An infogrwphic of dimorphodon with in in lateral view, flying, in the centre, with a block of text top right and a geological timescale to the right

And infograpgic of Anchiornis in lateral view, with labels surrounding it, and a block of text I the top right, next to a geological timescale.

I'm making a series of infographics at the moment for some school groups, and, honestly, I'm really enjoying it!!!
They're learning about paleontology, and I was asked if I could provide some images of extinct plants and animals! Here are the first few: #paleoart #scicomm #education #paleontology

The first chapter of my PhD is published! If you're interested in how bones can be buried in floods, check it out in Paleobiology! (doi:10.1017/pab.2025.10087) And if you want to see the full scale experiments we ran, I did a summary video featuring a cover of When the Levee Breaks! #Taphonomy

[footnote:] This ground was measured by Dr, Carpenter of Lyme, and again in 1829, as I am informed, by Miss Mary Anning of Lyme, well known by her discoveries in fossil remains.' ; bottom left: extract of a letter of 15 December 1829 from Anning to Lyell with the information used in his 'Principles': 'I have made enquires of Dr: Carpenter he says that in the year 1800 he paced the Church Cliffs from a certain hedge and that (’they’ deleted) it was thirty paces to the edge of the Cliff (which is about 100 feet perpendicular height) it is fallen away from that hedge so as to leave about one yard between edge hedge and the edge of the Cliff having lost 29 yards in as many years.'

15 December 1829: in reply to an enquiry sent via their mutual friend Charlotte Murchison, Mary Anning provides Charles Lyell with information about the rate of erosion of Church Cliffs at Lyme Regis which he uses in his 1830 book, 'Principles of Geology', acknowledging Anning as his source.

A sandy, winding shore marked by huge, slanted stones. A band of algae and beached shells stretches down the shoreline. In the foreground, a pair of huge orthocones are beached. Beside them, a pair of trilobites wriggle in the sand.

A sail-backed Platyhystrix strides over a sand dune, carrying a lizard-like captorhinid in its mouth. Two other captorhinids peer from their burrows, surveying the carnage.

A variety of brightly coloured, dragon-like therapsids and reptiles prowl and swim about a primordial swamp forest. Crickets and a land-dwelling ammonite mingle with tiny turtle-like creatures and little lizard things, while various strange plants sprout up around them.

The child told me that I should print this in red, and I regret to inform you that he was correct.

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.

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

it appears plagiorizer William Toosey tries his shit again, that's my Propalorchestes in his "Journey through the Cenozoic".
I suspect this is just the tip of it. Many of these are just other people's work with a new texture slapped on top.
Lots of JRC art here.

I have come to the idea that we have to collectively, brutally, ritualistically kill Target just to show capital that we truly aren’t fucking around.

Comic. [Two people in front of projected satellite image. A small portion of the image is pixelated squares.] PERSON 1: Wait, when was this imagery taken? Is this censorship the work of the contractor? One of our people? *Foreign actors!?* PERSON 2 with ponytail: Do we know who’s operating a facility at that location? PERSON 1: We can’t find *anything*. [caption] My hobby: Setting up big colored panels in the middle of nowhere as a prank on remote sensing people

A Jurassic river and eroded embankment, in pencil (Doug Henderson)

The orthoceratoid Michelinoceras anguliferum, sporting a natty set of zigzags along its shelll, is probably better dressed than most of us today. Here, it's inflicting a fashion attack on a buried worm.

Cambrian polychaete Canadia spinosa is shiny, thanks to structural colouration.

A minor pile up between three migrating trilobites, Eldredgeops rana. The red dots on these animals are strange translucent lenses that might, it's speculated, be windows for pigmentation through their carapaces.

Two Dieneroceras subquadratum conversing about life as drifters in Triassic plankton. The banding pattern on their shells is fossil accurate, although the exact colours are unknown.
