The Black Jaguar's Placement on the Geological Time Scale: Cenozoic EraQuaternary PeriodHolocene Epoch

A mitochondrial DNA study from fossils in Northern South America showed that the modern Jaguar species arose around 280,000-510,000 years ago in the Pleistocene Epoch.

Black Jaguars live in Asia, Africa, and parts of central South America. They can be found mostly in tropical and deciduous forests, but they can also inhabit rougher turrain such as grasslands, marshes and swamps, deserts and mountains.

You might be wondering why we didn’t do our project on black panthers. There are actually no such thing as black panthers, but rather tawny (dark brown) colored jaguars or leopards. The word "Panther" describes big cats such as jaguars, leopards, and mountain lions.

Characteristics of Jaguars:Jaguars are one of the largest cats in the world. They can have a body length of 112-185cm. They weigh from 126-249 lbs. Even though they are the heaviest cats, they are able to climb well. They are also known for their powerful bites out of all the big cats. Jaguars are usually dark brown or black and because of their furs, it makes it harder to notice them during the night while they're hunting food. This means that prey would make it harder for them to see any jaguars coming.

Major Geologic Events (2)There are some significant occurrences during the Eocene Epoch. In the early Eocene epoch it is thought that the highest mean annual temperatures of the entire Cenozoic era occurred with temperatures of about 30° C; which is due to the thermal maximum that started towered the end of the Paleocene epoch. In the middle Eocene another significant occurrences happened, it was the separation of Antarctica and Australia which created a deep water passage between those two continents, creating the circum-Antarctic Current. This changed oceanic circulation patterns and global heat transport, resulting in a global cooling event observed at the end of the Eocene.

Dormaalocyon latouri is believed to be one of the earliest ancestors of the jaguar. It was discovered in January of 2014. Although there is no exact genetic evidence that the Dormaalocyon latouri and jaguar share the same ancestry, if you compare the scientific classification of both the animals you will see huge similarities.

Major Geologic Events The Dormaalocyon latouri is believed to be the first ancestor of the panther; paleontologists estimate that he was found during the Paleocene and Eocene periods and these are some of the major event that occurred during that time. The Paleocene Epoch had two major events in Earth's history. It started with the mass extinction event at the end of the Cretaceous. This was a time marked by the demise of non-avian dinosaurs and giant marine reptiles. The other major change was at the end of the Paleocene epoch it was the Paleocene- Eocene Thermal Maximum. This was a geologically brief (~0.2 million year) interval characterized by extreme changes in climate and the carbon cycling.

Evolution Scientists were able to determine that the Dormaalocyon latouri was living during the Paleocene and Eocene periods because of its ankle bone fossils that reveal that the Dormaalocyon scampered through the trees in what was then a humid forest. So it is logical to think that Dormaalocyon lived during the Paleocene and Eocene periods because during that time the Thermal maximum accord happened and many humid forests appeared.

Food Source:The jaguar's trophic level is tertiary. They are consumers and are carnivorous animals. Many jaguars are predators because they are feared and powerful to many organisms. Jaguars usually hunt during the night. This means that they are nocturnal. Many would get their prey by stalking or abushing them from the ground. Depending on where they live, many will eat different kinds of organisms. Many will eat seer, warthogs, wild boar, tapir, and antelopes. However when food is scarce, jaguars would eat birds and rabbits.
