I watch and listen to you during my lunch hour, and I learn so much. This brings back memories of trying to rewind those compact cassettes with a pencil! lol...Thank you!
I came to your channel because I wanted to learn more about my first fossil. Thanks to your videos I was able to learn about the deposition and transport of sediments and how to read the terrain and GIS mapping of my surroundings and finds. Thank you
My mirrored fossil actually used a beard trimmer this morning... I kid you not. It was so real it looked like I could touch it, but it was only to look at. Darn thing almost didn't have any hair
great timing. I am on week 2 of my intro to paleontology unit and have a timed quiz coming up in a few days. I haven't really been finding paleontology very interesting at all but have to do it as part of my geoscience degree. Funny because watching JP as a kid made me want to be a paleontologist. Perhaps this video will stir up some interest. Thanks Shawn
Many thanks, Shawn, for another informative video. I am learning how the separate subjects I've thought about before, rocks, landscapes and fossils all fit together and help each other tell the story of the Earth and life on our planet.
Laser disks, haha. I remember seeing those in grade school. Whenever the teacher brought out the laser disks, it was always a good time. Index Fossils, very interesting.
I am a people watcher, so a few years ago when the instructor passed around a coprolite in a geology class I took it was fun to watch the expressions on people’s faces when they were told what it was that they had been handling. The woman that was holding it dropped it.
If I poop near enough rivers, at least one of those might still be around in a million years. As for pop culture index fossils, the one thing I can think of that appeared suddenly, was everywhere suddenly, and then pretty much dropped of the face of the earth within less than a decade is.....the Rubik's cube. It can usually be found in the same landfill layer as Atari 2600s, Member's Only jackets, and other also-ran mechanical puzzles.
At my house, the Rubik's Cube is alive and well. My kids each had their stint with it over the past decade and they still sell them at toy stores. The Member's Only jackets is a good example though.
Thank you Shawn for this educational, easy to understand and entertaining episode :) I didn't realize that all the fossils represent less than 1% of all organisms that have ever existed, this is amazing... As for inanimate objects (and hairstyles ;) I'd never thought of them as index fossils but, yes, it makes total sense!
Your list of fossils, is a little short. I learned about Shawn Wilsey from his contributions to Nick's channel. Believe it or not, sometimes we can learn about ancient life and conditions it lived under from plant fossils. There are practical uses for learning geology. I am a former UW and CWU student, we studied the ecology of Miocene sediments with the help of fossils of leaves. There was a Quonset hut, (during WWII CWSC trained bomber pilots), with plywood tables of shale collected from the Yakima Canyon. Students were encouraged, with hammer and chisel, to try their hand at revealing leaf fossils. Understanding that the leaves preserved as fossils were largely riparian, heavy on poplars and alders, we could search for more determinate leaves from upland. The odd palm frond was a trophy. The best revealed fossils were put on display in the Biology building. Many maple, deciduous oak, live oak, hickory, sycamore, finds show that the region was forested, similar to the modern Appalachians, with a summer rainfall climate, around 40 inches a year. The palm frond and live oak species, tells us that freezing temperatures were rare, more like Georgia than New Hampshire or Maine.
My fossil story==,,recently,at a job cleaning,moving,,...they had a old box of petrified wood pieces,,...so I dug through them,,,and one had a woodpecker hole in it(truth),,,I know pileated,downy woodpecker excavation in wood,,,...and this was a "for sure" hole by an ancient bird peckings,,....so cool,,I had to tell you!!!,tnx,pat,..land o' lakes,wi.
This is off this subject but what do you know about the earthquake off the coast of Oregon near coos bay? But this was a good video too. All your videos are interesting and informative.
Hi Shawn, Love your work. Have you considered the "Universal Model" by Dean W. Sessions ? He suggested that most of the dinosaurs and petrified wood fossils were formed by a universal flood.
If there was a global flood, where would all the water go? And where did it all start? It would have to move from high elevation to low elevation due to gravity. If there was a global flood, why don't we find the dinosaur fossils mixed with camels, trilobites, coral, and other organisms?
@@shawnwillsey According to Sessions theory, the water came out of the earth, then went back into the earth where it resides now. Most science theories today, presume that the earth harbors magma, looking for a place to escape (Volcanoes), however no one has ever seen magma. The igneous rock called lava, when hot , is formed by earths plates and fault lines rubbing together and creating enough heat to form lava. Each day the earth experiences "Earth Tides" that create the movement to cause the heat. Recent discoveries by China reveal's that the earth has much more water in it, than on it. Many craters found today, are believed to be "hydro craters" rather than impact craters, and an example of a hydro fountain, would be those rock formations that just seem to jet straight up out of the earth. As far as camels mixed with dinosaurs , I don't know , however I will keep my eyes open and let you know if I fined anything. I am not trying to argue, but learn. This stuff fascinates me, and your pictures, and on the scene reporting takes me where I am unable to go, I am 77 and just can't make it out anymore. Thank You and keep up the exploring.
Can you please go a little more in-depth at some point with an example of what conditions were actually needed to create a fossil. Love this segment, BTW.
I already had questions lined up before watching the video! When you get to fossils, does that straddle archeology or it is still wholly within geology's realm? Do you guys find a fossil and hand it over to acheologist for identification/age? or do you take enough acheology lessons to be able to do that yourselves? At what point in a dig, do you decided it is too important a find and you need archeologists involved? (eg: large field full of dinosaur bones).
How does carbon based life form get preserved long enough to become part of rock? You only mentioned low energy environment, but won't they body decay and become "dust" well before the sediment around it becomes a rock under pressure/heat? Does this require total lack of oxygen to prevent decay? You mentioned trilobytes. But what about vast forests that magically became oil fields? What happened in Texas or Saudi Arabia or Alberta to cause vast amounts of biological material to get burried so deep, so quickly that pressure transformed the decaying material into oil instead of mulch? Giant meteorite fell on area to instantly cover it? Since geology tends to measure time in Ma, but carbon life decays in a couple of years, I am curious on if fossilisation requires some sort of cataclysmic event to "freeze" life forms to reduce decay for very long time until the sand in which they are burried becomes a rock? Or is it a case of sand turning to rock overnight ? (and again, what sort of events would result in a crab burried in sand on a beach to become crab fossilised in rock overnight ?
The massive amounts of coal from the Carboniferous are mostly derived from lignin (basically wood), and it's hypothesized that at this time hadn't yet evolved the capability to metabolize lignin, which lead to the huge deposits from that era.
You've piled in a bunch of questions that sound like the type that comes from listening to creationist propaganda. Anyway, there are answers to all of your questions, but the important thing for you is to identify the presuppositions with which you load each question.
I have both a Cassette player and two laser disk machines with about 15 TV StarTrek shows and other movies. I guess a Commodore 64 isn't a good choice along with a TI desk computer.
In terms of the poop, is this a case of poop that was coated with sand that became part of sandstone? If you were to cut the poop on half, what would the middle of it contain? Is this a case of the poop being cooked by hot rocks to a point where all water evaporated and all bacteria killed so it would not decay?
A question please. When less than 1 percent of orginisms were fossilized and found is that less than one percent of individuals or one percent of species?
In my very amateur opinion, the tooth is from a mammoth and not a mastodon, as it looks more like an elephant tooth with its lamellae (elephants are much closer to mammoths than to mastodons). Mastodons teeth are rather pointy ("nipple-teeeth", as their name translates to)

There are also casts of tree trunks or roots in solidified lava. New ones are being created in our modern era in Hawaii for example.
A question which has always puzzled me: If fish evolved into amphibians, why do we still have fish?
Thank you, I am learning so much from you I didn't learned in school. Got to keep this 78 year old brain working and learning.
I watch and listen to you during my lunch hour, and I learn so much. This brings back memories of trying to rewind those compact cassettes with a pencil! lol...Thank you!
Really informative. I love finding old mix tapes by those ancient humans. Disco was an index fossil. Ty
Yay! I finally passed a quiz 😂 Thank you. This was really interesting.
We got perfect scores!
I got the quiz question too! These classes are so helpful...thank you, Professor!😊
I came to your channel because I wanted to learn more about my first fossil. Thanks to your videos I was able to learn about the deposition and transport of sediments and how to read the terrain and GIS mapping of my surroundings and finds. Thank you
Shawn, please explain the Body Fossil I saw this morning in my bathroom mirror.
My mirrored fossil actually used a beard trimmer this morning... I kid you not. It was so real it looked like I could touch it, but it was only to look at. Darn thing almost didn't have any hair
@@paulowens1715 🤣I see the same fossil in my mirror.
I'm mid fossilization.... So maybe we need to compare🤔😅
My mirror showed a fossil crawling out of my bed!!😳😂😂 lots of cracking sounds accompanied the movement!
I see a dinosaur every day.
Thank you Shawn. I learned a lot about fossils and I enjoyed your pop quiz.
Thanks Shawn, amazing as usual and very plain language, very helpful. T-rocks 😎

I think of this as Mother Nature showing off at what she can do 😮. Amazing stuff.

For me, the word 'fossil' brings to mind the seashell fossils I used to collect when I lived in central Texas.
Thank you Shawn for this educational, easy to understand and entertaining episode :)

Thanks for all the hard work on these videos!
Another great presentation! Thanks!
Thanks!
Thank you for your kind donation to support these videos.
You make learning fun professor. I thought aw fossils, this is going to be boooring. SO NOT TRUE! Even liked the quiz
question at the end!
I enjoyed this and learned a lot. Thanks--
Thank you.
Thank you for these videos , i love them .
Great video. I'd be interested in learning more about micro fossils.
Thank you very informative love these
So funny I was just walking in the Boise foothills through the old lake sediments. Wondering why there isn't more fish fossils?

The story of the discovery of the Ediacaran fossils in England by some adolescents is very interesting.
Another very informative video. Will there be a Geology 102 for the spring semester? I'll contribute.

Enjoyed the class and quiz! Can they cut a coprolite to see if any identifiable food materials are inside? Is any of that preserved?
I think they can but it is somewhat rare.
Bedankt
23:35. LOL 'teased hair.' Looks more like traumatized hair to me.

It's archaeology if humans are involved, otherwise it's geology/paleontology.

Thanks!
Peat bogs are another good place to find fossils
A question please. When less than 1 percent of orginisms were fossilized and found is that less than one percent of individuals or one percent of species?
Too bad you did not mention amber.... It has such incredible deails...
Also is an imprint of a fish (not the actual body remains) more of a trace fossil or does that count as a body fossil too?
Impression of a body fossil
so you wouldn't count lava casts (ie lava cast forest) as a trace fossil?
In my very amateur opinion, the tooth is from a mammoth and not a mastodon, as it looks more like an elephant tooth with its lamellae (elephants are much closer to mammoths than to mastodons). Mastodons teeth are rather pointy ("nipple-teeeth", as their name translates to)
