Smilodon populator v Brontornis burmeisteri
Smilodon populator
Smilodon, often called a saber-toothed cat or wrongly a saber-toothed tiger, is an extinct genus of machairodonts. This saber-toothed cat was endemic to North America and South America, living from near the beginning through the very end of the Pleistocene epoch (2.5 mya—10,000 years ago). Smilodon populator ("Smilodon the Devastator"), 1 million-10,000 years ago; occurred in the eastern parts of South America and was the largest species of all machairodonts. It was much larger than its cousins, S. fatalis and S. gracilis, possessing a massive chest and front legs, and is the largest known variety of saber-toothed cat. It was more than 1.40 m (55 in) high at the shoulder, 2.6 m (100 in) long on average and had a 30 cm (12 in) tail. Smilodon populator was substantially heavier and larger than any extant felid, with a body mass range of 220–360 kg. Particularly large specimens of S. populator almost certainly exceeded 400 kg in body mass. Its upper canines reached 30 cm (12 in) and protruded up to 17 cm (6.7 in) out of the upper jaw. Genetic evidence suggests that Smilodon populator and other members of the genus diverged from the main lineage of modern cats (subfamily Felinae) around 14-18 million years ago.

Brontornis burmeisteri

Brontornis is an extinct genus of giant flightless terror birds that lived in Patagonia, Argentina. The only species currently accepted as valid is B. burmeisteri. It has traditionally been placed in the family Phorusrhacidae, nicknamed "terror birds" for their large size and predatory lifestyle, more specifically the subfamily Brontornithinae, which contains the extremely large and heavy-set phorusrhacids. Fossils of the terror bird have been found in the Santa Cruz and Monte León Formations in Argentina. It is known from bones, mainly of the legs and feet but also portions of some skulls and backbone, found in several localities of Santa Cruz Province. B. burmeisteri was the second-tallest species of phorusrhacid, with a height of around 2.8 m (9.2 ft) and the heaviest species of phorusrhacid with an estimated weight of 350–400 kg (770–880 lb) (Alvarenga & Höfling, 2003), making it the third-heaviest bird ever according to current knowledge (after Aepyornis maximus and Dromornis stirtoni), and the most massive land predator of its time and place. Due to its bulk, it probably had a lifestyle between an ambush predator and one that actively chased prey, pouncing on the latter from a hideout and bringing it down by sheer force of attack after a short chase. In attacking prey (but probably not necessarily in a defensive situation, as it was too slow-moving) it most likely was the dominant carnivore of Miocene Patagonia, being able to kill even large animals such as the elephant-like Astrapotherium and in the predatory role being on par with a pack of Thylacosmilus (metatherian sabre-tooth). It coexisted with some slightly smaller and more active phorusrhacids like Phorusrhacos, but apparently became extinct before the appearance of the immense Argentavis, the largest flying bird ever.

It can go either way. The brontornis heavy bill and strong feet can cause a lot of damage making it a formidable foe. The smilodon will win if it manages to pass these weapons, leap on its back, and bite its neck.

brontornis is impressive but smilodon was capable to hunt more larger then himself and know to hunt bison, Macrauchenia, Megatherium,Lestodon. I dont think brontornis is not a big deal. From ambush attach it make more easier.
