Dr. Polaris I got some fantastic news, a few days ago I was reading my newsletter from Live science and it broke the story about a amateur fossil hunter discovered a Columbian Mammoth's tusk in rural Madison county Mississippi near a riverbed and according to the article he contacted and agency there and then they called another agency there as well , and they said those types of fossil's doesn't preserve well and since then several newspapers have picked up the story and even the Smithsonian magazine 🙄 mentioned it as well it was 7 ft long and weighed 600 pounds or more 😮 I'm hoping that I'll find something similar to that
Dr. Polaris often digs up a lot of obscure background information on a level I haven't heard on most of the other youtube channels specialising in obscure weird prehistoric animals.

A new Dr. Polaris video is an insta-watch for me, you've quickly become one of my favourite channels for videos about weird and obscure prehistoric animals. This one is interesting because it shows how quickly scientific consensus about dinosaur evolution changes. I remember that the books about dinosaurs I read in the 1990's unambiguously described Herrerasaurus as an early theropod dinosaur.
Mind if I ask what background music did you use for your videos. Both from the intro and the rest of the content? Really informative videos and I am looking forward to seeing more from you.
Thanks for the kind words! My intro music is (perhaps somewhat randomly) Arctic Antics from Crash Bandicoot: The Wrath of Cortex. While it’s a pretty flawed game, I played it quite a bit when I was young and most of the music is legitimately really good. The main music is called Hozen Theme from World of Warcraft; I’ve always enjoyed how mysterious and calming it sounds.
Hey Dr. Polaris, right after the evolution and the history of the Hadrosaurs, Dryomorphas, why don't you get to think of a suggestion and creating a RUclips Videos all about the about the evolution and the history of the Prehistoric Marine Reptiles called the Palaeophiidae (Palaeophis), the Extinct Marine Serpentes (Snakes) that are the relatives to the Extant File Snakes, such as Archaeophis, Palaeophis, and Pterosphenus, in the next couple of weeks to think about that one coming up next?!⭐️⭐️⭐️⭐️⭐️👍👍👍👍👍
@@dr.polaris6423 I've always loved your theme song and never knew where it came from. I agree about the background music; it reminds me of 1950s/early 1960s science fiction soundtracks.
I too was curious about the intro. I mistakenly thought it was from a 60s/70s eclectic band like the Bonzo Dogs, and harking back to the 1920s/1930s. It sounds rather the kind of thing that Vivian Stanshall would have composed/resurrected.
Is Dilophosaurus really a separate family from Coelophisys beyond any doubt? because Gojirasaurus seems to be like a step before a bodyplant like Dilophosaurus...

All of the larger End-Triassic theropods were restricted to higher latitudes as larger dinosaurs couldn’t handle the droughts of the Pangean interior (unlike large pseudosuchians of the time).
I didn't know that, there has to be a reason it took a while for theropod dinosaurs to replace all the weird Triassic dinosaurs as the world's dominant predators. I am guessing the late Triassic extinction took out most of the crocodile relatives that were better adapted to life on dry land than in rivers, the same way as the Permian extinction got rid of most of the Gorgonopsids? (early mammals who were the Permian's dominant terrestrial predators - looked like a weird cross between dogs and monitor lizards, Dr. Polaris has another video about them) Some of the weird prehistoric crocodiles remained dominant in South America long after the meteor and well into the Miocene, however, namely the Sebechosuchians.
I really like the Herrerasaurus animations in PBS The Dinosaurs! Episode 3 (1992). They eat a Thrinaxodon, kill a Rhynchosaur and get chased off by Saurosuchus.
This is very interesting and scary at the same time 😮 and they also discovered a dolphin type crocodile from the ancient times, but didn't you cover this one before 🤔🧐🇬🇧🏴💂♂️☕
A bit unrelated but I have a theory on Ornithischian Dinosaurs, I remember a study saying how oxygen levels were lower earlier in the Mesozoic & how Saurishian Dinosaurs had more efficient respiration because of their air sack systems. This is what I'm getting at here, is it possible the increase in oxygen in the Cretaceous was linked to the increased Ornithischian diversity around the same time?
I mean not necessarily because you have to keep in mind that some ornithschians were already getting large by mid-late Jurassic such as the stegosaurs, that and by the late Jurassic both ankylosaurs and ornithopods were already appearing and becoming more prominent.
@@wallace2286 I'm aware of Stegosaurs, but perhaps they could have been an exception as no other ornithischians were getting as large in the Jurassic. The only other Jurassic ornithischian I could find reaching somewhat large sizes was Camptosaurus, with some individuals reaching the 20ft mark. But again, with their rarity they can just be exceptions.
@@cro-magnoncarol4017 they were others though camptosaurus was just one of several medium to large size ornithopods including draconyx, hesperonyx, owenodon, and the largest oblitosaurus which reached massive iguanodontid like sizes in the late Jurassic of Iberia.
@@wallace2286 I looked it up, from what I could find Oblitosaurus was either 19,8ft or 20ft-23ft. Which actually puts it in the same size range as Camptosaurus. Impressive for a Jurassic Ornithopod no doubt, but it was no Iguanodon.
Paleontologists look for certain anatomical details of fossilized bones which allow them to place extinct animals into certain lineages. Newer detailed studies have shown that Eoraptor possessed certain physiological traits of Sauropodomorpha, including a downturned jaw tip and a long deltopectoral crest on the humerus.
Your vids are great but consider changing that clown music at the beginning. I recommended your videos to two of my friends who are beginning to take interest in this sort of thing, but both told me they turned it off as soon as the music began. So now they are watching someone else’s stuff. 🤷🏻♂️🤷🏻♂️🤷🏻♂️ Just sharing this with you. The music is super annoying. Take it or leave it.
As a herrerasaurus fan, this makes me happy. Herrerasaurus, and triassic dinosaurs in general, need more love.
As a herrerasaurus I appreciate your support
Chimerasuchus gives them love on his channel
there are many species of herrerasaurids all over the globe
Anyone else remember the ending of Walking with Monsters when Euparkeria starts changing into Allosaurus?
Yeah 2005 was a good year for Paleo media
That was perfect ending to ends the show as it feels like prequel to "walking with dinosaurs"
I do!!
Yeah

Theropods are a neat group that still live with us
put a hen next to a T-Rex and you notice they have very similar builds
Ahhh, you have seen my wife ...
They don't. The birds are related to the dromeosaurs and were there alongside dinosaurs.

That was very interesting. The relatively small, agile dinosaurs have always been my favourites.

it looks like a very ornery ostrich, to me
also the development of primitive feathers. btw amazing video! ancient species are never boring
And some people think that dogs would beat them in an evolution arm's race.

These videos would make for amazing content to show at natural history museums.
I continue to feel amazed that before the reign of mammals Earth was actually dominated essentially by dragons
it is a widespread theory that some dragon legends were caused by people finding dinosaur bones and not knowing what to make of them
Wouldn’t want to meet one of those in the dark woods!
these were the ancestors of the large theropod dinosaurs that would arise during the jurassic. btw the front limbs look so funny

That’s exactly my point, theropods were unable to take over in the Triassic.
In PBS the dinosaurs, episode 3; Dr. Paul Sereno wept when he discovered a perfectly preserved Hererrasaurus skull
Well, who could blame him?
All species had humble beginnings, even the dinosaurs.
2:43 I'm really glad for size comparison guy that he's armed against those predators. ^^
