00:08 we were going to a lot of for this and they're watching, but

00:12 gonna be a recording anyway, uh the in the very beginning, uh

00:22 are microfossils, these are, how I know it says it right

00:27 They also uh there are some things are called also other sample of pots

00:39 look like this, like a model which are these this primary is the

00:48 , this was the Mesozoic and stuff we get this is a larger for

00:52 tell us, you know, right , I've got something. But then

01:01 we look at these more and more to find. But as the science

01:09 developed, this is where they And um smith was one of the

01:17 people to to actually start mapping things on final succession in the UK.

01:24 there was a couple of german folks at the same time and others in

01:29 . Uh it's funny when we look the history of science, it's usually

01:33 on the english writers when they figured something, but quite often the

01:39 the Germans and the french were doing else before that. And I know

01:44 a fact people in china were doing before. And uh and also probably

01:53 in Russia and that I know I don't know about the Middle East

01:58 people were were into that, I read that much from the Middle East

02:05 from Egypt or places like your Egyptian , I'm your, there's a lot

02:11 on in India, but that didn't until later until after, so related

02:16 the british occupation. Mhm. And so anyway again, why do they

02:29 were controlled by the environment that offers localized controlled by climate which is geographic

02:43 . And what else in really important deposits have to be, they have

02:59 be buried. But I think what trying to say is preservation. They

03:04 to get preserved in a lot of they're exposed at the surface for a

03:08 time you might be broken up for road. A lot of times there

03:14 things in estuaries that don't survive the record because there's a lot of physical

03:21 and there's also chemical changes that dissolve of these things. And of course

03:29 a carbonate setting uh carbonates can get and precipitated quickly. So a lot

03:37 a lot of fossils along the Barbary , Little fluctuations in the temperature or

03:43 sunshine can start dissolving stuff and then on when the temperature changes or

03:51 It could start precipitating like beach hard and stuff like that. And also

04:03 can completely, there's the answer. , so I like to call him

04:16 smith was the first one that came with the final succession but we we

04:22 call it fossil succession to include all which could be ignore fossils. Um

04:31 floral fossils Or funnel fossils, funnel is animals. And for a is

04:43 it's mostly plants. But what we included for now in definition is is

04:48 things that are kind of in between , bacteria and plants. When I

04:56 in school we had two kingdoms animal plant. It's getting really hard for

05:00 to get past that. And, now we have all sorts of tiny

05:05 uh, in the in the the of living things. And uh the

05:17 this worked out is the perception that of similar assemblages were time equivalent.

05:24 I'll show you some examples. similar sandwiches. Maybe different times with

05:31 same environment. They look different. different things. But assemblage looks simple

05:38 they have similar looking things and they're combinations like up here, if anything

05:48 preserved. So fossil fossil here here three times get out here and show

06:19 really incredible. Yes. Not. . Also it's far enough to make

06:39 less and less bunch of times. at face is there's lots of uh

06:48 in pollen get deposited here. They get out there, but there are

07:03 in column. You can actually get in the atmosphere and and fall wherever

07:11 want. But the, but the will change from that. So what

07:20 trying to get at is that, know that here, you'll see fossils

07:28 might be say very old something So they're making a similarity there then

07:43 only in time, but also again gonna be different process. It looked

07:52 same and I'll show you some cartoons of how that works. So,

08:03 , so are we recognizing a succession strata and therefore succession of fossils.

08:09 , and that is easy to do or rather we looking for fossils to

08:14 the strata and then the succession. uh, and in fact we

08:20 we do a lot of, a of both. The above is what

08:25 we do is try to not occurring continuous exposures or with regional correlation.

08:31 in reality we do both of these iterative lee and here's just an

08:40 Um, you know, to take relative position, relative age. You

08:46 think this is always under that this reality based on this cartoon. They

08:59 over the same period of time And this something, you know,

09:09 that sequence photography helped us realize is life is often happens because we have

09:15 that program it out like this when stuff coming over the top. And

09:21 these kinds of as they call them are just showing us that things been

09:28 . But one of the things that know is that this could actually be

09:33 one. This could be time to 50 one time scale like this and

09:43 equipment. So there's a, there's it's just a basic change or that's

10:02 . You don't have to get back . There's a deposition event later,

10:19 gets compressive. So plenty of surface here. So, you know,

10:26 is an it's not just it's in other words, this could be

10:37 grading wedge three a system later. right. As you can see in

10:50 like this. One way, it's , the localized sense. This is

10:55 facing ship because you have a thick if it happened this way.

11:08 So then the next So that's another have this was the positive might have

11:32 same amount of time. That's captain, this time, that's a

11:41 company. So now I'm confusing the out of right, what I'm trying

11:53 get at is actually interpreting it and can seem very uh difficult, but

12:01 , it all has to do with . When we see these things in

12:05 uh, seismic lines. We know it's a their layers in the determination

12:14 help to see those timelines. When see something like this in an

12:19 it was just about that size and outcrop. We would know that was

12:23 ship. Okay. And this is of how it was in the

12:31 we thought the seas came in and seas went out and I really like

12:39 diagram, but it's really complicated for familiar with stuff. But here you

12:45 see um, there's a deposition event then a marine and a fine rain

12:52 here, which is not a marina this case. This is a non

12:56 , um, like a floodplain to here with just leaves and here we

13:04 a sure thing. And this is optional. So we're going from Continental

13:12 . This thing right here is nearest your and we used to look at

13:26 but we would see in one formation next is it seems like the sea

13:31 in and the C goes out, comes in and all the formations are

13:41 . So this would be progressive and is transgressive comedies. So here you

13:50 short face or Deltek stuff coming over of continental onshore and marine on top

13:57 that, then it's procreating back So this is this is transgressive regressive

14:04 that's how we get up first. showed us sometimes such spaces larger

14:15 ships to changed character. Sure. uh you can also see that this

14:28 down significant is convinced. This part gets convinced. If you go to

14:40 water it gets condensed and this is because because you have a and it's

14:44 a thin video and here's another But these are also trying to show

14:55 that through time the fossils are This is all deep water. This

15:06 coastal, this is like spores and over here, which is just not

15:12 . So you see a similarity here the way they've drawn this cartoon.

15:17 know, this thing comes up in . Wasn't down in there, then

15:21 get up here and we have something what's similar is the assemblage has the

15:30 character in terms of uh non marines . We see uh I don't know

15:40 they showed it very well we can there's certain things in this coastal thing

15:45 are no longer up here. You see the mixing it up to some

15:48 these memory things in the Delta X example. And uh, and some

15:54 stuff here, uh that you'll see here as as transgressions happening and then

16:00 get the regression going on. You to lose these things. And then

16:04 you've got all the scores and scores at least. But they change and

16:11 haven't changed the leads in here, would help you can see them.

16:16 something that's round, here's one that of clover like over like clover like

16:21 ones are gone. These came in . Just these are you you understand

16:27 ? I'm trying to get it that have, we have assemblage here assemblage

16:34 and some bits here. Then we see things changing through time and age

16:41 . But all the way through we do see similarities in this

16:46 This time interval has an assemblage. this environmental deposition, this environmental deposition

16:54 an assembly to put through time and . Mm. And um I'm not

17:05 bother to explain this because it's um actually too simple and and I might

17:11 you but looking here. Um I off short, this is captain,

17:22 can deeper. We end up with groups of when these are benefits

17:33 You can get some blankets here, the percentage of this normally is the

17:42 , right? Um 200 ft. ft. Yeah, actually, 300

17:56 is where the break was in uh m, 200 m because it looks

18:11 it's a Anyway, we have a deposit, here's time will show and

18:20 It gets deeper than 200 ft. , get water. Yeah, I'm

18:29 why don't we take a break right ? See if I can pause my

18:37 because I need water. I'm gonna the key and I'll be able to

18:40 this up. But if you guys , I can bring you uh both

18:44 you a a bottle of cold water of my refrigerator. Did you just

19:34 the video? I don't have a button on here. Is that the

19:40 thing? No, so I'll start . And so do you receive the

19:51 I return to? I do have . I thought it was in my

19:56 , but it's not. I'm we're taking a break. Okay?

20:00 , so I'm gonna I'm pausing I can't get the key tomorrow.

20:07 gonna, I'm gonna go over and if I can get it right

20:09 Okay. Oh, And my next . Yeah, great. We have

20:58 . And
