How would dromaeosaurs use their claw? Is it similar to cassowaries where they just jump and kick? Is the sickle shape effective enough to disembowel prey?
>>4466311both?animals use organs for EVERY POSSIBLE USEIncluding several uses you didn't list
post more bird and dino feet
>>4466311Probably like the red legged seriema that has the same type of toe clawhttps://www.youtube.com/watch?v=fiU59Xv2aYc
>>4466311as you know the only proven use is digging the sickle into the external carotid of protoceratopsbut in real life they probably used the sickle for disembowling, cutting throats, climbing prey, and exsanguination. Also pinning and maybe digging.
>>4466311It’s sickle shaped, designed for grappling and not exactly for slicing. Most of the damage dealt to the prey are done by the teeth and jaws, while the sickle claws are there to latch onto large prey or to grapple and pin small prey on the ground. For arboreal species like Deinonychus, it’s also used to anchor itself in place when climbing trees.That said, cats also use their claws primarily for climbing and grappling, but that doesn’t mean it can’t attack with its claws.
>>4466320>arboreal species like Deinonychushmm
>>4466320>arboreal species like Deinonychus>>4466323that gets into paleobotanydid branching trees exist then?
>>4466317Thanks for the input but it doesn't show it using its claw, just bashing it against a rock
>>4466326>did branching trees exist then?Yeah there were quite a lot, including things similar to beech or oak trees that wouldn’t look out of place in a park
>>4466576Maybe everyone has it wrong and dinosaurs just bashed shit into rocks like the bird. Maybe the claw is just for scratching its balls or picking its teeth or some shit.
>>4466311>Is the sickle shape effective enough to disembowel prey?No.Its actual use (which very likely varied between species; a small tree-dweller would use it differently from a giant plains resident) is debatable, but we know that it was awful at cutting flesh. Piercing okay, but cutting, forget it.
>>4466311Remember back when cassowaries had not any gay feathers and were viewed as murderous kicking natives?Diogenes remembers!
>>4466598>including things similar to beech or oak treesHaha. No.https://en.wikipedia.org/wiki/Fagales#Evolutionary_historyThe oldest member of the order is the flower Soepadmoa cupulata preserved in the late Turonian-Coniacianhttps://en.wikipedia.org/wiki/DeinonychusTemporal range: Early Cretaceous (Aptian to Albian)
>>4466311who wins in a fight, millions of years of evolution or a homemade plastic shield?
>>4466654>plastic shield made out of dead dinosaurs tempered by millions of years of forging into the fiery heart of the earthHow can cassuwals even compete?
>>4466606You are aware that OP posted an extant dinosaur that is proven to disemboweled large mammals with a single kick specifically to counter your milquetoast redditard science^TMfan "well akthsully" "muh normal animals not muhnsters" halfwit deboonking, right?
>>4466311If only someone could find a fossil of a dromaeosaur that died in the act of using its claws to kill prey,then these great mysteries might be answered!
>>4466576He’s making sparks to start fire so he can begin metalwork to begin making a combustible engine
>>4466815Calling Poe's Law here.
>>4466662Not that anon but can you post link to proof? All I can find is gay chickens that probably just hopped around flashing presumably colorful wing feathers in an attempt to get laid. The claw might just be for subsequent sexy time.
>>4467118>I know this is nuchan but holy fucking shit, dude.https://en.wikipedia.org/wiki/Cassowary#Attacks
>>4466662A lot of normal animals are monsters though.
>>4467133That's the point.
>>4467130But cassowaries don't have first toe sickle claws? They're totally different animals. I still think the curved claws were just used for rape.
>>4467158Dromeosaurs had varying degrees of claw curvature. Utahraptor's for example wasn't significantly straighter than cassowaries' and was proportionally too small to serve any tree climbing or pray straining purpose
>>4467130>Cassowary strikes to the abdomen are among the rarest of all, but in one case, a dog was kicked in the belly in 1995. The blow left no puncture, but severe bruising occurred. The dog later died from an apparent intestinal rupture.[46]>disembowelingI knew you were retarded, but the sheer magnitude of your retardation still leaves me in awe
>>4467078that was sarcasticismwe have a fossil of a dromaeosaurid killing its prey with its claws.
>>4466662Based post
>>4467194Older literature mentioned said the incident as "disembowelment". Also nice cherry picking when the other two recorded incidents clearly demonstrate that its talons can penetrate flesh.

>>4467344>>4467499It's hard to tell from pics, but the raptor has one arm caught in the mouth of the Protoceratops. the other hand claws are behind the frill in the neck, close to the external carotid artery, jugular vein, and tracheaOne foot is located by the prey's flank or belly, the other under the belly or perineum. all of these areas are commonly targeted by modern predators when killing prey, and wounding any of them can be lethal. Interestingly the raptor was on its side. I imagine it like a housecat that fights on its side or back, using its hands to hold its victim while it claws swiftly and repeatedly with its feet. Raptors were pretty light in weight, the only way for them to cut an animal open with the foot claws would probably be to hold it and kick, or brace themselves against the ground while kicking. The hand claws were apparently mobile and sharp enough to puncture the throat of prey, likely also delivering deadly wounds to the neck.
>>4467344>>4467499>>4467512probably the most interesting thing is that while all 4 limbs of the raptor were engaged in attacking the prey, the mouth apparently wasn't. Despite the mouth probably being a formidable weapon, the raptor appears to just be using its hands and feet while keeping the head well away from any attacks by Protoceratops. This could be attributed to movement or contraction of the neck after death (classic raptor death pose) but the way the animals were buried so fast they're caught in combat indicates the bodies didn't move after death. The raptor very likely appears exactly as it did while attempting to kill the Protoceratops. It apparently wasn't biting the animal. Rather it did the opposite and held its head well out of the way of combat.
>>4467515this isn't surprising in that most predators will protect their faces from struggling prey as much as possible. But it is a bit weird for our ideas about theropods, which often couldn't use their arms at all, probably couldn't hunt with their feet, and pretty much had to attack with their faces.raptors were a clear exception, using hands and feet to attack prey, rather than their mouths as larger theropods must have done.
>>4467344>>4467499It's easy to imagine the raptor doing a bunny kick like a cat to disembowel prey or simply shred it and let it die of exsanguination.
I think it's important to note that the sickle claw is always up, preventing it from being worn down by touching the ground. Like some modern predators that keep their claws sheathed, it needs to stay sharp. As for how effective it is for disemboweling... well I would say it depends on the size of the dromaeosaur and the prey. A giant Utahraptor kicking you with its sickle claw can't be good either way.
>>4467575>I think it's important to note that the sickle claw is always up, preventing it from being worn down by touching the ground.since the keratinous claw isn't preserved, and should be longer than the bone of the ungual, this is a mistake in thinking.It's possible, maybe even likely, that the claw was twice as long or longer in life, reaching the ground even when the bone of the toe is held up.basically, what we see isn't the claw. The claw isn't preserved. What we see is the bone of the ungual. The actual claw is unknown, and probably a lot longer than the bone we have.
>>4467575>>4467617This also means since we don't have the actual claws preserved, they may very well have been much sharper than the bones of the unguals. In most animals with keratinous claws sheathing ungual bones, they're both longer and sharper than the bones underneath.
>>4467618When the public looks at a raptorial "claw" they see it as large, sharp, and perhaps frightening.zoologists and paleontologists look at that same bone and realize the claw is actually missing. The claw was in fact probably much larger and sharper than the bones we see.
