Painted some mushrooms for #UKFungusDay!

#sciart #fungi #illustration #natureillustration #gouache

A hand holding artwork featuring three fungi. On the left is a fly agaric with a bright red cap and a white stem. In the muddle is a bitter beech bolete with a brown cap and an orange-pink stem. On the right is a brown birch bolete with a brown cap and a white stem with spots.

Rhynie Chert is also the oldest preserved terrestrial ecosystem. The hot, mineral-rich water erupted from geysers periodically coated anything it landed on. It literally petrified the plants, animals and fungi. Their tissue was replaced with silica, which even preserved the individual cells.

Nestled in a mountain valley were hydrothermal springs and geysers, not unlike Rotorua or Yellowstone today. This place was home to some of the earliest plants that made it onto land. There is even evidence of fungal mycorrhizae linked to plant roots – just like we see today.

Back then, Scotland was in the middle of a continent called Laurussia, also called the ‘Old Red Continent’ (because of the Old Red Sandstone, a type of rock deposited in rivers that’s a deep burgundy colour). The Scottish Highlands were *high* (think Himalaya). Oh, and there were active volcanoes.

POV: you are in Scotland but it’s 400 million years ago and also you are a tiny springtail

#sciart #illustration #paleoart #kidlitart #natureart

A gouache illustration of the ecosystem of Rhynie Chert in Scotland.

In this illustration are a few inhabitants of ancient Rhynie: Asteroxylon (a green club-like plant) and Rhynia (plants with pink tips, where it released spores from) on land. In the water on the right, two red, shrimp-like Lepidocaris rhyniensis swim around Palaeonitella algae. They grow on top an older, already petrified ecosystem – the dark shapes are the solidified plant stems so typical for Rhynie Chert.

In the background are reddish mountains and a grey, rainy sky.

A very exciting #moth encounter in Edinburgh today: Clifden Nonpareil / Blue Underwing / Catocala fraxini

The only record in Scotland according to @inaturalist.bsky.social!

A deceased beige-grey moth with black and blue underwings lying on wet pavement. There is a thumb holding their wing down.

A deceased beige-white moth lying on their back on wet pavement. They have darker line and spot markings on the wings.

There is also a rock for every month to keep you company through the year! 2026 will feature metaconglomerate, komatiite, cross-bedded orthoquartzite, intrusive breccia, dunite, limestone, marble, agates and jaspers, blueschist, spherulitic pitchstone, geyserite and puddingstone 🪨 #illustration #art

An calendar open on February. The top page features a colourful illustration of a komatiite rock on a light background. The dates on the bottom page are underlain by pink bars.

The coloured bars underlying the dates correspond to the official chronostratigraphic chart, so it’s even easier to know where in the year / geological deep time you are on any given day!

An calendar open on December. The top page features a colourful illustration of a puddingstone rock on a black background. The dates on the bottom page are underlain by colourful bars.

Each day of 2026 corresponds to 12,512,329 years of our planet’s geological history. I highlighted different geological events throughout the months to help you visualise the unimaginable timescales of deep time (it makes for a great science communication or educational tool as well) #geology

A close-up of a calendar page for August. The dates are underlain by a pink bar. On the 9th, there is an event titled ‘the Boring Billion begins’. On the 17th, there is an event titled ‘multicellular life evolves’.

It’s hereee! My popular geological #calendar is back for 2026 – you can pre-order it now: vojtahybl.com/shop/p/2026-...

It isn’t your regular calendar, though. This is a journey into deep time: I took the whole timeline of the Earth (some 4.567 billion years) and condensed it into one year

Thank you! I am currently obsessed with ultramarine, so it features in most of my illustrations :D

My new illustration of an iconic tundra bird – the rock ptarmigan! It traces the colour of their feathers throughout the changing seasons

#sciart #nature

A gouache illustration of a male rock ptarmigan (Lagopus muta) sitting against ultramarine blue sky. There are four windows showing the bird change the plumage colour with the seasons. In autumn, they are grey to blend in with the rocks. In winter, the feathers moult into a snowy white. In spring and summer, the colour transitions into a mottled grey-brown to hide them in vegetation.

Really big lichens or a really small hiker? I’ll let you decide

A gouache illustration of boulder covered in bright green, white and mint green lichens. A tiny person with a backpack is walking on the boulder as if it was a hill.

WORLD-FIRST: Ground-breaking research published today in the Ornithologist Journal has, for the first time, translated common UK bird vocalisations into equivalent phrases in the human language.

The results tell us a lot!

Extracts below... 🧵

The front cover of a scientific journal titled Ornithologist, dated 1 April 2025. The main headline reads: “BIRDS: DECODED - Groundbreaking New Science.” Below that, a subheading says: “What are the UK’s birds really saying? Pioneering new research provides the answers.”

Cool cloud alert!

A grey, wavy cloud covering the whole sky. Light passes through it in places, creating lighter patches and a very dramatic look.

You’re walking in the coastal saltmarsh on a crisp morning at the tail end of winter. As you peek over the grassy hummocks, you spot a lone curlew feeding in the morning mist.

#natureart #sciart #illustration

A mixed media illustration of a curlew in a coastal mudflat. The sky is pink and grey, its colours reflecting in the water. The scene is framed in the foreground by dark green grassy hummocks.
