Podcasts about Dickinsonia

Scientists say they have confirmed that strange-looking fossils from more than 500 million years ago are remains of an animal.科学家说，他们已经确认，超过5亿年前的奇怪化石是动物的遗体。That would make it one of the earliest known creatures.那将使它成为最早的已知生物之一。The fossils are found within rocks. They are round with many lines, and look similar to the markings of a leaf.化石在岩石中发现。 它们的圆形有许多线条，看起来与叶子的标记相似。The fossils were first described in 1947. They have been found in Australia and Russia. Some are very small; others are over a meter long.这些化石于1947年首次描述。它们在澳大利亚和俄罗斯发现。 有些很小； 其他人则超过一米。Scientists have named the mysterious ancient organism that left these fossils behind “Dickinsonia.”科学家将神秘的古代有机体命名为，将这些化石留在了“狄金森尼亚”之后。But what exactly was it?但是到底是什么？In the past, some scientists suggested it was an animal. Others believed it was a single-celled organism called a protist.过去，一些科学家认为这是动物。 其他人则认为这是一种称为put虫的单细胞生物。Researchers presented evidence that Dickinsonia was an animal in a recent paper. The paper appeared in the publication Science.研究人员提供了证据，表明狄金森尼亚是最近的一篇论文中的动物。 该论文出现在出版科学中。The most important evidence was that Dickinsonia fossils found in Russia contained carbon-bearing substances produced by animals.最重要的证据是，在俄罗斯发现的狄金尼亚化石中含有动物产生的碳含量。Experts not connected to the study called that evidence strong. They also said most scientists who had studied the fossils already believed that Dickinsonia was probably an animal.与研究没有联系的专家称这证据很强烈。 他们还说，大多数研究化石的科学家已经相信狄金森尼亚可能是动物。Douglas Erwin is with the Smithsonian Institution. He said he is sure the fossils are from an animal.道格拉斯·埃文（Douglas Erwin）与史密森尼机构在一起。 他说，他确定化石来自动物。It is not clear when Dickinsonia lived. Some fossils are about 558 million years old, said Jochen Brocks of the Australian National University in Canberra. He was one of the researchers involved in the study.目前尚不清楚迪金森尼何时居住。 堪培拉澳大利亚国立大学的Jochen Brocks说，一些化石的历史了约5.58亿年。 他是参与研究的研究人员之一。Brocks considers Dickinsonia to be “the very oldest animal that we can be sure about. He added that it is about 2 million years older than another widely accepted animal fossil.布罗克（Brocks）认为狄金森尼亚（Dickinsonia）是“我们可以确定的最古老的动物。他补充说，它比另一种被广泛接受的动物化石大约200万年。Brocks said scientists do not know much about what Dickinsonia looked like. But he said they do know it was “soft and flexible.”布罗克斯说，科学家对狄金森尼的样子不太了解。 但是他说他们确实知道这是“柔软而灵活的”。Dickinsonia was not the first animal on Earth. Analysis of the genetic materials of living animals suggests that animals first appeared more than 720 million years ago. But scientists have never found fossils that old.狄金森尼亚不是地球上的第一只动物。 对活动物的遗传材料的分析表明，动物首先出现在7.2亿年前。 但是科学家从未发现化石那么古老。

In 2020, terwijl de wereld kennismaakte met het leven in lockdowns, werd een groot wetenschapscongres in India afgezegd. Enkele geologen die al ter plekke waren, maakten er het beste van en bezochten de Rotsschuilplaatsen van Bhimbetka.  Ze vonden er een Dickinsonia fossiel: een plat, langwerpig primitief dier dat 550 miljoen jaar geleden leefde, nog voor er complexe dieren bestonden. Het was voor het eerst dat zo'n exemplaar in India werd ontdekt en was groot nieuws.   Nu blijkt het alleen een foutje te zijn. Het gaat namelijk niet om een Dickinsonia fossiel, laat nieuw onderzoek zien, maar om iets heel anders. Toen wetenschappers van de universiteit van Florida vorig jaar afreisden naar India om het object te bekijken, was het een beetje afgebrokkeld. Best gek, voor een fossiel. Ook hingen de overblijfselen verticaal en niet horizontaal, zoals te verwachten was.   Toen ze rond gingen kijken zagen ze in de omgeving nog meer van dezelfde afgebrokkelde constructies aan de rotsen hangen. Het waren geen fossielen, maar bijenkorven. Inmiddels is er ook een reactie van de onderzoekers die de ontdekking in eerste instantie deden. Ze erkennen de fout en sluiten zich aan bij de nieuwe verklaring.   Terwijl één fout is opgehelderd, blijft een ander mysterie staan. De originele vondst hielp namelijk bij het dateren van het gesteente. Nu zijn ze wat dat betreft weer terug bij af. Vermoedelijk zijn de rotsen wel een miljard jaar oud. En dat heeft grote implicaties voor hoe het land in die tijd is gevormd. Het laatste woord is er dus nog niet over gezegd.

I'm your host, Kate Shaw. It's the last week of August 2022, so let's close out invertebrate August with a whole slew of mystery fossils, all invertebrates. But first, we have a birthday shoutout! A humongous happy birthday to Isaac! Whatever your favorite thing is, I hope it happens on your birthday, unless your favorite thing is a kaiju attack. We've talked about the Cambrian explosion before, especially in episode 69 about some of the Burgess shale animals. “Cambrian explosion” is the term for a time starting around 540 million years ago, when diverse and often bizarre-looking animals suddenly appear in the fossil record. But we haven't talked much about what lived before the Cambrian explosion, so let's talk specifically about the Ediacaran (eedee-ACK-eron) biota! I was halfway through researching this episode when I remembered I'd done a Patreon episode about it in 2021. Patrons may recognize that I used part of the Patreon episode in this one. You'd think that would save me time but surprise, it did not. The word Ediacara comes from a range of hills in South Australia, where in 1946 a geologist noticed what he thought were fossilized impressions of jellyfish in the rocks. At the time the rocks were dated to the early Cambrian period, and this was long before the Cambrian explosion was recognized as a thing at all, much less such an important thing. But since then, geologists and paleontologists have reevaluated the hills and determined that they're much older than the Cambrian, dating to between 635 to 539 million years ago. That's as much as 100 million years before the Cambrian. The Ediacaran period was formally designated in 2004 to mark this entire period of time, although fossils of Ediacaran animals generally start appearing about 580 million years ago. Here's something interesting, by the way. During the Ediacaran period, every day was only 22 hours long instead of 24, and there were about 400 days in a year instead of 365. The moon was closer to the earth too. And life on earth was still sorting out the details. Fossils from the Ediacaran period have been discovered in other places besides Australia, including Namibia in southern Africa, Newfoundland in eastern Canada, England, northwestern Russia, and southern China. Once the first well-preserved fossils started being found, in Newfoundland in 1967, paleontologists started to really take notice, because they turned out to be extremely weird. The fossils, not the paleontologists. Many organisms that lived during this time lived on, in, or under microbial mats on the sea floor or at the bottoms of rivers. Microbial mats are colonies of microorganisms like bacteria that grow on surfaces that are either submerged or just tend to stay damp. Microbial mats are still around today, usually growing in extreme environments like hot springs and hypersaline lakes. But 580 million years ago, they were everywhere. One problem with the Ediacaran biota, and I should explain that biota just means all the animals and plants that live in a particular place, is that it's not always clear if a fossil is actually an animal.

A group of geologists touring the Bhimbetka caves at the beginning of the pandemic made an accidental discovery of the oldest fossils ever found in India, belonging to the genus of animals called Dickinsonia, some of the oldest animals to ever exist on Earth. ThePrint’s Sandhya Ramesh explains how these fossils were discovered, what they mean, and what questions still remain.

The episode's main character is a cholesterol-infused blobby mess that never gets enough exercise. It rather prefers to eat scraps off of the floor and leave butt impressions on the filthy bacteria-infested bed it calls home. It also tries to talk about an interesting prehistoric species, but without doing its homework :) ====================== Send us suggestions and comments to darwinsdeviations@gmail.com Intro/outro sampled from "Sequence (Mystery and Terror) 3" by Francisco Sánchez (@fanchisanchez) at pixabay.com Sound effects obtained from https://www.zapsplat.com Image credit Masahiro Miyasaka, CC BY-SA 4.0, via Wikimedia Commons (Episode image is heavily edited, the image owner reserves all rights to their image, and is not affiliated with our podcast) SOURCES: Wikipedia....and all references it already states...the usual

Learn more about the film "Is Genesis History?" and get more resources at http://www.isgenesishistory.com/ The question of how a global Flood could happen is an important area of research for modern creation scientists. One of the theories used to explain this process was developed by a number of scientists featured in the film.* It is known as “Catastrophic Plate Tectonics” and has a great deal of explanatory power concerning the geophysical processes behind the global catastrophe. During the 2017 IGH Conference, Dr. Kurt Wise explored the impact of the global flood on the earth in a series of three in-depth lectures. This lecture on the “geophysics of the flood,” the third in the series, provides a fascinating look at the processes behind the global flood.

The Ediacaran Period is host to the first large and complex multicellular organisms known in the fossil record. This 'Ediacaran Biota' has long eluded definitive placement on the tree of life, seemingly falling between even the most fundamental of its branches. At the core of this taxonomic issue are their unique body plans, not seen replicated in any other kingdom. Amongst the researchers trying to unravel the mystery of these organisms is Dr Frances Dunn of the University of Oxford. Frankie has been researching the developmental biology of the Ediacaran Biota in the hope that we can learn more from how these forms grew, as opposed to what they eventually grew into.

Los fósiles de Dickinsonia son moldes en lechos de arenisca. Miden entre unos milímetros y casi metro y medio de largo, con un espesor de entre una fracción de milímetro y unos pocos milímetros. Su cuerpo ovalado, que carece de boca y de ano, tiene un extremo más ancho que el otro. Dickinsonia se ha interpretado como una medusa, un coral, un gusano poliqueto, una planaria, una anémona, un cordado o incluso un hongo, un líquen o un organismo unicelular gigante. Dos descubrimientos recientes apuntan a que Dickinsonia era un animal. Los primeros fósiles de Dickinsonia se descubrieron en los montes Flinders, en Australia Meridional, en 1947. El geólogo australiano Reginald Sprigg les dio el nombre de Dickinsonia en honor de su jefe, Ben Dickinson, director de minas de Australia Meridional.

The gang discusses two papers that use new findings to upend some of our previous interpretations of fossil taxa. First, they talk about the new biogeochemical studies that suggest the odd disc-shaped Ediacaran organism, Dickinsonia, might be the first animal in our fossil record. Second, they talk about some new fossil interpretations that challenge our understanding about the evolution of sauropods (the big, long necked dinosaurs). Also, James discusses posture, Curt buries the dinosaur lede, and Amanda finds out she has things to say… later.   Up-Goer Five (Curt Edition): The friends get together to talk about new things that have been found out about some very old things. First, they talk about this round thing that was around a very very very long time ago. This round thing was very funny looking, and a lot of people had different ideas about what this round thing could have been. But some people just did a study to try and found out what the round thing was made of. It turns out, the round thing is made up of matter with 4 bits in rings. These types of matter rings are only found today in all of the animals. So, they then said that this funny looking round thing was probably an animal. The friends next talk about these very large animals that had very long necks and lived a long time ago. These long necked animals were thought to have gotten really big after they started walking on all four of their feet and their legs became like trees. However, this study found that there were earlier long necked animals that were almost just as big, but were able to spend some time on two feet and their legs were still very much like legs. This means that these long necked animals got big and got small again over time without needing to get really thick tree legs that would make them have to only walk on four feet.   References: Bobrovskiy, Ilya, et al.

What were the earliest animals on Earth? The origin of the animal kingdom is one of the most mysterious chapters in the evolution of life on Earth. Our animal ancestors appeared and began to diversify about half a billion years ago. What might they have looked like, and which creatures alive today can be traced to these primordial times? Answers are beginning to come with new techniques for both studying ancient fossils and for reading evolutionary history from the DNA of animals alive today. Zoologist Professor Matthew Cobb explores the latest discoveries and controversies with the researchers on the trail of the Earth’s first animals.
