Here’s a drawing I did of a Livyatan back in 2021 that I completed tonight. See earlier 2021 drawing.

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.

MEGANTEREON SP.
The Dirk-toothed Megantereon is usually associated with Pliocene and middle Pleistocene faunal assemblages. A jaw found in the Chadian site of Toros Menalla, dates the origin of Megantereon back to Late Miocene, around 7 Mya.

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!

As is mentioned, sedimentology hints the Lanzhou basin of late Miocene were lushly forested. And both Y. yongdengensis(Fig.1) and faie(Fig.2) were probably forest dwellers that preferred small to medium game.
They were probably very similar to modern Cougars or Golden Cats.6/

Auqatic sloth, marine gharials, weird and wonderful whales, penguins and giant sea birds, turtles and giant sharks. All that is part of the Pisco formation. A Miocene slice of time that deserves more attention.
