Phytosaurs: Crocodile Cousins
ฝัง
- เผยแพร่เมื่อ 21 ส.ค. 2024
- Phytosaurs were a lineage of very crocodile-like Triassic Archosaurs. Indeed, they dominated niches that in modern times are held by crocodilians. Despite their overall similarities, Phytosaurs possessed nostrils located on the tops of their heads, not at the tip of the snout and their ankle structure was fairly primitive. Some genera were massive ambush hunters, while others were smaller piscivores.

I thought you were merely a talking bear. Now I find out you're studying for a PHD, Well done!
One smart bear 😎😎
Art history I’m sure
phd in smugness probably
Phytosaurs and crocodilians are one of my favorite examples of convergent evolution.
Also, add on Prionosuchus.
Agreed, but the iguana/tuatara similarity still freaks me out even more.
"Dude, let me in. I am a herbivore"
A Phytosaurus, probarly.
Lol ironic considering they turned out to be hypercarnivores.
@@dr.polaris6423 I remember as a small child I had a paleo-encyclopedia with comical cartoonish illustrations and the phytosaur was the only critter in the book that utterly terrifying, and given that I am Greek I found it ironic that its name implied herbivory.
I'm wondering how sarcastic the sarkastodon is lol.
One of my favourite genus names!
I know right XD
XD 👍🏼
No intro music today was strange, so I sang along anyway :D love watching your vids regardless of upload schedule. Just means there’ll be more anticipation for the next one. Keep it up man!💜
Thank you so much for your support!
2 times a month is twice as much as I do, no stress brother.
Cheers!
And unlock dinosaur genetics it’s basically finding lost keys to lock doors in a maze
Don't worry, I think we worked out you were a bright spark... Sharper than most of the people on TH-cam, that's for sure. I wish you luck in your studies, these are strange times to be at university.
Don't worry about changing the schedule. I hope all goes well for your studies. Completing PhD work takes a lot of time. We're all proud of you for sure!
Thanks, really appreciate it!
Hello Dr. Polaris. Was recently in St. Johns AZ and obtained permission to find remains of the fascinating Phytosaur. We found scutes, bones and lots of coprolite with little bones in them. So much fun. We have sliced into the coprolite and actually found some bones fragments and what appears to be some pink opal. Wish I could post a picture, but you've probably seen something familiar. Going to subscribe to listen to more of your videos. Thanks for sharing.
You’ve helped me drift of to sleep since I found your channel. Thank you my special Bear x
Thanks 😄
My favorite!
To add to the general conversation something I've noticed that after every major extinction it seems the first to re-occupy the land (when land was occupied), is Alligator look-alikes and in the water Crab like creatures, even before there were archosaurs the Amphibians filled in behaviorally as Crocs. Starting with the Cambrian, this is true for almost every major apocalypse.
Twice a month is perfectly fine upload schedule.
Thanks, glad you agree.
@@dr.polaris6423 yeah don't sweat it man real life stuff is way more important anyway plus you're better than I am I don't got too much important stuff going on and I barely ever uploaded crap so at least you're better than I am
@@chancegivens9390 Thanks!
@@dr.polaris6423 ja mon
Fantastic video! Good luck with your studies at King's!
Hello, Dr. P. I love your channel and subject matter. Keep up the great work, and much luck in your endeavors.
Cheers :)
Twice a month is better then not at all doc. Besides u can't help it the work load being expected of u is extreme prior to a youtube channel lol. Good luck and keep up the great work, always make time for self and fun too
Thank you! Glad you understand
Good luck with the PHD 🤞. I will miss your exaltan regular presentations, and will keep a look out for your new videos; though your old ones merit watching more than once.
Maybe having the nostrils on top of the skull gave the phytos an edge as far as being stealthy and inconspicuous. A huge redondosaur could conceivably keep an even lower profile in the water than a smaller salt water crocodile. Just a bump on the surface...
I love watching videos of ancient versions of crocodilians
Go for it. Best wishes. Thanks for all your hard work. Much appreciated.👍👌.
one more difference: they don't do the death roll
Yep, absolutely true.
@@dr.polaris6423they might of
The proto-whales of the archosaurs.
elaborate
More like crocodiles' rich gay uncle that left them a house and his buziness after he died childless.
Love your audio details and good luck in your studying and as I remember a nice hill to walk up
I sure don't mind waiting a bit for your videos if it means furthering your education. I'm a college student myself and coincidentally doing my thesis this year. I know it's a lot of work and doesn't leave you much time but you must prioritise your degrees
Thank you. Very interesting
I love phythosaurus.
@ 3:53 I know we're looking at a fossilized skull, but did anyone else see that as Kanye's newest Yeezy sneaker? I can't help it. It snuck into my brain!
Так интересно, большое Вам спасибо. Учёба моя - 50 лет назад.....
Good luck with your paper 👍
I bet b unlocking the genetics of crocodilians perhaps unlocking phytosaurs
I love this chabnel
@ 0:33
I'm in the same league, only a little earlier in the process. You got any advice for me? (I'm sadly not in Britain, but Kansas).
👨🏻🏫 Hello. Mr Teacher here. My advice to you is this. Organise your schedule and keep to it as much as possible. Organise your research results very carefully. Include regular reviews of your work. Organise and organise and . . . you follow me? That way you should keep focused on task and achieve excellent results. This is how I obtained my five degrees, albeit not at PhD level (so far). Kind regards from England 🏴.
Phytosaurs are like crocodilian placodonts 🐊
Excellent video Dr. Polaris! I have a question, what does it mean by phytosaurs having primitive legs compared to crocodiles? In what ways does the bones look more akin to basal archosauriforms?
Good luck :) I have a friend whose son got his PhD last year :) Sydney University.
Enjoy your video's, I rate you higher than your university
Sounds like a vitamin
That’s has to be the biggest I agree moment in my life
Where's the Gator Boys when you need them?
Dude I swear I get lost in your videos
Crocodile cousins
5:05 what were those lizard like creatures supposed to be in the Rutiodon picture?
I heard that there are some Non Phytosaurid, Phytosaurs. What does this mean?
Are Ghariels still alive today? Also aren't they only found in India?
no and no
here's some speculative evolution ideas: what if one of these like the mystriosuchus had more time to evolve and became fully aquatic? Interesting to think about, though now that I think about it more the Late Triassic oceans already had a lot of large predators in the icthyosaurs and plesiosaurs....
..and in the Jurassic would have basically just what you're suggesting, courtesy of the Crocodylomorpha clade (close to and including the lineage that would survive til today.)
You probably know about the teleosaurids and other marine 'crocs', but had to throw that out there!
A polar bear in university, dont tell trump
What does basal and derived mean
Basal; On a cladogram or phylogenetic tree, the lineage nearest the root or for clades further away from the root, the lineage nearest the common ancestor. In other words, the lineage/s that evolved first after a split.
Derived; a trait evolved in a lineage of a common ancestor, but not present in that common ancestor.
There's more to it, and perhaps the terms I used also require explanation; let me know.
Ha fightosaur
I wonder if they could aestivate
9:20 No, no it didnt, there is no such thing
vermin
The green house effect does exist :|
Don't pronounce "genera" like genre, please! Besides genera is plural only!
No offense but you sound elderly. That or a heavy smoker.
He’s a fancy bear. I’m not sure what your hearing pal.
