I refuse to believe therizinosaurus claws were for just display, its just utterly unreasonable, they are hard structures, and unlike antlers, they most definitely were not shed. It simply is waaay too much investment into a nothing trait.

[@daciantalker]

16:05 If we used this type of measurement on Megalodon then wouldn’t that dramatically decrease the total length or mass of the creature? Feel free to correct me as it just got to my head

[@jacobcox4565]

I don't think that technique of measuring applies to Megalodon because we don't have a complete skull. The only things we have are the jaws and teeth. The size was estimated by looking at the tooth to body size ratio of Great White Sharks and applying that to Megalodon teeth.

[@tjarkschweizer]

We have no clue where exactly the orbits and gills of megalodon were. So the technique is useless.

I still believe that therizinosaurus was able to use its claws for defense or intimidation. Otherwise it would have been fodder for animals like tarbosaurus, and not have succeeded in its environment. Because fossilization is so rare, an animal that isn't successful is less likely to have any individuals that fossilized. Paleontology is constantly changing, and this study itself may be disproved in the future.

[@S1ayer585.]

Exactly! Even if it’s proven that therizinosaurus and other sub species didn’t use their claws for defense, it only makes therizinosaurus look weird.

[@vividsky1669]

If you still do not like the shape of the new Dunkleo, Dinichthys and Gorgonichthys are similar sized close relatives of a similar size

Haber. Las garras de Thery no eran de adamantio pero tampoco de cristal y es más. Los Therys poseían mucha fuerza en los brazos indicando hací que los utilizaba para algo. En el tema de la alimentación podían haberle servido pará alcanzar alguna hoja que se le escapase (no hacé falta romper la rama) y en el tema de la defensa hubieran sido principalmente disuasorias pero si el depredador sigue insistiendo pués se podría llevar una ostia muy dolorosa para hací alejarlo. Pero si aún con ésas sigue pués hay el Thery se defenderá pegándole empujones, embestidas y alguna hostia que pueda.

[@ThemagpieBird734]

Then what were the claws used for? If it was used for display why didn’t theri I just evolve feathers?

Feathers are very rare to be preserved, it's very likely that they did have long display feathers on their arms in addition to their long claws, but only the claws got fossilized.

[@Slomurr]

If it was true that Theri's claws were weak, then perhaps they could of also aided in "these aren't actually dangerous, but they look hella dangerous and just imagine if these went up you ass." Sort of deal. However, I do find it bizarre to believe that they were physically useless. If they were just decore, what would be the evolutionary point for it to look dangerous but isn't? I think the most likely scenario would be they could've been used to harm smaller threats in some way, display, tearing leaves off tall branched, bring tall or far away branches closer, like an all of the above. But if they were completely useless, my best explanation would be that due to it's evolution of a longer neck, large size, etc, over time the need for claws became less of an evolutionary priority. Perhaps of they weren't cut "short", It's evolutionary line would've eventually cut all ties with the Freddy Krueger claws.

[@lectroeel6290]

Exactly. I still doubt they were completely useless and likely could be used for defense in some way still. Probably for intimidation and the occasional jab at a predator.

[@geoffzuo9831]

Late but have you seen Rick's review of prehistoric planet? His point with carnotaurus is that what may seem silly to a human likely wouldn't be for many other species. The opposite likely goes too. I mean, bighorn sheep have mean looking bashers on their heads but are horrendous at using them on anything other than competing males. Even then, the sheep at least have structurally sound features, while theri's claws would break even if it got a swipe off. Sure it could probably fight off relatively small threats with them, but that goes for basically every dinosaur excluding derived tyrannosaurines and abeliosaurs.

[@lectroeel6290]

@@geoffzuo9831 yes but no one is saying theri's claws look silly. We're saying that because fossilization is so rare, only animals with high populations are likely to have some individuals that end up fossilized. If theri couldn't defend, run, or hide from predators like tarbosaurus at all, how did it fossilize?

[@geoffzuo9831]

@@lectroeel6290 Environment or some other thing. Take porcupines/skunks and caprines (goats) as examples. None are especially good at outrunning predators. Porcupines and skunks defend themselves with weapons that wouldn't ever fossilize, while goats stay on cliffs to incur the risk of a carnivore falling to its death. Not saying that therizinosaurus had anything specifically, but the science says that its claws can't be used to fight. To me at least, it makes more sense to speculate about things that there is no evidence for than to think about a theory that has been rigorously disproven.

[@lectroeel6290]

@@geoffzuo9831 it hasn't been rigorously disproven. Almost nothing in paleontology is set in stone. Have you seen the newest papers for example? They are arguing in favor of nanotyrannus being a valid genus and have some evidence. What you brought up is plausible, but I still doubt they were completely useless.

Wait, the example for the formula has the appearances of the fish ignored the nuances. Those short faced fishes have a top water jaw build, meaning facing upwards, this is the weakest point. However, from what is seen, those examples, including the not included like piranha and pacu are sleek and thin widewise. Whilst the dunkleosteus have far ticker girth akin of those boa and python like build (or eel-like, if you will). There should be a new estimation based on the eye to snout distance with the nuances of the thickness and width of the fish as that Nuances are ignored, and eels seems generally to have a thicker girth, lengthy body with shorter ratio from eyes to snout. I hope this doesn't go like the spinosaurus aquatic or semi aquatic shenanigans last time.

[@dynojackal1911]

Therizinosaurus's claws are longer, less sharply curved, and more laterally flattened than any of its relatives. Although their shape matches a real scythe blade, bone is more brittle and less flexible than steel. Display is the only viable option. The body-shape used for the new Dunkleosteus looks ungainly and not something a top predator would have.
