Some throwbacks to my Devonian sketchbook for sea sponges, sea stars, brittle stars, urchins, edrioasteroids, and crinoids. My style in colored pencil was very naturalist

Scientific illustration practice: Macheiramphus alcinus (bat hawk).

The coloration is based on recent data indicating countershading in ichthyosaurs, which while not surprising is still really cool. I mainly looked at modern dolphins for inspiration, as their skin is the closest analog.

Progress on some sketches for a couple of projects I'm working on for the D'arcy Thompson zoology museum! .

Today marks the 1-year anniversary of when I 1st shared my on social media! The inaugural Instagram post was of the nektobenthic Paleozoic cephalopod Aphetoceras, so I thought I'd recreate it:

I hear there's a new going around, good thing I have a new sauropod! Feat. Euhelopus (2017), Patagotitan (2018) and Camarasaurus (yesterday) 🦕

Camarasaurus lentus, one of the most common and well-known sauropod dinosaurs. Probably not much to say that you don't already know.

An original illustration of a bee fly, Bombylius major. Insects and spiders that have hair are adorable... add a really long snout, and OMG ❤️

Did my best to make the sabre-toothed metatherian Thylacosmilus look marsupial related, and not just a discount felid or store-brand thylacine. This ambush predator is known from the Miocene-Pliocene of S. America.

The very rocky process in coloring Teraterpeton. Went from “jungle demon” to “caramel latte” to the final result (“plague doctor iguana”?)

Last (but not least) allokotosaur: Teraterpeton!!! This charming fellow lived during the Late Triassic in what is now Nova Scotia. Features of note include a long, toothless snout and blade-like claws.

The last in the Turkey Vulture series is just a lovely headshot of the bird! Turkey Vultures are the most common vulture here in the states!

My most detailed entry into the Proboscidea series was the American mastodon. I painted as much of the fur as possible. https://t.co/PhJrTVUk21

Palaeoloxodon falconeri is a great example of the crazy size disparity that can occur within the same genus. I didn't know this extreme was possible for mammals https://t.co/x52Tj8s0aH
