To see these beeflies, Australoechus sp, flying around in the Fynbos, SA, has to be 1 of my life’s highlights

Many were buzzing around Micrdon capitatus, the heady catstailbush - a rare endemic to this region. Rare because of habitat loss (land clearance) & invasive species.

Brilliant #beeflies

🖼️ Image 1 – Hypothetical reconstruction of the queen. This is what she might have looked like had she founded a colony instead of fossilizing after drowning in a water pool. The queen and her first nurse are shown tending eggs and larvae of two generations.

I recently posted a picture of a large Dorylus molestus army ant worker from Mount Kenya. Here is the same ant again, but this time in comparison to its smaller sisters. These ants are incredibly polymorphic, and the different worker types take on different tasks in the colony.

My chapter - authored with @tattersdill.bsky.social - in the new Palaeontology in Public book is "The ‘Spin’ in Spinosaurus: inventing a modern dinosaur superstar", discussing changing depictions and attitudes towards this now A-list dinosaur - read it here: uclpress.co.uk/book/palaeon... #palaeoart
A series of grey-shaded line drawings showing the changing shape of the sail-backed predatory dinosaur Spinosaurus over the last 100 years, moving through sometimes upright, sometimes spiny, sometimes T. rex-like depictions to longer-snouted, "newt-tailed" versions.

hello late #PortfolioDay !!
I'm Avi! Full time artist, doing direction (and many other things) in animation, and paleoart in my free time.
I'd be happy to work on scientific illustrations and reconstructions! I do both extant and extinct animals and i'm open for some work rn :)

A large pterosaur Bogolubovia stands on the beach, framed by the dim light of the sun due to a solar eclipse. The sky feels high and is heavily covered with clouds. A solar halo can be seen - it's getting quite cold, and it might just be this pterosaur's last winter. A digital drawing of Eohippus pair, doing the cute horse thing when they scratch and lick each others back. I thought that they could probably do that as well, like modern horses do now. They're colored light brown, with some white parts and warm shading. Almost all the head is white, they have pink noses and pink little hooves, and the main brown fur on their body is a mix of light and dark hairs, so it's quite contrasted. I actually took some inspo from hares for the colors. They stand on the dark background, a star is shining above them; next to the star are two little horses stylized sort of like cave paintings. It isn't anything i based this reconstruction of (also, it was too early for eohippus to be painted like this), just a little thing i wanted to try. A digital drawing of Psittacosaurus sibiricus. There are three of them, running to the left, on a light beige background, all in different poses to study their anatomy in motion. One of them, in the middle, is a male - colored green, with bright red on his head and quills. He's brighter than other two, females, who are colored light brown. They also have a bright spot on the face, but it's yellow and doesn't stand out as much as red on the male. I also gave them just a little, tiny bit of fuzz on the back and neck. It's barely visible and completely speculative, so take it with a grain of salt - I haven't seen it in other reconstructions. Overall, I really like how it turned out. They look silly enough to be good for me A realistic digital drawing with pterosaur embryo, 3 stages of development are shown. The left one is still tiny and barely resembles a pterosaur. It has a big and not fully developed yet eye, a thin neck and a tiny body. The second one, in the middle, starts looking like a pterosaur already. It's a little more developed, has a beak, and already has a thin membrane between the wings and legs. The yolk with blood vessels is also shown there. The last drawing on the right shows the late stage of development, it's already fuzzy, curled up with it's head between folded wings. The exact species is unknown.
