The 10 Oldest Fossils Ever Discovered

[@robertgoldsworthy5481]

I love how humble this channel is... it’s refreshing

[@johnstewart8849]

I found a beautiful stromatolite fossil on a hill in Wyoming, which was once an ocean. My fascination is the first amphibians, and the transition in eggs: wet, internal, dry that give them freedom from the sea. I have also read that the ginkgo was one of the earliest trees (200M), and was believed extinct until 1100, when examples were found in Buddhist monasteries.The ginkgo leaf veins radiate from the stem, while most leaves we see are branching.

[@JLin943]

I’ve accumulated an extensive collection of both personal finds and bought fossils, some very rare and pretty expensive, but my favorite is still my examples of stromatolites. It’s not the rarest of fossils, but there’s just something special about holding a once-living piece of prehistory and knowing that it’s over 3 billion years old. It’s crazy to think that such simple organisms like that diversified into hundreds of millions of various complex organisms.

[@JLin943]

It’s also crazy to think that, while sparsely distributed, living stromatolites still exist 3.5 billion years later.

[@glendapeterson1180]

@@samuelswanepoel7926 But Carbon dating is only ONE method of dating. We do not only use the Carbon dating method... www.smithsonianmag.com/smithsonian-institution/how-do-scientists-date-fossils-180972391/ Together with stratigraphic principles, radiometric dating methods are used in geochronology to establish the geologic time scale.[3] Among the best-known techniques are radiocarbon dating, potassium-argon dating and uranium-lead dating. By allowing the establishment of geological timescales, it provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change. Radiometric dating is also used to date archaeological materials, including ancient artifacts. Different methods of radiometric dating vary in the timescale over which they are accurate and the materials to which they can be applied. Then there is Luminescence dating (including thermoluminescence and optically stimulated luminescence) - a type of dating methodology that measures the amount of light emitted from energy stored in certain rock types and derived soils to obtain an absolute date for a specific event that occurred in the past. The method is a direct dating technique, meaning that the amount of energy emitted is a direct result of the event being measured. Better still, unlike radiocarbon dating, the effect luminescence dating measures increases with time. www.thoughtco.com/luminescence-dating-cosmic-method-171538 New developments in laser ablation mass spectrometry permit the in situ analysis of U-series isotopes, thus providing a rapid and virtually non-destructive dating method back to about 300,000 years. For those highly funded scientists like Svante Paabo there is also Accelerator Mass Spectrometry available...as used on his Neanderthal research. www.radiocarbon.com/accelerator-mass-spectrometry.htm

Foghorn Leghorn yes but that's only a crystal. Obviously zircon are the oldest possible crystal. A rock (such as a gneiss) is an aggregation of crystals. The zircon in this rock is older than the rest of the parts the article even says "The Australian zircons, from the Jack Hills, aren't the oldest rocks on Earth - those are in Canada - but about 3 billion years ago, the minerals eroded out some of Earth's first continental crust and became part of a riverbed."

They only do so on film and it's because of the recording speed. A typical camera only records 24 images per second. If a wheel spins faster than one 1 round per 1/24th of a second, it will apear to go backwards. The problem is easily solved by buying a highspeed camera and a tv with a high refresh rate

In all seriousness, this is one of the best and informative channels on KZbin, and I love every video they put out. I had no idea that there were fossils older than 4 billion years. That's mind blowing, considering the earth is 4.5 billion years old.

Actually, I've seen about fifteen Obnoxious creationists in the comment section.

I'm not an atheist but i still hate creationists

@@vladislavdracula1763 I've seen non. I've seen religious people & heck I'm religious but no creationists.

I thought "juramaia" was a bullfrog

[@SweetGambit]

Um, no fungus? Gondwanagaricites magnificus? Fungus are essentially the only reason that plants survived extinction. Or, maybe the mycelium found to be almost BILLIONS of years old?

[@excommunicatus-1547]

Bah - Juramaia couldn't have been the earliest mammal. Juramaia was a bullfrog. Was a good friend of mine.

This is why I prefer zerg and pokemon. Evolution is a simple matter with them. XD

[@smurfyday]

Rakshasa Simple things for simple minds.

[@FreedomAnderson]

Pokémon evolution is an exaggerated form of metamorphosis.

The video is hampered by the ambiguity in the term "fossil". For example, a stromatolite is the oldest VISIBLE fossil, sure--but it's not the oldest BODY fossil (stromatolites are strictly speaking trace fossils because no part of the bacterial mat is preserved). It makes discussing this sort of thing rather difficult, and leads to heated debates in bars that lead to being thrown out of said bars. :D The Small Shelly Fauna (SSF) predates the Cambrian, and demonstrate that in at least some lineages (the ancestors of velvet worms, for example) mineralized parts originated as small patches--meaning we probably have fossils of earlier arthropods, chordates, and other critters, we just haven't been able to determine it yet. If you want to give yourself a migraine, look into the math of phylogeny. By definition, the first of any clade (any group of animals that's "real" in biology) is necessarily more similar to things outside the clade than those inside it. Think of it this way: Your great-great-great-great grandfather looked more like your great-great-great-great-great grandfather than he looked like you. This leads to serious difficulties in trying to figure out how to classify things in a system where the classification is "an ancestor and all its descendents". An example of this is birds--the first bird is more similar to non-bird dinosaurs than to modern birds, meaning it is hidden among those non-bird dinosaurs. The other problem is "What is a clade?" There's something called a paraphyletic group, which means "An ancestor and SOME of its descendants". It sounds complicated, but is actually fairly simple. When someone says "apes" you know they're not talking about humans, unless they specify that they are. Strictly speaking, that's wrong--humans are, strictly speaking, apes. But it makes sense to talk about apes as different because humans are fairly unique. Similarly, strictly speaking "reptile" includes mammals, squamates, turtles, snakes, and pretty much all other amniots--because we all descended from a common ancestor. But it makes much more sense to talk about reptiles, mammals, turtles, and snakes. All of this means that defining what the group you're looking for the first ancestor OF is tricky! Then there's the fact that the FAD (first appearance datum) is not likely to be the first appearance, which opens up a whole OTHER can of worms, involving statistics and stratigraphy. I've frequently said that paleontology is one of the hardest things for a human to wrap their mind around. This is just the start of the complexities involved--and yet we have been able to define the history of life in detail that would astound anyone not intimately familiar with the literature. It's a field where we are routinely asked to reconstruct a whole ecosystem from a few scraps of bone and dirt AND WE DO! I truly love this field of study!

[@karlosjeffers4791]

Animal Classification and Speciation is just a human construct to help us articulate the differences we see between animals and plants. The Paradoxical thing is that, even though over time species evolve away from each other to become separate species; every living thing that ever existed was the exact same species as it's parent, and it's offspring.

Are there any specific reason that you all have to speak so fast. Otherwise very informative video as always.
