This #FossilFriday we @camzoology.bsky.social are in our first year Evolution undergrad fieldcourse @fieldstudiesc.bsky.social Dale Fort including the fabulous Marloe Sands Silurian Fossil site 😍

Close up with a beautiful nudibranch on a rocky reef. The lower half of the image is a palette of swatches made from the nudi's vibrant colours.
Once upon a time I just admired nudis and sea slugs.
But it was not enough. Now apparently I'm creating an R package to celebrate their colour palettes? 😅
First up, my Sydney fave, Hypselodoris bennetti.

A photo of a white lighthouse with a black top standing among green trees and palm plants during sunset. The sky features strikingly layered, wavy clouds with shades of blue and yellow.
One of the most surreal skies I have ever witnessed, as vibrantly blue undulatus asperatus clouds rolled over the St. Mark's Lighthouse at sunset to create this dreamy scene. #Photography
The new Plankton Project website it LIVE! At the very least, just check out the adorable animation on the home page 🥹. Link in our bio. Thanks to @big-pixel.com for all your hard work!

MOAR #okeanos midwater Magic! jellies, siphonophores and more! oh my! from 2017, the Musicians Seamount expedition youtu.be/s3VbKydtSQ0?...
Gray siltstone surface with a star-shaped (five-armed) protrusion representing the natural cast of a sea star "starfish" that buried itself into a muddy surface below it. Two of its ends are rounded and the other three have broken ends; fine textures in each arm hint at movement of the arms and their tube feet.
Hard to pick a favorite fossil for me, but for your 50th birthday, here's one I think you'll enjoy the most: a sea-star resting trace preserved as a natural cast, from the Late Ordovician Sequatchie Formation in northwest Georgia (scale in cm). 🧪🪨⚒️🐾
A collection of prints on 8” x 8” square of white washi paper with a blue S-shaped velvet worm, resembling a many-legged caterpillar with two antennas and a pattern of spots. Along its length there’s a central darker blue stripe. There look to be a grid of 12 prints.
I couldn’t resist the pretty blues of the New Zealand/Aoetearoa velvet worms, so I selected a different species than suggested for #InsertAnInvert2024. Here are my 8” x 8” linocuts drying….

How gorgeous are these Hydrozoa medusae?! These are a first for me - medusae from the family Rathkeidae. You see the bulbous bits inside the bell? They’re little buds of new medusae! These hydroids can asexually reproduce in this way. How cool is that!!

A newly discovered fossil site in southwest China has transformed our understanding of how complex animal life emerged on Earth, revealing that many key animal groups had already evolved before the start of the Cambrian Period

Polacy na Dalekim Wschodzie, Grochowski, Kazimierz, Harbin 1928
This flag symbolized the Chinese Eastern Railway (CER), a joint Sino-Russian venture established under the 1896 Li–Lobanov Treaty, which granted Russia a concession to build a railway through Manchuria. Adopted in 1897, it served as the official emblem for the Russian-managed company, displaying its authority at railway stations and facilities like those in Harbin.
Cossacks guard the CER bridge over the Sungari River in Harbin during the Russo-Japanese War (1905)
A thread 🧵 on Polish palaeontologists in Harbin
There used to be (~30k strong) Polish population in the city of Harbin (哈尔滨), during Russian occupation of North China & partition of Poland. The population was composed of Socialist Poles who were banished as punishment for anti-Tsarist uprisings.
A green sea anemone - *Anthopleura xanthogrammica* - basks in a tide pool. Though its bright green color mostly comes from animal pigment, it also hosts both dinoflagellate and green algal unicellular symbionts. I just love the purple tentacle tips contrasting with the vivid green.
Who needs anemone? #MarineLife #Invertebrate 🌊🦑💚💜

All my Acartia have been sorted, measured and added to the Norfolk Plankton Image Library. If you’re interested in this dataset let me know! 2023 - current, Norfolk Coast (various locations), A. clausi, A. bifilosa, A. discaudata. Images of over 350 specimens. All with metadata #marineplankton 🦑
A collection of “Tasteful Nudi’s” (part 1 of 4)
Nudibranchs are a type of sea slug - most of the 3000+ species share a few key traits - they riotously colored, slow, small, and have only one defense - chemical.
All shot in my first month of Bali in Sept2025 - lots more where this came from!
A graphic titled "States vs. Periodic Table" compares the number of US states (50) to the number of known chemical elements (118) and the number of naturally occurring elements (98). The image uses a stylized periodic table layout where each cell represents a chemical element. Some cells are highlighted or contain text that might relate to the comparison, though the specifics are not fully discernible. The graphic suggests a visual analogy or comparison between the two sets of numerical data.
Because…why not?
I find it can be sometimes difficult to develop an original composition, color palette etc for aquatic #paleoart. Here's a thread of some inspiring #wildlifephotography:
"The Night Shift" - molluscs moving on coral reef to graze as night falls & grey reef shark cruises (Laurent Ballesta)
A few weeks ago CBC reporter Sheena Goodyear reached out to me for comment on the new Spinosaurus paper. I said I couldn’t, because of Epstein connection Nathan Myhrvold’s involvement with it. We got to talking about how paleontology - especially dinosaur research- remains hostile to women. 🧪
A new species of polychaete worm is described from the Porcupine Abyssal Plain in the northeast Atlantic at ~4850 m depth.

The teeth of the Californian Horn #shark (Heterodontus francisci) are incredible - this CT image by @ellanicklin.bsky.social shows the first rows of the juvenile dentition. How scary can this shark be when it has jazz-hands for teeth!? 🦈🦷 @ufresearch.bsky.social 👐
