I’m a huge fan of @wikipedia.org and just spent about 4 hours uploading a handful of my photos. I hope someone finds them useful. Here’s one of those images. An ant and its funky Cordyceps horn.
An ant that’s been killed by cordyceps fungus. The ant is tangled in a strand of green moss. The fungus sprouts out of the back of its neck like a horn. Then it widens into a ball with a texture like poppy seeds clumped together, then continues again as a thin horn that bends down towards the strand of moss. If not for the horn, the ant looks like it’s eating the moss.

Did you know. That the meme-explosion that was the wooden model of Sacabambaspis (an Ordovician jawless fish) held at a Museum in Helsinki, was created by a pioneering Estonian fish paleontologist and palaeoartist, Elga Mark-Kurik. 🧵

When people say "There weren't many women in palaeontology/palaeoart in the 19 & 20th century" they pretend that women in the Central & East Europe did not exist, despite ladies ruling the show in that corner of the world for a century.

Red-whiskered bulbul (Pycnonotus jocosus) on African Tulip Tree (Spathodea campanulate), Bengaluru, Karnataka, India, from my sketchbook.

Black spiral binding of the sketchbook, brown bamboo brush with black bristles. Black and white ink handmade work on paper, foliage of African Tulip Tree (Spathodea campanulate) and buds of the same tree. A sharp pointy bill, white throat, black iris, crown with a crest pointing upwards a sign of alertness. Flowers of the same tree blooming behind the crest. Round body of the Red-whiskered bulbul (Pycnonotus jocosus) perched on a branch of the tree, bit of the bottom part of its tail is visible. Red-whiskered bulbul (Pycnonotus jocosus) on African Tulip Tree (Spathodea campanulate), Bengaluru, Karnataka, India, from my sketchbook. My health is slowly improving, and I’m rarely in my studio. Have made a few studies using ink in my new sketchbook, watching bulbuls, sunbirds, and flowerpeckers. Watching birds from my window and balcony soothes my soul and is something I anticipate each day. The occasional koel song is delightful to my ears. This year, it seems like spring is early, and my neighboring trees started flowering in full flow. Their bright colors are a sight to behold! The Neeru Kayi mara buds remind me of my childhood days of squirting them on friends, their powerful odor, color and the victims’ reactions are such days to relive again.

🐦Crows and their relatives are amazingly good at imitating sounds. Watch this video and the following ones in the thread to check it out
Also, follow Tay for more interesting threads about research on animal behaviour!

1/7 Vocal mimicry, robots, and music

The ability to mimic sounds could be extremely common among corvids. Here, it has been found in 39 species (30%), but it is predicted that it could be present in around 82% of them.

Micro Moon vs. Super Moon

Two views of the full moon: at left captured near apogee when the Earth-Moon relative distance is the greatest, so that the moon appears smaller in the sky, at right captured near perigee when the moon is closest to Earth, so it appears larger. Title reads "2025 Full Moon". The so-called Micro Full Moon pictured on the left was captured on April 13, 2025, when the Earth-Moon distance was 406,006 kilometers. The so-called Super Full Moon pictured on the right was captured on November 5, 2025, when the Earth-Moon distance was 356,979 kilometers.

Uma nova espécie de pterossauro do Araripe, encontrada dentro de um vômito fossilizado de dinossauro 🤍. A natureza é linda! Kkk

Seja bem-vindo, Bakiribu waridza!

Acesse o artigo: www.nature.com/articles/s41...
Digital paleoart scene showing two pterosaurs with long, comb-like teeth standing in shallow water, using their jaws to filter food. Several similar pterosaurs fly in the background and a large theropod dinosaur resembling Irritator walks along the shore chasing them. The landscape is semi-arid with distant mountains under a cloudy sky. Photographs and interpretative drawings of a fossil regurgitalite from the Romualdo Formation (Araripe Basin). Panels A and B show part and counterpart of an oval limestone concretion containing disarticulated and partially digested remains of pterosaur bones and fish. Panels C and D are line drawings highlighting bone clusters and digestive residue, illustrating the internal organization of the regurgitated mass.

New filter-feeding pterosaur dropped and it was found in dinosaur vomit!
alinemghilardi.bsky.social Aline Ghilardi @alinemghilardi.bsky.social · 1d
The name Bakiribu waridza derives from Kariri words: bakiribú (“comb”) and waridzá (“mouth”), referring to the animal’s comb-like dentition. The name also honors the Indigenous peoples native to the Araripe region, Brazil.

Waning Hours
Digital Drawing. A large dicynodont (Ischigualastia) is knelt on the ground, struggling to lift itself up with its forelimbs. A gash is visible on its thigh. Three small dinosaurs (Eodromaeus) observe from nearby. The sky is a pale blue - the sun has already moved below the horizon.

While the Magellanic Clouds shine upon the Chilean Desert, two VLTI Auxiliary Telescopes point up to the sky — all together reminding us of how small we are as humans compared to cosmic objects & the telescopes we observe them with.

Another species no longer on the global Endangered list:
Humpback whales (Megaptera novaeangliae).

A few decades after a Star Trek movie where the central conflict was the total extinction of the humpback, their numbers are rising fast enough to put them at "Least Concern" on the IUCN Red List.

And here we go, result from the Judith River Formation #paleostream! This late Cretaceous formation might be full of charismatic megafauna but it is currently understudied and a total mess when it comes to stratigraphy. In this scene I wanted to focus on two aspects...

Palaeoplatyceros hispanicus- a muntjac-like deer from the Middle Miocene of Spain. Numerous antlers found on Otero Hill in Palencia allow to trace the age-related dimorphism of these animals. The illustration shows an adult, possibly even old, animal and a younger deer in the background.

Foggy morning in Late Pleistocene Patagonia.

#Art #SciArt #artbyjulio
A scene depicting the Patagonian scrubland in the early morning, dotted with araucarias and framed by foggy mountains in the background. A pair of Macrauchenia, four guanacos and a patagonian mara are seen among the grass. A Megatherium walks by further away and a crested caracara flies over the scene.

While I don’t think anyone has made a specific designation between “larval” and “adult”, in the moorish idol, I’m going to label this one “post-larval”
