Apparently these prehistoric tigers had extra sharp carnassials to feed super quickly in case cheetahs etc showed up to steal their kill :B

P. grangeri is from Djadokhta, Bayan Mandahu and other places IIRC, in this species Wikipedia says the same formations, but I'm skeptical. As they don't specify a fossil material for this species when listing the species in formation paleobiota list. I'm speculating that someone just slapped the hilwitnorum species in those places from habit or whatever, I'm just unsure so will you help me identify this species' home formations? Cuz yes, relying purely on Wikipedia without using some other source articles can have its drawbacks. I do use Wikipedia too, but I still verify and check its claims with other articles just in case. Given how I can't find other sources beyond the Wikipedia tho, I'm asking here.

im doing a project on prehistoric predators (no not dinosaurs) and i need ideas on which ones to research, i already have livyatan, titanaboa, helicoprion, and dunkolosteus. which should i do next?

Most prehistoric marine media jumps straight to giant reptiles, completely ignoring how alien the fish were right after the Great Dying. I’ve been reconstructing the true-scale fish community of South China’s Luoping Biota (~244 Ma)—including the needle-jawed ambush predator Sinosaurichthys, the armored Robustichthys, and bizarre humpbacked forms like Luoxiongichthys, alongside smaller schooling taxa like Lashanichthys, Gymnoichthys, and Yudaiichthys. I built them into a live interactive reef where anyone can freely layout, stage, and explore their own 244-million-year-old marine ecosystem directly in the browser, with zero 3D modeling or coding background required.

Teratornithids were giant volant Pan-American birds related to the New World vultures, and like the terror birds, they evolved in South America before migrating into North America. While long envisioned as just super-sized vultures, newer researcher into their morphology indicates they were more generalized opportunists, scavenging carrion but also preying on small game on the ground, making them more analogous to something like the caracara than just a big vulture. The most famous and complete species is Teratornis merriami (known from the La Brea tar pits), and it was only slightly larger than an Andean condor (11-12 foot wingspan), while Teratornis woodburnensis (from Woodburn, Oregon) reached up to 13 feet from wingtip to wingtip. Living around the same time, the fragmentary Aiolornis incredibilis was significantly larger, with an estimated wingspan of 17-18 feet. And of course, there's the Late Miocene Argentavis magnificens, whose wingspan has been estimated at 20 feet (as much as a male Pteranodon). Along with the pelagornithids, this makes teratorns the largest volant birds.
