There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.

It is known that the jaguar inhabited the pampas and even the Patagonian steppe canyons, there are also mentions in the Limay river in the Nahuel Huapi National Park, in fact the name Nahuel Huapi translates as Isla Jaguar, the sightings of jaguars in Patagonia by part del European settlers reach the Magellan Channel, unfortunately there are not so many records pertaining to the campaigns of Argentina and Chile further south of the Chubut River. According to descriptions, the jaguars in this region were quite large and the fossil record supports this idea It is estimated that the Patagonian Jaguars were larger than those of the Pantanal . The prey that the Jaguar could find in Patagonia are Rheas, Guanacos, Andean Deer, also the Deer of the Pampas that came to inhabit the north of Santa Cruz in the past and the Patagonian Mara that although it is smaller and faster than the Capybara It is still a good appetizer. Otters, Armadillos, Penguins, Land Turtles, Sea Lions and Seals could also be a good prey and it is known that collared peccaries inhabited northern Patagonia. Of course, you should share these prey with the Puma and the Culpeo Fox, although with the Puma they are generally nice and the Culpeo is not a direct competitor.

map of its possible distribution taking into account the Patagonian records.

This Text, which is in Spanish, talks about the subject and corresponds in fact to the time of the campaigns carried out by Argentina and Chile.

I have a hard time believing that prey base could produce larger Jags than the wetlands.

I'm not sure if they meant fossil records pertaining to Holocene jaguars or Pleistocene ones, we know the Pleistocene Patagonian forms were much larger than extant jaguars. Before the European settlements in Argentina and Chile there were millions of guanacos prowling the steppes of the Patagonia, I think prey like that is large enough to sustain really big cats. Guanacos extended all the way through the dry Chaco but most of the Chacoan guanacos have gone extinct, this is also another one of the reasons why Chacoan jaguars grew so big, we know they average around 95 kg today but I think they were even larger a few centuries ago
