First is the mandible shape-The Jaguar has a concaved mandible while the Leopard has a flat/almost convcexed one.

The Nasal Projection and bone above the orbital is raised on the Jaguar and not the Leopard.

The height of the extreme distance of the mandible is more exaggerated on the Jaguar as well. 

The zygomatic arch is also more arched in the Jaguar as well as a more exaggerated sagital crest.

The distance from the  auditory bullae to the back of the mandible is much closer in the Jaguar than the leopard due to its massive size and slope of the crest.

Again, it's exaggerated because of the difference in size. It would be less exaggerated if the skulls would be somewhat equal in size. The most prominent difference between the skulls is the forehead and the jaguar skull being proportionally wider whereas the leopard skull will be proportionally longer.

Yes they completely overlap as is seen in this study as well:

Your initial post was focusing on the leopard and jaguars having 'completely different' skulls. I pointed out that the book simply used the leopard to compare as they are the two cats that can have similar skull dimensions. Still the book only implied that jaguars have wider skulls proportionally. Not that the skull is completely different compared to a leopard skull.

When was I triggered and when did someone compared a snow leopard to a common leopard? Have I missed something or are you again bringing up debates on a different forum - Carnivora.net?

The tigress skull was actually first acknowledged to be a leopard skull, a record one that is. Also it had nothing to do with the fur but simply because of the fact that the size of the animal and its skull layed in the overlapping of large male leopards and small tigresses. Here's another case where they made a mistake in identifying the animal; alleged tiger pug marks turned out to be leopard ones:

"Vishal Thakor, who has worked on human wildlife conflict mitigation said that people often mistake pug marks of leopards for that of a tiger. "This is because sometimes leopards can also grow to a huge size. Unless the pugmarks are in wet earth, it is also difficult to get its dimensions from a mere picture. Several measurements need to be taken before one can be sure whom the pug marks belong to," said Thakor." - https://www.dnaindia.com/ahmedabad/report-gujarat-tiger-pug-marks-turns-out-to-leopard-s-2729925

Second the skull its measurements were in the range of the largeest male leopard skulls (287,02 mm x 200,66 mm).

Wait so first it's false and now you do admit that they overlap although between specific populations? Not all jaguar skulls are the size of a Pantanal jaguar skull. Jaguar skulls smaller than a leopard skull can perfectly belong to an adult male jaguar. Hence why they overlap.

Still shorter than the largest leopard skull which was estimated at 297 mm long. Quite believable given the condylobasal length of 264 mm. It's narrower (186 mm) but that's understandable as jaguars have proportionally wider skulls.

I explicitly said it depends which source you consider reliable. Those are the two widest skulls each from a different source. We can stick to scientific sources only, that's fine as I prefer those as well. A skull width 191 mm is marginally narrower than the average skull width for Pantanal male jaguars. So a Pantanal male below-average shall have a narrower skull than that Persian leopard skull. That's what one would call an overlap in size.

Pretty much yes. I simply disagree with the claim of jaguar skulls being completely different to leopard skulls especially since this claim is nothing more than an opinion but stated like it's a fact. Never have I ever said that the largest leopard skulls are equal in size to the largest jaguar skulls. Isn't it obvious that they overlap in dimensions and overall size? I've posted scientific data to back this up plus added photographs which clearly shows how similar they can be. This isn't a rhino skull we're comparing to a giraffe's; we're comparing two skulls from the same genus who too overlap in body size. If they overlap in body size, they certainly will overlap in skull dimensions too.

I'm not trying to win this debate/argument FYI. I think Balam and I are black and white and we're looking for the grey part to settle this. I think it would be good if more members would chime in.

@Balam 

I asked you some questions which you can expect when you post a (in my opinion) controversial claim, and you decide to reply to me with the forum policies? Like, numerous times? A bit childish to be honest.

The graph clearly shows they overlap. Even the lion overlaps with the jaguar but it's clear that it's mostly lions and tigers & leopards and jaguars who overlap. 

It doesn't matter if they're dwarfed at extremes since an overlap can occur at minimums or averages as well. You're trying everything to dismiss their overlap. From the smallest populations to the maximums of the largest populations. Whatever suits you.

Quote:Prove now that leopard skulls attain the size ranges of jaguars from the Pantanal, Llanos, or Chaco. The word "overlap" is being repeatedly used by this person as if that claim wasn't objectively wrong.

Why do you want me to specifically pick a population, especially ones that suit you? Don't you hate cherry-picking? What's wrong with populations that do completely overlap? Post skull data of Llanos and Chacoan jaguars and we'll see if they overlap. I cannot prove this when data is lacking.

I've seen this comparison long before you were around here. This photograph is unfortunately being abused because everyone who posts this, decides to not mention the measurements.

I've shown size variation in Indian leopards as one sample does not decide the size of a whole subspecies. This is the same case when comparing Pantanal jaguars to Caatinga jaguars who both live in the same country.

Persian and Arabian leopards are different subspecies unlike jaguars, who only have one subspecies. It's not exactly the equivalent. An equivalent would be Cape leopards and leopards from the provinces of Limpopo, Mpumalanga or KwaZulu-Natal in South Africa. 

Now show me the differences between those skulls I 'cherry-picked'. After all they're completely different right? Well prove it.

Quote:And I will wait on an answer for Shazam's weight, direct data is much better than guesses based on photographs.

You should've done that in the first place rather than giving a clear overestimation to back up your claim.

Quote:Again, it's exaggerated because of the difference in size. It would be less exaggerated if the skulls would be somewhat equal in size. The most prominent difference between the skulls is the forehead and the jaguar skull being proportionally wider whereas the leopard skull will be proportionally longer.

Quote:Pretty much yes. I simply disagree with the claim of jaguar skulls being completely different to leopard skulls especially since this claim is nothing more than an opinion but stated like it's a fact. Never have I ever said that the largest leopard skulls are equal in size to the largest jaguar skulls. Isn't it obvious that they overlap in dimensions and overall size? I've posted scientific data to back this up plus added photographs which clearly shows how similar they can be. This isn't a rhino skull we're comparing to a giraffe's; we're comparing two skulls from the same genus who too overlap in body size. If they overlap in body size, they certainly will overlap in skull dimensions too.

Quote:Again I'm not seeing two entirely different skulls, just a bigger version of the other

Quote:I've seen this comparison long before you were around here. This photograph is unfortunately being abused because everyone who posts this, decides to not mention the measurements. The leopard skull is circa 245 mm whereas the jaguar skull is circa 280 mm or in other words; they're everything but similar in size.

Quote:You said that they overlapped "completely", now you are twisting Rishi's point to paint yourself as the misunderstood one. You were very clear from the beginning and very wrong. If they overlapped completely then the largest leopards would have to match the largest jaguars in dimensions and they do not. You made the claim, not mem and unsurprisingly you've failed to prove or back up any of these points.

Quote:There is nothing childish about highlight forum violations when you repeatedly engage in poor reasoning based on preconceived notions and then double down on them repeatedly, even when they are verifiably false and when the data has been shown to you multiple times (deflection fallacy). 

Quote:What part of the entire dataset available showcasing that the gap between jaguars and leopards is just as big are you not getting? The largest jaguar skulls (not even belonging to the heaviest specimens) on public record far surpass the largest leopard skulls and they do so in averages as well. Do you think that posting a graph and taking it out of context is going to all of a sudden offset the rest of the available data publicized?

Quote:Strawman #2, I've never once said this and once again this breaks the forum rules. Mods?

Quote:Read what my post says: Prove now that leopard skulls attain the size ranges of jaguars from the Pantanal, Llanos, or Chaco. A range implies a distribution between the smallest to the largest, because it was you who made the claim that leopards and jaguars "completely overlapped" in dimensions, the burden of proof falls on you to prove that they match the largest measurements for jaguars from these populations (a complete overlap). Once again mods, this a circular argument in violation of the forum policies with the dismissal of crucial data.

Quote:Another fallacy, appeal to authority, what does you having had seen this before has anything to do with points being discussed? And how is it being "abused"? What do measurements have anything to do with this since we're comparing skull proportions?. If the jaguar skull were to be scaled down to the leopard's size based on length, the differences in anotomy would remain the same. One more thing, the skull length of the Central African leopard almost perfectly matches the average for this population, while the skull of the Bolivian jaguar (likely a Chacoan or Yungas specimen) falls well short of the average size of a Pantanal or Llanos jaguar skulls and yet it still dwarfs the leopard skull. Interestingly how your claims of Central African leopards attainting the dimensions of Pantanal jaguars fall apart, especially when we take into consideration that an average-sized skull from the Pantanal of 290mm in length and 195 mm in width would be even larger against that average-sized Central African specimen. Comparing one to two outliers against a population average (and still failing to meet the dimensions of said average) doesn't symbolize an overlap, but I digress.

Quote:That is not how it works, jaguars are classified as a monophyletic species but that doesn't mean that genetic differences between populations do not exist. And your comparison is completely flawed because national boundaries have no relation to the things that matter in this context which are regional differences based on ecological factors. 

Caatinga jaguars are a dwarfed population because they live in environments with little to no prey to the point that some of the studied specimens from this region have died from starvation @Dark Jaguar knows all about this. The Caatinga environment is completely different from the Pantanal and is separated by a vast savannah known as the Cerrado. These two populations are as different as the Arabian and Persian leopards or Sundarbans and Kaziranga tigers, and I don't know why all of a sudden you're such a puritan when it comes to taxonomical orders when you've complained in the past about how African leopards shouldn't all be lumped into one single subspecies.

Quote:Ultimately you still haven't proven that:

1. Jaguar and leopard skull completely overlap in size. (keyword that's being repeatedly ignored in this discussion: completely)
2. There are minor differences in their skull morphology. (I expect a dissection of the main skull parts from you in this regard and why they are similar)

Quote:As I said in the previous post I'm not going to continue going back and forth until this person brings forward sound data to back his claims up instead of lengthy word-salads that have nothing to do with what's being discussed and as shown multiple times are in violation of the forum policies.

Quote:Another perfect example, ignore the size and notice the morphological differences, it wouldn't matter if you scaled the Leopard up the Jaguar down, they will never look like two Skulls that came from the same species to anyone with knowledge on the subject.

They overlap completely since leopards have surpassed the length and width of jaguar skulls. You keep sticking with the extremes but that's not how it works. For example, the Persian leopard with a skull width of 191 mm has surpassed the width of adult male jaguar skulls from the Amazon (175,9 mm). It's once again evidence of the overlapping in skull dimensions. What's not to understand?

Take a breath and look carefully at the objects (square = leopard, rhombus = jaguar). Now notice how the two figures overlap. Notice how there's a square (= leopard) ovelaps with the bigger jaguars (and even lionesses).

A range distribution between the smllest to the largest populations yet to stick with Llanos, Pantanal and Chacoan population - A.K.A. the largest ones. Why not those from Belize for example? right, because they overlap, in fact leopard surpass these meassurements. You obviously know this hence why you want the largest population for comparison.

First of all I am the one who wants to compare the skulls, but skulls that equal in dimensions. The comparison you posted is everything but equal or similar (245 mm vs 280 mm) whereas the skulls I posted looked close in size overal. Unfortunately you found this cherry-picking; not my problem. Still waiting for these major differences that makes these skulls completely different.

Caatinga jaguars are a dwarfed population because they live in environments with little to no prey... What do you think Arabian leopards are? Or Cape leopards? You really think this rule applies to jaguars only do you? At least they're from the same species unlike Arabian and Persian leopards.
