Happy #PortfolioDay!
I'm a palaeontology student and mostly draw various unusual animals (both extinct and extant), and like doing interesting vegetation and backgrounds! I also do some more technical scientific illustration.

'Two Sirens'
Ink on Moleskine sketchbook paper, 128 × 206 mm, from 2020.

#ArtAdventCalendar
In an underwater scene, a sailfish, a mola, a mermaid whose flowing hair recalls marine algae, a dugong, and several golden trevally are grouped together in a vertically-oriented composition with some kelp against a black background. The illustration is drawn with intricate linework, with an emphasis on contours and varying line weight, and with areas of solid black ink.

Does anyone know much about Isoetes? Saw these in Gariwerd/the grampians which is supposed to have Isoetes drummondii and thought they possibly looked like them.

results of this week's #Paleostream flocking!!!

this week we sketched Camelops, Daemonosaurus, Panderodus, and Eustreptospondylus

#sciart #paleoart
a Camelops walks past a fairly newly formed tarpit nestled amongst thick vegetation Camelops is an extinct kind of camel that lived during the last ice age, unlike modern camels it had quite a slender snout and was slightly taller, it's unknown if it had a hump or not, however, we know that if it did have a hump it would only have one rather than two thanks to the shape of its back a Daemonosaurus slowly walks along the shallow muddy banks of a lake in the morning, it's slow movements are calculated as to not alert any nearby phytosaurs Daemonosaurus is a Triassic dinosaur who's position in the dinosaur family tree is still debated, some consider it a basal theropod, while others consider it a non-theropod saurischian related to dinosaurs like Hererrasaurus. it's a small dinosaur with a short face and large teeth, although, it's only known from a single skull, some neck material, and a few ribs three Panderodus kick up fine sediment by the shoreline of the ocean at night, they're illuminated from above by a light offscreen and outside of the water Panderodus is an unusual type of conodont (extinct jawless fish related to lampreys) which is flat like a stingray unlike other conodonts which are more eel-like. it's most well known for it's large conodont elements (mineralised tooth-like structures) which are simple and very proportionally large, some species of Panderodus have grooves on their conodont elements, which some scientists have proposed were for delivering venom, this would make conodonts the earliest venomous vertebrates a Eustreptospondylus swims along the surface of the water during the afternoon, most likely travelling to a nearby island. the camera is at the surface of the water with a small portion above showing the animal's head, while most of the camera is under the water where the body is. bubbles escape from the dinosaur's feathers as a wave submerges its body with only its head left above the water. the animal is swimming using a mix of its tail, legs, and arms. Eustreptospondylus is a theropod dinosaur known from Jurassic England when it was a series of scattered islands. Eustreptospondylus is only known from one juvenile specimen, the juvenile is around a meter tall at the hip. none of Eustreptospondylus' closest relatives preserve a nasal bone, so one scientists suspects that they could have had nasal crests akin to dinosaurs like Ceratosaurus or Guanlong, this isn't known for sure but i have followed this interpretation in my reconstruction of the animal.

“While Sleeping”
Intaglio and spit-bite aquatint

Look closely. You may see neuron trees and neurotransmitter constellations. ✨

#artadventcalendar #sciart #printmaking #neurons #neuroart
Black and white intaglio spit-bite aquatint print of an intimate night sky looking over the ocean with neuron trees and a sky full of stars and neurotransmitter constellations. In an edition of 10. by Kindra Crick Neurotransmitter acetylcholine as a constellation rising in the night sky with serotonin diminished and setting on the horizon as in the stage of sleep called REM. REM sleep is when your #dreams are most vivid and the mind is highly active while your body is paralyzed; except your eyes, which are in rapid motion.

Capturing the knobbly surface of this Trichodes alvearius was a real challenge #ArtAdventCalendar
A very fuzzy blue and orange beetle. It has a greenish blue head and thorax with a patterned orange and dark blue abdomen. Close up of the drawing, showing the knobbly surface of the beetle's abdomen. Plus a blue leg covered in yellow hairs.

Shores of the Cretaceous
#paleoart #sciart
A flat coastal wetland covered by small plants, a Ceratosuchops bends down to the ground far away, near the shoreline, a three-toed footprint filled with water sits in the dirt in the foreground. Two Anhanguera flying over a beach in the evening, the sky is bright pink and orange while the sun hangs just over a distant peninsula, bright red and yellow. One pterosaur glides calmly towards the sun, the other actively flies up from below to meet its partner. A flat sandy beach covered in patches of water and growing plants in the evening. A group of Bakiribu are walking through a puddle to filter feed, whole another casts a reflection in the water closer to the pov, flying past.

#PudgyHorse Lascaux Tribute 2. A companion piece to the first, following one of the other cave horses with a darker colour morph. Again, painted with pigments made by Mary Sanche from Cretaceous rocks from the Albertan badlands. From 2020.

#ArtAdventCalendar
Painting of my character, Pudgy Horse, a horse of baroque type appearance with luxuriant mane and tail, and deliberately exaggerated proportions, including short, slender legs with dainty hooves and an extremely generous girth; here painted in tribute to one of the famous horses in the Lascaux cave paintings using similar colours and simplified shapes.

A pair of Stegosaurus leisurely walking while a group of Hesperornithoides bicker in the foreground

I just think everyone needs to see Stegosaurus every now and then. Makes everyone happier 😊 This is an illustration of my licensing library and is available for non exclusive licensing.

I will have time for more deep sea sketches later this month.
For now, here are some old paintings/sketches.
#DeepSeaDecember 🐡
tiny painting of a bumpy snailfish behind the round cut out of a black passepartou. The fish is looking ahead and looks very kind and like its smiling. It is light pink. The background is blue. a watercolour sketch of a blobfish guarding its eggs. The fish looks kind and is sitting on a light blue and green abstract gound. In front are its eggs with little pink hearts around them. ink sketch of a lantern fish - sideview. the background are black ink splodges. Not visible here, but the fish glows in the dark. photo of a water colour sketch books with a pencil for size reference. The painting is the frontal view of Chaunacops. A very round red fish with fins that look as if it had tiny legs. It looks cute and like it is smiling.
