Machimosaurus: The Largest Amphibious Crocodile Relative of the Jurassic Period
Вставка
- Опубліковано 23 лип 2024
- Machimosaurus was a genus of semi-aquatic, marine crocodile relatives that lived in what is now Europe and Africa from the Late Jurassic to Early Cretaceous. It grew up to 7 meters long. While not as large as small later crocodylomorphs such as Sarcosuchus and Deinosuchus, Machimosaurus hugii was perhaps the largest crocodylomorph known from the entire Jurassic period. The similarly large Machimosaurus rex was also first member of Teleosauridae, the larger clade of marine crocodylomorphs Machimosaurus is a part of, known from the Cretaceous period.

Your quality is so much better. Compare the narration.
@@thelaughinghyenas8465 Thanks.
Whether a remake or not it was good and well made. Your use of images make it much easier to understand the subject! I am a late comer to your channel have loyally watching it since my 1st visit. Stay well, And have Better New Year in 2022 as well!
15 meters? Wow!
I love how you talk about lesser-known prehistoric creatures on this channel and I hope to see more in the future.
Especially Crocodilians and crocodiliamorphs
The sad thing is the Tyrannosaurus rex is a very unique and interesting dinosaur. However, it has been greatly overemphasized compared to other prehistoric creatures while its unique traits are often underemphasized
This should just be the unofficial crocodylimorphs channel in all honesty. I love it yet is so afraid of these stealthy monsters.
well, I love them.
Those big opening behind its eyes are vital in modern crocs for heating blood in the skull(in thermal imaging of basking crocs this area glows bright with hot blood near the surface). If machimosaurus was doing the same thing i imagine it would not need to bask for nearly as long to get to tempreture. Also those 2 rows of huge osteoderns look like a quite efficient solar array for quickly heating up.
Tyrannosaurus-Rex: Finally! A worthy opponent! Our battle will be legendary!
You are improving so much, it's quite impressive! I also really like the vast variety in which critters you cover, too. There's so many ancient critters that are nearly totally unknown by most people, and completely unknown by the average person, and that's a shame. I'm glad you're working to help fix that.
This was fascinating. I appreciate the way you break it into sections, so that viewers can quickly find a part they want to review.
Despite being a komodo dragon myself, I really act like this amazing "croc"
Who asked
Another great video
This video was so amazing and I like it,also Machmino is my favorite prehsitoric Crocomorph
Very interesting. And, the stuff that nightmares are made of!
I love these remakes! Shows your dedication to providing top quality content!
would you consider covering some of the marine croc relatives in the future?
Pretty interesting - thanks a lot for sharing, and have a great new year, my friend!
Thank you for being my go to channel for ancient crocodilians, they are my favorite animals and all of these videos have been wonderful to see
Well, there goes my dream of paddling in the oceans of Jurassic Europe.
Not willing to see if Nigel's Liopleurodon repellant also works on thalattosuchians?
@@chimerasuchus LoL it's tempting, but I'm not a fan of mystery toe nibbling.
@@chimerasuchus LMAO
I imagine because of all the repeated convergent evolution there are a number of planets with highly intelligent Crocodilomorphs.
If there is water based life there, i would expect a lot of fish and crocodile like lifeforms too on alien planets!
Great video. Thanks.
great channel very informative and accurate 😍.. I wish you could also make a video regarding theropod lips
Why is this channel being recommended to me and why am I loving it?
my favorite part about machimosaurus is that it represents the first step towards the metriorynchids, the only fully marine crocodiles and as such only fully marine archosaurs
Always a favorite subject. Liked visiting gator farm as a kid. Thank you for vlog ✌️✌️✌️
Interesting video
So did this guy evolve into Sarcosuchus in the Cretaceous? I can totally see the similarities
No. Sarcosuchus was a member of the clade Pholidosauridae, not Thalattosuchia.
@@chimerasuchus ah! I see, thank you for the information, subscribed!
To
wow i did not know this was a remake.
Question: would Machinasaurus pick up a fight with razanandragobe?And,who would win?
Perhaps, but at least on land Razanandragobe likely had the advantage. If they ever encountered each other as adults, they would probably avoid one another.
@@chimerasuchus thank you for the reply
All good stuff.
Very cute 🐊.. beauty is in the eye of the beholder 🐉
good show
Fascinating creatures!
Please do a video about the alligator; I am from Florida, but just found out that China also has it's own endemic gator!
Such slim jaws, yet still a formidable hunter. This reminds me of phytosaurs, tomistomines, and Spinosaurus.
I love Machimosauruses.They kinda remind me of rhamphosuchus.
Good stuff!
Great
machimosaurus rex sounds badass
Can you please do a video on Prionosuchus? Thanks!
On the topic of marine crocs, any chance you’ll do a vid on metriorhynchids?
Probably, though with the sheer number of other videos planned that will be some time from now.
Since a good majority of your videos are based on prehistoric crocodiles, any chance of doing a video about Leidyosuchus? It was a Cretaceous Alligator.
Side thought: Mosasaurs must gave birth to massive rate, parental care and/or recognized there young like those Aussy lizards. Think of competition
and did Mosasaurs have two tendrils if you know what I'm saying.
I believe mosasaurs did give live birth (at least, other marine reptiles did), so that wouldn't be surprising.
On the other hand, parental care post-birth is extremely rare in the ocean. I'm not sure if our croc boi can keep track of the numerous offspring or incubate them when food in the ocean can be pretty far away. Even then, Crocs only raise young long enough that they can not get easily eaten. If mosasaurs get pregnant, the young are likely large enough by birth to be independent.
Well mosasaurs took to the oceans after the cenomanian turoian mass extinction, and it seems machimosaurus died out millions of years before this. But icthyosaurs, plesiosaurs and pliosaurs would have been contemporary and all gave birth to live young. I'd agree that they would have likely looked after their young like dophins and whales do(as in the case of the icthyosaurs giving birth the baby is not an inconsiderable size, and its unlikely a mother can fit more than 1 or 2). Its not really a leap imagining them forming pods like dolphins and killer whales as well. I think the ocean, particularly when its full of large reptilian predators would sorta promote novel adaptations and close bonds within the group and with partners.
@@rileyernst9086 "mosasaurs took to the ocean" I thought they were pliosaurs?
I agree that few offspring would make parenting more viable, but I don't know if it would give enough selection pressure. Sharks that produce live offspring do not raise them as they are fully capable of surviving and cannot get milk. Unless either of those two factors are changed, I see no (strong) reason for parenting in marine reptiles.
Still want a vid on kaprosucus
Hey quick question, where do you find so much obscure info? Is the wiki accurate?
The best place to start is the technical literature. When available, it is also a good idea to check for press releases about a discovery, which often provide additional information not in the paper. Wikipedia is usually accurate and is rarely flat out wrong. However, it is often out of date and a lot of the language is about as technical as the paper itself.
@@chimerasuchus thanks, it's just at times I see some not very accurate things like a giga outweighing a rex
6:46 Where did this Illustrated battle come from?
Image credit is given in the top corner.
@@chimerasuchus What I mean is, 6:46 is it on some book on Dinosaurs? Plus, it better be in a Hardcover book. I like Hardcover & Library Binding Books better than paperback books.
Perhaps trivial, but 'hugii' should roll off the tongue as 'hyoo-gi-eye', and not 'hyoo-gye'. Latin pronunciation rules demand that there should be a clear tonal distinction between the two 'i's'.
Based on its skull shape it was a pescatarian crocodilimorph.
Machimosausus eated mostly a fish. But if a far smaller false gharial can eat goat or a dog so 7 meeter long machimosaurus could eat every animal that Saltwater/Nile Crocodile eats. Humans included.
What is a machimosaurus doing in Switzerland?
Back then most of Europe was ocean!
I thought it was pronounced MA-CHEE-Mo-saurus. Thanks for the clarification.
Great video, but is anyone else getting audio warbling? This whole video sounds like him speaking over someone with Parkinson's disease mashing the higher pitched piano keys at a low volume.
Did you know machimosaurs was in animal revolt battle simulator
Yeah and thier Purussaurs looks more like Dienosuchus then the real Purussaurus.
Any notable large Amphibians during the Jurassic, like a predecessor of Koolacucus
There were, such as the 2.7 meter long Siderops.
@@chimerasuchus ta very much
what abaout purussourus
What does it mean when he said they were they’re not crocosaurids? Were crocodiliomorphs just dinosaurs that looked like crocodiles but weren’t?
Crocodilia is defined as the crocodile crown group, basically all living species of crocodylomorphs, their last common ancestor, and all of the extinct descendants of that last common ancestor. All of the extinct crocodylomorphs who are not descended from that most recent common ancestor are therefore outside of Crocodilia proper. Many crocodylomorphs were already very crocodile-like, though some like Machimosaurus may have evolved a crocodilian-like body convergently as a result of evolving a semi-aquatic lifestyle.
crocodiles back in the day were divers
Machimosaurus is shown to have five species. Lately there has been talk that some smaller species of Dino Carnivores may be juveniles of some of the larger Carnivores. If any of these Machimosaurus species were found temporally near each other in the fossil record, is possible that they may also be juveniles of one the other Machimosaurus. Keep these wonderful programs coming!
I misread the name as Machismo-saurus 😂😂😂
At the start you said sarcosuchus right but you don’t say it like dinosuchus you say it like deen-o-su-ch-us
If you want to use the name of the species you are dealing with, please learn the Latin pronunciation instead of bastardizing the sounds with thr English pronunciation.
