https://www.youtube.com/watch?v=8g5XG5o2CtIWe're gonna be looking back on lipped T. rexes the same way we're looking back on Nanotyrannus being a juvenile T. rex; wondering how the fuck that stupid shit ever became consensus in the first place.
>>5098966Nah they 100% had lips, get over it lil JPfag kek>10/10 video>10/10LMAOOO sure thing bud
if trex had no lips, how did I make out with one
>>5098973That was his pussy lips
>>5098967JP dinos had lips. The raptors and dilo even moved their lips when they snarled.
this only makes sense if you believe that they had their jaws smashed close so tightly to point they would’ve been damaging their oral tissue inside the mouth.
>>5099031Explain the indentations at the roof of the mouth if they didn't do this.
I am on the lips side of the debate but i hate when people act as if lips on theropods are a proven fact and not a hypothesis. People really need to learn the distinction between those two terms.
>>5098966Impossible, animals can't have exposed teeth or else they would break >>5094297
>>5099035deformity that occurs during fossilization. Stan in particular has his teeth falling out exposing the roots and his overbite isn't natural, his left and right mandible are two different sizes. the indentations were made when the skull got compressed.
>>5099039correct, teeth are perfectly fine being exposed to the elements. but the reason why lips exist is to keep the oral cavity and everything beyond it moist and free of infection. that latter part is important because if your wondering how crocodiles get around not having lips to keep their mouths moist while also staying out of the water for extended periods of time like during aestivation? they have a palatal valve, that semi aquatic adaptation also allows them to seal their throat to prevent their insides from being exposed to the elements. so they can allow their gums and tongue to dry out without a worry in world. this also brings up a interesting question on whether or not any dinosaurs had this adaptation? spinosaurids could be a candidate.
>>5099128Why can't faggots explain things like this instead of making up shit that can be disproven by looking at a cat?
>>5099038I was on the lips side until the video in OP.I think it's silly that the lips side treats lips as modern and accurate and no lips as outdated, when a lot of outdated paleoart depicts dinosaurs with lips since they were just seen as big lizards. Ironically now that we know how different they were from lizards, lizard features are getting brought back.>>5099128If T. rex closes it's jaws tight enough to where it had indents from it's bottom teeth on the roof of it's mouth, then would it even need lips to keep their oral cavity moist?
>>5099143see >>5099091 and give this a read.https://qilong.wordpress.com/2014/03/17/the-emaciated-tyrannosaur-a-reply-to-ford-1997/stans skull is very well preserved but not perfect, it even has two holes punched in the front of its mouth. this simplified cross section shows a normal skull compared to compressed and deformed skulls. maybe rex and other long toothed theropods could've had the tips of their teeth poking out of their lips like various fanged animals but who knows.
>>5099132it’s called effort posting and it requires anons to actually watch the video, ask themselves questions like how do crocodiles stay on land without lips, and doing the bare minimum of research to answer said question.
>>5099128How do birds deal with this problem? Not all species have tight fitting bills.
>>5099159honestly after looking at several different kinds of birds it seems like the vast majority of birds do have tight fitting beaks, even crossbills have tight fitting beaks. the only exceptions seem to be hornbills which seem to naturally wear the inside front part of their beak down since they use it for climbing, and large macaws which also wear their beaks down from climbing, manipulating objects, and having big bite forces. macaws do have dry mouths but that’s more so of a manipulation adaptation since they use their boned tongue as a finger to help manipulate the hard food they eat.
>>5099239Macaw tongues are fucking creepy
>>5099151Your illustration seems to neglect the point in the video mentioned at 8:11 - 9:05. Stan had teeth growing out from beneath his teeth, thus pushing them out further.
>>5099302That is true, so it definitely could’ve been possible that *if* T.Rex did have lips a various number of teeth could’ve been sticking out as they were getting replaced then. But I still don’t think I’m convinced that T.Rex could close its jaws so tightly to the point lips couldn’t have room to exist.
>>5099358>I still don’t think I’m convinced that T.Rex could close its jaws so tightly to the point lips couldn’t have room to exist.almost half of known T. rex teeth have wear all along the sides where the top and bottom teeth rubbed against each other. there wasn't any space between the teeth for lips. The teeth touched rubbed against each other
>>5099359>The teeth touched rubbed against each otherDo you think that was painful?
>>5099359in the video Peter says the exact opposite, if the teeth rubbed together then we would see wear inside of the maxillary and outside of the dentary but instead he shows the teeth have the opposite condition where the maxillary has wear on the outside and the dentary has wear on the inside. he argues that this from tooth on bone wear that comes from the dentary teeth coming into contact with the upper palate but the way I see it is that this tooth wear is simply from feeding.
>>5099369They were big dinos
>>5099358>>5099143What about a middle ground approach where they had partial lips that still left the lower half of the teeth visible (pic related). One of the main reasons I doubt the validity of lips is the amount of face biting these animals engaged in. We know that T Rex engaged in intra species fighting very often with the face being the main target. Lips just seem like a liability that would leave an infected wound if bitten off
>>5099424>middle ground approachSo, Jurassic Park was right all along?
>>5099476There is a video of a paleontologist talking about this. He explains how design wise, the JP T Rex is fairly accurate, unlike the velociraptors and the dilophosaurus.https://youtu.be/XyKbB73HExE?si=3k-f0__zU67nP3Bthttps://youtu.be/2EecNnBbgXA?si=8LukIsbFs6nqvJr5
>>5099546For the trillionth time, the Jurassic Park compies, dilophosaurus, and velociraptors are intentionally inaccurate. They knew what they were doing. Both Crichton and Spielberg knew what they were doing. It's not an accident, it's not ignorance. It serves a narrative point. The entire moral of Jurassic Park is that mankind does not know what to expect from Nature and is not in control of it. It's also why the carnotaurus can change colors like a squid.
>>5099574None of those videos are talking about the compies, dilophosaurus or velociraptors
>>5099574Are the compies really inaccurate for the time? they look pretty standard 90's tiny theropods
>>5099574Crichton's animals are a bit puzzling in a few places, though. For example he based the idea of Deinonychus being a species of Velociraptor on Gregory S. Paul, when Paul was drawing feathered raptors at the time. I think it would have better served the narrative point of nature being unexpected to have made the raptors feathered.Also, both the T. rex and Velociraptors in his novel have forked tongues like lizards; the raptors flick theirs to taste the air on two occasions.
>>5099608To be fair to him, feathered raptors were only a suggestion back then
>>5099609They were less of a suggestion than Deinonychus' genus being changed to Velociraptor, yet Crichton still went with that.
>>5098966>using Varanids as a comparison is bad because they’re so distantly related>here are some examples of mammals with exposed teeth to support our ideaHoly fuck the retardation. Paleontologists really are manchildren with the same style of biases as paleoschizo
>>5099613The mammals were used to show that exposed teeth don't get damaged.
>>5099618They do get damaged though. Also shit like elephants have ivory which is more pliable and less likely to break or crack than. The argument that Varanids are a bad comparison because they’re unrelated is even more retarded because it’s not based on phylogenetic distance to begin with, it’s a physiological comparison
>>5099618>exposed teeth don't get damagedThey do. That’s why most mammal tusks grow continuously. Elephants are a particularly good example because their favoured tusk gets worm down more
>>5099600They have a poisonous bite and it's an important part of the narrative of scientists fucking around and finding out in the book. Same with the Dilophosaurus spitting. The fucking raptors could bite through steel. It's kind of amazing how often this retarded "conversation" (reddit attention seeking behavior) comes up from people who've never read nor understand the book.>>5099608Crichton and likely Spielberg also realized that feathers are for trannies and since they wanted the majority of movie-goers to give them money, instead of an insanely vocal clique of outsourced glowniggers, they made the right call.Dinosaurs don't have feathers. Hoaxes aren't Dinosaurs and neither are birds.>>5099620And here's where this "debate" always breaks down and all the retards ignorant of comparative anatomy and paleontology (most "people", including most "paleontologists") expose themselves for the fucking incompetent ignoramuses they are. Elephants without enamel on their tusks is a new evolutionary trait and for some reason seems to track with the cooling of the planet at the beginning of the Pleistocene Ice Age. Multiple Elephant families had enameled tusks just fine for millions of years.
>>5099627That's probably because people usually talk about the movie (where the only jarring one is the dilo)
>>5099628Just ignore him; it's paleoschizo.
>Elephants without enamel on their tusks is a new evolutionary trait and for some reason seems to track with the cooling of the planet at the beginning of the Pleistocene Ice AgeWhat? Proboscideans had dentine coated tusks by at least the Oligocene
>>5098966Shocked it took you this long to make a thread about this video. I’m disappointed>>5099636>paleoschizo fails to do a 2 minute google searchWhat else did you expect from him
>>5099637I'm actually not paleoschizo; I was waiting expecting him to be the one to make a thread about this video, too, but I suppose Larson's arguments are too scientifically sound and not schizophrenic enough for him to use. Or maybe it didn't show up in his YouTube recommendations.
>>5099574>It serves a narrative point. The entire moral of Jurassic Park is that mankind does not know what to expect from Nature and is not in control of it.It's also worth noting that the dinosauars in JP aren't considered authentic even within the story itself, on account of being chimeras made with DNA from various other organisms: i've never watched the film so don't know if this scene made it in, but in the book this is explicitly pointed out, iirc with Wu proposing to Hammond that since the dinosaurs aren't perfectly "realistic" anyway, the park could be more commercially successful if they're modified to better reflect normies' preconceptions of what the dinosaurs will be like.
>>5099623>They do. That’s why most mammal tusks grow continuously.Dinosaurs continuously replace their teeth.Also, the issue isn't just wear but that their teeth will become unusable or something due to the damage.
>>5099635I have to say it's very funny how he went on an autistic rant about Jurassic Park just because someone mentioned some aspects of the T. rex are correct
>>5099678How the fuck have you not watched the movie? are you 10?
>>5098966Yeah I’m not convinced at all. Like what was said before this reeks of the same kind of bias as Horner really wanting T. rex to be a scavenger or Longrich’s whale mosasaurs. Paleontologists are human and usually autistic so it’s not a surprise they get attached to an idea
>>5099627>Elephants without enamel on their tusks is a new evolutionary traitIvory tusks were a thing before true elephants even existed
>>5099699I never got to watch many movies growing up, and as an adult I never really got around to doing much catching up
I think that people are desperate to give dinosaurs lips because there's a modern trend of trying to actively remove anything that might make them look "to cool" because it makes them feel more intelligent to do so and that somehow making them look lame means you're viewing them as real animals instead of movie monsters because you're just so enlightened
>>5099734>stop demasculating my dead lizards
>>5099735I also dislike that I can't make this argument without sounding like a GRRRR FEATHERS ARE WOKE retardYou can swing too far in both directions
>>5099734The whole movie monster thing is blown way out of proportion to begin with
>>5099737you're just so enlightenedyou sit a fence as though it were a penis
>>5099746Why do retards here call being reasonable fencesitting?
>>5099751people are fed a nonstop deluge of media telling you that you are either on the right team or the wrong team, to the point of demonizing the middle groundretards are much more affected by propaganda
>>5099709Horner's scavenger T. rex was a piss take and I applaud him for it. Tyrannosaurus is for trannies. It's right in the name.
>>5099711Go ahead and name them please.
>>5099777It seems he has experience with denying that someone's a predator
>>5099778Gomphotheres and Deinotheres
>>5099627>Crichton and likely Spielberg also realized that feathers are for trannies and since they wanted the majority of movie-goers to give them money, instead of an insanely vocal clique of outsourced glowniggersYeah, big issue back in the 90s.
>>5099777>Tyrannosaurus is for tranniesTrips confirm. Theropodlets mogged once again. BVLL anky reigns supreme
>>5098966>source>some guy on JewtubeI will simply believe the opposite.
>>5099851P-schiddy was an egg in his infant mother's ovary when that movie came out. His grandparents saw JP in theaters.he has no idea what america was like in the 1990's because he wasn't alive.
>>5098984Cloaca lips?
>>5099897You haven't seen the recent papers showing that T-Rexes had a juicy pink pussy that they used to drain prey before eating it?
