The Cenozoic era began about 65 million years ago and continues into the present.
Description 2.5 million years ago during the early Pleistocene epoch in what is now Citrus County, Florida, USA, an elderly bull American mastodon (Mammut americanum) wandering the pine flatwoods alone is being ganged up on by several huge predatory birds. While the elephant-like mastodon is way too large for most predators of this ecosystem to normally attempt to hunt it, this old male is weakened from its age and is also a bit ill, walking slower and being less strong than a healthy young adult, and also has lots of old scars and wounds from many former battles. Sensing that the mastodon is weakening and nearing its life's end, some flightless carnivorous birds over 2 meters tall, Titanis walleri, have started to follow it around, occasionally getting brave enough to rush at it and injure it with their sharp beaks. After a while, a mob of the terror birds forms and they all attempt to land attacks on the mastodon, hoping to eventually tire out the huge mammal and kill it. However even in its weakened state, the bull mastodon is a powerful and dangerous target, capable of killing the birds with its kicks and tusks, and one Titanis learns this after getting slashed by a tusk. So, I recently found out the while the American mastodon is best known to have lived during the late Pleistocene in more temperate habitats, the species first evolved some time in the Pliocene and was very widespread, ranging across North America from as far north as Alaska all the way south to tropical parts of Central America like Honduras. Some Pliocene and early Pleistocene populations of the mastodon in Florida would have coexisted with Titanis, which means interactions between the two species could have occurred. Of course an adult mastodon would be too big for one Titanis to kill, but perhaps an older and sick one is a potential target for a gang of the birds? I thought this meant a possible Cenozoic version of the common paleoart trope of 'a gang of large theropods (usually an allosauroid) hunting a sauropod' which I just had to draw. While it may resemble a mammoth or elephant, the mastodons were an extinct genus (Mammut) of proboscideans in a different family from them, in fact mastodons are only as related to elephants as pigs are to cows. Several species of mastodon once lived in North America, the most widespread having been the American mastodon (M. americanum) which often reached shoulder heights of 2.3 meters (though some large males could reach shoulder heights of 2.8 meters). Judging from the makeup of mastodon fossil sites it appears that the mastodon had a similar social structure to elephants, with females and young living in herds while males leave these herds and mostly live alone after reaching adulthood. The mastodon was a browsing animal that fed on various plant matter and lived in more forested habitats whereas mammoths lived in open grassland habitats. How much fur mastodons had has long been a subject of debate: they are often depicted with long shaggy coats like mammoths, but mastodons actually had a preference for warmer habitats than mammoths so likely were less hairy or possibly even almost hairless like modern elephants. Given that the American mastodon lived all across North America for around 3 million years, its distribution encompassing areas of a wide temperature range from temperate Alaska to tropical Honduras, so it is possible that different mastodon populations had different fur extents. I chose to give this early Pleistocene Floridian mastodon only a very limited coat since it was mostly a subtropical savannah habitat there at the time. The Phorusrhacidae is an extinct family of flightless predatory birds with long legs and sharp hooked beaks, also commonly called the 'terror birds' since some larger species were 2 to 3 meters tall and dangerous apex predators. The terror birds originated in South America where they were endemic to for most of the Cenozoic, but when the Isthmus of Panama formed and connected North and South America, some of them expanded north and colonized parts of North America. By the early Pleistocene terror birds were almost extinct, with the Floridian Titanis being one of the last phorusrhacids on the planet. But even near their end these birds were powerful hunters, and standing over 2 meters tall Titanis was one of the largest, and towered over most mammalian carnivores of its ecosystem. Using its powerful beak, this animal likely pummeled its prey to death and fed mainly on ungulates, ground sloths and large rodents similar to capybaras. However, I wonder if perhaps on occasion they would form groups to mob larger prey like I drew.
