Really interesting size comparison. Here some information that I've find
Adult black bears are usually between 1.4 and 2 meters long with a height at the withers between 1 and 1.3 meters. Body weight can vary significantly depending on the subspecies, sex, age, and time of year. Females can weigh from 40 to 180 kg, while the weight of males varies between 70 and 280 kg.

The Cougar: Height: 60 - 90 cm (Adult, At the shoulder) and Length: Male: 2.4 m (Adult), Female: 2 m (Adult)
Here in Argentina usually people finds cougars. They're really very good hunters and often kills cows, sheep. Those animals are the livestock of the people who live in Patagonia

Have you visited Patagonia?

Not yet. I visited some others places of Argentina,But I never I've visited the Patagonia. 
Theres are variety of animals. Definitely an awesome place which someday I would like to go.

Its on my list as well, I hear it's beautiful. Reply

The Patagonia it's really awesome. I have seen a lot of documentary from that area. The Cougars are truly awesome felines their skills to hunt and how they do the impossible to survive and adapt to everything. The best of Argentina are the provinces and small towns. I was fortunate to visit at least more than 5 small towns and fields in consecutive years. A excellent experience! 
The day you visit there you will not regret Reply

Contrary to popular misconceptions, temperate South American cougars (i.e. not from the southern range of the Andes) are perfectly capable of attaining large sizes that rival those of their North American and Patagonian counterparts. What determines the size of cougars has less to do with the temperature they live in, and more to do with their access to abundant prey. This is why despite being closer to the equator, Llanos and Pantanal cougars will present large sizes as well.

The jaguar in this video appears to be 107 kg Tupã, it's likely that the cougar weighed around or more than 80 kg, roughly estimating. Reply

To display an interesting case of what seems to be convergent evolution, I put together some size comparisons. Here are the preserved/extrapolated skull and forelimb elements of an equivalently sized Megalosaurus and Yutyrannus, specimens BMNH 36585 and ZCDM V5001 respectively. Note that both specimens would be about 447 kg in life.

We can see that both of these animals display a number of similar features which suggests they may have had similar lifestyles. Both have quite large heads for their size (80 and 85.2 cm) that would have been quite wide and robust, and both display rather large and strong forearms for their size as well (humerus lengths 34.1 and 35.6 cm respectively), tipped with long, sharp claws, proportionally similar to many carnivorans that rely largely on their forearms for prey capture.

Another potentially interesting feature is the fact that both Megalosaurus and Yutyrannus are markedly different from their more famous relatives, the giant spinosaurids and tyrannosaurids, with their combinations of large arms and massive, robust skulls. Like Yutyrannus, tyrannosaurids would have retained a massive, strong skull, but would have had short, useless forearms. Likewise, spinosaurids shared large and powerful clawed forearms with Megalosaurus, but did not have a robust and massive skull as it did, instead having skulls much more similar to modern fish-eating crocodilians.

I think that from these comparisons, it can be concluded that both of these species would have had multiple very efficient to attack prey (mauling it with their deadly bites while simultaneously controlling and clawing it with their large clawed forearms), that because both evolved these to be very similar proportionally their hunting strategy must have been rather similar in some way, and interestingly, they both differ from relatives in similar ways due to the possession of these features.

I thought that this would be interesting as herbivores are seldomly represented in size comparisons; my version of:

Alaskan Moose (210cm at the shoulders) - Wood Bison (183cm at the shoulders)

This photo is so good to see size difference, that I put it here too.
