Important prey of Jaguars: A Friend named Jacabo Friera Acebal who worked a few years in Hato El Frio in the Venezuelan Llanos, he visited el Pantanal recently I asked  him the comparison of the size of Caiman yacaré from el Pantanal with Caiman crocodilus from Venezuelan Llanos. He told me that he saw a good number of yacares 2,5 meters or larger and the biggest one he  saw he estimates measured 3 meters long he took a picture of the biggest one attached, very few caiman crocodilus from los llanos grow over 2,40 meters long.
@yacobnaturaleza

That's exactly what Paulo and I thought as well. The largest we saw we estimated to be around 10 feet.
They are also very dense and completely armoured and they seem to be adapting more armor right behind their heads that is where they even have bigger scales.
The best way to tell their girth is actually by their tales, the thicker the tail the heavier the caiman according to Paulo.

They are everywhere btw, my favorite shots of them are when you boat past the dense floating foliage and you see them sitting deep inside,  it looks so cool.

Yet, jaguars simply bite through their armour just like how jaguars crush the shells of turtles.

They sure do, they're quite an impressive cat.

Los Llanos of Venezuela had a big number of Caiman crocodilus but far from the numbers of Caiman yacare in el Pantanal, I saw many of them I estimate the largest one attached in the first picture measured under 2,50 meters long the largest captured and measured by us was 2,05 meters long and weighted 44 kilograms

The late Jose Ayarzaguena Zanz who worked in the Venezuelan Llanos for 30 years did a research with Caiman crocodilus in 1983, largest male measured 2,31 meters long and heaviest weighted 58 kilograms Largest female measured 1,61 mts long and heaviest 20 kg. He captured 324 animals.

I'd say that Pantanal Caiman weigh upwards of 100kg at their max put that is purely speculation based off my visual estimate of large ones.
They are hard to get an accurate weight on since I'm far less familiar with Croc's.

Totally agree with you @Pckts

Honestly, I doubt a jaguar can kill huge crocs and even crocs which are larger than average. Leopards, however, have killed small crocordiles. Therefore, the more powerful jaguar could kill at least caiman size crocs.

BLACK CAIMAN AND JAGUAR

a - Interaction

Not so long ago, researchers found a black caiman of 380 cm. killed by a jaguar. The article, with a photograph, is on the internet, but I also saw it at Carnivora. I also remember an article (with a photograph) of a breeding, and therefore adult, female killed by a jaguar. Both the male and the female were not eaten. 

The conclusion is that jaguars are capable of killing adult female black caimans and quite large males, but incidents of this nature are very rare. Jaguars no doubt have been killed by black caimans as well.

b - Video  

Here's an interesting video on Melanosuchus niger:

c - Article

Here's an article written by J.B. Thorbjarnarson. He also featured in the video:

d - Black caimans and humans

When I was in French Guyana, I saw a large black caiman near a river. The head seemed broader and heavier than in other caimans and crocs of similar length.

They told me to be wary. The stories I heard have some foundation. Here's a report (2018) about a man attacked by a 5-meter black caiman in his canoe when he was fishing. He was saved by his wife:

A child in Brazil was not so lucky. The attack happened in 2010. The report is from 2011:

https://www.wemjournal.org/article/S1080-6032(10)00374-1/fulltext

e - Size 

I saw a few documentaries about the black caiman in French Guyana. Same region I visited. In one of them, they came very close to the boat of the crew. According to the film maker, large males exceeded 20 feet. If we add they have relatively large and massive skulls, the conclusion is adult males of Melanosuchus niger are not on the menu of jaguars. Adult jaguars, however, could be on the list of the black caiman.

The former owner of this skull most probably was about 14 feet in length. Too large for any jaguar, I think:
