This #EarthDay I see that the Turtle Survival Alliance is launching their 5th Annual Turtle Month so I thought I would share these two prints they commissioned of turtles supporting the Earth featuring endangered turtle species of special focus: one for turtles from North America, and one for turtles from around the world. TSA works to prevent extinctions of these amazing and varied animals worldwide, so I was very glad to make art for this cause! 
On #EarthDay, one of my #BiodiversityShrine objects, a Cucujus cinnaberinus #beetle. Read more about the #sciArt project and why I celebrate this beetle: www.cronenburg.net/biodiversity/ (more photos). #reconnectWithNature #biodiversity #biodiversityLoss #art #paperArt #mixedmedia #rareSpecies
Born on this day: #physicist J. R. Oppenheimer (1904-1967). While best remembered for his role in the Manhattan Project, he was a giant of 20th century theoretical physics, nominated for a Nobel 3 times.
In 1927 he & Max Born greatly simplified how we predict electrons behaviour within atoms. The Born-Oppenheimer or adiabatic approximation is based on the observation that electrons are 1000s times lighter than nuclei, 1/n

The 2022 Korean translation of Locked in Time (by Dr Dean Lomax & published by Columbia University Press) commissioned me to colourise my 50 greyscale illustrations. "The Windswept Colony" shows a colony of nesting Hamipterus pterosaurs being disturbed by a storm.
Playing with this wavy spiral pattern and some warmer colors. Wow! I did not expect it to turn out so well. Yep, I did some on watercolor paper too. These might make it into my shop.
Here's an in-progress shot.
These are parts of a bookmark and an almost completely finished. Made from #nettle using #needlefelting .

In my Tucson, AZ yard I’ve had 6 Queen Butterfly larvae pupate & eclose as butterflies in the past month! Here’s my Perpetual Journal art of a Queen chrysalis, Northern Cardinal & Brittlebush.
Happy birthday to #geochemist Charles David Keeling (1928 - 2005) whose decades long observations of CO2 in air samples from Mauna Loa Observatory were some of the 1st direct data to show the human contribution to greenhouse effect & global warming. The ‘Keeling Curve’ (in copper & red) shows both the seasonal variations (the wiggles) & the strong upward trend with time as the greenhouse gas built up in the atmosphere.
Was talking to someone who teaches about horse anatomy, and they mentioned wanting a hyoid that was flexible (most models of it are rigid). I figured that might be a good model to practice 3d printing with both flex and rigid materials.
Turned out pretty neat!

Here's a study of the (probably) arboreal Suminia, commissioned in 2022 for a project I cannot talk about yet. It is a small therapsid, which I chose to make hairy but it might not have been.

Application period starts on May 1st.
Playing with harmonics in today's #inkyDays drawing. I also made some progress with this big piece I've been working on. I'm loving the colors!

I'm thinking about putting some of my fish drawings in my shop. Maybe later today.

The 2022 Korean translation of Locked in Time (by Dr Dean Lomax & published by Columbia University Press) commissioned me to colourise my 50 greyscale illustrations. "We Follow" shows a chain of migrating Ampyx trilobites.
SETI Institute in the News: March Roundup
https://www.seti.org/seti-institute-news-march-roundup
This month, the SETI Institute announced exciting news about research and innovations that expand our understanding of the universe and bring us closer to answering one of humanity’s most enduring questions: Are we alone?
Rhamporhynchus Muensteri 
Behind this barbaric name lies a small pterosaur... An adorable physiognomy that I have reconstructed in drawing from existing fossils!
It is neither a bird nor a dinosaur.
No feathers or scales, but a rather special coat of hair called pycnofibres
Membranous wings, supported by the 4th finger, which is particularly long
Loved working on this black rhino drawing. Played with textures, subtle tones, and even used a small makeup brush for clouds. I chose to indent paper for the grass over skin on the feet with an empty .3mm pencil! Did you know a group of rhinos is called a “crash”. #sciart
Almost ready! It will cost 30$ plus shipping.
