Species: Livyatan melvillei, a large macroraptorial sperm whale from Miocene. It lived at the same era as O.megalodon, and likely occupied the similar position as apex predators.

me sweating it out on a non-marked biology activity about describing and giving examples of what evolution was doing in specific time periods (i got assigned Miocene and Devonian and i couldnt even fit everything in these screenshots lmao)

This funny lil marsupial may have once lived in the Oligocene-Miocene in Australia, but they actually have a surviving relative called the Musky Rat Kangaroo🦘

Today's warm up! A Daeodon and her calf. Semi-inspired by Forgotten Bloodlines, but mostly because I wanted to draw a softer side to everyone's favorite Terminator (Not-actually)Pigs.

Meet ADEILOSMILUS KABIR the largest African Late Miocene cat!
This scimitar-toothed felid could reach an esteemed weight of 490 kg, oversizing the largest modern tiger or lion!
It lived in Chad around 7 Mya.

Gladiusfacies, literally translating to “sword face” is a genus of ( the aptly titled ) that used to hunt in forests and woodlands in the epoch.

Ps: this is a idea and no real like this creature has been found

Annakacygna, the “ultimate bird” or short-winged swans, is a Tortonian aged flightless, sea-swan from Miocene Japan. Although the two species look similar, the Yoshii Swan is bigger than the Hajime’s Swan.

My first paper is out!
I had the pleasure of collaborating in (and illustrating) the report of a gannet (Sulidae) from the middle Miocene of Sesimbra, Portugal. Here is the coloured version of my reconstruction of the live animal.

Amphicyonids are popularly called "bear dogs" (despite being a separate family from either), and also have some traits in common with big cats, but at least one of them, the early Miocene Delotrochanter, had very hyena-like skull and jaws, being similarly adapted to crack bones!
