@brookesef Thanks! At some point I plan to make more, perhaps a whole free course on introductory geology. It's just a time thing. I now run a small paleontology museum as a side volunteer gig (www.capebretonfossilcentre.com), so summer plans keep getting postponed to the next year. Maybe next summer!
@@jasonloxton2785 Wow that would be awesome if you did! No stress though - I would love to visit the museum someday as well! I'm an anthropology grad but I always find paleontology and ancient earth ecologies so fascinating - sometimes I wish I went down that path instead haha.
I just finished watching through all 5 videos in this course and I have to say, your cadence combined with the annotations made it so effortlessly easy to follow along, it’s like the information was being telepathically transmitted to my brain😅
Excellent content! I have been reading and viewing all I can about the rise and fall and rise of the synapsids for about five years. I graduated from college over fifty years ago (English major) and I continue to learn more and more about our amazing journey on this planet. Thanks again and my wife and I are hoping to fly to Nova Scotia in 2022 to see some of the sites mentioned here. Regards from Kent, Ohio!
Thanks. These videos were never meant to go online. They were for classes when we were forced online to finish up the semester. Really glad people are enjoying them. I wish I had the whole semester available but sadly it was just the final few weeks.
@@jasonloxton2785 With content like this I think I might be able to adjust to online learning. Best to you and your colleagues and students and here's hoping your next term will be a normal one. Regards...
Jason, you are an formidable teacher. These lectures are interesting, made with an amazing energy and sometimes quite funny. I’ve always had an interest in palaeontology and how life evolved and these lectures are a real treat. Your students may count themselves very blessed with a teacher like you. Thanks for posting them so we can all learn from you.
Albeit a college lecture, this is a MUST SEE for anyone that shows interest in dinos, 12 and up; for the time investment of 75 minutes, this is packed filled facts that lays an incredible foundation to spring board from. Pad and paper ready for furious note taking, and TYVM Professor Loxton.
so enjoyable, I was hooked to all five lectures! Well done Jason! Naturally presented with scientific rigour and humour! Great how you are weaving the latest publications into your lectures and highlight controversy and areas of contest because this is what Science is about and how knowledge progesses. I have strongly recommended these lectures to friends and family. Makes me want visit Canada again and travel to all these fossil sites and the Natural History Museum of Ontario, spend my holidays in Nova Scotia - alas I am a foreigner in Brexit country...
Thank you for putting these lectures online, i really enjoyed them. Its hard to find decent, challenging and correct content on youtube these days (or any other medium i might add..). I sincerely hope you will keep posting your lectures in the future. big thumbs up from Belgium.
Brilliant! Thank you Jason for posting these lectures. I'm in the UK (living between the shore of the Cretaceous in-land sea and the Ediacaran rocks of Charnwood Forest) and when this current nastiness (Covid 19) stops, I intend to visit Nova Scotia
I watched these five courses with great interest. I have been reading and studying earth sciences for a long time, and one of my concerns is the apparent lack of cohesive synthesis - specialization is justifiable, but there is a great need for realizing that the Earth functions as one system. Human civilization has attempted to separate human activity from the environment, with now obvious results. Your courses illustrate the alternative - the only direction that may ultimately diminish the destruction of the environment - and civilization as well. A global perspective...Great message. I hope it catches on, really fast.
14:21 what do you think about the stabilization of the inner solar system and increasingly less interstellar flack bombarding our planet.? Seems that the two things that effect are large volcanism events and large impact events. Recent speculation on impact created volcanic ties would explain many things. Seems quite plausible , like the needle that broke the Camel's back. Seems that it's 180 from impact on our globe in a few occasions that their is continuity.
A really entertaining lecture. I like it how you cited various UA-cam videos that you apparently thought said something best. An elegant and efficient way to convey information.
Thank you for posting these! The Palaeozoic is awesome, particularly the Cambrian. I was introduced to it with things like Wonderful Life and Walking With Monsters.
Actually, kind of. I am not a vert paleontologist, so am not up to date on the latest (plus, the jury is still out), but feathers evolved for thermoregulation/signaling (two things bird use them for now; we have them on dinosaurs that very clearly were not flying). Flight most likely evolved in arboreal species, as a gradual extension of gliding. We can see pretty much every stage of the evolution in gliding species today (gliding, with some adaptation to increase surface area to decrease rate of drop, is super common in the animal kingdom; even snakes do it!).
@@jasonloxton2785 If you had the choice how would you divide up the content? Would you spend as much time on each period of the Mesozoic and Cenozoic as you did on the Paleozoic?
I would love to borrow your book rise and fall of the dinosaurs! You might not get it back though… i wish i could afford to buy it but i’m going through chemo for stage 4 breast cancer right now
Huh. Weird. I had to actually rewatch because I didn't believe that I could have said 'shark' (I love Basilosaurus, they're my favorite whale!), but there it is. Weird brain fart. Thanks for pointing it out.
I know why there was a diversity plateau at the end Permian, it's because of the uncrossable interior, it limited critters' ability to move to a new environment there by favouring specialization over diversity...the reason we are so diverse now is because critters can migrate to more favourable locals for birthing / feeding. ..IMO
I’d like you to take a job as the media liaison for global disasters: “so, I’m just gonna go through a list of everything that’s dead! Ok, this guy, DEAD. These guys, they’re all DEAD!”
I would posit that the reason for greater and increasing biological diversity after the Permian/Triassic extinction is the evolution of widespread capacity of imprinting behavior. I.e., animal species which can learn simple behaviors from parents, including selectively eating differing foods.
Jason, what did you think of BBC's 2006 three part series "Walking with Monsters"? Dimetrodon gets a big mention in the second episode ( ua-cam.com/video/yYGRBbFAmgo/v-deo.html ) and ( ua-cam.com/video/7T9JOwrMds0/v-deo.html ).
what causes the continuing increase in diversity after the PT extinction? isnt it an increase in environmental diversity? big and small land masses spread out over many latitudes, lots of different environments and seasonal cycles, lots of niches to fill, lots of species filling them? idk thats what my first thought was
Not super up to date, but my understanding is that the emergence of a few specific life strategies likely was a major driver, including burrowing in clams. The real mystery is not why it rebounded, but why it hit level that were beyond what seems to have been a max for a couple hundred million years before. We had continents in a diverse array of positions. There's likely also some abiotic driver, as you note, but at least when I last looked at reviews (I am not a specialist on this) it looked like it was to a large degree driven by a few major evolutionary innovations, which created new niches, and drove specialization.
Fascinating subject matter, but scribbling all over the screen and the inability to stick to metric measures muddles it all and is massive distraction. That plus the usual "nobody knows..." assumption of local ignorance being universal. Best to scroll off the messy visuals and just listen to the lecture. The take away line from this was the suggestion to "read literally" "The rise and fall of dinosaurs" And the oopsies of Basilosaurus, the whale ancestor, being called "sharks".
Canadians mix metric and imperial. Just just how we roll up here! And yup to Basilosaurus brain fart. These were all recorded in real time for a class. They're off the top of my head. Little errors creep in when you're talking without notes for an hour! :)
Jason, I watched all 5 of this series and loved them. Thanks for posting so those not in your class could access them.
Great! That makes me happy. I just put them up on a lark, since I had them already created for my class. Glad that people are enjoying them!
@@jasonloxton2785 Thank you very much :)
These lectures are AMAZING. Love them. Make more

Just discovered your channel , while "quarantined" in Switzerland. Your commitment and quality classes definitely need to be known, thank you!

Just asome, i wached all, and i learn and laugh a Lot ja. Thanks so much Jason. A Big hug from Santa Fe Argentina ☺️
1:09:10 toothed whale, not shark
Did a lizard keep jumping off a rock for alot of generations until it grew wings and feathers?
Actually, kind of.
I am not a vert paleontologist, so am not up to date on the latest (plus, the jury is still out), but feathers evolved for thermoregulation/signaling (two things bird use them for now; we have them on dinosaurs that very clearly were not flying).

We can see pretty much every stage of the evolution in gliding species today (gliding, with some adaptation to increase surface area to decrease rate of drop, is super common in the animal kingdom; even snakes do it!).
How come you had to rush through everything from the Permian on in a single video?
These lectures were made for a course (I put them up on UA-cam as an afterthought), so I was constrained by the number of classes in the semester. :)
@@jasonloxton2785 If you had the choice how would you divide up the content? Would you spend as much time on each period of the Mesozoic and Cenozoic as you did on the Paleozoic?
good stuff
Gave rise to toothed sharks like Orcas????
I would love to borrow your book rise and fall of the dinosaurs! You might not get it back though… i wish i could afford to buy it but i’m going through chemo for stage 4 breast cancer right now
Hope you are doing OK!
Umm, you referred to Basilosaurus as a shark twice, it is in fact a whale. Otherwise excellent series.
Huh. Weird. I had to actually rewatch because I didn't believe that I could have said 'shark' (I love Basilosaurus, they're my favorite whale!), but there it is. Weird brain fart. Thanks for pointing it out.
Have you thought of writing a textbook or two based on these five lectures.
I'm going to guess that the increase in diversity is related to flowering plants. Lots of niches, lots of symbiotic relationships.
I know why there was a diversity plateau at the end Permian, it's because of the uncrossable interior, it limited critters' ability to move to a new environment there by favouring specialization over diversity...the reason we are so diverse now is because critters can migrate to more favourable locals for birthing / feeding. ..IMO
I’d like you to take a job as the media liaison for global disasters: “so, I’m just gonna go through a list of everything that’s dead! Ok, this guy, DEAD. These guys, they’re all DEAD!”
Maybe the higher biodiversity today is due to the highly fragmented continents.
I would posit that the reason for greater and increasing biological diversity after the Permian/Triassic extinction is the evolution of widespread capacity of imprinting behavior. I.e., animal species which can learn simple behaviors from parents, including selectively eating differing foods.

There is new hypothesis that terror birds were herbivores. A little play of imagination.
