I don't believe the human mind is equipped to process 2.75 million Snow Geese. I've seen about 250k before and it nearly broke me. ebird.org/checklist/S2...

I've never set out specifically to shoot mammals, but when I see them I try to get a shot. In honour of #WorldWildlifeDay I've collected a few of my favourites.

A sculpture of the shark-like fish Cladoselache swimming over a Devonian reef of coral and braxhiopods.

Cladoselache looked like a shark, but was a different sort of fish. The ancient, Devonian swimmer was a closer relative of today’s ratfish than to sharks. Still, it was an active predator. Cladoselache gut contents include fish that were swallowed tail first, caught and gulped down. 🧪

Southernmost occurrence of Purgatorius sheds light on the biogeographic history and diversification of the earliest primate relatives Fossils of the earliest known euarchontan mammals, purgatoriid plesiadapiforms, first appear during the aftermath of the Cretaceous/Paleogene mass extinction.

Our study on the southernmost occurrence of Purgatorius was published today in the Journal of Vertebrate Paleontology! Thanks to all the Brooklyn College undergraduates and DMNS interns who found these needles in a haystack of fossiliferous sediment!

Got into an argument not long ago with someone who still thinks "mackerel sharks aren't very smart".

Meanwhile mackerel sharks irl (esp the GWS):

What's scary about this story is the surveillance it hints at. This trans woman had changed her name, legally, but chose not to change her gender marker. She was apparently flagged in the DMV system as trans and her license was invalidated under a law that supposedly only concerned gender markers.

Result from the Koobi Fora #paleostream! This region on the east side of modern day Lake Turkana in Kenya is a treasure trove for fossils of the early Pleistocene and is most famous for many early human remains, with up to 6 species present throughout the layers...

FANTASIA dinosaurs

Boophis reticulatus, a brown tree frog with weird ridges on its back, perched on a serrated bright green Pandanus leaf.

Platypelis pollicaris, a little brown narrow-mouth frog with flecks of gold over its body, sitting atop a bright green leaf

A female Calumma oshaughnessyi, a large green and grey chameleon with diagonal stripes up its body, walking along a branch toward camera left.

A portrait of Liopholidophis dolicocercus (sorry if you’re using a system that reads these Latin names aloud!), a black, brown, and bright yellow snake. In my years working with snakes in Madagascar, I think I have never had a more cooperative subject. It was totally calm and posable!

Yesterday we hiked out of the forest after five days totally off-grid. Hard to believe what’s happened in the world in the last five days! I’m quite glad we were out of signal range and able to focus on just excellent frogs and reptiles. 🧪🐸🦎🐍🇲🇬

I think it was just YouTube videos now that I think back on it!

your moment of calm: sea potatoes! potatoes of the sea!

Teraterpeton, restored with a lizard-like, long-tailed body.

This also reminds me of my only Paleostream request way back in the early days before it really took off. Credit to @joschuaknuppe.bsky.social, of course!

I don’t usually pick favourites but this might be an exception!

Science of sex and gender being misrepresented by Trump officials, experts warn Scientists say crackdown on gender-affirming care could have impact on healthcare of all Americans

Major thanks to @melodyschreiber.com for interviewing me about what biology actually says about sex & gender

Unscientific attacks on trans rights are fueled by fascism, not science, and harm all of us - cis or trans

Size disparity in Azhdarchidae pterosaurs

In my ongoing research into the interplay of art and science at DinoLand USA, I’ve inadvertently rediscovered that Mike Trcic was a big Trump supporter and now I’m disappointed and frustrated.

I ask, again, is it really so hard for people to not be vile monsters? Does it take that much effort?

#marchofthemammals2026 Day 2: Maiopatagium furculiferum
Maiopatagium climbs up a tree to start a daring glide all over again.

Vector illustration of Miaopatagium furculiferum, a gliding haramiyid from the Jurassic of China. The small mammaliaform is hanging from a branch, climbing along with its long limbs. Its long fluffy tail is curled up above the branch. The animal is dark gray with a reddish face and a light underside. Its long fingers, nose and rounded ears are bare and pink

Second attempt (after like, 1.5 years) at UV unwrapping and texturing! Not unhappy with this at all - will definitely be delving deeper into this!

(don't ask me where the tongue is. I don't know either)

Hey if you're a bird photographer and you're using AI to "improve" your photos (like the image on the left, that changes the color of the bird, moves the eye, erases the tail, adds extra feathers that aren't there) know it makes me lose all respect for you, for just photo quality purposes alone.

Pencil sketch. Foreground: two dacentrurine stegosaurs drinking from a stream in front of an embankment covered in a Gleichenia thicket. Equisetum grow by the streamside. In the background an adult and juvenile Stegosaurus wander through osmundaceous ferns. A Ptilophyllum-type bennettite stands from among the ferns.
