Hi I presume you are a geologist, explanation is great. Right now we are planning a large drilling campaign in the border area of Belgium, Netherlands and Germany. This is done to make a detailed 3D-map of this area for the Einstein Telescope (huge subsurface gravitational wave observatory to study colliding stars, black holes et cetera) We already drilled three times to the contact between the late Devonian (Famennian) and Carboniferous, but in those cases with a large hiatus in geology 324 MYr jumped to 360 MYr. We also saw interesting layering in the Famennian stage 370-360 Myr, we just didn't reach 359,2 MYr yet which was the End of the Devonian age. But we will also drill Frasnian age layers which was the first pulse. There might even be 3 pulses that could be found in those stages. KR Bjorn

Fascinating, thank you.

I was surprised to find that so much of the gneiss in New England was actually an accumulation of volcanic ash from the Ordovician. When you consider the benefits that volcanic ash has on a resurgence of plant life, I wonder what is more important in the production of soil? Having glaciers grinding down some of the relief like a giant sheet of sandpaper was probably more effective than waiting for weak acids to crumble near insoluble rocks. I have to wonder what the slow evolution of mulch had on determining what food plants would evolve and sustain large herbivores. The Ammonoosuc Volcanics were part of a huge mountain system and it is hard to believe that chemical means alone would shrink the Appalachians to their present size.

Very interesting, great summary!

Amazing video and so much interesting content that not only puts what the current theory is, which I've found many channels that might put out scientific information, but issues with the theory, and potential, though unyet proven theories to get around them (this is how things should be, it's good science works, it's an ever changing field with new discoveries being made all the time).

Didn't Gondwanaland drift fairly close to the South Pole during this period, giving massive glaciers a perch to build and spread out from? I recall reading somewhere that this might have contributed to the extreme glaciation event that happened at the end of this period. If there hadn't been so much land that close to the South Pole, the glaciers couldn't have been as extensive. Something similar may have contributed to our more recent Ice Age, which I guess technically we're still in. A bunch of land (Antarctica) is available at the South Pole for glaciers to build up on, glaciers that would otherwise be incapable of forming in the open ocean. There's also quite a lot of land - Canada, Russia, Northern Europe, Alaska, Greenland - clustered fairly near the North Pole, meaning that once the climate cools sufficiently, massive glaciers can form in the Northern Hemisphere as well. Without Antarctica, and if the continents more closely hugged the equator, it would be far more difficult for an Ice Age to develop and persist.

Yep, this actually happened just before the Devonian in the late Ordovician (so it was actually the cause for the Ordovician extinctions, which I talk about in that video: kzread.info/dash/bejne/doN4vNFxdcqyl5s.html). I think it contributed to the Devonian glaciation, but it wasn't the main driver for the onset of climate change since it was already positioned theres. And you are also right about the modern ice age, as soon as continental landmasses became isolated near the poles, cooling of the poles greatly increased because the waters circulated around just the poles getting colder and colder. Before Antarctica was isolated at the S pole, when Austrailia, India, and S America were still attached, it remained relatively warm because the water was too warm since it's circulation pattern was different, I actually talk about this in another video if you want to check it out: kzread.info/dash/bejne/kYqk3KayfrzFp6w.html haha sorry to throw so many videos at you, I just feel as though you are mentioning exactly the things I cover in those, so you may be interested :) Also you sound like the kind of person I should have watch those videos because you may be able to provide more insight into the processes or even correct something I say :) Anyway, thanks for the comment! ;D

Hi Geo Girl :) May I ask what is your background? For someone who appears to be so young, you have a lot of knowledge. Do you have a degree(s)? If so, where from? Until he went off to college, we had a young man at the NHSM, who was that way too. Besides working with fossils, I also do my best to keep up with the ongoing research on extinction and climate events, which often seen to be related: The importance being that after extinction events, there’s a burst of evolution to fill various niches. What I especially like about this presentation, is that you explain all the potential causes of the Late Devonian Extinction. Even though people might favor one cause over another, I feel that it’s important to be aware of all possibilities. I say that in part because so much of what we thought we knew about Earth’s past in the 1950-60s, has changed. I’ve felt for a number of years that concerning Historical Geology, we are living in a golden age of discovery: in part due to the advent of computers, and also the development of new equipment and techniques that allow us to see more detail in the geologic record then ever before.

Thanks, seems that a combination of factors contributed to the Devonian Extinction. The mysteries of whether or not a gamma ray burster contributed to it would require first proving the burster occurred and then calculating timescales in relation to computer models of how long fauna and flora had to adapt through evolution of multiple generations. If a burster occurred when the dramatic increase in plant sizes from several feet tall to 70 feet tall and to when the plants expanded due to seeds into previously barren areas. Then there may have been a slow enough transition for 70 percent (arbitrary thought experiment amount) of the faunal species to go extinct, but the addition of a Gamma Ray burster increased it to 90 percent for example. Seems these major changes would be sufficient to cause extinction without the Hypernova but the hypernova is such an interesting idea that simple proving that it left its mark on our planet is intriguing,

Talking about the Devonian it would be nice if they could bring back the Eusthenopteron.

@@JasonKale What a great question! Trust me, your thoughts make complete sense, I wondered this for a long time too! The glaciers actually do grow from snow because warm air from the equator migrates to the poles where it then cools down and sinks and eventually falls to the ground as snow. The snow is then compacted into something called 'fern' then it eventually becomes solid ice and the friction at the bottom of the ice sheet or glacier creates heat which allows some water to melt and the glacier to move (although these are all VERY slow processes). I actually havea video about glacial environments and I talk in it about how glaciers form if you're interested: kzread.info/dash/bejne/Y6um0alric6ygtI.html ;) You are right, however, that as a whole the globe becomes a lot drier during ice ages and glaciations and its just because the cooler oceans undergo less evaporation than when the globe is warmer, and less evaporation also means less precipitation. During some intense glacial periods ice sheets can form by the ocean directly freezing. It is only continental ice sheets and glaciers that require snow. Anyway, hope that makes a bit more sense! And hope you enjoy the glacier video ;)

Yet another great video. I liked the explanation of how weathering can lead to changes in the ecosystem and climate.

I've heard that the development of wood as a material contributed to the devonian extinction as well, since nothing had yet evolved to break it down, woody plants became a massive carbon sink. Have you seen anything relating to this hypothesis? I find it interesting as an example of how nature adapts to break down complex materials, and how that might relate to the current plastic crisis. If there's more plastic in the ocean than fish biomass, something will eventually come along and learn how to break it down.

BTW: The german Wikipedia names the Woodleigh impact crater in Australia as one possible cause for the extinction as it was of the right age (364 mya +/- 8 mya) and still a bit smaller than the asteroid from the K-PG boundary but not by much. What do you think?

Excellent palaeo show! Engaging and rich in scientific info. BTW low CO2 can cause ocean anoxia in another way (other than eutrophication from soils).

Yes! This is a very important point. I think a lot of people assume the chemical reservoirs for the major elements (the atmosphere, hydrosphere, geosphere, etc) are all in equilibrium all the time, but earth is characteristically out of equilibrium all th e time which drives these differences and also creates the energy for life! :) So yes, absolutely the deep oceans and the atmosphere are not always in perfect balance (in fact, most often in earth's history they've been completely out of balance with the deep ocean containing a lack of oxygen; only recently on modern earth have the oceans been relatively fully oxygenated). :)

I never did trust those trees. Interesting how many rocks are named after Celtic British tribes, Ordovices, Silures, Dumnoni (Devon derives it’s name from them). Ironic that they were Iron Age not Stone Age.

Super nova explosion in a nearby solar system. That's all it took for me.

The uv damage along with that cooling might make sense if a volcanic eruption or impact sent large amounts of both sulfur dioxide and some chlorine compound into the stratosphere at the same time. As I recall it's the chlorine in CFCs that damaged the ozone layer.

Hi! Are there any geological markers for a massive volcanic eruption event? Obviously, lava flows of the correct age, but I mean any chemical markers of a massive release of sulfur-based materials into the atmosphere? I'm just wondering if there's a way to gather that kind of evidence. Edited: LOL, at 7am I can barely put thoughts together. I'm talking about maybe rock layers or something like BIFs.

Would Cooksonia be one of the earliest vascular plants?

Was the organic/nitrogen-rich runoff into the oceans during the Devonian period greater than that which occurs today? I would have thought that current runoff would be greater, since the rocks and soil are presumably even more broken down that they were during the Devonian, as well as man-made nitrogen run-off.

Hii geo girl...

Using the axiom 'The present is the key to the past', and while not always true is a good starting point, do we currently see the extinction (or reduction) of near shore marine life in those areas of the globe with high levels of forest or plant cover near those coasts? For example, Southeast Asia, the Philippines, Indonesia, Central America, Central Africa, etc? Are those areas anoxic? I think large silt loads would adversely affect life near shore, but silt loads should go down as plant life and soil stabilization go up, the riparian buffer effect.

@GEOGIRL

Absolutely. Areas where there is a lot of nutrient influx (such as where the Mississippi enters the Gulf of Mexico) there are algal blooms at the waters surface that cause the bottom waters to become anoxic. The common term for modern ocean anoxic zones is 'dead zones' so if you look up map of dead zones, you'll be able to see where these current anoxic zones are in are ocean today. They're very concentrated at continental margins because that's where the influx of nutrients that feeds the blooms comes in. Hope that answers your question :)

Жыл бұрын

Hi! Supernovae occur when stars around 8-10+ solar masses run out of fuel in their iron core. These higher mass stars are much less common than lower mass stars like our sun & their lives are much shorter. There's a lower likelihood of a higher mass star being in your backyard (especially in our section of the galaxy since we're kind of far from many of the star forming regions), so there's a lower likelihood of a supernova explosion in your backyard. The solar system formed in a star forming region of some sort around 4.5-5 Gya, so higher mass stars in that region died ages ago, so we're not really near (astronomically speaking) anything that's likely to go kablooey anytime soon. Thank goodness. 😬 However, a lower chance isn't a non-zero chance, so there's a possibility that a supernova could be implicated in one or more of Earth's past extinction events. There's a far smaller chance of Earth getting hit by an asteroid now than 3.5-4 Gya, but it can still happen.

Well done, but permit me to raise my hand for a question. The process of building soil would have taken millions of years, and ocean microorganisms would have had plenty of time to adapt to a more nutrient dense environment. Also, more land plants means more oxygen (witness the carboniferous), again on a scale of millions of years. I would expect animals to thrive, not die off. Microorganisms are at the bottom of the food chain after all. And we can easily observe that the animals requiring oxygen had no issues shortly after the extinction event. Sudden change causes extinctions, not gradual change. Organisms do not have time to adapt. A few lucky ones find themselves in enclaves where they eek their way through the event. So where is the sudden change, defined as less than 100,000 years? Extra-solar events - supernova, gamma ray burst, dense cloud, etc. - fits the data without a smoking gun. A supernova might leave isotope traces like plutonium, although I am not aware of any such traces, but a gamma ray burst would not. The vulcanism theory should mirror the Carboniferous extinction, which did not produce an ice age during or immediately after the event. If you agree with this reasoning, that only some sudden change could produce a mass extinction, what is your next best bet?

We typically preface it with the isotope system in question, for example when the excursion occurs in the C isotope record we call it a carbon isotope excursion, and so on for the other systems.

Why was the equatorial region more efected. Wouldn't ionizing radiation coming from the sun be strongest at the equator. What do you suppose the effect would be if a very very large body hit the sun . Let's say like a Jupiter sized planet. The majority of stars we see in the night sky have Jupiter sized and bigger planets orbiting very close to their sun. The mass of our sun is about 99 3/4 the mass of the solar system. Loosing a Jupiter might not be a big deal. Or maybe it could temporarily cause the surface of or sun to giggle like jello. Long enough to overwhelm the ozone layer. Killing most of the equatorial life. The second devotion extinction maybe cause be what ever knocked the rest of the planet off mercury. Or maybe another big inner planet fell victim the the disturbance of the first event. Now all we have to figure out is why all this solar destruction this late in the game. Then again, who knows how many extinction we would have counted if multicellular life had started a billion years ago. I guess what puzzles me is the equatorial region getting hit the hardest. Seems like something came from the sun. Anyway I loved your video. 😊

Why did the Y chromosomes of Neanderthals/Denisovans come out to be so similar between them and us? Let's take a look. When they make statements of Neanderthal DNA vs. human DNA in their comparisons, it is misdirection. In actuality, it is common gene expression between us. Neanderthals WERE human with mere gene expression modification differences with NO implied evolving of DNA mutations being involved. It's sleight of hand. Actual tabulation of our DNA sequences with theirs showed a result of 99.84% commonality. We are 99.90% identical to each other. Why the 00.10% difference between each human being? It's mutation load. Why the 00.06% difference between us and them? Again...its the mutation load accumulation over the thousands of years since we co-existed. Subtract the thousands of years, then we would be 99.9% identical All this is evolution-impertinent. What is pertinent about the disseminators of evolution information and the resulting confused public who selects to listen to them? It shows misdirection and propagandization. It's control of the information to make a false impression of 'evolving DNA mutations'...general evolution to the fans of evolution. The problem? Genes modify by chemical tagging, largely by methylation, ABOVE the DNA sequences without mutations to them. It's a 2nd information code called the 'epigenome'. Purveyors of evolutionary theory makes it seem there is only ONE information code, being the DNA code. It's lying by simplifying, accidentally for many who only memorized what their professors wanted for a passing grade, and pass on this misdirection to others. For a pretty good paycheck, too. Want to know another misdirection? It's implying that chimpanzee's DNA sequence 'similarity' to humans of '98.5%' would be from the same scientific method applications as the 99.84% Neanderthal-human similarity. Is it? No. The chimpanzee comparison is between similar genes while EXCLUDING the non-coding DNA regions. With the Neanderthals, it's comparing ALL of the DNA sequence. Not ending there, the chimpanzee's Y chromosome in the sex-specific regions was compared to us, the pro-evolution researcher was surprised to find they were missing 33% of the total human genes. He said the difference was 'horrendous'! He said the difference between us and them was as large as the difference between a chicken's Y chromosome and ours. So how TODAY'S male chimp offspring be 98.5% similar to human's male offspring when 33% of the genes are missing? The scientific prediction before the study was done, the two Y chromosomes should have been 98%+ similar. What was their rescue excuse to this intelligent design-friendly finding? What is the rescue excuse for just looking at a fraction of the chimp DNA, not the entire sequence, for the 98.5% similarity? Why imply just DNA in Neanderthal comparisons when it's common gene expression instead? It looks like a degree in evolutionary biology and theory is made of misdirection and memorization of rescue excuses. 'Evolution' is misrepresentation of gene expression, epigenetics, and the epigenome's capabilities and claims of gene degeneration causes evolutionary generation. What is the root of this claim of degeneration leading to generation? It is in the above sentence! it's taking these epigenome-derived gene expression capabilities and THE ASSUMPTION OF EVOLVING DNA MUTATIONS when...by definition...no mutations happen with this biological system. What else does this epigenome's capability do? It makes adaptations to changed environment, diet, or new threats for hundreds of generations, if needed. It can do it for one or two generations if the change switches back. This includes the Darwin Finch beaks WITHOUT the theorized 'engine' of evolution. This is a post-2014 new-info THIRD ASPECT of epigenetic ability. Thusly, it is an intelligent design signature by its logistics and common sense when no bias is applied. The science-specific information above is web search retrievable and verifiable. Why does people like me have more scientific information than the innocent consumers of the evolution theory do? It is because the evolution-unfriendly information is withheld or piecemealed. It shows propagandization, not rationalization. It shows people like me gets the truth demonstrated while others take it dictated by their mentors they selected to listen to. There you go. There's your science. Evolution is not happening. We are a creation. The creator? Jesus Christ beyond doubt. I have put decades of research in this truth demonstrated to me. The 'dots of the picture' that the theory of evolution gives is the illusion of there being no God. It produces a much higher suicide rate in kids raised in this fatalism. The accompanying depression is not good in trying to foster a successful civilization to pass on to our children. The 'science' of evolution disrupts the sciences of other applications of science such as in psychology and social science aspects. It has selfish political science benefits to those who push the theory.
