Wood ducks are so beautiful. These were in a huge group of mallards. Only ones who didn’t leave the water to beg for food when they saw me approach. (Don’t feed wild ducks) 🦆🪶 #birding

Sneak peek - how muscular was Homotherium serum, exactly? And should we return to the slope-backed look? Skeletal and soft tissue exploration coming soon (when I have some time away from my thesis!)

Large predatory mammals of Finland, drawn for the Finnish Nature Association. The existence of large predators is almost entirely up to the goodwill of humanity. Thus, it is crucial to tell people about these amazing animals, countering fear with wonder and understanding. #Sciart

Mamenchisaurid with speculative breeding "plumage" - I'm imagining these as less fluffy & more like long, floppy spines or quills that grow during the breeding season. Directly inspired by living animals #paleoart

My drawing of the basal sabretooth cat, Yoshi minor (or Metailurus parvulus). This species was about the size of a large lynx and lived in the Late Miocene, around 9 MYA. It was a leggy, small skulled animal that bore little resemblance to the big, famous sabretooths like Smilodon. #palaeoart

The basal dinosauriform Marasuchus lived about 235 million years ago. This small, gracile animal with very elongated hindlimbs is probably a pretty good approximation of what the ancestors of #dinosaurs looked like. It is unknown whether they would have had filamentous integument. #palaeoart

For #valentinesday and #FossilFriday, here's Tyrannosaurus engaging in face biting, a behaviour evidenced from numerous tooth gouges and puncture wounds in their skulls. Among living species, face biting is strongly correlated with the onset of sexual maturity, so this image is love-adjacent, sorta.

I've spent a couple of months a year out hiking/painting/sketching/photographing in the wilds of North America for over 20 years now and I have only seen a mountain lion in-person once. They are deeply private cats. "The Catbird Seat," oil on linen, 40"x35". #art #wildlifeart #cougar

I wanted to groom a lion, but with a twist. So here is cave lion! Any critique is appreciated, because I don't know that much about mammals.
