody that a major earthquake is way overdue in LA; a study has shown that the area has a 99% chance of a big earthquake in the next 30 years (well, 25 years, since the study was conducted in 2008). Even with what should have been a huge wake […]
Magma forms much deeper than geologists previously believed, according to a new study conducted by Rice University. Magma and Crust The group led by geologist Rajdeep Dasgupta put very small samples of peridotite under very large pressures, to find out if the rock can liquify, at least in small amounts, as deep as 250 […]
A recent study conducted by Californian and Japanese seismologists claims that stable fault areas might not be so stable, in terms of earthquake generation. The controversial findings suggest that creeping fault behavior (more on this in the next paragraph) is actually not only instable, but also capable of creating fast slipping earthquake ruptures. Faulty issues […]
A new species of “sea monster” was unearther in Nevada – a predator so fierce that it often hunted prey as big or bigger than itself. Thalattoarchon saurophagis translates into “lizard-eating sovereign of the sea” – and boy is that a good name. It measured well over 8 meters and lived some 244 million years […]
Deep in Africa, under some of our planet’s most drought threatened areas lie massive water reserves – freshwater aquifers containing 60 times as much water as all the American Great Lakes combined. These aquifers are some 410,000 cubic miles thick and contain 100 times the freshwater that exists on the continent’s surface, and as Africa’s […]
The United States Geological Survey (USGS) reported an undersea earthquake with a magnitude of 6.4 some 142 kilometers off the coast of Baja, California. The earthquake had its origin at approximately 10 km below surface level and so far, no tsunami warning has been issues. Tectonic setting Sitting ontop of three of the large […]
If you want to find out if you’re sitting on a gold mine, you should get some termites, a new experiment conducted in Australia suggests – it concluded that termites “mine” and stockpile the precious metal while they’re collecting subterranean material for their nests. For the study, entomologist Aaron Stewart, with Australia’s Commonwealth Scientific and […]
The mass extinction that wiped out the dinosaurs 65 million years ago also terminated most of the lizards living on our planet at the time – including a newly identified creature that’s been named Obamadon gracilis in honor of President Barack Obama. This is when you know you’ve made it big – when you’ve already […]
As a geologist, I tend to see the Earth as a dynamic setting, with all sorts of processes taking place; however, for me, 100.000 years is a really short period. For other, normal people, over the course of decades and centuries, the Earth is really static, with mountains and valleys seemingly anchored firmly in place. […]
A strong earthquake with an epicenter off the northeastern coast of Japan shook buildings all the way to Tokyo, leading to a tsunami warning for coastal areas of the northeast. The first estimate of the magnitude was 7.4, but was then lowered to 7.3. The United States Geological Survey (USGS) explained there is no risk […]
The Ebb and Flow satellites, known together as the Grail mission are mapping the slight differences in gravity across the Moon. The results show that the Moon received a much bigger battering than previous expected. A troubled past Beneath its surface, the Moon’s interior bears clues from the very early solar system – unlike the […]
Nyasasaurus parringtoni may have not been revered by other dinosaurs, but according to a new study published in Biology Letters, he is the oldest dinosaur to walk the face of the Earth, surpassing the previous record holder by 10-15 million years. It walked on two legs, measured 2-3 m in length, had a large tail […]
Paleodictyon is a mysterious fossil pattern found mainly in marine sediments thought to be specific of a certain paleo-depth range; it is a relatively widespread trace fossil – called this way because it is mainly accepted that it is created by a burrowing creature. Although it has been discovered since the dawn of geology and fossil […]
A study conducted by researchers from the Carnegie Institution for Science concluded that both Earth and Mars got their water from the same source chondritic meteorites. However, unlike Earth, Martian rocks containing atmospheric volatiles such as water don’t get recycled into the planet’s deep interior. The origin, history, and evolution of Martian water are […]
This spike-headed dinosaur roamer a much warmer Canada 78 million years ago, making it the earliest horned reptile ever. “In terms of large-bodied ones that look like Triceratops, this is definitely the oldest,” said biologist Michael Ryan, lead author of the new study describing the dinosaur, published online Thursday by the Canadian Journal of Earth […]
Named after the almost all-powerful dark spirit from the Lord of The Rings, the Sauron dinosaurs roamed Africa some 95 million years ago. The species was named Sauroniops pachytholus, which more or less means “The eye of Sauron”, and it was identified so far from a single fossil found in Morocco. The fossil had only […]
Why would a dinosaur with a body built for running have not two, but four wings, as well as a feathered tail? There seems to be only one real reason: flying. But why would it need to fly in the first place? Paleontologists have long wondered about it, but now it seems, they’ve finally found […]
In a groundbreaking study, researchers at University of Miami (UM) Rosenstiel School of Marine & Atmospheric Science used satellite imagery to study volcanic eruptions from the past years in Indonesia’s west Sunda arc, a highly active volcanic region. Their findings show that images of inflating magma balloons hint towards impending volcanic eruptions in one in two cases, on […]
If you think about tsunamis, you’ll probably think about Japan, Indonesia, maybe America… the last place you’d image would be the Alps, right? Well, you might have to go back to that. About 1500 years ago, a massive flood took place in Geneva, Switzerland, wiping out everything in its path, crippling the local community. Now, […]
Well it may be a bit of overreaction, but with the Halloween and all, you just have to call it: 70 million year old mammal had long, oversized, blood-red teeth, scurrying at the feet of dinosaurs. The discovery of a new skull now gives new insight into his diet and habits. Barbatodon transylvanicus lived in […]
After Curiosity had a bite of Martian turf at the site of Rocknest a few days earlier, soil analysis results have finally come in. According to scientists at NASA, the Martian sand in the rover’s vicinity is very much akin to volcanic soils found on Earth such as those of Hawaii. Though Mars is far from being […]
Scientists in Canada have made a remarkable discovery: they have unearthed the first fossils of a feathered dinosaur ever found in the Americas. Their research, which was published in Science, includes 75 million year old specimens, including a juvenile and two adult ostrich-like creatures which go by the name of ornithomimids. Until now, the only […]
In 2011, a 5.1 magnitude earthquake struck the Spanish city of Lorca, resulting in the loss of 9 lives and the injury of over 100 people. Now, researchers studying the case believe groundwater extraction played a crucial role in triggering this earthquake. A fault is a planar fracture or discontinuity in a volume of rock, across which […]
Remember when, back in May, we told you about a case with a dinosaur skeleton transferred from Mongolia to the US, then auctioned, despite a judge declaring the act illegal? Well… good news! A man from the state of Florida gave an entirely new meaning to ‘grave robbing’ after being lured to the dark side […]
A group of researchers from the United States found out that the Moon is covered with a soil containing typical water structure. Weirdly enough, the water substructure packed soil is created by a constant stream of charged particles coming from the sun, according to the team. The key is hydroxyl. As you probably know, […]
Xenon is a noble gas, the second heaviest of the chemically inert noble gases. The only problem with is that… it’s gone missing! Xenon is almost entirely missing from our atmosphere, somethign which researchers were unable to answer – until now, that is. German researchers believe they managed to find out where the gas is […]
Although Curiosity landed recently on Mars, the rover is already proving its usefulness, beaming back all sort of interesting information; this time, Curiosity has snapped photos of rocky outcroppings which seem to be stream beds where water once flew on the Red Planet. The rock is quite eroded and it consists of rounded gravel consolidated […]
Researchers managed to construct a three dimensional (3D) portrait of two nymphs that inhabited our planet 305 million years ago by scanning their fossils with X-Rays. Old insects At the moment, they are by far the most detailed pictures of juvenile insects that inhabited that period; nymphs are the immature form of some invertebrates, particularly […]
Two studies conducted by scientists at NASA based on data gathered by the Dawn spacecraft, which orbited around the Vesta asteroid, showed that the giant space rock holds tantalizing signs of water on its surface – albeit in very small amounts, in the form of hydrated minerals. These conclusions were drawn after scientists found that volatile, or easily […]
The moment many of us have been waiting for is almost here: Curiosity prepares to make its first contact with a Martian – a Martian rock, that is. The rover has been on the Red Planet for six weeks now, still preparing its devices, namely its Alpha Particle X-Ray Spectrometer (APXS) which will be used […]
In the past couple of months, all Mars-related attention has been almost unanimously shifted towars the Curiosity rover. Not to discredit any of its achievements thus far, which are just appetizers for marvelous fings to come off Curiosity, but the Opportunity rover has been trailing the Martian surface for the past eight years now, long […]
The Japanese scientific deep sea vessel Chikyu managed to set a new world record by drilling down to over 2.200 meters below the seafloor, obtaining samples from Shimokita Peninsula of Japan in the northwest Pacific Ocean. Drilling for science Whenever you hear about drilling, it’s almost always about oil. Given the humongous amount of oil […]
Researchers have found evidence that the crater in case was formed when the ground was slammed by a massive meteorite, millions of years ago. Prince Albert crater Measuring about 25 kilometers across, Prince Albert crater was named after the peninsula in which it was discovered. Researchers never were really sure when it was formed, the […]
